5. Programming on the device
5.4 Working with contacts and coils
5.4.2 Changing an N/O contact to an N/C contact
DANGER
Persons, systems and machines may be put at risk if an N/C contact
is misinterpreted. When using N/C contacts in the program always
evaluate the PRSNT and DIAG diagnostic bits of this module.
You can define each contact in the circuit diagram as a N/O or N/C.
Switch to Entry mode and move the cursor over the contact name.
Press the ALT button. The N/O contact will change to a N/C contact.
Press the OK button 2 × to confirm the change.

I 03
from N/O to N/C
Bear in mind that the active state of an N/C contact is 0. The 0 state of a contact may,
however, be present if the station is missing or is operating incorrectly. The use of an
N/C contact in the circuit diagram without evaluating the diagnostics bit may cause
incorrect interpretations.
