As a standard, the multimode COM user interface is delivered as an
RS232 interface. The parameters for RS422/RS485 operation are set by
programming the OPEN_COM standard PLC function block and by
assigning the COM FB input correspondingly. More detailed information
can be found in the PLC programming instructions (DOK-CONTRL-
WINPCL*_VRS*-AW0_-EN-P).
The BT bus can be used to connect up to four operator terminals of type
BTM15/16 or BTA20. The total maximum length of the BT bus may be up
to 50 m. This applies both to the connection of only one device and to the
connection of the permissible maximum number of 4 devices. It is not
possible to quickly access the I/O data of the operator terminals from the
PLC (e.g. %IBP*.*).
The address assignments required for programming can be found in the
respective documents of the devices to be connected.
