The operator must first decide if the list of conditions must be evaluated as AND (all must be
checked) or as OR (it is enough that one condition is met).
You cannot have mixed AND/OR
logics (this can be done using digital virtual inputs; see below).
You can add up to 30 conditions. Each condition can be reversed individually: in the previous
figure, for instance, the controller will check that the digital input 3 and the digital output 8 are
both
inactive . The following conditions can be added:
•
DI_XXX: logic states of all the digital inputs (physical or virtual).
•
DO_XXX: logic states of all the digital outputs.
•
AL_XXX: warnings/locks present.
•
ST_XXX: internal states of the controller.
•
AT_XXX: states concerning the thresholds on analogue measures (see par. 5.6.2).
The following table shows the list of the internal states available for the AND/OR logics.
