3. Analogue input module CPX−4AE−I
Channel parameters: Lower limit channel x / Upper limit channel x
Remark If the input value is less than the parametrized lower limit or exceeds the parame
trized upper limit, an appropriate fault is displayed (providing the
relevant channel parameter Monitoring channel x monitoring lower limit" or
Monitoring channel x monitoring upper limit" is active).
The upper limit must always be more than the lower limit.
Modifications to the limits must be made in steps of 16 bits.
Permitted limits:
The limits are checked for validity during parametrizing. Invalid parametrizings
are not accepted the module uses the previous (last valid) parametrizings.
The permitted values depend on the parametrized data format (see section
3.4.5). If the module parameter Monitoring parametrizing faults" as well as the
relevant channel parameter Monitoring parametrizing faults" is set to active",
the relevant fault will be displayed.
