Backplane Bus Communication Velocity & Firmware Processing
The module executes discrete ladder logic routines at 0.4 us per Boolean function using an integrated 12 MHz Intel 80C186 microprocessor with native floating-point math support. Backplane bus communication velocity allows the unit to scan up to 2K discrete and 8K analog I/O points across the rack assembly without cycle delays. System parameter options configure entirely through software tools, eliminating onboard physical DIP switches or manual jumpers, while firmware flash compatibility ensures synchronized operational execution across Option Modules and Genius I/O networks.
Frequently Asked Questions
Q: What power bus requirements does the IC697CPU772 demand from the backplane?
A: The module draws a nominal current of 1.2 A directly from the regulated +5 VDC backplane power bus.
Q: Is the CPU module restricted to a specific physical position within the rack assembly?
A: Yes, the IC697CPU772 must install exclusively into Slot 1 of the primary Series 90-70 rack to properly drive the backplane bus interface.
Q: How is volatile memory retained during a main power drop?
A: Program routines and configuration data depend on a battery-backed lithium cell maintained on the CPU board or expansion RAM module.
Field Installation Guidelines
Always isolate primary AC supply power to the rack rack enclosure before inserting or removing the module. Align the PCB edge contacts precisely with the backplane connector in Slot 1 and push firmly until the unit seats flush with the rail. Secure the top and bottom mounting screws to establish chassis ground continuity and prevent vibration dislodgement. Use grounded static-dissipative wrist straps during installation, and verify that the lithium battery is connected before clearing system power to prevent volatile RAM corruption.
