Leave 12 mm of free space on the right side of the rack to insure a free flow of air for cooling. Leave 35 mm in front of the module for the local bus connector and terminator. Grounding of the The BMX XBE 1000 module is equipped with ground connection contacts (see Rack Extender Grounding of Installed Modules, p. 29).

Note: The cumulative length of all the BMX XBC •••K or TSX CBY •••K cables used in a PLC station must not exceed 30 meters. Extension Cable Racks are connected by means of BMX XBC K or TSX CBY K extension cables which are connected to the 9-pin SUB-D connectors situated on the BMX XBE 1000 module of each main and extension rack. Line Terminators The BMX XBE 1000 modules of the two racks situated at the start and at the end of the chain must always be fitted with TSX TLY EX line terminators on the unused 9- pin SUB-D connectors. Line terminators are labeled A/ or /B. A PLC station that uses extension modules must use one line terminator labeled A/ and one labeled /B. For example, if the extension module in the first rack of the chain contains a terminator labeled A/, then the extension module in the last rack must contain a terminator labeled /B 200 35012676.02 07/2008 BMX XBE 1000 rack extender module Positioning of Positioning on a PLC station containing several BMX XBP extension racks: Line Terminators BMX XBE 1000 on a TSX TLYEX Modicon M340 Station BMX XBP xxxx TSXTLYEX TSXTLYEX TSXTLYEX TSXTLYEX A A B B BMX XBP xxxx BMX XBC xxxK / TSX CBY xxxK TSXTLYEX TSXTLYEX TSXTLYEX TSXTLYEX A A B B BMX XBP xxxx TSX TLYEX Positioning on a PLC station containing a single BMX XBE 1000 extension module: TSXTLYEX TSXTLYEX TSXTLYEX TSXTLYEX BMX XBE 1000 A A B B TSX TLYEX BMX XBP xxxx TSX TLYEX TSXTLYEX TSXTLYEX TSXTLYEX TSXTLYEX A A B B 35012676.02 07/2008 201 BMX XBE 1000 rack extender module Rack extender Module Configuration At a Glance The rack extender modules are configured using microswitches on the side of the modules. The configuration of the module must be done before mounting the module on the rack. PLC station rack addressing depends on the number of racks used: z PLC station built with a single rack, z PLC station built with extension racks. Station built with If the PLC station is built with a single rack, the rack address is implicit and has a a single rack value of 0. If a rack extender module is installed in this rack, line terminators must be connected to the local bus connectors, and the microswitches on the side of the module must be configured for rack 0 (refer to the table of rack addresses in the next paragraph). 202 35012676.02 07/2008 BMX XBE 1000 rack extender module Station built with For a PLC station built with extension racks, an address must be assigned for each extension racks station rack. This address is coded using 3 microswitches on the side of the module. Microswitches 1 to 3 are used to code the rack address on the local bus (address 0 to 3). Diagram showing the microswitches: Table of rack addresses: Switch Rack Address 012 3 1 OFF OFF OFF OFF 2OFF OFF ON ON 3OFF ON OFF ON 4 Not applicable Note: On delivery, all the microswitches are delivered in the OFF position (address 0). 35012676.02 07/2008 203 BMX XBE 1000 rack extender module Assigning Address 0: this address is always assigned to the rack which supports the addresses to BMX P34 1000/2000/2010/2020/2030 processor. different racks This rack can be located in any position in the chain. If two or more racks are configured with address 0, only the rack supporting the processor will function correctly. Addresses 1 to 3: can be assigned in any order to all the other extension racks in the station. If two or more racks are configured with the same rack address (other than 0), the behavior depends on the position of the modules in those racks: z If each module position is only used once, the modules will function correctly. z If modules are mounted in the same position on two or more racks, those racks will not function, the access to them will be blocked. 204 35012676.02 07/2008 BMX XBE 1000 rack extender module Rack Extender Module Diagnostics BMX XBE 1000 The BMX XBE 1000 module display panel, located on the front of the module, is Module LEDs used for diagnostics.

Module The rules for installing modules on a rack are as follows: Installation z The power supply module must always be installed in the slot marked CPS. Rules z The processor must be installed in the slot marked 00. z The I/O and application-specific modules are installed in slots marked 01 to n (n varies according to the rack, see below table). z The extension module is always installed in the slot marked XBE. WARNING UNEXPECTED EQUIPMENT OPERATION Check that the processor module is installed in slot 00 before powering up the system. Otherwise unexpected equipment operation can result. Failure to follow these instructions can result in death, serious injury, or equipment damage.
