DR45 Protocol request

The protocol ID of the log to be displayed in data record 46 is entered here.
The protocol ID to be read is also used for the calibratable reading of the log via SecureDisplay.
For example, if ID 129 is to be displayed, the value 129 must be entered in DR45 and sent to
SIWAREX. The log with ID 129 can then be read from DR 46 and displayed in a calibratable
manner in SecureDisplay using command 891.
If the protocol ID to be read in DR 45 is 0, data record DR 46 is automatically written with the
last created log. Thus, after a dosing, DR 46 can be read directly into the PLC for further
processing without having to request the last log beforehand.
