The GE-Emerson IC697BEM711 Series 90-70 Bus Receiver Module permits expansion from the main rack to a maximum of seven additional IC697 PLC racks with up to 50ft (15m) total interconnecting cable. The module occupies a single slot and has two connectors, one for attachment to the upstream or CPU rack and the other for a daisy-chained arrangement to additional expansion racks. The Bus Receiver Module must always be installed in slot 1.
Three green LEDs provide status indication of module status, rack activity status, and presence of the I/O Bus Terminator Plug (IC697ACC702), which is required in the last rack. The Bus Receiver Module supports hold last state operation of the output modules in the event of loss of communications with the CPU. It also permits the isolation and repair of a faulty module within a rack. The module must be configured into the IC697 PLC system using the MS-DOS or Windows programming software configuration function.
