CJ-Series communication units Modular PLC Open to any communication The CJ-Series offers both standardised open networks interfaces, and cost-efficient high-speed proprietary network links. Datalinks between PLCs, or to higher-level in- formation systems can be made using serial or Ethernet links, or the easy-to-use con- troller link network. Omron supports the 2 major field networks, DeviceNet and PROFIBUS-DP. For high- speed field I/O, Omron's own CompoBus/S offers an unsurpassed ease of installation. Fully user-configurable serial and CAN-based communication can be used to emulate a variety of application-specific protocols. EtherNet/IP units provide data link func- tions to share large amounts of data between PLCs. The new PROFINET-IO controller together with the SmartSlice modular I/O system offers Ethernet based I/O with con- troller- and network redundancy.
