About the project

The entry-level modular PLC with a big potential


  The smallest members of the CJ1 family are fully upward-compatible to the CJ1G/H and CS1 series regarding instruction set, communication commands and memory organization. Now even small machines can be built in a consistently modular way, reducing the cost to enhance, expand or customize machines without a complete redesign of the control system.

  • Entry-level modular PLC, compatible with CJ1G/H-series.
  • CPUs with built-in pulse I/O for fast and easy motion control, or with Ethernet interface for easy integration.
  • IEC 61131-3 Structured Text programming, extensive function block libraries.
  • Transparent communication routing through different networks.
  • Compact Flash memory card slot for data storage and program exchange.
