Backplane Bus Communication Velocity and System Integration

The IC697CPU771 executes user logic and manages system backplane communication across standard VME C.1 format backplane baseplates (IC697CHS750, 782, 783, 790, 791). Internal bus arbitration logic optimizes backplane bus communication velocity during real-time data exchanges with connected LAN interface modules, coprocessors, bus controllers, and discrete or analog I/O cards.

Firmware flash compatibility supports system logic execution generated via Logicmaster 90-70, VersaPro Professional Edition, or Proficy Machine Edition Logic Developer. Direct hardware memory scaling accommodates up to 512 KB of expansion RAM, while hardware floating-point math support enables execution of dynamic process algorithms.

Frequently Asked Questions

Q: Where must the IC697CPU771 CPU module be physically installed within a Series 90-70 system rack?

A: The IC697CPU771 must be mounted in Slot 1 of Rack 0 in the Series 90-70 chassis.

Q: How is RAM memory maintained on the IC697CPU771 during system power loss?

A: Program logic and registers are retained in volatile RAM via an IC697ACC701 lithium battery backup circuit connected to the module assembly.

Q: Which communication interface is available directly on the IC697CPU771 module?

A: The CPU module features a single built-in RS485 serial port for direct programming, diagnostic interface, and serial device communications.

Field Installation Guidelines

Always verify that main system power is completely disconnected before inserting or removing the CPU module from Slot 1 of Rack 0.
Align the module card edges precisely with the rack guides and slide firmly into the VME backplane socket until the locking tabs engage.
Connect a fresh IC697ACC701 lithium battery to the memory retention circuit before system power-down to prevent logic memory loss.
Maintain effective protective earth grounding between the Series 90-70 rack frame and the enclosure DIN/chassis grounding point.
Verify proper panel ventilation around the rack assembly to keep operating temperatures within the specified limits of 0 to 60 deg C.
