Configure I/O
Universal Channels
Universal Channels are flexible connections that can be configured either as Inputs or Outputs with many
different types of signals available to be configured.
Check the following table to have an overview of all the possible configurations.
Please refer to the
column “Max per device” to know the configuration limit
s of each device
