Declaration of parameters
Missing supply voltage L+
Enabling of the diagnostics, with missing or too little supply voltage L+.
Overflow
Enabling of the diagnostics if the measured value violates the high limit.
Underflow
Enabling of the diagnostics if the measured value violates the low limit.
Wire break
Enabling of the diagnostics if the module has no current flow or the current is too weak for
the measurement at the corresponding configured input or the applied voltage is too low.
Current limit for wire break diagnostics
Threshold for reporting wire breaks. The value can be set to 1.185 mA or 3.6 mA, depending
on the sensor used.
Interference frequency suppression
Suppresses the interference affecting analog input modules that is caused by the frequency
of the AC voltage network used.
The frequency of the AC voltage network can negatively affect the measured value, in
particular when measuring in low voltage ranges and with thermocouples. With this
parameter, the user specifies the line frequency that is predominant in the plant.
