STAHL More than 12 years ago, R. STAHL SCHALTGERÄTE GMBH brought the ICS MUX field bus system onto the market as the first manufacturer to introduce an I.S. bus system world-wide for input and output of signals within the hazardous area (Zone 1). This bus system consists of a master station installed in the control room as the coupling partner for automation units together with several completely explosion protected on-site stations or field stations (VOS) installed directly in the field (Zone 1). The connection between the master station and field stations is made via a single coaxial cable. One of the many highlights of this I.S. bus system is that all the subassemblies of the system - even the power packs – can be plugged or unplugged during operation without affecting the explosion protection. This bus system enabled R. STAHL to present users from the chemical, petrochemical or pharmaceutical industries with an apparatus that can be installed in the hazardous area but can be operated like an apparatus installed in the control room. This provided the ideal combination of the technical advantages of field bus technology (simple cabling structures, powerful diagnostic options) with the resulting economical advantages (lower investment costs). The VOS 200 system variant based on this bus system was introduced in 1993 as a supplement that includes all the recognised advantages of the field bus system and was developed under two fundamental aspects: - Field bus solution for low signal volumes or decentralised automation units that do not require a master station. - Standard solution to enable the simple implementation of future standardised bus systems. The VOS 200 can be coupled to the most varied automation devices in either a redundant or non-redundant configuration as a point-to-point connection or (multi-drop) bus connection. The principle element of the VOS 200 system variant is the 9503 central unit (CU). This multi-processor subassembly with dual port RAM takes over both the data traffic from and to the connected I/O subassemblies as well as the upwards communication to distributed control systems or programmable logic controllers. The various coupling options of the VOS 200 were expanded again in 1997 and supplemented to include a PROFIBUS DP connection. A further step for optimising this field bus technology was realised with the development of the IS1 system. Experience gained from previous systems was used to implement a new, more flexible and more powerful product for the user as well as to provide a solution to all types of automation tasks. The following section describes the system characteristics of the IS1 system when coupled to an automation system via the PROFIBUS DP. IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 3 Operating Instructions PROFIBUS DP interface for IS1 1 System Overview 1.1 Connection principle of IS1 field stations to the PROFIBUS DP As an off-the-shelf explosion protected mounted unit, the IS1 field station can be installed directly in the hazardous area (Zone 1 or Zone 2). It can also be installed in the safe area. The adjacent diagram shows a Zone 1 solution. The IS1 field station has two serial interfaces. One of them is used to connect to an automation system and the second serial interface can be used as a bus-capable maintenance interface for the configuration, error diagnosis and communication with HART field devices. Several IS1 field stations can be used in the hazardous area to form a Profibus DP network that is connected directly - both hierarchically and topologically - with the Profibus network in the non-hazardous area. The following applies to Zone 1 installations: From a safety-engineering aspect relating to explosion protection, the field bus isolating repeater for the Profibus takes on the function of a “barrier” between the ex area and non- hazardous area. In the same way as the Profibus installed in the safe area, the Profibus installed in the hazardous area conforms entirely with the European norm, EN 50 170, with the special feature of I.S. protection. In such a Profibus network, the IS1 field station behaves hierarchically as a Profibus slave where the configuration of the field station is performed via the Profibus master. Optional extended diagnostic and parameterising functions can be provided via a PC-supported configuration program (I.S. Wizard). IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 4 Operating Instructions PROFIBUS DP interface for IS1 1.2 Transmission structures Fig. 2 shows the possible transmission structures of several IS1 field stations in a Profibus network. IS1 field stations can be connected to the Profibus in the hazardous area as well as in the non- hazardous area. Both fibre optic technology as well as bus structures in multi-drop cabling configurations are available in the hazardous area. IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 5 Operating Instructions PROFIBUS DP interface for IS1 1.3 Access procedure of the PROFIBUS DP Class 1 masters are masters that are allocated one or more slaves. Only class 1 masters have write (setting the outputs) and read (reading inputs) access to the slaves allocated to them. Class 2 masters only have read access to slaves. Each slave can have only one class 1 master but several class 2 masters can be available for each slave. A network can have several class 1 masters. However, only one class 1 master can have write access to the slaves allocated to it. Masters can be both class 1 masters for one particular slave while they are class 2 masters for other slaves. Example: Slaves A1 and A2 are allocated Master A as their class 1 master. Master A has no slaves allocated to it as class 2 master. Master B is allocated as the class 1 master of the Slave B1 and as the class 2 master of both Slave A1 and Slave A2. Profibus DP services Data_Exchange Cyclic data exchange with a class 1 master, e.g. an automation system with one slave. RD_Inp Reading of the input data by a class 2 master, e.g. PC for configuration and diagnosis or another automation system. RD_Out Reading of the output data of a slave by a class 2 master. Slave_Diag Diagnosis data are sent to the class 1 master. Set_Prm Configuration data are sent by the class 1 master to the slave (IS1). Chk_Cfg Transmission of configuration data by the class 1 master to the slave and checking of the configuration data received by the slave. Get_Cfg Request of a class2 master to read the current configuration data of a slave. Set_Slave_Add Not supported! The slave address is set by operating keys on the CPM of the IS1 field station. IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 6 Operating Instructions PROFIBUS DP interface for IS1 2 Commissioning 2.1 Overview Planning of the complete PROFIBUS network: - Which masters are in the network - Which slaves are in the network - Selection of network topology and network physics (repeaters, glass fibre links ...) - Selection of the baud rate depending on lengths of cable, volumes of data and time requirements - Unique allocation of the PROFIBUS addresses.

WIZARD on a PC connected via the service bus. IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 7 Operating Instructions PROFIBUS DP interface for IS1 2.2 Engineering limits The general regulations according to the IS1operating instructions apply to the engineering of an IS1 field station. The use of the PROFIBUS DP interface gives rise to the following additional engineering regulations that must be observed in the PROFIBUS DP Slave implementation of an IS1 field station: The data volume for the IOM of a IS1 field station that can be transmitted is limited in the PROFIBUS DP to: max. 112 bytes of input data + max. 80 bytes of output data *1) Thus, the maximum possible number of IOMs in a field station is limited. An expansion of this data area was made in junction with the extended parameter set of IS1 (see separate instructions). The following table shows the length of the cyclic data of different types of IOM: Cyclic data length [bytes] Module selection text in the GSD file PROFIBUS (standard param. set: GSD V1.xx) identifier [HEX] Input Output 9440/12-01-11 CPM Z1 Stahl 24V 0 0 00 - - - - 9440/12-01-11 CPM Z1 Stahl 24V Red 1 1 30 - - - - 9440/15-01-11 CPM Z2 Stahl 24V 0 0 00 - - - - 9440/15-01-11 CPM Z2 Stahl 24V Red 1 1 30 - - - - AKF 9440/22-01-11 CPM Z1 PNO 24V 0 0 00 - - - - 9440/22-01-11 CPM Z1 PNO 24V Red 1 1 30 - - - - 9440/22-01-21 CPM Z1 PNO 230V 0 0 00 - - - - 9440/22-01-21 CPM Z1 PNO 230V Red 1 1 30 - - - - 9460/12-08-11 AIM 4/8 Exi 16 0 42 47 30 03 - 9461/12-08-11 AIMH 8 2w Exi 16 0 42 47 30 05 - 9461/12-08-21 AIMH 8 Exi 16 0 42 47 30 06 - 9465/12-08-11 AOM 8 Exi 0 16 82 47 40 09 - 9466/12-08-11 AOMH 8 Exi 0 16 82 47 40 0b - 9470/12-16-11 DIM 16 NamExi 4 0 42 83 11 0d - 9470/22-16-11 DIM 16 NamExi 4 0 42 83 11 0d - 9470/22-16-11 DIM 16+CF NamExi 8 1 c2 00 87 12 0d 9471/10-16-11 DIM 16 24V 4 0 42 83 11 0f - 9471/10-16-11 DIM 16+CF 24V 8 1 c2 00 87 12 0f 9475/12-04-11 DOM 4 Exi1 0 1 82 00 20 12 - 9475/12-04-21 DOM 4 Exi2 0 1 82 00 20 13 - 9475/12-04-31 DOM 4 Exi3 0 1 82 00 20 14 - SKF 9475/12-08-41 DOM 8 Exi1 0 1 82 00 20 16 - 9475/12-08-51 DOM 8 Exi2 0 1 82 00 20 17 - 9475/12-08-61 DOM 8 Exi3 0 1 82 00 20 18 - 9475/12-07-71 DOM 7 Exi4 0 1 82 00 20 1f - 9475/22-04-21 DOM 4 OD Exi2 0 1 82 00 20 24 - 9475/22-08-51 DOM 8 OD Exi2 0 1 82 00 20 20 - 9475/22-08-61 DOM 8 OD Exi3 0 1 82 00 20 21 - 9477/10-08-12 DOM 8 Rel 0 1 82 00 20 19 - 9477/12-08-12 DOM 8 60V Rel Z1 0 1 82 00 20 22 - 9477/12-06-12 DOM 6 250VRel Z1 0 1 82 00 20 23 - 9477/15-08-12 DOM 8 Rel Z2 0 1 82 00 20 1e - 9480/12-08-11 TIM 8 R Exi 16 0 42 47 30 1a - 9481/12-08-11 TIM 8 mV Exi 16 0 42 47 30 1c - AIM 4/8 (9460/.., 9461/..) 16 0 57 - - - - AOM 8 (9465/.., 9466/..) 0 16 67 - - - - AKF DIM 16 (9470/.., 9471/..) 2 0 11 - - - - DOM 4/8 (9475/..) 0 1 20 - - - - AKF: standard identifier format SKF: special identifier format ( is not supported from all DP masters, but should be used preferred ) The telegram length of the cyclic input and output data of a field station depends on the type and number of IOM used. The field station limits mentioned above must also be observed here. IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 8 Operating Instructions PROFIBUS DP interface for IS1 Example: If only AIM modules are used in an FS, each with 8 AI (2 bytes per AI = 16 bytes of input data per AIM), a maximum of 112 bytes / 16 bytes = 7 AIM can be projected in this FS. Moreover, further limitations of the number of IOMs, the maximum number of signals and the maximum number of slaves in a network ... depend on the performance of the DP master used. Thus, the limits of the DP master used must also be taken into account during the engineering. *1): using redundant CPM: Using redundant CPM the status- and controlregister of the CPM can be transmitted cyclicaly in addition to the data of the IOM. In this case the following maximum telegram length is supported: max. 113 Byte input data + max. 81 Byte output data Attention! The maximum telegram length of IS1 fieldstations has been extended using the Extended Parameter Set of IS1 see: ´ New features with the Extended Parameter Set´ IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 9 Operating Instructions PROFIBUS DP interface for IS1 2.3 Configuration of the DP master The documentation of the master will describe the exact procedure for the parameterisation of your master. As a result of the high degree of standardisation of the PROFIBUS DP, the configuration of the network is performed in a very similar fashion - even for the products of different manufacturers. The following procedure usually applies: A GSD file is supplied with the IS1 field station. This file contains all the information important for the master on the communication behaviour of the IS1 field station. The GSD file is usually read by the configuration software of the master. The configurator of the master takes the information on the module types possible in an IS1 field station from the GSD file. Configuration rules: - The CPM module (module no. / slot = 0) must be configured first. Even if redundant CPMs are used, only the CPM in slot 0 needs to be configured as, from the point of view of the master, there are two slaves each with one CPM. - Configuration of the IOM slot coded from slot 1 (module no. 1) according to the IOMs that are planned or are present in the system. - Only PROFIBUS Identifiers ac. the list in chapter 2.2 are allowed. - max. telegram length (112 (+1) Bytes Input and 80 (+1) Byte Output data) is checked - max. number of IOM (max. 16) is checked - the number of parameter bytes must fit to the number of configured IOM´s. (10 Byte for CPM + 5 Byte per IOM) - Byte 6 of CPM parameters has to be ´1´ for check of version conflict GSD / CPM. The configuration data and parameters required for the slave are transmitted from the master to the slave during the start-up process. Attention ! The CPM checks the a. m. engineering and configuration rules. -> In case of error, the CPM does not go into the “Data_Exchange” state. The “Cfg_Fault” message is transmitted in the diagnosis telegram. If none of the errors listed above occur, the CPM accepts the configuration data and goes into the “Data Exchange” state with the DP master. If the modules that are plugged in do not correspond to the modules configured in the master, those modules that do not do not correspond with the configuration data of the master are displayed in the “Device-specific diagnosis” area. The signals of the wrongly configured modules are considered to be garbled (corrupted) and processed according to the parameterised behaviour that applies if an error occurs. All signals of modules which correspond to the modules configured in the master are in operation (signals are updated cyclically).

IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 11 Operating Instructions PROFIBUS DP interface for IS1 2.4 CPM redundancy 2.4.1 Functions An I. S. 1 fieldstation can be equipped with a primary and a redundant central unit (CPM), whereby each CPM has its own independent PROFIBUS DP interface. From the point of view of the automation system, each fieldstation has 2 separate DP slaves, and both are involved in the cyclical data exchange with the DP master. Thus, there are two independent transmission paths between the DP master and the fieldstation. These two transmission paths are monitored for proper and error-free operation by user software in the automation system. In addition, one of the transmission paths is selected to transmit the useful data. The CPM linked to the transmission path selected by the AS is made ‘active’ by transmitting a control register from the AS to the CPM. Of course, data can also be transmitted through the other (inactive) transmission path. However, it only helps to monitor the connection. Data transmitted here is not used. Only the active CPM handles the data traffic to the fieldstation I/O modules. The active CPM monitors the inactive CPM and likewise provides it with the current input data. For programming of the user software in the automation system a seperate document is available. 2.4.2 Configuration and parameterisation of the IS1 fieldstation in the DP Master The superordinate automation system provides two DP slave devices on the PROFIBUS with address n (primary) and address n+1 (redundant). Both slave devices must be configured separately in the DP master configurator with identical I/O arrangements and parameterised with identical slave parameters. (Recommendation: first configure and parameterise the primary slave and then copy the complete slave to slave address n+1). Consequently, there is a separate memory area with the respective associated I/O data for each of the CPMs (primary and redundant). For the CPM parameters, set the parameter ‘CPM redundant = Yes’ in the DP master configurator. When configuring a field station with CPM redundancy, the CPM with the additional ‘Red.’ from the module list of the GSD file must be configured as the first module in both slaves (Module No. / Slot = 0) (for example, ‘9440/..-..-.. CPM Zone 1 Red.’) in the DP master. The CPM module for redundancy has 1 byte input data (status register) and 1 byte output data (control register), which is transmitted in the cyclical data area from PROFIBUS DP. These registers help to control and monitor the redundancy by means of the AS. Even if redundant CPMs are used, you must configure only one CPM in slot 0 per field station, as from the point of view of the master, there are two slaves with one CPM each respectively. IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 12 Operating Instructions PROFIBUS DP interface for IS1 2.4.3 Prepared Redundancy It is possible to use only one CPM and one empty slot for the redundant CPM in future (prepared redundancy). With the parameter ´CPM redundant = Yes / No´ and the different CPM Modul descriptors the following configurations are possible: (available with CPM firmware V01-20 or higher) not Redundant Redundant Operation not allowed Operation Operation Parameter No No Yes Yes ´CPM redundant´: 9440/1.-..-..

(with status- and controlreg.) (without status and controlreg.) (with status- and controlreg.) The CPM can be located on all slots of the rail ! To prepare a later redundancy (prepared Redundancy) the CPM has to be located on redundant slots (1 red, 3 red). The Slave address of the Configuration error on CPM will be incremented (+1) by using the CPM in PROFIBUS DP, these slots. no Data Exchange, control of the redundancy The left slot beside the CPM remains empty for later behaviour: Diagnosis message via the control register extension with the redundant CPM. The right slot ´Redundant CPM descriptor from the AS required. beside the CPM is the slot 1 for IOM modules. required´ in device specific diagnosis. The content of the control register is not *1) considered.. The Statusregister is updated. *1): It is possible to install two CPM on one rail, configure both ´not redundant´ and put only one of both into Data Exchange. Without or with prepared redundancy only one CPM can be put to Data Exchange, because the CPM is getting acitve without control register. If two CPM are used and both are in Data Exchange they are toggling between active and inactive (app. 4 sec). IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 13 Operating Instructions PROFIBUS DP interface for IS1 2.5 Line Redundancy The flexibility of the Remote I/O System IS1 has been further improved. To substantially enhance its availability even if a transmission path has been broken, the Line Redundancy has been implemented. The function is suitable for non-redundant Profibus Masters. In order to do this, the two fieldbus isolating repeaters, Type 9185, are interconnected at the X interface with 2 a Profibus DP cable via Sub D connectors and connected to the PROFIBUS Master (PLC, process control system (DCS)). One Profibus DP cable with Sub D connector is connected to each X interface of the 9185, 3 and connected to the two X and X interfaces of the CPU & Power Module (CPM), Type 9440. 1 2 The Profibus line between the fieldbus isolating repeaters and the IS1 field stations (CPM, Type 9440) thus has a redundant structure. Data is exchanged via both channels and is evaluated in the CPM, Type 9440, with an internal logic. Data arriving first is prioritised and the other data is rejected. If one line suffers a fault, data transmission continues undisturbed between automation system and IS1 field station. If the disturbed channel is operational again, redundant data traffic resumes automatically. The outputs in the connected I/O modules revert to safety position after the hold time configured user-specifically only if both transmission paths between PLC and the CPM, Type 9440, are broken. If a disturbed channel is operational again or if both disturbed channels are operational again, data communication resumes automatically. Faults on the two redundant transmission paths are signalled in the PROFIBUS diagnosis telegram and optionally in the I.S. Wizard.

This provides the advantage that all the parameters of the field station can be accessed in easy-to-use screen masks in the configurator of the DP master. If the configurator of the DP master only supports older GSD formats, the parameters can only be edited as hexadecimal number sequences. 2.7 Bus segments A PROFIBUS network is based on RS485 bus physics with a twisted pair cable as the transmission medium. A network can consist of several line-type segments that are connected by repeaters or optical transmission routes. The 9185/11-35-10 field bus isolating repeater can be seen as a repeater that connects a non-hazardous bus segment with an I.S. bus segment (RS485IS). 2.8 Length of bus segments and stubs Stubs are bus lines that branch off from the line-type main cable of a bus segment, e.g. via a conduit tee. Stubs should be avoided whenever possible. Due to the line physics of the bus cable, the sum of the lengths of the stubs in a bus segment is limited. The following table shows the maximum lengths of stubs that are allowed for each bus segment. The table is valid for both non-I.S. and I.S. bus segments. Max. length of a bus segment when Max. sum of the lengths of Baud rate using a standard PROFIBUS cable stubs per segment (type A) 9.6 to 93.75 kbaud 96 m 1200 m 187.5 kbaud 75 m 1000 m 500 kbaud 30 m 400 m 1.5 Mbaud 10 m 200 m IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 17 Operating Instructions PROFIBUS DP interface for IS1 2.9 Bus termination Every RS485 bus segment must be terminated at the first and last device of a segment with a bus termination resistor. As the bus terminations draw their auxiliary voltage from the PROFIBUS devices, make sure that the stations terminated by termination resistors are always supplied with voltage during start-up and operation. All devices without a bus termination can be plugged into or out of the bus during operation without affecting the data traffic between the other devices. Example of a possible bus configuration with termination resistors: Attention ! Standard (non Exi) PROFIBUS SUB-D connectors are not allowed for PROFIBUS Exi segments. Only sub-D connectors approved by R. STAHL may be employed for the Ex i segment of the fieldbus. End of line resistor in Ex i segment see operating instructions: Project Planning, Installation and Commissioning of the RS 485 Fieldbus System from R. STAHL for Non- Hazardous and Hazardous Areas. IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 18 Operating Instructions PROFIBUS DP interface for IS1 2.10 PROFIBUS address of the IS1 field station The setting of the PROFIBUS address of an IS1 field station is performed by means of operating keys on the CPM module. An address within the range 0 to 127 can be given here. Parts of this address area are reserved for specific tasks although the address area of 1 to 123 is freely available in most master systems. Please note that addresses may only be allocated once in a PROFIBUS network. The address that is set on the CPM is also valid for addressing the I. S. 1 field station on the service bus. (see also the CPM operating manual) 2.11 Baud rate The central unit of the IS1 field station (CPM) and the fieldbus isolating repeater 9185 (set switch to pos.0 = autobaud detection) have an automatic baud rate detection for the PROFIBUS DP interface and can set itself to all standardised PROFIBUS baud rates within the range 9.6 kbaud to 1.5 Mbaud. Attention ! The selected baud rate for the 9372 or 9373 field bus isolating repeaters must be set on DIP switches. 2.12 Pin allocation of 9-pole D-type connectors: The CPM and the field bus isolating repeaters (9185, 9372/21 and 9373/21) have 9-pole D-type sockets with the following allocation for connecting the PROFIBUS: Pin no.

During the start-up process, the master and slave exchange information on data block length, structure of data blocks (assignment to modules), parameters and Watchdog status ..... Two different start-up behaviours of class 1 masters can be differentiated: 2.13.1 Slave is configured by the master: (Procedure predominantly used by class 1 masters (Automation Systems)) The class 1 master transmits configuration data to the CPM by means of the "Chk_config" service. This service checks the data for compatability. After checking this successfully, the CPM takes over the new configuration data and subsequently responds to "Get_Config" telegrams with the new data. Hence, the slave adapts itself to the configuration of the master. This start-up behaviour requires the parameterisation of the data block length and module assignment in the class 1 master. The configuration tools of the master are available to do this. They enable the configuration based on the GSD file (device specific file) of a slave. The implementation of the service bus and the I. S. Wizard PC software can be dispensed with in this operating mode. However, these tools and the HART Management System can be used if required. 2.13.2 Master configures itself with data from the slave: (Predominantly used by class 2 masters as diagnostic and parameterisation tools) The data block length and module assignment are not parameterised in the configurator of the master in this variant. This information is read by the master from the slave during the start-up process using the “Get_Config” service. Only the allocation of data to the internal registers needs to be either defined in the master or automatically allocated. If the CPM is involved in cyclic data exchange with a class 1 master, the module configuration defined by the class 1 master is used vis-à-vis the class 2 master. If the CPM is not involved in cyclic data exchange with a class 1 master, empty modules are transmitted to the class 2 master by means of the “Get_Config” service. The real present modules can not be read in this operation mode.

In this case, the data blocks of the individual modules are grouped into telegrams in the order defined in the configuration software of the PROFIBUS master. If empty modules are configured, no data is transported in these locations of the data telegram and no diagnosis data is generated for the associated slot. 3.2 Parameterisation of the IS1 field station and the IOM 3.2.1 New features with the Extended Parameter Set The functionality of the IS1 Remote I/O-System has been extended with the extended parameter set in following points: • Increased telegram length: - 239+1 Byte Input data (112+1 Byte before) - 127+1 Byte Output data (80+1 Byte before) - 14 Byte Parameter data per IOM (5 Byte before) - 30 signal diagnosis messages (18 before) • Signal parameter - predominant separate parameters for each single signal of IOM (previous partially module global). • HART Variables - HART variables can be mapped to the cyclic data exchange of PROFIBUS DP and transmitted to the PROFIBUS master (PLC/DCS). • Status Fieldstation - A common alarm bit of all alarms of one IS1 fieldstation is mapped to the cyclic data on PROFIBUS DP IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 22 Operating Instructions PROFIBUS DP interface for IS1 3.2.2 System requirements Requirements for use of the Extended Parameter Set of the IS1 Remote I/O System: Hardware requirements: • CPM 9440/12-01-11 (24V Z1 Stahl) as of Revision F • CPM 9440/15-01-11 (24V Z2 Stahl) as of Revision F • CPM 9440/22-01-11 (24V Z1 PNO) all Revisions • CPM 9440/22-01-21 (230V Z1 PNO) all Revisions Software requirements: • IOM Firmware as of Revision 2.00 • GSD file as of Revision V2.00 • without I.S.Wizard ƒ CPM Firmware DPV0 as of Revision V01-30 or ƒ CPM Firmware DPV1 as of Revision V02-30 • with I.S.Wizard V3.x.x and Service Bus ƒ CPM Firmware DPV0 as of Revision V01-32 or ƒ CPM Firmware DPV1 as of Revision V02-32 I M P O R T A N T If using older hardware or firmware versions, GSD files with Version V1.xx (less than V2.00) without extended parameter set must be used with PROFIBUS DP.

IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 45 Operating Instructions PROFIBUS DP interface for IS1 3.6 Signal behaviour in case of errors 3.6.1 Behaviour of the input signals in case of errors If no valid signal value can be formed as a result of a malfunction (short circuit, open circuit, defective subassembly...), a diagnosis information is created and transmitted to the master. Despite the outstanding malfunction, data continues to be transmitted to the master. The behaviour of the signal values transmitted if a malfunction has occurred can be selected separately for every module using parameterisation (see 3.2.2 IOM parameters). Application hint: If the behaviour of input signals in case of error is realized through the IS1 system, this behaviour seen from the application software in the automation system can only be guaranteed with undisturbed communication on PROFIBUS DP. At loss of cyclic communication on PROFIBUS DP additional project specific reactions have to be realized in the application software in the automation system. To guarantee the same behaviour of all input signals in any case of error (even in case of bus failure), we recommend the following procedure: Generate a Status Bit for each input signal in the automaton system: - for DI signals the optional available statusbits of IS1 in the cyclic data of PROFIBUS DP can be used. - for AI signals the ´behaviour in case of error = Alarmcode´ has to be choosen in the parameters of all AI signals (default). In the application software of the automation system the following function has to be used for each AI signal: If SignalValue >= 32512 Or SignalValue <= -32512 then SignalStatusBit = disturbed Else SignalStatusBit = OK End IF The signal behaviour in case of error (freeze, substitute value ...) should now be realized in the automation system In this case the event ´loss of cyclic communication on PROFIBUS´ can be logical wired with the signal status bit whereby the ´signal behaviour in case of error´ is always the same under all error conditions. The additional informations of the diagnosis telegram can be used optionaly to generate message lists for maintenance purposes. IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 46 Operating Instructions PROFIBUS DP interface for IS1 3.6.2 Behaviour of the output signals in case of errors Communication error between the master and IS1 field station: The cyclic data traffic between the class 1 master and the IS1 is checked in the IS1 using response monitoring. Response monitoring in the CPM makes sure that if the master suffers a failure or there is some other communication loss to the master after expiry of the time (T ), the outputs adopt the safe state. WD The T time can be parameterised in the class 1 master within the range 10 ms to 650 seconds and is WD transferred by means of the "SET_PARAMETER" DP service from the master to the CPM. After expiry of T , the cyclic updating of the output modules is stopped by the CPM of the IS1 field station. WD The response monitoring of the slaves can also be deactivated by the master. In this case, the slave cannot recognise a loss of communication to the master. The output signals of the slaves are frozen if updating from the master cannot be performed. Communication error between the CPM and output module: There are Watchdog circuits on the output modules that monitor the data transmission between the CPM and the output modules. If an output module does not receive any valid data for more than T , the subassembly Mod adopts the safety position. T (timeout für output modules) can be parameterised in the DP master within the range 100 ms to 25.5 MOD sec. (default value: 100 ms). Consequently, the safety position of the output modules follows at a delay of T after failure of the S communication to the master where: T = T + T S WD Mod The safety position of the output signals can be parameterised separately for every module (see 3.2.2 IOM parameters). Global Control - Clear Data: Under some conditions the command ´Global Control - Clear Data´ will be transmitted from the DP master. In this case the CPM is putting all output signals to save position even if the data exchange is still working. First after the command ´Global Control - Operate´ from the DP master the transmitted output data is passed through to the output drivers of the output modules. IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 47 Operating Instructions PROFIBUS DP interface for IS1 3.7 Diagnosis data The occurrence of alarm changes is registered to the class 1 master by the IS1 field station in the cyclic data exchange. The class 1 master then demands the diagnosis data from the IS1 field station in an acyclic telegram. In addition to the 6 bytes of standard information complying with the DP standard, the IS1 field station can supply device-related, identifier-related (module-related) and channel-related (signal-related) diagnosis data. Diagnosis data can be displayed in a diagnosis user interface of the master configuration software and can be evaluated via the user program in the automation system. If there are no alarms in a field station, then only the 6 bytes of standard information (byte 0 to byte 5) are transmitted.Only if one or more alarms are present, the additional information (starting from byte 6) is transmitted. This has to be considered at the evaluation of diagnosis data in the AS.

The 3 bytes of a channel-related diagnosis contain the following information: 7 0 Bit no. 1. byte: 1 0 0 0 0 0 0 0 Module / identifier number (slot) 0 - 32 Bit 7, 6 firm at 1 0 (header) 7 0 Bit no. 2. byte: 0 0 0 0 0 0 0 0 Channel / signal number 0 – 15 00 = reserved 01 = input 10 = output 11 = in- / output 7 0 Bit no. rd 3 byte: 0 0 0 0 0 0 0 0 Error type 0 - 31 Channel / signal type 000 = reserved 001 = bit 010 = 2 bits 011 = 4 bits 100 = byte 101 = word 110 = 2 words 111 = reserved IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 53 Operating Instructions PROFIBUS DP interface for IS1 The error type area contains the following information: Error Alarmcode in Meaning type cyclic signal data area Reserved 0 1 Short circuit 7FFF / 8001 Reserved 2 – 5 6 Open circuit 7FFA / 8006 7 Upper limit exceeded 7FF9 8 Lower limit exceeded 8008 Reserved 9 – 15 16 Cold Junction error 8010 Reserved 17 Reserved 18 Reserved 19 Reserved 20 Reserved 21 Reserved 22 Reserved 23 Reserved 24 Reserved 25 Reserved 26 Reserved 27 Reserved 28 Reserved 29 Reserved 30 Reserved 31 Attention The maximum telegram length of the diagnosis telegram is restricted. When using device-related, identification-related and channel-related diagnosis, the maximum transmittable data volume of the diagnosis data can be exceeded if there are many outstanding alarms present at the same time which causes channel-related diagnosis data to be lost. The CPM can transmit a maximum of 21 *1) (19 with CPM Firmware Rev. 01-19 and higher) channel-related diagnosis data. If not all of the channel-related diagnosis data can be transmitted due to a diagnosis buffer overflow, this is displayed in the standardised diagnosis area by the message, “Diagnosis overflow”. Independently of this, the transmission of the device-related and identifier-related diagnoses is always guaranteed. *1) max. 30 channel related diagnosis data using the Extended Parameter Set of IS1 ! IS1 PROFIBUS DP 05/07.23 E - Technical alterations reserved - 54 Operating Instructions PROFIBUS DP interface for IS1 3.8 Online behaviour of the IS1 fieldstation. The IS1 fieldstation is supporting the standard start-up behaviour with a class 1 master (see 2.11 start-up behaviour). Additionaly the following features are supported: 3.8.1 Parameter change. If a I. S.1 fieldstation is in data exchange with a DP master, the telegram ´Set_Prm´ (send parameter) can be transmitted from the master to the fieldstation between the cyclic data telegrams. The fieldstation checks the length of the telegram ´Set_Prm´ and accepts the new parameter data without leaving data exchange if the length of the telegram is OK. With this, online changes of parameter data of the IS1 fieldstation from a PROFIBUS DP (class1 V0) master are possible. If the length of the ´Set_Prm´ telegram is not OK the new parameter data are not accepted. The fieldstation changes to the mode ´wait parameter´ whereby a new start-up of the cyclic communication is forced. 3.8.2 Configuration change. If a IS1 fieldstation is in data exchange with a DP master, the telegram ´Chk _Cfg´ is only accepted from the fieldstation if the configuration data of the fieldstation has not changed. If a telegram ´Chk _Cfg´ with changed konfiguration data is receieved during data exchange, the fieldstation is leaving the data exchange and and goes to the mode ´wait parameter´ whereby a new start-up of the cyclic communication is forced. If a master wants to change the configuration data of the fieldstation or wants to interrupt the data exchange for a defined time, the data exchange should be stopped from the master by sending the telegram ´Set_Prm´ with ´Unlock_Req = TRUE´ (Lock). This will bring the fieldstation to the mode ´wait parameter´. After this the master can do a new start-up with new configuration and parameter data. With the parameter ´ timeout for output modules´ or via response monitoring (see chapter 3.4.2) the output signals of the fieldstation can be freezed during a interruption of the data exchange for a parametrizable time. If the master is coming back to data exchange with the fieldstation before exceeding of this watchdog times, the output signals are not going to the selected save position and are now updated cyclic from the master again. If the master has changed konfiguration data, which has influence to the signal marshalling in the data telegrams, he is responsible for the correct new marshalling inside of the master and the PLC / DCS. During the new start-up the fieldstation is checking the new konfiguration and parameter data individually for each slot (each I/O-module). All modules of the fieldstation where the konfigured module type agree with the existing module type in the fieldstation are updated cyclically after start-up. For modules, which do not agree with the configuration data, alarms are generated. The signals of this modules are not updated and react according the parametrized behaviour in case of error.
