The GE Fanuc Series 90-30 IC693CMM321 Ethernet interface TCP/IP module provides comprehensive PLC system diagnostics and maintenance capabilities. This module facilitates data transfer from the PLC to other devices and supports simultaneous communication with multiple devices, accommodating up to 16 server connections. While one or two modules can be installed in any Series 90-30 baseplate, they are not compatible with GE handheld programmers from the Series 90-30/20/Micro product lines.
The IC693CMM321 features 2 ports and 4 LED indicators for comprehensive status monitoring. The ports include the Station Manager Port and Firmware Upgrade Port, while the LED indicators (OK, LAN, SER, and STAT) provide clear visibility into module and network operational status.
