Product Details

IC695CMM002 Product Description

The GE IC695CMM002 is a dual-port serial communication module engineered for the GE PACSystems RX3i platform, delivering robust RS-232 and RS-485 connectivity at the heart of modern industrial data architectures. In smart factory environments where every millisecond of data latency matters, the IC695CMM002 serves as a critical bridge between legacy field devices and contemporary Ethernet-based control networks — enabling seamless signal acquisition, protocol conversion, and real-time data transmission across the entire automation hierarchy.

From the moment a sensor signal is captured on the plant floor, the IC695CMM002 ensures that data travels reliably upward through the control stack: from field instruments and remote I/O modules, through the PACSystems RX3i backplane, across industrial Ethernet switches, and ultimately into SCADA platforms, HMI terminals, and cloud-based analytics dashboards. This unbroken data chain is the foundation of transparent, responsive, and scalable smart manufacturing.

In a fully connected smart factory, the IC695CMM002 occupies a pivotal position in the data flow architecture. At the field level, sensors — including temperature transmitters, pressure transducers, and flow meters — output analog or serial signals that are collected by remote I/O modules such as the GE IC694MDL660 discrete input module or the IC695ALG600 analog input module. These signals are routed into the PACSystems RX3i CPU, where the IC695CMM002 handles serial protocol communication with downstream devices that do not natively support Ethernet.

Variable frequency drives (VFDs) and servo controllers on production lines frequently rely on RS-485 Modbus RTU for parameter exchange and status reporting. The IC695CMM002 polls these drives — for example, communicating with GE AF-600 FP series drives — retrieving speed references, fault codes, and energy consumption data, then passing this information to the PACSystems RX3i CPU (IC695CPE305 or IC695CPE400) for real-time processing and PID loop control.

Above the controller layer, the GE IC695ETM001 Ethernet module connects the RX3i rack to the plant's industrial Ethernet backbone, typically running through managed industrial switches such as the GE EPSMGMT-008 or equivalent Layer 2/Layer 3 switches with VLAN segmentation. This Ethernet link carries processed data upward to SCADA servers running platforms like GE iFIX or Proficy Historian, where operators gain real-time visibility into production KPIs, alarm states, and trend data.

HMI panels — such as the GE QuickPanel+ IC754VSL06CTD — connect to the same Ethernet segment, providing operators on the shop floor with live dashboards, setpoint adjustment interfaces, and alarm acknowledgment screens. Meanwhile, edge gateway devices aggregate data from multiple RX3i racks and push structured datasets to MES or cloud analytics platforms, enabling predictive maintenance algorithms and OEE calculations without disrupting real-time control cycles.

The IC695CMM002 also supports SNP and SNP-X protocols, allowing programming tools such as GE Proficy Machine Edition to communicate directly with the PACSystems CPU over a serial link — a critical capability for field commissioning, firmware updates, and diagnostic sessions in environments where Ethernet access is restricted or unavailable.

This complete data chain — from sensor signal acquisition through serial protocol conversion, Ethernet transmission, SCADA visualization, and remote diagnostics — demonstrates why the IC695CMM002 is a foundational component in GE-based smart factory architectures. Its dual-port design allows simultaneous communication with two independent serial device networks, maximizing backplane slot efficiency and reducing overall system cost.

Protocol Fragmentation: Many industrial sites operate a mix of legacy RS-232 instruments, RS-485 Modbus RTU devices, and modern Ethernet-based controllers. The IC695CMM002 resolves this fragmentation by acting as a native serial gateway within the PACSystems RX3i rack, eliminating the need for external protocol converters and reducing potential points of failure in the communication chain.

Data Islands and Blind Spots: Without proper serial integration, field devices such as barcode scanners, weighing terminals, and legacy PLCs remain isolated from the plant's data network. The IC695CMM002 connects these devices directly to the RX3i CPU, making their data available to SCADA, MES, and historian systems — transforming data islands into fully visible nodes on the factory network.

Remote Monitoring and Diagnostics: The IC695CMM002 supports remote diagnostic access via SNP protocol, enabling engineers to interrogate controller status, review communication error logs, and adjust serial port parameters without physical site visits. Combined with the IC695ETM001 Ethernet module and a secure VPN gateway, remote teams can monitor communication health, identify CRC errors or timeout faults, and implement corrective actions in real time.

Production Line Transparency: By integrating serial-connected drives, sensors, and instruments into the PACSystems data model, the IC695CMM002 enables production line transparency — every device's status, output, and fault condition becomes visible in the SCADA historian, supporting alarm tracking, root cause analysis, and continuous improvement initiatives.

System Scalability: The modular RX3i architecture allows additional IC695CMM002 modules to be added to the backplane as communication requirements grow, supporting phased smart factory rollouts without requiring controller replacement or network redesign.

Q1: What communication protocols does the GE IC695CMM002 support, and is it compatible with Modbus RTU devices? The IC695CMM002 natively supports RS-232 and RS-485 physical interfaces, along with GE SNP and SNP-X protocols. Modbus RTU communication is achievable through user-configured serial messaging within the PACSystems RX3i CPU logic, making it compatible with a wide range of third-party drives, sensors, and instruments that use Modbus RTU over RS-485.

Q2: How does the IC695CMM002 ensure network stability and minimize communication latency in high-speed automation applications? The IC695CMM002 operates as a backplane-resident module, communicating directly with the PACSystems RX3i CPU over the high-speed internal bus rather than through an external network interface. This architecture minimizes communication latency and eliminates external cable-related interference. Each serial port supports baud rates up to 115.2 kbps, and the module's hardware-level error detection (parity, framing, overrun) ensures data integrity even in electrically noisy industrial environments.

Q3: Can the IC695CMM002 be integrated with GE iFIX SCADA or Proficy Historian for real-time data visualization? Yes. The IC695CMM002 works in conjunction with the PACSystems RX3i CPU and the IC695ETM001 Ethernet module to expose serial device data to the plant's Ethernet network. GE iFIX SCADA and Proficy Historian connect to the RX3i CPU via the SRTP Ethernet driver, reading all data — including values collected by the IC695CMM002 from serial devices — in real time. This enables full data visualization, trend logging, and alarm management without additional middleware.
