9.2 Controller with serial RS-485 interface
A constant bus connection is required (data cable) for the operation of the controller with serial
RS-485 interface. The bus line links the control units/devices in an open ring. At the end of the
bus line, the data cable is connected to the control station using an RS-485/RS-232 converter
(e.g. TROVIS 5484).
The maximum range of the bus connection (cable length) is 1,200 meters. A maximum of
32 devices can be connected to such a segment.
