Functional Description

IC697CMM742 is an Ethernet Interface Module developed by GE. It is a part of Mark I and II control system. With versatile network port options, easily upgradeable firmware, and comprehensive diagnostic tools, this module enhances the efficiency and reliability of control systems across complex Ethernet-based networks.

Features

• Connect the IC697 PLC to an IEEE 802.3 CSMA/CD 10 Mbps Ethernet LAN using one of three network ports: 10BaseT, 10Base2, or AUI. Both 10BaseT and 10Base2 network ports allow direct network connection without requiring an external transceiver, while the standard 15-pin AUI port supports various media options, including 10Base5, 10Base2, 10BaseT, 10BaseF, or 10Broad36, using a user-supplied 802.3-compatible transceiver.
• Preloaded firmware simplifies installation and is designed for indefinite maintenance. The firmware is also upgradeable directly in-system from a PC connected to the RS-485 serial port, enabling easy updates.
• Offers Ethernet Global Data (EGD) for configuration and logic-based data exchange, TCP/IP services via SRTP, full PLC programming and configuration, as well as comprehensive station management and diagnostic tools for optimal network management.

Functions

The Ethernet Interface provides high-performance TCP/IP communications specifically for IC697 PLC systems. It installs in a single slot within an IC697 PLC rack and is configured using the IC641 PLC programming software. Up to four Ethernet Interface (Type 2) modules can be installed in a single PLC CPU rack, enhancing scalability. The module includes three network ports: 10BaseT (RJ-45), 10Base2 (BNC), and AUI (15-pin D-connector), automatically selecting the active port as needed, though only one port can be active at a time.

Installation

• Station Address: Before installation, record the 12-digit default station address from the printed label on the Ethernet interface. A configuration data form is provided in the user manual for easy reference.
• Power Off the PLC Rack: Ensure that power to the IC697 PLC rack is off.
• Insert the Module: Slide the Ethernet Interface module into the designated slot, typically the first available to the right of the CPU or Bus Transmitter Module (BTM), and secure with the screws on the top and bottom tabs. Empty slots to the left of the module may disrupt operation.
• Connect to the Network: Connect the Ethernet Interface to the network via one of the three ports. If using an AUI port with an external transceiver, ensure the cable links to an IEEE 802.3-compatible transceiver. The Disable Onboard 10Base2 Port jumper should be in place if using an external transceiver that doesn’t need +12 VDC power from the AUI port.
• CPU Run/Stop: Set the CPU’s Run/Stop switch to “STOP.”
• Power On: Turn on the PLC rack.

Supported IEEE 802.3 Media

• 10Base5 (Thick Coax): Uses a 50-ohm coaxial cable with a maximum segment length of 500 meters, supporting up to 100 stations with a spacing multiple of 2.5 meters.
• 10Base2 (Thin Coax): A 50-ohm coaxial cable with a maximum segment length of 185 meters, supporting up to 30 stations.
• 10BaseT (Twisted Pair): Twisted pair cabling with a maximum length of 100 meters between nodes and a hub or repeater, supporting star wiring topologies.
• 10BaseF (Fiber Optic): Has two variations (10BaseFP and 10BaseFL), supporting distances from 500 to 2000 meters between nodes or repeaters.
• 10Broad36 (Broadband): Uses 75-ohm coaxial cable and CATV components, supporting hundreds of nodes over distances up to 2800 meters.
