Detailed Parameter Table

Product Introduction

The IC697CMM742-LL is an advanced communication interface module developed by GE for its PACSystems RX3i platform—designed to enhance the network connectivity of RX3i controllers like the IC698CPE030-GJ and IC698CPE040. Unlike basic communication modules that support only standard protocols, the IC697CMM742-LL specializes in real-time and industrial-grade connectivity, with PROFINET IRT (Isochronous Real-Time) as its flagship feature—critical for applications requiring sub-millisecond synchronization between distributed devices.

As a key expansion component for the RX3i ecosystem, the IC697CMM742-LL addresses a critical gap in the IC698CPE030-GJ’s native capabilities: while the IC698CPE030-GJ supports Ethernet/IP and Modbus, it requires the IC697CMM742-LL to integrate with PROFINET-based devices (e.g., Siemens PLCs, Bosch Rexroth drives). This module enables seamless data exchange between the IC698CPE030-GJ and multi-vendor industrial systems, making it indispensable for mixed-protocol environments like automotive manufacturing or multi-site process plants. For plant engineers, the IC697CMM742-LL uses the same Proficy Machine Edition software as the IC698CPE030-GJ, ensuring unified configuration and monitoring without additional training.

Core Advantages and Technical Highlights

PROFINET IRT for Sub-Millisecond Synchronization: The IC697CMM742-LL’s support for PROFINET IRT (cycle time <1 ms) is a game-changer for real-time applications. In an automotive assembly line, the IC698CPE030-GJ (controlling conveyor logic) uses the IC697CMM742-LL to sync with PROFINET-enabled robotic arms—ensuring part placement accuracy within ±0.1 mm. Unlike standard PROFINET modules (cycle time >10 ms), IRT minimizes jitter to <100 µs, critical for high-speed processes like robotic welding or precision packaging. This capability expands the IC698CPE030-GJ’s applicability to industries that previously required more expensive controllers like the IC698CPE040.

Multi-Protocol Integration for Mixed-Vendor Environments: The IC697CMM742-LL supports four key industrial protocols simultaneously—PROFINET IRT, Ethernet/IP, Modbus TCP, and Modbus RTU—eliminating the need for multiple single-protocol modules. In a food processing plant, the IC698CPE030-GJ uses the module to communicate with: Ethernet/IP-enabled temperature sensors (IC698MDL754), PROFINET-based VFDs (for mixers), and Modbus RTU scales (for ingredient dosing). This integration reduces rack space usage by 40% compared to using separate modules and lowers communication latency by centralizing data routing through the IC697CMM742-LL.

Seamless Compatibility with RX3i Controllers: A standout feature of the IC697CMM742-LL is its plug-and-play integration with the IC698CPE030-GJ—no custom wiring or firmware patches are needed. The module draws 5 V DC power directly from the RX3i backplane, and its configuration is managed via Proficy Machine Edition (the same tool used for the IC698CPE030-GJ). For example, when adding the IC697CMM742-LL to an existing IC698CPE030-GJ system, engineers simply enable PROFINET IRT in the controller’s software and map I/O points to the module—setup takes less than 30 minutes, compared to 2+ hours for third-party communication modules.

Rugged Design for Industrial Reliability: Built to match the IC698CPE030-GJ’s environmental resilience, the IC697CMM742-LL operates in -25°C to 70°C and withstands 5%–95% non-condensing humidity. Its metal EMI shielding blocks interference from nearby motors or VFDs—a common issue in manufacturing facilities—while ESD protection (±15 kV air) prevents damage during maintenance. With an MTBF exceeding 400,000 hours, the module matches the IC698CPE030-GJ’s reliability, ensuring continuous communication in 24/7 operations like pharmaceutical batch processing.

Typical Application Scenarios

In automotive body-in-white (BIW) manufacturing, the IC697CMM742-LL enables the IC698CPE030-GJ to control a robotic welding cell. The module connects the IC698CPE030-GJ to 8 PROFINET IRT-enabled welding robots, synchronizing their movements with a cycle time of 0.8 ms—ensuring welds are aligned within ±0.05 mm. The IC697CMM742-LL also communicates with Ethernet/IP-based vision systems (via its second Gigabit port) to inspect weld quality, sending defect data back to the IC698CPE030-GJ for real-time adjustments. This integration reduces welding defects by 12% compared to using non-IRT communication.

In a multi-site water treatment plant, the IC697CMM742-LL links the IC698CPE030-GJ (local controller) to a central SCADA system and remote PROFINET pumps. The module uses Modbus TCP to send flow/pressure data (from IC698MDL754 modules) to the SCADA system, while PROFINET IRT controls remote pump VFDs—reducing latency compared to traditional Modbus RTU. During a pipe burst, the IC697CMM742-LL enables the IC698CPE030-GJ to shut down remote pumps in <200 ms, minimizing water loss by 80% compared to legacy communication methods.

In a pharmaceutical packaging line, the IC697CMM742-LL integrates the IC698CPE030-GJ with PROFINET-enabled labelers and Ethernet/IP barcode scanners. The module synchronizes label application with product movement (cycle time 1 ms), ensuring labels are placed correctly on 100% of packages. It also uses OPC UA to send production data to the plant’s MES system, enabling compliance with FDA 21 CFR Part 11. The IC697CMM742-LL’s SIL 2 compliance ensures no communication failures during critical batch packaging, avoiding costly product recalls.

Installation, Commissioning and Maintenance Instructions

Installation preparation for the IC697CMM742-LL requires mounting it in an empty 3U slot of the RX3i rack (adjacent to the IC698CPE030-GJ for optimal backplane communication). Tools needed include a torque screwdriver (0.5–0.8 N·m) and Ethernet cable tester. Verify the RX3i backplane provides stable 5 V DC (via IC698PWR101) and that the rack has adequate ventilation (15 cm clearance above/below). Never install the IC697CMM742-LL in a slot occupied by an I/O module—this will cause backplane conflicts with the IC698CPE030-GJ.

Commissioning steps: (1) Power on the RX3i rack—confirm the module’s “PWR” LED is green (indicates backplane power); (2) Launch Proficy Machine Edition, detect the IC697CMM742-LL via the IC698CPE030-GJ’s Ethernet port, and update the module’s firmware to match the controller’s version; (3) Configure protocols: enable PROFINET IRT on Port 1 (set cycle time to 1 ms for real-time apps) and Ethernet/IP on Port 2; (4) Map I/O points between the IC698CPE030-GJ and IC697CMM742-LL (e.g., link robotic position data to controller registers); (5) Test communication: send a test signal from a PROFINET device to the IC698CPE030-GJ via the module and confirm latency <2 ms.

Maintenance suggestions: Conduct monthly checks via Proficy Machine Edition—monitor protocol status (ensure PROFINET IRT cycle time is stable) and port link integrity. Every 6 months, clean the module’s Ethernet ports with compressed air (30 psi max) to remove dust. If a protocol fails (e.g., PROFINET IRT drops), reset the module via software (no need to power down the IC698CPE030-GJ) and re-test. Annual maintenance includes verifying EMI shielding integrity (inspect for dents) and re-calibrating PROFINET IRT cycle times. Replace only with GE-authorized IC697CMM742-LL spares—third-party modules may not support PROFINET IRT or integrate with the IC698CPE030-GJ.
