8.5.4 RS-485/USB interface
board
To integrate the controller into a
communications network, the controller can
be fitted with an optional RS-485/USB
interface board (see Annex B). The USB
connection can be used to transfer data
using TROVIS-VIEW.
The RS-485/USB interface board includes
one of the following interfaces:
− RS-485 interface (4 terminals)
− USB interface (5-pin mini-B port) (slave)
The RS-485 data transfer uses an SSP or
Modbus RTU protocol. Slide switches are
used to set the two-/four-wire operation and
to activate bus termination.
The protocol and the parameters of the RS-
485 interface is set at the controller in the
D.3.1 configuration item.
