Backplane Bus Communication Velocity & Firmware Execution

The module manages dual backplane architecture interfaces to maintain optimal backplane bus communication velocity across both high-speed RX3i PCI bus structures and legacy Series 90-30 serial buses. System-level firmware flash compatibility enables internal firmware upgrades, while configuration is executed via Machine Edition Logic Developer software (version 5.51 or later).

Frequently Asked Questions

Q: What are the backplane power supply current requirements for the IC695NIU001 module? A: The module draws 1.25 A nominal from the +3.3 VDC rail and 1.0 A nominal from the +5 VDC rail.

Q: Which serial communication protocols are supported by the integrated serial ports? A: The onboard COM ports support SNP, Modbus RTU Slave, Serial I/O, and Modbus RTU Master via application "C" block routines.

Q: Which replacement battery models are compatible with the IC695NIU001 real-time clock? A: Recommended battery options include the RX3i CPU Lithium Smart Battery (IC695ACC302), Series 90-30 Lithium Battery Pack (IC693ACC302), or Smart Coin Cell Battery Pack (IC698ACC701).

Field Installation Guidelines

Baseplate Installation: Turn off system power prior to inserting the module into the designated universal RX3i backplane slot. Press firmly until the rear edge connectors seat completely into the dual backplane bus receptacles.
Battery Connection: Attach the lithium battery pack (IC695ACC302 recommended) to the battery connector housing on the module front panel to maintain real-time clock operation during power loss.
Serial Port Cabling: Connect field communication cables to the COM1/COM2 ports. When using RS-485, ensure proper signal pin assignments and termination resistors are placed across the physical cable ends.
Shield Grounding: Connect serial communication cable drain shields directly to a central enclosure ground point to avoid ground loops and shield high-frequency noise interference.
