The PLC ready contact is a relay contact which is closed via a hardware
watchdog. It is permanently triggered by the running PLC program. In
case of an error (hardware error, firmware error, system error, etc.), the
contact is mandatorily opened. The PLC ready contact can, for instance,
be wired in the emergency-stop chain of the machine.
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
(DOK-CONTRL-WinPCL*4VRS).
The BT bus can be used to connect up to four operator terminals of type
BTM15/16 or BTA20. The maximum length of the BT bus from the
connection point to the last user 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*.*). Data is
exclusively exchanged via the core image storage.
The address assignments required for programming can be found in the
respective documents of the devices to be connected.
