IC693CMM321 GE Ethernet interface module

The IC693CMM321 is an Ethernet interface module that is part of the Series 90-30 Programmable

Logic Controller (PLC) platform. This module is manufactured by GE Fanuc automation that is primarily

used to directly interface a Series 90-30 baseplate to an existing ethernet network for the purpose of implementing

distributed I/O or allow CPU and communication adapters communicate to remote stations, Human Machine

Interface (HMI), Supervisory Control and Data Acquisition (SCADA) and Distributed Control Systems (DCS).

IC693CMM321

The IC693CMM321 feature a variety of communication to perform different tasks. This module has One (1) RS-232,

RJ-11 Serial Port acting as the Station Manager Port, One (1) RS-485, 15-pin, D-type Serial Port used as Software

Loader Port and One (1) AAUI Port that is used as Network Port for connecting the module to the Ethernet network. This

module is also provided with LED indicators that allow user to monitor the operation of each port and overview of the module’s

status. These indicators are OK, LAN, SER and STAT. Respectively, LED indicators depict the state of Interface is in, existing

traffic on the Transceiver port and Downloader port, and presence of an exception event.
