Example: Resetting outputs and markers
All outputs and markers that you have used can be reset to
0 with one command.
A rising edge at the coil of Z3 will cause all Q and S outputs
and all M and N markers to be reset.
The values in the logic table have the following meanings
For switching 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
Negation (contact)
Negation means that the contact opens rather than closes
when it is actuated (NOT circuit).
In the CL circuit diagram, press the ALT button to toggle
contact I1 between n/c and n/o contact.
