More Information

Overview Manuals Applications Media Interfaces Protocol Services Diagnostics

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.

  • 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.
Description
General Electric IC693CMM321 adds industrial Ethernet communication to a modular Series 90-30 PLC without changing the controller's established rack architecture. It provides a network path for programming, supervisory access and controller data exchange, helping installed automation systems communicate with plant-level equipment through standard TCP/IP infrastructure.

SRTP services form the native communications layer, while supported hardware and firmware revisions also provide Modbus TCP master and slave functions. This combination allows the interface to serve GE controller traffic and selected open-protocol integrations, making it useful when an existing Series 90-30 system must exchange data with newer HMIs or supervisory hosts.

The module family spans several physical-interface generations, so its connector layout is part of the product identity rather than a cosmetic variation. Early hardware relies on AAUI media equipment, later revisions add direct twisted-pair Ethernet, and the latest documented units omit AAUI, making the complete revision suffix essential during maintenance planning.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why is the complete IC693CMM321 revision suffix required?
The suffix identifies the physical Ethernet interface and supported firmware path. An AAUI-era unit and a later RJ45-only unit are not connected in the same way.
Which IC693CMM321 revisions support Modbus TCP?
GE introduced Modbus TCP master and slave operation with firmware 3.10 for supported Fx-and-later hardware; confirm the installed suffix and firmware before configuration.
Does every IC693CMM321 require an external Ethernet transceiver?
No. Early AAUI hardware does, while later versions provide direct 10Base-T and the documented KL/KN hardware removes AAUI.
What is the main risk during an IC693CMM321 firmware update?
Interrupting rack power while flash memory or the software loader is being programmed can leave affected hardware inoperative.
What security check is needed on an IC693CMM321-KN?
The Station Manager password must be changed from its default value and network access should follow the controls described for firmware 3.20.
Which manuals should be used for IC693CMM321 engineering?
Use GFK-1541 for TCP/IP Ethernet communications, GFK-1186 for Station Manager and the matching GFK-1085 product-information revision.
What should accompany an IC693CMM321 quotation request?
Send the complete two-letter suffix, firmware, existing connector layout, IP configuration, required condition, destination and quantity.
