AND function
Fig. 4.5.4 l) Output programming window with AND option
With the OR function, to activate the output programmed in this way, all that is needed is
one of the events associated with the output and present in the Associated Sensors
list.
On the other hand, if you want to condition the activation of the output to the
contemporaneous presence of more than one of the selected events (AND function),
use the "AND" option. By clicking on the "AND" option, a setting window will appear
where you must insert the number of events that must occur at the same time to activate
the output that you are programming. E.g. by inserting 2, 2 of the Associated Sensors
must be present at the same time to activate the output. A maximum number of 6 events
can be inserted.
If "Fault seen as Alarm" is checked, any of the channels in Fault will be considered as
being in Alarm.
Output operating mode
There are 3 different operating modes of the output. Click on "Operating mode".
