Menu 2 - Digital I/O
Menu 2 on the module controls and displays all parameters associated with the Digital I/O.
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.
A value of Off (0) or On (1) in Digital I/O X Invert allows the I/O state to be non-inverted or inverted as required.
The Digital I/O X Source / Destination parameters provide the routing for the source and/or destination for the digital I/O.Relay X Source provides the
routing for the source of the two relays.
