4.14 Basic circuits
The values in the logic table have the following meanings
For switch contacts:
•
0 = N/O contact open, N/C contact closed
•
1 = N/O contact closed, N/C contact open
For Q…: relay coils
•
0 = coil not energized
•
1 = coil energized
4.14.1 Negation (contact)
Negation means that the contact opens rather than closes when it is
actuated (NOT circuit).
In the easy circuit diagram, press the
ALT
button to toggle contact I1
between N/C and N/O contact.
Table 16:
Negation
4.14.2 Negation (coil)
Negation means in this case that the coil opens when the N/O contact is
actuated (NOT circuit).
In the easy circuit diagram example, you only change the coil function
Table 17:
Negation
4.14.3 Permanent contact
To energize a relay coil continuously, make a connection of all contact fields
from the coil to the leftmost position.
