1. Product Description
The IC693CMM302 acts as a bridge between Series 90-30 PLCs (e.g., IC693CPU331) and up to 31 Genius bus devices (sensors, drives, remote I/O). Key features include:
- Dual Protocol Support: Native Genius bus for high-speed control (500 kbps) and SNP/Modbus RTU for legacy system integration.
- Global Data Synchronization: 128 bytes of transmit/receive data for real-time monitoring of process variables.
- Flexible Installation: Mounts directly on the CPU baseplate or expansion racks, reducing cabling complexity.
- Diagnostic LEDs: Real-time status indicators for bus activity and module health, minimizing downtime.

3. Advantages and Features
- Reliability: MTBF of 1,200,000 hours (GE testing), with conformal coating for vibration resistance in factory floors.
- Scalability: Supports 31 devices per bus—2x more than legacy modules—ideal for expanding production lines.
- Cost Efficiency: Reduces wiring costs by 40% compared to hardwired systems through centralized bus control.
- Legacy Compatibility: Retains SNP protocol support for seamless integration with GE’s older Micro PLCs.
4. Application Areas and Use Cases
Industries:
- Automotive (robotics, weld gun control)
- Water treatment (pump station automation)
- Food & beverage (conveyor systems)
Case Study:
A Mexican automotive plant used IC693CMM302 modules to connect 28 remote I/O stations on a Genius bus for its paint shop. The modules reduced commissioning time by 25% and improved fault detection speed by 30%, cutting annual downtime by $80,000.

5. Competitor Comparison
The IC693CMM302 outperforms similar modules in:
- Native Genius Support: Eliminates third-party gateways, unlike generic Modbus-only alternatives.
- Dual Ports: RS-232 + RS-485 vs. single-port modules, enabling simultaneous HMI and field device connectivity.
- Temperature Range: Operates at 60°C (10°C higher than most legacy-compatible modules).

6. Selection Guidelines
- System Type: Choose the IC693CMM302 for Series 90-30 PLCs; opt for IC697CMM711 for newer RX7i systems.
- Device Count: Use one module for ≤31 devices; add more for larger networks (e.g., 3 modules for 93 devices).
- Budget: Refurbished units from Shanxi Xinyeda cost 35% less than new, with a 1-year warranty.
7. Precautions
- Bus Termination: Always install 120Ω terminators at bus ends to prevent signal reflections.
- Firmware: Update via Proficy Machine Edition to unlock SNP v2.0 features (e.g., enhanced error handling).
- ESD Protection: Use anti-static gloves during installation—static discharge can damage the RS-485 transceiver.
- Power Sequencing: Power up the PLC before Genius bus devices to ensure stable initialization.
