Key Features

1. Dual-Port Flexibility: Port 1 dedicated to RS-232; Port 2 switchable between RS-232, RS-422, or RS-485 for multi-device connectivity.
2. Multi-Protocol Support: Natively supports CCM, Modbus RTU, and SNP protocols for seamless integration with GE and third-party devices.
3. Coprocessor Offloading: Dedicated communication processor reduces main CPU load, improving system performance and responsiveness.
4. High-Speed Communication: Baud rates up to 19.2Kbps enable fast data exchange for real-time monitoring and control.
5. Wide Distance Coverage: RS-485 mode supports communication distances up to 1,200 meters (4,000 ft) for distributed systems.
6. LED Status Indicators: Separate LEDs for COMM, TX, RX, and ERROR provide immediate visual diagnostics.
7. Reset Button: Onboard push-button restarts communication without resetting the entire PLC system.
8. Compact & Rugged: Industrial-grade plastic housing with IP20 protection suits cabinet mounting in harsh environments.
9. Easy Configuration: Setup via Logicmaster 90-30 or Proficy Machine Edition software; supports default configurations for quick deployment.
10. Hot-Swappable: Supports hot insertion/removal for system expansion or replacement without downtime.

Applications

• HMI & SCADA Connectivity: Links Series 90-30 PLCs to GE Fanuc HMIs, Cimplicity SCADA, and third-party operator interfaces via RS-232/485.
