Backplane Bus Communication Velocity & Network Integration

The central processing unit communicates via the internal backplane bus to control distributed input and output channels. Backplane bus communication velocity guarantees rapid data exchanges across up to 12,000 discrete and 8,000 analog I/O points. Integrated firmware flash compatibility allows program execution from the 256 KB non-volatile memory block, while seamless integration with LAN interface modules, coprocessors, and communication modules expands network density scaling.

Frequently Asked Questions

Q: What memory allocation is available on the IC697CPU781 module for program and configuration storage?

A: The module provides 512 KB of volatile memory for user data execution and 256 KB of non-volatile flash memory for non-volatile program storage.

Q: What maximum I/O capacities can be addressed by this central processing unit?

A: The processor addresses up to 12,000 discrete I/O points and up to 8,000 analog I/O points across the backplane chassis configuration.

Q: How fast is the logic execution speed of the onboard microprocessor?

A: The 16 MHz microprocessor executes Boolean functions at a speed of 0.4 microseconds per instruction.

Field Installation Guidelines

Baseplate Insertion: Ensure backplane power is fully switched off prior to mounting the CPU module into the primary slot of the Series 90-70 rack to avoid connector damage.
Cabinet Thermal Protection: Maintain clean airflow pathways above and below the module rack to preserve the operating temperature range between 0 and 60 deg C.
Communication Interface Cable Grounding: Ground all shielded cables connected to option modules or LAN interfaces directly to the cabinet ground bar to prevent noise disruption.
Storage Environment Handling: Store spare modules in environments maintained within -40 to 85 deg C to prevent memory substrate degradation.
