Example: Input contact via NET (here from NET station 3)
The contact of a function block consists of the abbreviated function block
name, the number and the contact function.
Example: Contact of “comparator” function block
How a safety or standard function block is added to the circuit diagram and
parameterized is described in
Section 4.7, “Working with function
If the contact of an Net station is used in the circuit diagram, the NET ID
(address) of the station is placed in front of the contact name,
section , “Wiring a contact or coil of another NET station in the circuit
Example: Contact of a NET station
4.5.2 Changing N/O contacts to N/C contacts
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 ALT. The N/O contact will change to a N/C contact.
▶
Press OK twice to confirm the change.
Change contact

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. Further
information on the diagnostics bits is provided in

DANGER
Persons, systems and machine may be put at risk if an N/C
contact is misinterpreted. When using N/C contacts in the
program of easy800-SWD always evaluate the PRSNT and DIAG
diagnostic bits of this station.
