Byte 1: State of digital inputs/outputs
The Stat_Qx status bits indicate the outputs' state. This means that if out-
puts have been configured as "retentive," the outputs' state can be identified
in the user program after communications are restored or when the PLC
starts.
2.9.7.2 Outputs
Byte 0: outputs
The way the outputs are driven will depend on the selected configuration.
Output configured as retentive:
Driving will be based on a 2-bit combination for setting and resetting.

This is the logical driving state.
If an output is being driven but is switched off by the output
stage due to a short-circuit / overload situation, or if the 24 V
power for the outputs is missing, a "1" will still be returned.
