Overview

The IC693DNM200-BD is a DeviceNet Master (Scanner) Module manufactured by GE Fanuc (now under Emerson Automation) for the Series 90-30 PLC and compatible PACSystems RX3i backplanes.

The -BD suffix indicates Revision/Series BD of the hardware module, which includes incremental firmware and component board updates over earlier revisions (e.g., -AA/-AB).

Functional Highlights & Key Notes

Network Master Role:

Acts as the central master on a DeviceNet fieldbus network, enabling automatic I/O data transfer, polling, and explicit messaging between the Series 90-30 CPU and field devices (such as remote I/O blocks, variable frequency drives, motor starters, and sensors).

Configuration Tools:

Configured using GE Machine Edition (PME) or Logicmaster 90 along with the appropriate DeviceNet network configuration utility (e.g., DeviceNet Manager).

Known Operational Parameters:

Ack Timeout Default: The module defaults to a 2-second Ack Timeout parameter. If a slave drops connection, it sends a Duplicate MAC ID check. Setting Ack Timeout = 0 allows the master to continuously attempt reconnection to power-cycled slave units without dropping the slave permanently.

Bus Termination: Requires standard $120\,\Omega$ termination resistors at both physical ends of the main DeviceNet trunk line.
