Industrial SCADA & Serial Communication Solution – GE IC693CMM302 | Series 90-30
Where This Product Is Used
The GE IC693CMM302 Communication Module (CCM) is engineered for mission-critical industrial environments where reliable serial data exchange is non-negotiable. Typical deployment scenarios include:
- SCADA & DCS Integration: Connects Series 90-30 PLCs to supervisory control systems via RS-232/RS-422/RS-485 serial protocols, enabling real-time process monitoring in oil & gas, water treatment, and power generation plants.
- Manufacturing Execution Systems (MES): Bridges shop-floor PLC data to MES platforms in automotive, food & beverage, and pharmaceutical production lines.
- Legacy System Modernization: Provides a cost-effective serial communication path for existing Series 90-30 installations requiring protocol conversion without full system replacement.
- Remote Terminal Unit (RTU) Communication: Used in pipeline monitoring, substation automation, and remote I/O applications requiring point-to-point or multi-drop serial links.
- Machine-to-Machine (M2M) Communication: Facilitates data exchange between PLCs and third-party devices such as drives, HMIs, barcode readers, and weighing systems.

Why Engineers Specify This Model
- Dual Independent Serial Ports: Two fully independent channels allow simultaneous communication with multiple devices or networks, eliminating the need for external serial splitters.
- Protocol Flexibility: Software-selectable RS-232/422/485 and support for SNP, SNP-X, and ASCII protocols make this module adaptable to virtually any serial device in the field.
- Co-Processor Architecture: Offloads communication processing from the main CPU, ensuring deterministic PLC scan times are not impacted by communication overhead — critical in high-speed process control.
- Proven Reliability: Designed to GE’s industrial-grade standards with wide temperature tolerance and vibration resistance for harsh plant environments.
- Drop-in Compatibility: Fits any Series 90-30 rack slot without hardware modification, simplifying upgrades and spare-parts management.

Application-Specific FAQ
Q: Can the IC693CMM302 communicate using Modbus RTU?
A: Yes. While the module natively supports GE’s SNP/SNP-X protocols, Modbus RTU communication can be implemented via ladder logic using the module’s ASCII/RTU serial ports. Many system integrators use this approach to interface with third-party drives and meters.
Q: Is this module compatible with the Series 90-30 CPU374 (Ethernet CPU)?
A: Yes. The IC693CMM302 occupies a standard backplane slot and is fully compatible with all Series 90-30 CPUs, including the IC693CPU374. It operates independently of the CPU’s Ethernet port.
Q: What is the maximum cable length for RS-485 multi-drop networks?
A: RS-485 supports cable runs up to 1,200 meters (4,000 ft) at lower baud rates. For the IC693CMM302, GE recommends shielded twisted-pair cable (Belden 9842 or equivalent) and proper termination resistors at both ends of the bus.
Q: Can I use two IC693CMM302 modules in the same rack?
A: Yes. Multiple CCM modules can coexist in the same rack, each assigned a unique slot address. This is common in applications requiring more than two serial communication channels.
Q: Do you provide a warranty?
A: All units sold by Konmask.com carry a minimum 90-day functional warranty. Extended warranty options are available upon request.
