During the execution time you can access the parameter data via the following data sets:

2, 3 Upper limit value
channel 1 You can define an upper or lower limit value for each
channel. For this you can only specify values from the
nominal range, otherwise you’ll receive a
parameterisation error. By specification of 7FFF
h
for the
upper or 8000
h
for the lower limit value, the
corresponding limit value is deactivated.
If the measured value is outside a limit value and the limit
value monitoring is activated, a process alarm is triggered.
