EX-RC1 Remote I/O Adapter
The EX-RC1 interfaces between Unitronics Vision OPLCs and remote I/O Expansion Modules distributed
throughout your system.
The adapter is connected to a PLC via CANbus. Each adapter may be connected to up to 8 I/O Expansion
Modules. The network may comprise up to 60 nodes, including both PLCs and adapters; note that the PLC
must comprise a CANbus port. Communication is via UniCAN, Unitronics’ proprietary CANbus protocol.
The EX-RC1 is run by a factory-installed application. For more information refer to the Remote I/O topics in
the VisiLogic Help system.
The EX-RC1 may either be snap-mounted
on a DIN rail, or screw-mounted onto a
mounting plate.
