Information
If a fieldbus module is configured, virtual inputs cannot be activated via the
integrated interface. In this case the request will be rejected by the PNOZ-
multi with error message 0x63 (request cannot be executed).
Control Byte (Byte 40)
Bits 0 … 2 of the Control Byte contain a watchdog function.
If no virtual inputs are sent by a communications partner within the defined watchdog time
(watchdog timeout), the PNOZmulti sets the virtual inputs to "0".

Information
The watchdog functions of the requests 0x14 segment 0x02 and 0x53 use
the same watchdog timer. In other words, the watchdog timer is reset if ei-
ther request is called.
