Overview of Omron PLC CJ1W-SCU31-V1

The Omron CJ1W-SCU31-V1 is a serial communication control unit for CJ-series PLCs featuring two serial ports supporting RS-422A/485 and RS-232C protocols. It enables versatile, high-speed serial communication for flexible integration into industrial networks and automation systems.

Key Features

  • Two serial ports: Port 1 supports RS-422A/485 and Port 2 supports RS-232C communication.
  • Supported protocols include Host Link, Protocol Macro, Serial Gateway, No-protocol, NT Link, and Modbus-RTU Slave (from Unit Ver. 1.3).
  • Communication speed up to 230,400 bps for fast data exchanges.
  • Communication distance: RS-422A/485 up to 500 m, RS-232C up to 15 m.
  • Supports half-duplex and full-duplex modes with start-stop asynchronous synchronization.
  • Allocates 25 words in CPU Bus Unit CIO area and 10 words per serial port in DM area for data exchange.
  • Simple backup function to save Protocol Macro data on CPU memory card (compatible with CJ1-H and CJ1M CPU Units).
  • Current consumption: approx. 280 mA at 5 V.
  • Compact size: 90 mm (H) × 31 mm (W) × 65 mm (D), weight approx. 110 g.
  • Complies with general specifications for Omron CJ-series.
