Firmware Flash Compatibility and Redundant Execution

The hardware utilizes a 16 MHz internal clock structure to manage high-speed data exchanges across the VME backplane. In redundant configurations, firmware flash compatibility between the primary and secondary units is required to maintain the 20 milliseconds scan extension limit. A firmware mismatch halts execution and prevents the one-scan bumpless transfer sequence when a transition from RUN to STOP mode occurs.

Frequently Asked Questions

Q: What is the exact operational current load drawn by the module from the backplane?

A: The module draws a constant load of 1.6 Amps from the 5 VDC backplane power rail. Power supply sizing calculations for rack 0 must account for this baseline draw alongside any adjacent bus transmitter or redundancy communication modules.

Q: How is the non-volatile memory protected during an extended power outage?

A: The system memory retains data for up to six months using the IC697ACC701 lithium battery connected to the module front face. If the battery voltage drops below the critical threshold, the "Module OK" LED status transitions to indicate a memory backup fault.

Field Installation Guidelines

Slot Restrictions: The module must be installed exclusively in slot 1 of rack 0 within the Series 90-70 chassis to establish mastership over the VME backplane standard C.1 communications.
Redundancy Communication Link: When deploying a hot-standby pair, verify that the dedicated bus transmitter modules and redundancy cards are fully seated and anchored before powering up either CPU node.
Battery Connection: Ensure the IC697ACC701 battery lead is securely plugged into the internal board connector prior to sliding the chassis into the frame to avoid memory parity errors on initial boot.
