IC697CMM742 Ethernet Interface for Series 90-70, Type 2
IC697CMM742 is a communication module for GE Fanuc 90-70 series PLCs. It allows for configuration of parameters such as protocol, baud rate, and address via GE programming software, eliminating the need for hardware jumpers and simplifying the debugging process. Equipped with two independent RS-485/RS-422 communication ports, it supports port redundancy or simultaneous connection to different devices, enhancing communication flexibility.
As a bridge facilitating the transition from traditional industrial control systems to modern network architectures, IC697CMM742 is widely used in manufacturing control systems, process automation and industrial networking solutions. It is a standard component for upgrading the GE Series 90-70 system to modern Ethernet communication.

Product Details
The IC697CMM742 Ethernet Interface (Type 2) provides high-performance TCP/IP communications for the IC697 PLC.
The Ethernet Interface (Type 2) plugs into a single slot in an IC697 PLC rack and is configured with the IC641 PLC programming software. Up to four Ethernet Interface (Type 2) modules can be installed in an IC697 PLC CPU rack. The Ethernet Interface (Type 2) contains three network ports: 10BaseT (RJ-45 connector), 10Base2 (BNC connector), and AUI (15-pin D-connector). The Ethernet Interface automatically selects the network port in use. One network port may be used at a time. The 10BaseT network port permits direct connection to a 10BaseT (twisted pair) network hub or repeater without an external transceiver.
The 10Base2 network port permits direct connection to a 10Base2 (ThinWire) network without an external transceiver.
The AUI network port permits attachment of a user-supplied AUI (Attachment Unit Interface, or transceiver) cable. The AUI cable connects the Ethernet Interface to a user-supplied transceiver that is directly connected to the 10Mbps Ethernet network. The transceiver must be 802.3 compatible and must have the SQE option enabled.
Transceivers are commercially available to operate on a variety of 10Μbps me, including 0.4-inch-diameter coaxial cable (10Base5), ThinWire coaxial cable (10Base2), twisted pair (10BaseT), fibre optic (10BaseF), and broadband cable (10Broad36).
The Ethernet Interface (Type 2) provides TCP/IP communications with other IC697 and IC693 PLCs, host computers running the Host Communications Toolkit or CIMPLICITY software, and computers running the TCP/IP version of the MS-DOS or Windows-based programming software. These communications use the proprietary SRTP and Ethernet Global Data protocols over a 4-layer TCP/IP (Internet) stack.

IC697CMM742 module indicator light
The Ethernet Interface board indicators consist of four Light Emitting Diodes (LEDs):
MODULE OK
LAN ONLINE
SERIAL ACTIVE
STATUS
Ethernet Interface (Type 2) LED Indicators:
| Indicator | Status | Description |
| MODULE OK |
ON OFF BLINKING |
This LED is ON if the Ethernet Interface has passed diagnostics and is operating properly. This LED is OFF if the module fails a diagnostic test or if a fatal failure is detected during operation. This LED is BLINKING during diagnostics or to indicate special operating conditions. * |
| LAN ONLINE |
ON
OFF
BLINKING |
This LED is ON when the Ethernet Interface is connected to the Ethernet network and is ready to communicate.
This LED is OFF when: - The Ethernet Interface is not communicating in the network due to a disconnection or disruption of the cable - The Ethernet Interface has malfunctioned. - The Ethernet Interface has been commanded not to enter the network
This LED is BLINKING when the Ethernet Interface is transferring data on the network, or to indicate special operating conditions. |
| SERIAL ACTIVE |
OFF
BLINKING |
This LED is OFF during inactivity at the RS-485 serial port
This LED is BLINKING during data transfer at the RS-485 serial port, or to indicate a special operation condition.s |
| STATUS OK |
ON
OFF
BLINKING |
This LED is ON when the module is operating without exception conditions.
This LED is OFF if the Ethernet Interface detects an event (exception condition) during operation that requires supervisory attention. In this case, refer to the PLC Fault Table for further information, as described in the Troubleshooting chapter of the User's manual.
This LED is BLINKING during special operating conditions |
* Special operating conditions are indicated by multiple LEDs blinking in unison:
- During the Software Load state, all LEDs blink in unison.
- During the Waiting for IP Address state, the MODULE OK and STATUS LEDs blink in unison.
- During the Maintenance state, the MODULE OK and SERIAL ACTIVE LEDs blink in unison.
IC697CMM742 Installation
1. Read and record the 12-digit Default Station Address from the printed label on the Ethernet Interface.
A Station Configuration Data Form is provided in the User's Manual for your convenience in recording the Station Configuration Information.
2. Be sure the IC697 PLC rack power is OFF
3. Slide the Ethernet Interface into the slot for which it was configured in the system - normally the first available slot to the right of the CPU or Bus Transmitter Module (BTM).
Press the board firmly in place, but do not force the board. Tighten the screws on the top and bottom tabs.
4. Connect one of the network ports on the Ethernet Interface to the Ethernet network. If you are using an external transceiver, connect the transceiver cable to the AUI port on the Ethernet Interface. The other end of the transceiver cable should be connected to an external IEEE 802.3 compatible transceiver that is connected to the Ethernet network.
5. Set the CPU Run/Stop switch to STOP.
6. Power up the PLC rack.
7. After the module is installed, the network parameters need to be set through the corresponding PLC configuration software of the GE series 90-70 (such as IC641), including:
IP address, subnet mask and gateway;
Network protocols and port configuration;
Network node management and name setting, etc.
FAQ
Q: Which network interfaces does IC697CMM742 support?
A: IC697CMM742 is equipped with three Ethernet physical interfaces:
10Base-T (RJ-45) standard Ethernet port
10Base-2 (BNC) ThinWire coaxial port
AUI (15-pin D-type interface)
Q: What do the LED indicators in the module represent?
A: There are 4 main LED indicators on the module:
MODULE OK - The module is self-tested and operating normally when this light is on; it is off when the self-test fail,s or there is a fault.
LAN ONLINE - Indicates that the network connection has been established; the data transmission is flashing.
SERIAL ACTIVE - Indicates that the serial port is transmitting data; the light goes off when the port is idle.
STATUS OK - Lights up when operating normally; turns off when an exceptional event occurs and requires attention.
Q: The network is not connected.
A: Check whether the 10Base-T/RJ-45 or 10Base-2/BNC link is properly connected.
Q: Can the module be installed in the expansion rack?
A: No. The IC697CMM742 must be installed in the main frame (CPU slot) of the PLC. Installing it in the expansion frame will cause the module to malfunction or fail to connect to the network.
