Remanufactured GE-Emerson IC697BEM731 Genius I/O Bus Controller Module

The GE-Emerson IC697BEM731 Genius I/O Bus Controller Module is available as a single channel controller. It occupies a single IC66* PLC slot. The bus controller is configured by the MS-DOS or Windows programming software configurator function. IC66* Input/Output blocks are scanned asynchronously by the bus controller and I/O data is transferred to the CPU once per scan over the backplane of the IC697 PLC rack. 

The bus controller also supports directed communications initiated by a PLC CPU Communication Service Request. In addition, it may be configured to perform global communications. 

Faults reported by the bus controller are managed by the PLC Alarm Processor Function, which time stamps and queues faults in a table. 

For applications requiring peer-to-peer information transfer, the Bus Controller can serve as a communications node linking other devices (Bus Controllers, PCIMs, and other IC66* devices) via the IC66* bus. Such a network can provide communications between multiple PLCs and host computers. These communications include transmitting global data from one CPU to another. The global data area is identified by MS-DOS or Windows configuration. After initialization, the specified data area is transferred between devices automatically and repetitively. 

Messages called Datagrams can be transmitted in response to individual commands in the ladder logic. Datagrams can be sent from one device on the network to another, or broadcast to all devices on the bus. IC66* LAN communications are supported throughout the IC69* PLC family.
