ViS-A controllers has RS-485 bus for connecting devices that can operate using the Modbus protocol in the baudrate range from 9600 to 115200 bps. All signals are galvanically isolated from the main controller circuit (high speed digital isolators are used). With RS-485 network possible to increase the total number of inputs/outputs up to 240 (plus inputs/outputs on the CNC controller board).

Both devices produced by ViS company (ViS-IN8, ViS-OUT8) and devices from third-party manufacturers (for example, spindle motor inverters) can be used as devices operating as part of the RS-485 network.
