Functional Description

IC697CMM742-FD is an Ethernet Interface Module developed by GE. It is a part of Mark I and II control system. It serves as a key networking component for GE's Series 90-70 PLC systems. This module facilitates high-speed communication and data exchange within Ethernet LAN environments, supporting robust industrial applications that rely on reliable network connectivity.

Features and Connectivity

The Ethernet Interface Module comes equipped with three network ports, which enable seamless communication between the IC697 PLC and Ethernet LAN. This network port is designed to industry standards with a 15-pin connector, supporting various Ethernet mediums, including:

• 10Base5 (Thicknet)
• 10Base2 (Thinnet)
• 10BaseT (Twisted Pair)
• 10BaseF (Fiber)
• 10Broad36 (Broadband)

Each medium choice requires a user-supplied 802.3-compatible transceiver for specific applications. This versatile connectivity ensures the IC697CMM742 module is suitable for diverse industrial setups where flexible networking options are needed.

Preloaded and Upgradeable Firmware

The Ethernet interface module is preloaded with firmware, allowing for easy setup and efficient installation. Furthermore, the firmware is designed for indefinite maintenance, supporting upgrades to meet evolving network and control system requirements. Communication protocols include configuration/logic-based Ethernet global data and TCP/IP through the Service Request Transport Protocol (SRTP), along with comprehensive PLC programming, configuration, and station management tools.

Diagnostic LEDs and Indicators

The module includes four main LED indicators that convey real-time operational statuses:

• MODULE OK: Lights up when the module has passed diagnostics and is functioning correctly. It blinks during diagnostic checks or indicates special operating conditions, while remaining off if there is a failure.
• LAN ONLINE: Indicates network connectivity status. It is on when the module is connected and ready for network communication, blinks during data transfer, and turns off if disconnected, disrupted, or malfunctioning.
• SERIAL ACTIVE: Shows data transfer activity on the RS-485 serial port. It blinks during data transfer and remains off during inactivity.
• STATUS OK: Indicates normal operation. It is on when the module is functioning correctly and turns off if an event occurs that requires user attention.

User-Accessible Maintenance Components

• LED Indicators: Four LEDs for real-time diagnostics and network activity.
• Restart Pushbutton: Provides module resetting and special operation options.
• Station Manager (RS-232) Serial Port: Used for configuration and maintenance tasks.
• Service Option Connector: An auxiliary port for specific service needs.
• Software Load (RS-485) Serial Port: Supports firmware updates and configurations.
• Network Ports: Supports multiple Ethernet standards, including 10BaseT, AUI, and 10Base2.
• MAC Address Label: Located inside the faceplate for identification.
• Replaceable +12 VDC Fuse: Offers electrical protection.
• Onboard Transceiver Power Disable Jumper (JP7): Typically uninstalled, this disables transceiver power if needed.

FREQUENTLY ASKED QUESTIONS

What is IC697CMM742-FD?
It is an Ethernet Interface Module developed by GE.

Which Ethernet standards does the Module support?
This module supports multiple Ethernet standards, including 10Base5 (Thicknet), 10Base2 (Thinnet), 10BaseT (Twisted Pair), 10BaseF (Fiber), and 10Broad36 (Broadband), providing flexibility in different network environments. An 802.3-compatible transceiver is required for each type of Ethernet connection.

Does the module come with preloaded firmware?
Yes, it comes with preloaded firmware for straightforward installation. The firmware is also upgradeable, enabling long-term support and compatibility with updated control systems.

How does the module handle communication protocols?
It supports Ethernet Global Data (EGD) for data exchange, TCP/IP communication via SRTP (Service Request Transport Protocol), and provides tools for full PLC programming and station management.

What functions does the restart button perform?
The restart button has four main functions- LED test, general restart, restart to enter software load state (for firmware updates), and restart to enter maintenance state.

How do I know if the module is connected to the network?
When connected and ready for communication, the LAN ONLINE LED will remain on. It will blink during data transfers and will turn off if there is a disconnection or network malfunction.
