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
controller 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 functions 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 controller- and network redundancy.
