Description

Designed to facilitate high-speed, multi-point serial data exchange within PLC systems, the CJ1W-SCU32 functions as a high-performance serial high-speed communication unit for Omron CJ-series controller configurations. This CPU Bus Unit mounts directly to the backplane, providing two high-speed serial ports configured for RS-422A/485 communications. It supports various protocols, including Modbus-RTU Easy Master, No-Protocol, Host Link, and Protocol Macros, allowing seamless integration with variable speed drives, temperature controllers, and third-party serial devices.

Features

  • Dual RS-422A/485 serial communication ports.
  • High-speed transmission rates up to 230.4 kbps for fast data throughput.
  • Supports Protocol Macros, Host Link, No-Protocol, NT Link, Modbus-RTU Master, and Modbus-RTU Slave.
  • Mounts directly to the CJ-series CPU Bus on the controller backplane.
  • Simplifies serial network topologies with multi-drop configurations.

Applications

  • Industrial automated assembly lines utilizing distributed remote I/O.
  • Integration of temperature controllers, power meters, and barcode readers.
  • Control of variable frequency drives (VFDs) and servo systems via Modbus.
  • Substation monitoring and SCADA integration.
