Use RS485/RS232 to create a multi-device network. Establish master-slave communications among Vision OPLC™ units and any connected device that supports the MODBUS protocol. Any Vision OPLC™ in the network may function as either master or salve.

Integrate up to 63 units of Vision OPLC™ and M90/M91 OPLC™ units into an efficient high-speed network. Use the M90/M91 as a smart remote I/O.

Use RS232 to gain PC access to your Vision OPLC™ network. Unitronics OPC/DDE server enables the Vision OPLC™ to exchange data with any Windows-based application.

The “Protocols” FB enables Vision OPLC™ to communicate with a broad variety of external devices, such as bar-code readers, printers and servos.
