Operation augmented by the IC697 PLC Alarm Processor function

The IC66* Bus Controller (GBC/NBC) 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 records 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 the MS-DOS or Windows configuration. After initialization, the specified data area is transferred between devices automatically and repetitively.

In addition, 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

IC697BEM731 Installation：

Installation should not be attempted without referring to the applicable PLC Installation Manual.

Make sure the rack power is off.

Install in the rack.

Turn on the power.

The module should power up and blink the top LED for about 5 seconds. When the diagnostics have completed successfully, the top LED on the middle LED is turned ON when a valid configuration for the module has been received from the CPU, and the IC66* I/O bus operation has been verified. The bottom LED is OFF under all conditions.

Removing IC697BEM731：

The instructions below should be followed when removing a module from its slot in a rack.

Grasp the board firmly at the top and bottom of the board cover with your thumbs on the front of the cover and your fingers on the plastic clips on the back of the cover.

Squeeze the rack clips on the back of the cover with your fingers to disengage the clip from the rack rail and pull the board firmly to remove it from the backplane connector.

Slide the board along the card guide and remove it from the rack.
