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 Value
Number of channels per module 8 inputs/outputs (with transistors)
Distribution of the channels into groups 1 group for 8 channels
If the channels are used as inputs
Channels DC0...DC07 Terminals 2.0...2.7
If the channels are used as outputs
Channels DC0...DC07 Terminals 2.0...2.7
