The purpose of the digital inputs is to run the system, trigger alarms, protect the system, change settings, and others. A
digital input may have several fields such as Name, Active if, Status, Delay, etc.
Name: if the name is displayed, the digital input is enabled. When disabled, the actions related to the input will not be taken.
Active if: OPEN or CLOSED can be set. It allows to set the input for both, normally open or normally closed switches.
Status: digital input status, CLOSED or OPEN. When the status is the same than the "Active if" condition (means the input
is active), the actions for the input are taken.
Delay: the actions for the input will be taken when the input status has been the same than the "Active if" condition during
the time set by "Delay".
