Notes
Note
The value of the analog module inputs is in S7 format.
Note
The inputs of the analog module are passive inputs, i.e. to configure an analog input circuit,
each input will require an additional, isolated external current source connected in series. If
the output of the analog module is not being used by another application, it can also be used
as a current source for an analog module input circuit. The "Start value of value range" and
the "End value of value range" of the analog module output have to be set to 65535 for this.
Thus, the maximum possible current will always be available via the analog module output.
