Single- or Two-Channel Use of Analog Inputs
The analog inputs of the F I/O module can be used with one or two-channel
evaluation.
The settings are made via the “Sensor Evaluation” parameter, which is described
in Section “Commissioning” > … > “Setting Parameters”.
Using two-channel evaluation for analog inputs, the input measurements of the
two inputs are compared. The following parameters must also be set:
•
Tolerance windows
•
Discrepancy time
•
Relative tolerance and/or
•
Absolute tolerance
For two-channel use, ensure that the channel parameters match!
When using two-channel evaluation for analog inputs, make sure that the
channel parameters of both inputs are configured identically!
