About Networks

You can create a decentralized control network of up to 63 controllers using CANbus. This is sometimes called a multi-master network. In such a network, CANbus enables inter-PLC data exchange. Technical specifications and wiring diagrams are given in the User Guide. Vision controllers also support data exchange via the MODBUS protocol

.

You can network M90 Micro-OPLCs and Vision OPLC controllers.

RS485 is a balanced serial interface for the transmission of digital data, which enables you to create a multi-drop network containing up to 32 devices, or nodes.

You can access a networked controller unit via its RS232/RS485 port using a PC, whether directly connected or via modem link. Using any networked controller as a bridge, you can view, read, and write data into any unit, as well as upload and download programs.

This feature can also allow you to view your network via a SCADA program.
