The following drawing shows the circuitry of a digital input/output with the varistors for demag-
netization when inductive loads are switched off.
1 Digital output
2 Varistors for demagnetization when inductive loads are turned off
Technical Data of the Configurable Digital Inputs/Outputs
Each of the configurable I/O channels is defined as input or output by the user program. This is
done by interrogating or allocating the corresponding channel.
Parameter
Number of channels per module
Distribution of the channels into groups
