System bus interface with RS-232/RS-485 cable converters
(for two-wire and four-wire bus)
To operate the controller in combination with cable converters, a constant bus connection is
required (data cable). 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
126 devices (two-wire bus) can be connected to such a segment.
