GE IC697CMM711

Product Introduction

The GE IC697CMM711 is a reliable communication interface module designed for GE’s Series 90-70 PLC platform, specializing in connecting PLC systems to Modbus-based networks and basic Ethernet/IP devices. As a predecessor to the high-performance IC697CMM742-GH, it focuses on cost-effective protocol conversion and data bridging for 中小型 industrial applications—avoiding the complexity of multi-protocol convergence while meeting core communication needs.

Equipped with a Fast Ethernet port and dedicated RS-485 interface, the IC697CMM711 resolves connectivity gaps between Series 90-70 PLCs and legacy Modbus sensors, HMI panels, or data logging systems. Unlike the gigabit-capable IC697CMM742-GH, it targets scenarios where 100 Mbps Ethernet bandwidth and basic protocol support suffice (e.g., batch processing lines, small-scale manufacturing cells). Its compact form factor and low power consumption make it ideal for space-constrained control cabinets, while retaining compatibility with GE’s mature configuration tools for seamless integration.

Synergy with Series 90-70 CPUs (e.g., IC697CPU781-HB)

The IC697CMM711 operates as a “lightweight communication gateway” for Series 90-70 CPUs, balancing functionality and resource efficiency. Their integration follows a two-layer architecture:

1. Backplane Data Exchange Layer

The module occupies any I/O slot (2-20) of the Series 90-70 rack, communicating with the CPU via the 10 Mbps synchronous backplane.

Real-time data transfer uses GE’s “Cyclic Data Exchange” protocol, ensuring <5 ms latency between the module and CPU—sufficient for non-critical control tasks.

Configuration synchronization: Proficy Machine Edition pushes shared parameters (e.g., Modbus register maps, IP addresses) to both the CPU and module, enabling plug-and-play setup.

2. Protocol Handling Layer

The IC697CMM711 offloads Modbus frame processing (encoding/decoding) and Ethernet/IP adapter functions from the CPU, freeing up processing resources for core logic.

The CPU focuses on ladder logic execution and I/O control, with the module acting as a transparent bridge to external devices.

Example: In a packaging line, the CPU manages conveyor speed and packaging sequence while the module collects data from 16 Modbus RTU pressure sensors and transmits it to a local HMI via Ethernet/IP.

Core Advantages and Technical Highlights

1. Cost-Effective Modbus Convergence

The module integrates Modbus TCP and RTU protocols in a single device, reducing hardware costs by 30% compared to deploying separate Ethernet and RS-485 modules. Key capabilities include:

Modbus Master/Slave Flexibility: Acts as a Modbus TCP master to poll up to 16 slave devices, or as a slave to receive commands from SCADA systems.

RTU-to-TCP Conversion: Translates Modbus RTU data from legacy sensors to Modbus TCP for the CPU, eliminating the need for external protocol converters.

Ethernet/IP Adapter Mode: Connects to Rockwell Allen-Bradley HMI panels via Ethernet/IP explicit messaging (up to 16-byte input/output data).

2. Simplified Configuration & Maintenance

Designed for ease of use, the module offers:

Tool Compatibility: Works with both legacy CIMPLICITY Machine Edition and modern Proficy Machine Edition, supporting smooth upgrades from older GE systems.

Plug-and-Play Detection: The CPU automatically identifies the module via backplane scan, reducing setup time by 40% vs. third-party communication modules.

Intuitive Diagnostics: LED indicators for power, Ethernet link/activity, RS-485 activity, and faults enable at-a-glance status checks—critical for rapid troubleshooting.

3. Reliable Performance for Basic Applications

The module delivers consistent performance for non-high-speed scenarios:

Stable Connectivity: RS-485 interface supports 1200 bps to 115.2 kbps baud rates with parity/stop bit configuration, compatible with most legacy Modbus devices.

Environmental Resilience: Withstands 0°C to 60°C operating temperatures and 30 g shock, matching the durability of Series 90-70 CPUs for industrial environments.

Low Power Consumption: 0.8 A @ 5 V DC power draw is 33% lower than the IC697CMM742-GH, reducing load on the rack power supply.

Typical Application Scenarios

1. Small-Scale Food Processing Plant

A snack manufacturing facility uses IC697CMM711 with IC697CPU771 to monitor production lines:

Module Role: Modbus RTU master (polls 12 temperature sensors and 4 flow meters) + Modbus TCP slave (sends data to a local SCADA server).

CPU Role: Executes basic PID control for oven temperature and mixer speed.

Outcome: 25% reduction in integration costs vs. using a multi-protocol module; 99.9% network availability.

2. Legacy Equipment Retrofit

A textile mill upgrades its 20-year-old control system with IC697CMM711 and IC697CPU781-HB:

Module Role: Converts Modbus RTU data from 20 legacy looms to Ethernet/IP for a new Rockwell HMI.

CPU Role: Adds modern quality control logic (e.g., thread tension monitoring) using module-provided data.

Benefit: Avoided $150k in loom replacement costs; reduced downtime from 8 hours/week to 2 hours/week.

3. Water Treatment Plant

A municipal water treatment facility uses the module for data logging:

Module Role: Acts as a Modbus TCP master to poll 32 level sensors and transmit data to a cloud-based monitoring platform via Ethernet.

CPU Role: Manages pump operation and chemical dosing based on sensor data.

Key Value: Simplified setup enabled remote monitoring; compliance with local environmental data reporting requirements.

Installation, Commissioning and Maintenance

Installation Preparation

Power off the Series 90-70 rack and wear an anti-static wristband. Ensure the target slot (2-20) is vacant and the IC697PWR701 supply can support additional 0.8 A @ 5 V DC.

Gather tools: Phillips screwdriver, torque wrench (4.5 N·m), Fast Ethernet cables (CAT5e), RS-485 shielded cable, and PC with Proficy Machine Edition (v9.0+).

Verify environment: 0°C to 60°C temperature, 5%-95% RH (non-condensing). Ensure proper ventilation for the rack.

Commissioning Steps

Hardware Installation: Insert the module into the rack, secure with screws (4.5 N·m torque), and connect Ethernet/RS-485 cables. Power on the rack—confirm green Power LED and no red Fault LED.

Configuration Setup:

Launch Proficy Machine Edition, connect to the CPU (via RS-232/Ethernet), and detect the IC697CMM711 via backplane scan.

Configure network settings: Assign an IP address to the module and set Modbus parameters (baud rate, parity, register offsets).

Map module data to CPU tags: e.g., link Modbus RTU sensor data (register 0x0001) to CPU tag “Sensor_Temp”.

Function Testing:

Modbus RTU: Send a read request from the module to a slave device (address 0x01, register 0x0000) and confirm data matches CPU display.

Ethernet/IP: Connect a Rockwell HMI to the module and verify real-time data updates.

Maintenance Guidelines

Daily: Check Power LED (green = active) and Ethernet Link/Activity LED (green = link up, amber = activity). Verify no red Fault LED.

Weekly: Inspect Ethernet/RS-485 connectors for tightness and corrosion. Clean module vents with a soft brush.

Monthly: Use Proficy Machine Edition to run “Communication Diagnostic Scan”: check Modbus error rates and backplane communication status.

Quarterly: Update module firmware (via GE Support Portal) to resolve compatibility issues with newer CPUs.
