VMIVME-1182 is a 64-channel optically isolated digital input board that can detect Changes of State (COS) on any of the 64 inputs. This COS data can be used in Sequence-of-Events (SOE) acquisition. The board provides pulse accumulation data, time tag data, and programmable debounce for each input. A variety of interrupt options are available. Figure 1 on page 14 is a block diagram of the VMIVME-1182. The VMIVME-1182 features are outlined below. • 64 optically isolated inputs Multiple-functions available per channel: – SOE reporting – Pulse accumulation reporting – Time tag reporting – Programmable debounce times Available in 5 to 250VDC or 4 to 240VAC options Available in contact sensing or voltage sensing options 1500VDC or 1100VRMS channel-to-channe l and channel-to-VME isolation (1 minute) Pulse accumulation for up to 65,535 pulses per channel SOE monitoring on a channel-by-channel basis Debounce time software controll ed on a channel-by-channel basis COS monitoring software controll ed on a channel-by-channel basis A24/A16 addressing capability Supervisory bus access, nonprivileged bus access, or both Release-On-Acknowledge (ROAK) interrupts on all VME levels 11 VMIVME-1182 64-Channel Isolated Digital Input Board with Multifunctional Intelligent Controller Functional Description The VMIVME-1182 provides COS detection on all of its 64 inputs. Each input may be software controlled to detect rising edges, falling edges, or both rising and falling edges, or it may be software controlled to ignore all changes for a given channel. In addition to COS detection, a variety of reporting and interrupt capabilities are available. Each COS event may be stored in an SOE buffer where it is time tagged with a relative timer value of up to 65,535ms. The timer may be reset from the VME when desired. Each COS event is counted in Pulse Accumulation Count registers, which record the number of events per channel. VME interrupts may be issued on any level (software selectable), and a single byte vector is placed on the bus during the acknowledge cycle. The interrupt is cleared during the acknowledge (ROAK). Addressing is jumper selected and supports both A24 and A16 address space. Address modifiers are jumper-selected and are decoded to support nonprivileged, supervisory, or both nonprivileged and supervisory access.

The following paragraphs summarize the major board functions, and the remainder of the Theory of Operation describes each function individually. The information in this section is supplemented by programming details in Chapter 3 “Programming”. Internal Functional Organization The VMIVME-1182 is a 64-channel optically isolated digital input board that provides the user with a continuous update of the state of the 64 inputs. The user may elect to interrupt the host upon selected change-of-state events. COS data and time tag information is stored in memory (SOE monitoring) for later processing. The SOE memory is allocated into two buffers which store the COS data with a sequential time tag for each event in the order that they occurred. The host can process the SOE buffer without losing any COS data from the inputs. The VMIVME-1182 provides a Pulse Accumulation Count register for each channel. When enabled, these registers each store a count representing the number of times a COS has occurred on its associated input. 17 1 VMIVME-1182 64-Channel Isolated Digital Input Board with Multifunctional Intelligent Controller Inputs can be programmed individually for a debounce time from 1.25ms to 1.024s. The board design can be logically divided into functional blocks which describe the following principal hardware functions: Field Inputs Input Data Processing by the Digital Signal Processor (DSP) EPROM VME Interface Control Logic Bus Interrupter Watchdog Timer Self-Test Power Requirements 18 Field Inputs 1 Field Inputs The field inputs consist of 64 optically isolated inputs. Input options may be ordered to support either contact sensing or voltage sensing in a variety of AC or DC voltage ranges. The inputs are provided through connectors P3 and P4. Chapter 2 provides detailed information about both of these connectors. Voltage Sensing The Voltage Sensing option detects the presence or absence of a voltage at the inputs. Figure 1-1 below shows typical voltage sensing input circuitry. USER-SUPPLIED PX-AXX VOLTAGE SOURCE HIGH OPTICAL ISOLATOR CH.XX USER-SUPPLIED PX-CXX VOLTAGE RETURN LOW Figure 1-1 Voltage Sensing Input Circuit Contact Sensing The Contact Sensing option detects the presence or absence of a closed contact set across the inputs. Figure 1-2 below shows typical Contact Sensing Input circuitry. The external “wetting” voltage can be applied at the P2 connector on a byte level or can be applied to P3 at channel 32. This is described in detail in Chapter 2.

In default mode, the inputs are stored every millisecond and can be accessed by the user at any time. The programmable features are executed through an onboard DSP chip and include: Debounce time for each input Pulse accumulation for each input COS definition/selection for each input Time tag clock Sequence-of-Event monitoring Each feature is described in the following paragraphs. Debounce Time The VMIVME-1182 provides 64 registers which contain the desired debounce time for each input. The debounce time ranges from 1.25ms (default) to 1.024s. See Chapter 3 for more information on selecting debounce times. The debounce algorithm is implemented by the DSP microcontroller. Through the optical isolator, all 64 field inputs are clocked into registers during the DSP time interrupt service routine. The DSP processes this data using an algorithm which determines a true high or low state. A different algorithm may be used by setting a bit in the Debounce/Select Register (see Chapter 3). This algorithm accepts inputs from AC signal sources. The rising edge period is determined by the Debounce/Select time provided by the user. The falling edge period requires the DSP to detect a low at four times the debounce time in milliseconds. This ratio, the AC Ratio, is defined in the Chapter 3 “Programming”. Pulse Accumulation Each channel has an associated PAC register. The count represents 0 to 65,535 pulses. A pulse is defined as either a state change from zero (0) to one (1) or a state change from one (1) to zero (0), but not both. If the PAC Interrupt Enabled bit is activated, the PAC register interrupts the host when it rolls over to zero (0). COS Definition Each channel can be programmed to detect rising edge (low to high) only, falling edge (high to low) only, both edges, or no detection (COS disabled). Interrupts can be issued when any input meets the programmable COS selection. A detailed description of this function is found in Chapter 3. 20 Input Data Processing 1 Time Tag Clock The Time Tag register is updated every millisecond. The user may reset or preset this data at any time. The Time Tag feature is provided by the DSP Timer Interrupt Logic and microcontroller. The microcontroller is interrupted every millisecond. During the interrupt service routine, the field inputs are stored and a frame flag is updated. A frame is the period in which all 64 inputs have been processed. Every frame, the DSP updates the Time Tag data. Each bit of the count in the Time Tag register represents 1ms. Sequence of Event Depending on COS select options, each COS can be time tagged in the SOE buffer. The SOE buffer collects the channel ID and the time in which the state changed. This buffer can contain 3072 events. When the host is accessing the SOE buffer, the VMIVME-1182 continues to monitor the inputs and stores events in a mirrored SOE buffer. The additional buffer also provides 3072 events of storage, allowing the user sufficient time to process the SOE data without losing event data. The SOE logic can provide an interrupt to the host at the end-of-buffer or at a count provided by the user. The SOE buffer arbitration is controlled by software. To read the data in the SOE buffer, the host first writes to the SOE Request register. A write to this register interrupts the DSP code and switches the pointer in the DSP to the second SOE buffer. The VME then has access to the first SOE buffer while the DSP continues its updates to a second SOE buffer. This method allows the DSP to always have access to one of the SOE buffers in order to prevent data loss. NOTE: The DSP will auto wrap the buffer and begin writing over old data whenever the buffer reaches the physical end of the buffer. The SOE count rolls over from 3072 to zero (0) and continues counting. The host must process the data from the primary buffer before the DSP reaches the physical end of the data buffer or data can be lost. interrupts are provided (SOE maximum count) to alert the host that data needs to be processed. The SOE count is valid for whichever SOE buffer the DSP is currently updating. Once the buffer is requested, the SOE count is written to the SOE index and then reset to zero (0). EPROM DSP firmware is stored in the EPROM and is loaded into the DSP during power up or after a reset to the DSP. The DSP can be reset by the VME system reset or by the watchdog timer circuitry. 21 1 VMIVME-1182 64-Channel Isolated Digital Input Board with Multifunctional Intelligent Controller VME Interface The VME interface consists of: Address decoding for the A24/A16 address space Address modifier decoding for su pervisory/nonprivileged accesses D16/D8 data transfers ROAK interrupter circuitry Two SOE buffers Control logic memory Control Logic The Control Logic offset address begins at $000. The Board ID register contains an ID code which indicates the VMIVME-1182 is present. The Control and Status register provides control of the front panel LED, the Test Mode Disable, and various interrupt enables. It also provides various flags, including a Self-Test complete flag. The Self-Test Results register provides pass/fail status of the VMIVME-1182 integrity tests. The Interrupt Vector register provides programmable level and vector data. Debounced input data is provided in four words, each bit representing a channel. Change of State registers are provided in four words, each bit representing a channel. Pulse Accumulation Interrupt registers are provided in four words, each bit representing a channel. Each channel has an associated Debounce/Select register and Pulse Accumulation Count register. A Time Tag register is provided and is updated every millisecond. Three registers are provided to support SOE buffer function: the Maximum SOE Count, the SOE Count, and the SOE Index. When used in conjunction with the Debounce/Select registers, the AC Input register provides debounce with AC input. 22 Bus Interrupter 1 Bus Interrupter A Bus Interrupter provides access to the VME interrupt structure. An interrupt can be issued on any level (software selectable), and a single byte vector is placed on the bus when acknowledged. Any of the following conditions can initiate the interrupt: COS on any of the 64 channels Time Tag rollover Pulse Accumulation rollover on any of the 64 channels SOE, End-of-Buffer, First Word Received SOE buffer count equal to programmable maximum count provided by the user Each of these interrupt conditions may be enabled or disabled by the host. A global disable occurs if the interrupt level is set to zero (0). There is one ROAK interrupt for the VMIVME-1182 board. Details of the interrupter capabilities are described in Chapter 3 “Programming”. 23 1 VMIVME-1182 64-Channel Isolated Digital Input Board with Multifunctional Intelligent Controller Watchdog Timer The VMIVME-1182 monitors the health of the DSP and resets it if necessary. The DSP must write to a specified address every millisecond or the watchdog timer will issue a reset to the DSP. A reset to the DSP results in reloading the EPROM data and reinitializing the default conditions. The VMIVME-1182 is off-line at this time. This circuitry also monitors the general integrity of the +5V on the VME and issues a reset to the DSP if it falls below +4.5V. 24 Self-Test 1 Self-Test The VMIVME-1182 performs Self-Test functions when one of the following conditions occur: VME SYSRESET activated Watchdog timer invokes a reset to the DSP Test Mode bit in CSR activated The DSP performs the Self-Test of the VMIVME-1182. Control memory and both SOE memory buffers are tested, and the results stored in the Self-Test Status register located in control memory. The Self-Test mode is an integrity test of the DSP and the memory. The field input connectors to the digital registers are not tested on-board. The VME-to-VMIVME-1182 memory is not tested in Self-Test mode. System test software is responsible for determining these functions and for turning the front panel LED off when the system has determined that the VMIVME-1182 has passed. 25 1 VMIVME-1182 64-Channel Isolated Digital Input Board with Multifunctional Intelligent Controller Power Requirements The power requirement for the VMIVME-1182 is 2A (typical) at 5V plus any power dissipated in pull-up resistors. 26 CHAPTER 2 Configuration and Installation Contents Unpacking Procedures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 28 Physical Installation. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 29 Operational Configuration . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30 Field Input Configurations . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 34 System Connections. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 38 Introduction This chapter describes the installation and configuration of the board.

The four, user-defined jumper fields for field inputs are described in the following sections. The connector pinout descriptions are shown in Figure 2-9 on page 39 and Figure 2-10 on page 40. Voltage Sensing The user input connection circuit for voltage sensing is shown in Figure 2-5 below. Jumpers E1 and E4 are installed for this configuration. Jumpers E2 and E5 are omitted (see Table 2-2 below). This disables the wetting voltage input at P3 and allows channel 32 to be used as an input channel.

The wetting voltage may be applied for all channels through P3 instead of P2. Channel 32 cannot be used as a channel input and must be configured (by jumpers) to accept external wetting voltage. See Table 2-6 on page 37 for a description. The wetting voltage input of all channels are tied together with the installation of E5. E4 is used as a carrier for the jumper. Reference ground may be output on P3 by installation of E2. The user is required to move the jumpers to the proper location. (See Table 2-5.) CAUTION: Installation of jumper E1 while also using external voltages on the P2 connector may result in physical damage to the circuit board and or the external power supply.

After initial power up, system reset, or watchdog timer reset, the following conditions are initialized: Fail LED is ON All interrupts are disabled All flags are cleared Test mode enabled IVR register is cleared COS registers are cleared PAI registers are cleared DSR registers are cleared PAC registers are cleared Time tag clock set to zero (0) and stopped SOE maximum count is cleared SOE count is cleared SOE buffers contain test data, if self-tes t fails. Otherwise, the buffers are cleared. Self-Test Complete bit is set in the CSR If the initial conditions meet default requirements, then the user writes to the CSR to disable test mode and turn off the Fail LED. The user may then begin reading the input data registers which are updated with field data every millisecond. Table 3-1 on page 42 is the address map for the VMIVME-1182. All addresses shown are relative to the board’s base address. NOTE: To be consistent with conventional VME development system nomenclature, hexadecimal numbers in this document are designated with a "$" prefix unless otherwise indicated. decimal numbers are presented without a prefix. 41 3 VMIVME-1182 64-Channel Isolated Digital Input Board with Multifunctional Intelligent Controller Table 3-1 VMIVME-1182 Memory Map Relative Address Description Desig Read/Write $000 Board ID Register BID Read $002 Control and Status Register CSR Read/Write $004 Self-Test Results Register STR Read/Write $006 Interrupt Vector Register IVR Read/Write $008 Debounce Input Data for Channels 63-48 IDR 0 Read/Write $00A Debounce Input Data for Channels 47-32 IDR 1 Read/Write $00C Debounce Input Data for Channels 31-16 IDR 2 Read/Write $00E Debounce Input Data for Channels 15-00 IDR 3 Read/Write $010 Change of State for Channels 63-48 COS 0 Read/Write $012 Change of State for Channels 47-32 COS 1 Read/Write $014 Change of State for Channels 31-16 COS 2 Read/Write $016 Change of State for Channels 15-00 COS 3 Read/Write $018 Pulse Accumulation Interrupt Chan 63-48 PAI 0 Read/Write $01A Pulse Accumulation Interrupt Chan 47-32 PAI 1 Read/Write $01C Pulse Accumulation Interrupt Chan 31-16 PAI 2 Read/Write $01E Pulse Accumulation Interrupt Chan 15-00 PAI 3 Read/Write $020 - $09E Debounce/Select Register (0-63) DSR Read/Write $0A0 - $11E Pulse Accumulation Count Register (0-63) PAC Read/Write $120 Time Tag Register Read/Write $122 Maximum SOE Count Register Read/Write $124 SOE Count Register Read/Write $126 SOE Index Register Read/Write $128 Reserved (Note 1) Read/Write $12A AC Input Register (default = 5) Read/Write $12C Reserved (Note 1) Read $12E Revision Level Register Read $130 - $7FE Reserved (Note 1) $800 Force LED Register Write $802 SOE Request Register Write $804 - $9FE Reserved (Note 1) $1000 - $3FFE Sequence-of-Events Buffer Register Read/Write Note 1: Must remain data = 0 42 Board ID Register (BID) 3 Board ID Register (BID) The BID register is a 16-bit read-only register. Its data is fixed at $3800. Table 3-2 shows the bit map for this register.

Table 3-3 below shows the bit map for this register. Table 3-3 Control and Status Register Bit Map Relative Address $002 CSR (read/write) Bit 15 Bit 14 Bit 13 Bit 12 Bit 11 Bit 10 Bit 09 Bit 08 Fail_LED Test Mode COS Reset COS INT DIS SOE WD INT SOE CNT PAC INT EN TAG INT EN EN INT EN Bit 07 Bit 06 Bit 05 Bit 04 Bit 03 Bit 02 Bit 01 Bit 00 SOE WD FL SOE CNT FL PAC FL TAG FL BUFF END Reserved Self-Test FL Complete Control and Status Register Bit Definitions Bit 15: Fail_LED - Controls the Fail LED. Writing a zero (0) to this bit turns the Fail LED ON; writing a one (1) turns it OFF. The default condition is zero (0). Bit 14: Test Mode - Controls the Test Mode. Writing a zero (0) to this bit initiates Test Mode. The default condition is zero (0). Test mode is enabled at power up, and the results are stored in the Self-Test Results register. To initiate test mode, the bit must be disabled by writing the bit to one (1) and then enabled by writing the bit to zero (0). Bit 13: COS Reset - Clears the COS registers. Writing a one (1) to this bit clears all bits in the COS registers. After the COS registers are cleared, this bit is set to zero (0) by the microcontroller. After power up or reset, this bit is zero (0). Bit 12: COS INT DIS - Controls the COS interrupts. Writing a one (1) to this bit disables the COS interrupts but allows COS data to be stored in the SOE buffer. The default condition is zero (0), allowing interrupts for any input meeting the requirements of its DSR. Bit 11: SOE WD INT EN - Controls the SOE First Word interrupt. Writing a one (1) to this bit causes the board to interrupt the host whenever the first COS is received. The default condition is zero (0) which prevents an interrupt on this condition. Bit 10: SOE CNT INT EN - Controls the SOE Buffer Count interrupt. Writing a one (1) to this bit causes the board to interrupt the host whenever the SOE count reaches the programmed value in the SOE Maximum Count register or when it reaches the physical end of memory. The default condition is zero (0) which prevents an interrupt on this condition. 44 Control and Status Register (CSR) 3 Control and Status Register Bit Definitions (Continued) Bit 09: PAC INT EN - Controls the Pulse Accumulation Count Interrupt. Writing a one (1) to this bit causes the board to interrupt the host whenever any of the 64 PAC registers rolls over from a maximum count to zero (0) and sets the corresponding bit in the PAI registers. The default condition is zero (0) which prevents an interrupt on this condition. Bit 08: TAG INT EN - Controls the Time Tag Interrupt. Writing a one (1) to this bit causes the board to interrupt the host whenever the Time Tag Counter rolls over from maximum count to zero (0). The default condition is zero (0) which prohibits an interrupt on this condition. Bit 07: SOE WD FL - Set to one (1) whenever the first COS has been received and the SOE count equals one (1). The user must clear this bit by setting it to zero (0). This bit is active even if interrupts are disabled. The default condition is zero (0). Bit 06: SOE CNT FL - Set to one (1) whenever the SOE count has reached the preprogrammed value stored in the Maximum SOE Count register. The user must clear this bit by setting it to zero (0). This bit is active even if interrupts are disabled. The default condition is zero (0). Bit 05: PAC FL - Set to one (1) whenever any of the PAC registers ($0A0 through $11E) has rolled over. The user must clear this bit by setting it to zero (0). This bit is active even if interrupts are disabled. The corresponding bit (Channel ID) is set in the PAI register. The default condition is zero (0). Bit 04: TAG FL - Set to one (1) whenever a Time Tag overflow has occurred. The user must clear this bit by setting it to zero (0). This bit is active even if interrupts are disabled. The default condition is zero (0). Bit 03: BUFF END FL - Set to one (1) whenever the physical end of memory has been reached. The user must clear this bit by setting it to zero (0). The default condition is zero (0). Bit 02 and 01: Reserved - The data must remain zero (0). Bit 00: Self-Test Complete - Set to one (1) whenever the self-test is complete. This bit is not cleared (set to zero (0)) when test mode is disabled. 45 3 VMIVME-1182 64-Channel Isolated Digital Input Board with Multifunctional Intelligent Controller Self-Test Results Register (STR) The VMIVME-1182 performs Self-Test functions when one of the following conditions occur: VME SYSRESET activated Watchdog timer invokes a reset to the DSP Test Mode bit in CSR activated (The bit must be deactivated before it can be reactivated.) The Self-Test of the VMIVME-1182 is performed by the DSP. Control memory and both SOE memory buffers are tested and the results stored in the Self-Test Status register located in control memory. The Self-Test mode is an integrity test of the DSP and the memory. The microcontroller sets the complete bit in the CSR but the user is responsible for clearing it and the STR register. Table 3-4 is the bit map for this register. The STR contains a data pattern of $0CBA whenever the self-test is completed and passed.

This test is performed by the microcontroller by writing address equal data to the Control Register RAM. The data is then read and compared for accurate results. The control RAM is cleared after the results are posted. Bits 07 through 04: Set to $B whenever Buffer B has been tested and passed. This test is performed by the microcontroller by writing an incremental (by 1) pattern from 0 through $17FF to the SOE buffer B RAM. The data is then read and compared for accurate results. Bits 03 through 00: Set to $A whenever Buffer A has been tested and passed. This test is performed by the microcontroller by switching the buffer to A and writing a decremental pattern from $17FF through 0 to the SOE buffer A RAM. The data is then read and compared for accurate results. NOTE: If self-test fails, then SOE buffer A and SOE buffer B test patterns are not cleared at the time the test complete bit of the CSR is set. If self-test passes, then the buffers are cleared before the test complete bit of the CSR is set. 46 Interrupt Vector Register (IVR) 3 Interrupt Vector Register (IVR) The IVR is a 16-bit register used to enable any interrupts that may be set up in the CSR. Table 3-5 shows the bit map of the IVR.

These registers are updated upon every change of state (if enabled). If the bit is a one (1), the input has had a change of state. These bits can be cleared by writing zero (0) to the registers or by writing a one (1) to bit 13 of the CSR. Bit 13 of the CSR is cleared when the COS registers are cleared.

The Time Tag counter is a free-running counter which can be preset during non-test mode. At maximum count, the board sets a flag in the CSR and issues an interrupt to the host if the Time Tag Rollover interrupt is enabled in the CSR. Table 3-14 shows the bit map of the Time Tag register. The bit weight is 1.25ms.

This register enables the user to program the maximum count of events before an SOE buffer count interrupt occurs. If the maximum count is reached, the board sets a flag in the CSR and interrupts the host if the SOE count interrupt is enabled in the CSR. See Table 3-15 for bit definitions. The Maximum SOE Count should be set for $C00 or less. $C00 represents the last SOE event that can be stored. Any further events overwrite the beginning of the buffer resulting in a loss of data.

The register is initialized at system reset. When an SOE Request is received, the count is written to the SOE index register and then reset. Table 3-16 shows the SOE Count register bit map.

Adjust the debounce time and change-of-state parameters as described in Section "Debounce/Select Registers (DSR)". AC inputs are detected as pulse trains with assumed duty cycles of approximately 35 percent. Consequently, the delay time for a LOW-to-HIGH transition is determined by input sensitivity and may vary as much as 50 percent from the selected debounce time. Delay times for HIGH-to-LOW transitions, however, are not affected by input sensitivity and should agree closely with selected debounce times. Debounce times for AC inputs should be selected to include at least five complete cycles of the AC input waveform. For example, debounce times for 50Hz inputs (period equals 20ms) should not be less than 100ms. 57 3 VMIVME-1182 64-Channel Isolated Digital Input Board with Multifunctional Intelligent Controller Revision Level Register The value in this register corresponds to the part description in the assembly drawing for the EPROM on the VMIVME-1182. 58 Force LED Register 3 Force LED Register The Force LED is a write-only (data = don't care) register which forces the front panel LED on. If Force LED is activated, the CSR bit 15 is ignored, and the LED can only be turned off by a VME system reset. See Table 3-18 for the Force LED bit map.

A write to this register allows the user access to the SOE data, copies the SOE count to the SOE Index register, and resets the SOE count. Table 3-19 shows the bit map of the SOE Request register.

If the user issues a SOE Request, the board may continue to store up to 3072 more events while the user is processing the present buffer. CAUTION: The DSP will auto wrap the buffer and begin writing over old data whenever the buffer reaches the physical end of the buffer. The SOE count rolls over from 3072 to zero (0) and continues counting. The host must process the data from the primary buffer before the DSP reaches the physical end of the data buffer or data can be lost. Interrupts are provided (SOE maximum count) to alert the host that data needs to be processed. The event data stored in the SOE buffer consists of two words. Word 1 is a 16-bit time stamp as read from the Time Tag register when the COS occurred. The Channel ID is located in word 2 in the lower byte (bits 7 through 0). If the state changed from a zero (0) to a one (1), bit 8 of word 2 is set to a one (1). If the state changed from a one (1) to a zero (0), bit 8 of word 2 is set to a zero (0).
