The '[N]' column indicates two possibilities;
o '0' – presents the open contact (Normally Open). The moment there is a
change from the usual state (closed state), an alarm occurs.
o '1' – presents closed contact (Normally Closed). The moment there is a change
from the usual state (opened state), an alarm occurs.
Fig. 49 serves as an example of a digital input program. The programmed line No.1 is
set as normally closed for the house door. The message for this program is “door
opened”. If the door opens, the dry contact is disconnected and changes from 1 to 0.
