Product Overview

The 100% Brand New GE IC694DNM200 operates as a DeviceNet Master module for PACSystems RX3i and Series 90-30 PLCs. It connects the CPU to a DeviceNet network and manages data exchange with up to 63 slave devices (drives, I/O blocks, sensors). The module occupies a single slot in the main CPU rack and draws power directly from the 5 VDC backplane.

Engineering Advantages

•  

  Legacy Network Integration: The module interfaces RX3i CPUs with existing DeviceNet infrastructures. Plants retain installed DeviceNet I/O blocks and smart devices during a control system upgrade without replacing field wiring.

   

•  

  Flexible Data Handling: It supports multiple connection triggers like Change of State (COS) and Polled modes. Engineers optimize bandwidth by configuring high-priority devices to report only on state changes rather than fixed intervals.

   

•  

  Direct Firmware Updates: The front-panel RS-232 port connects to a PC for firmware upgrades or diagnostics. Technicians update the module without removing it from the rack or using the PLC programming software.

   

•  

  Diagnostic Visibility: Three front LEDs (Net Power, Mod Status, Net Status) display bus health, module faults, and network power status. This allows rapid identification of cabling faults or slave communication errors on the shop floor.

   

FAQs

•  

  Can I install this module in an expansion rack?

  No. The IC694DNM200 must reside in the main CPU rack (Rack 0). It does not operate in expansion or remote I/O racks.

   

•  

  Does it require an external 24V power supply for the DeviceNet bus?

  Yes. While the module logic runs on 5V backplane power, the DeviceNet trunk line requires an external 24V DC supply (typically sourced via the DeviceNet connector or a separate power tap).

   

•  

  Is the IC694DNM200 hot-swappable?

  No. You must power down the rack before inserting or removing the module to prevent backplane damage.

   

•  

  What software configures the DeviceNet slaves?

  Configuration requires Proficy Machine Edition (PME) version 3.0 SP1 or later. It does not support VersaPro or Logicmaster software.
