The HE693DNT250 is a DeviceNet Master/Scanner communication module designed for the GE Fanuc Series 90-30 PLC platform.
This module enables seamless integration of DeviceNet field networks into the Series 90-30 backplane, allowing the PLC to exchange cyclic I/O data and explicit messages with distributed field devices.
Key capabilities include:
Master/Scanner mode operation
Centralized control of remote I/O and smart devices
Reduced field wiring through network architecture
Enhanced diagnostics and device-level visibility
The module occupies a single slot on the 90-30 baseplate and is optimized for low-latency communication in motion-sensitive and high-speed industrial systems.

Does it support explicit messaging (UCMM)?
Yes. It supports both polled I/O data exchange and explicit messaging for device configuration and diagnostics.
What software is used for configuration?
Configuration is typically performed using Proficy Machine Edition or compatible DeviceNet configuration tools.
Is external power required?
The module draws logic power from the PLC backplane. However, the DeviceNet network requires a separate 24 VDC supply to power field devices and the bus transceiver.
