Note
If a Pt100 element is accidentally not connected in this operating mode and an input voltage
higher than 0.25 V is output, the analog module automatically switches to the "no operating
mode" operating mode and resets the gain factor to "1". This is signalized in Status Word 0
(channel-specific) in the input image. In addition, a corresponding error code is output in the
diagnostics slot at a counter value of "2".
In the case of operation without a Pt100 element, a slightly negative voltage may be applied,
which results in an error status for the module. Here, the "PNFault" LED and the status byte
1 are to be observed.
