Features:
- Adds 10 Mbit/s TCP/IP Ethernet communication to a modular Series 90-30 rack.
- Supports SRTP services and revision-dependent Modbus TCP master and slave operation.
- Uses hardware-specific media interfaces that must be matched by complete revision suffix.
The current catalog family is the IC693CMM321 Ethernet interface, whose exact media hardware and firmware capability are identified by the two-letter suffix.
It lets PLC logic initiate network transfers while host systems and compatible controllers access selected Series 90-30 data over TCP/IP.
Before replacement, record the full suffix, firmware, IP parameters, transceiver or RJ45 arrangement, Station Manager access and every configured exchange or communication request.
Availability is subject to Apter Power inventory and sourcing confirmation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Connects legacy Series 90-30 controller data to compatible HMI and supervisory systems over industrial Ethernet.
- Supports PLC-initiated communication with compatible GE controllers and network devices through configured requests.
- Provides a retained Ethernet path during staged migration of installed Series 90-30 control systems.
- Early revisions use an AAUI connection and require a matching external transceiver for the selected Ethernet medium.
- Revision FG introduced a direct 10Base-T interface while retaining revision-specific hardware differences.
- Revision KL and the later KN release omit the AAUI port, so connector availability must be checked from the label.
- SRTP provides native GE controller and programming communications across the Ethernet LAN.
- Supported firmware implements Modbus TCP master and slave functions for external data exchange.
- PLC logic uses configured communication requests while the interface reports completion and network status.
- Station Manager provides local commands for network setup, statistics, exception review and service functions.
- Front indicators report module, LAN, serial or duplex activity according to the installed hardware revision.
- Firmware updates require the documented Station Manager connection and uninterrupted rack power throughout flash programming.
