9.6.1 Four (two) analog inputs for resistance tests − EPM−S404
During the execution time you can access the parameter data via the following data sets:

further process alarm during a process alarm processing.

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. As soon as the
measured value is outside a limit value and limit value
monitoring is activated, a process alarm is triggered.
