Digital I/O X State shows the state of the digital I/O in question. All I/O use IEC61131-2 logic levels. As default the inputs use positive logic, and so the
state parameter is 0 if the digital I/O is low or 1 if the digital I/O is high. Digital I/O Logic Polarity (Pr S.01.008) can be set to Negative Logic (0) to
change the logic for Digital I/O 1-8, so that the state parameter is 0 if the digital I/O is high and 1 if the digital I/O is low.
The state parameter represents the digital I/O state whether it is configured as an input or as an output. If the digital I/O is configured as an output to
be controlled using the Digital I/O Register (Pr S.01.007), then the state parameter will still show the state of the output even though the source is
zero.
For Relay 1 and 2, the state parameter is 0 if the relay contact is open, the state parameter is 1 if the relay contact is closed.
