GE Fanuc Series 90-30 DeviceNet Master Module IC693DNM200

Product Overview

The GE Fanuc IC693DNM200 serves as the primary IC693DNM200 DeviceNet Master Module utilized to execute high-speed industrial network communication across Series 90-30 platforms. This communication interface enables a Series 90-30 central processing unit to command, configure, and monitor distributed field devices structured on a DeviceNet network. The hardware handles internal data mapping between the network device profiles and the designated PLC %I, %Q, %AI, and %AQ memory sub-registers.

Hardware Specifications

Deterministic Network Operations and Firmware Synchronization

The module integration uses a localized microcontroller to coordinate DeviceNet network execution without degrading host CPU cycle times. Internal serial data blocks align with deterministic networks like EtherNet/IP and Profinet, enforcing strict packet execution timelines over the physical transceiver lines. All data exchanges map directly through the standard backplane, maintaining uniform firmware flash compatibility with Series 90-30 CPU modules running standard hardware configurations.

Frequently Asked Questions

Q: Does the IC693DNM200 module draw its network operational power entirely from the PLC backplane?

A: No. While the internal logic processing circuitry is powered by the 5 VDC rail of the PLC backplane, the network physical layer transceivers require an external 24 VDC supply connected directly to the DeviceNet bus network tap.

Q: What happens to the slave outputs if the master module stops communicating or a network drop occurs?

A: The behavior depends on the configuration of each individual slave node. Slave hardware can be configured via the network management tool to either hold their last state or drop to a zero safety state upon losing the master heartbeat connection packet.

Field Installation Guidelines

• Network Termination: Install a standard 121 ohm, 0.25 W metal film resistor across the blue (CAN_H) and white (CAN_L) signaling lines at each physical end of the main trunk line to minimize signal reflections.
• Chassis Ground Grounding: Lock the module into the chassis rail, making certain the rear metal grounding clip contacts the backplane housing framework to establish a solid path for high-frequency electrical noise suppression limits.
• Separation of Traces: Route the DeviceNet drop cables through separate wiring conduits away from high-voltage AC motor lines and inductive power switching infrastructure to protect low-voltage digital bits from interference.
