1/33 Presentation Modicon M580 automation platform Multi-rack configuration Composition of an expansion backplane configuration M580 CPU supports 4 to 8 local racks (depending upon the CPU performance level), using existing X80 I/O modules and accessories. A Modicon M580 CPU must be installed in the first rack (#0) and this can be a dual bus rack. A Modicon M580 PLC will support up to 7 BMXXBP pppp PV02 or higher backplanes (racks) of 4, 6, 8, or 12 slots. The main backplane (rack #0) will support the CPU. To expand the configuration using additional racks, users must use a bus expansion module ( BMXXBE1000 ) and X-bus cables. The backplane expander will be plugged in the dedicated connector on the right side of the backplane. It will not occupy any module slot. The XBE expansion module will not be hot-swappable in accordance with Modicon X80. Each backplane has to include a power supply module and will support up to 12 modules. An expansion rack can be connected to the main backplane and the X80 drop (EIO). The rack address is assigned as follows: b Each rack will be assigned a physical address using 4 micro switches located in the bus expansion module. b The main rack containing the CPU will be assigned address 0. b The other racks will be assigned addresses 1 to 7. Each rack is equipped with: 1 BMXCPS ppppp power supply 2 BMXXBE1000 rack expansion module. This module, inserted in the right-hand end of the rack (XBE slot) does not occupy rack slots 0011 (4, 6, 8, or 12 slots are still available). 3 The BMXXBE1000 rack expansion modules are connected to each other by X-bus cordsets. 4 Line terminators: Both expansion modules at the ends of the daisy chain must have a line terminator TSXTLYEX on the unused 9-way SUB-D connector. 1 4 4 3 2 Modicon M580 + expansion rack Presentation Modicon M580 automation platform Multi-rack configuration 1 4 4 3 2 Modicon M580 + expansion rack 2 1 3 4 5 6 7 8 9 10 2 1 3 4 5 6 7 8 9 10
