Limits with the "Fixed value" data formats
The following diagram shows an example of the data format
"VZ + 12 bits right-justified" with the scaling end values:
– Lower limit = 500
– Upper limit = 3500
The principle of the limits also applies to the data formats
"VZ + 15 bits left-justified" and "VZ + 12 bits left-justified".

Wire break/open loop monitoring can be activated by means
of appropriate parameterisation for the signal range
0/ 4 ... 20 mA. The messages are made available as diagnos-
tic information (see section 8.5.1).
