Technical data of the configurable digital inputs/outputs
Each of the configurable digital I/O channels can be 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 DC16...DC23 Terminals 4.0...4.7
If the channels are used as outputs
Channels DC16...DC23 Terminals 4.0...4.7
Indication of the input/output signals 1 yellow LED per channel, the LED is ON when
the input/output signal is high (signal 1)
