The Controller Link is an FA network that can send and receive large amounts of data easily and at high speed. The Controller Link supports data links that enable sharing data between PLCs and computers and a message service that enables sending and receiving data whenever required. Systems can be flexibly built by using repeater units to
enable T-branches, long-distance wiring, and converting part of the network to optical cable.

Large-capacity data links are easily achieved without programming simply by setting data link tables
Up to 20,000 send/receive words can be set per node for units (up to 62,000 words for boards)
Data links can be performed with up to 4,000 words per node while ensuring data concurrency
User-set data link tables can be changed while data links are operating
Errors for the entire system can be monitored by using error diagnosis support software and a variety of status flags

Omron CJ1M CPU's, PSU's and Expansion Control/Interface Modules

The CJ1M is a powerful and compact PLC family, covering applications requiring up to 640 I/O. CPU models are available with built in pulse outputs for stepper or servo control, and all CPUs in the CJ1M family enjoy optional modules for many types of I/O and communications. The CJ1M is the next generation of PLC from the earlier CQM1 series, and program compatibility eases migration between them.As with other Omron PLCs, the CJ1M series is programmed with CX-Programmer (RS stock no. 400-6440), designed for compliance with IEC61131-3. The backplane-less construction of the CJ1M series makes selection and installation simple; choose the CPU and power supply unit, then the I/O modules to suit the application. These items are simply plugged together end to end and then mounted on DIN rail.
