By selecting one of the above items, you may set the Logical I/O property as
described above.
Forces
Physical I/O points may be forced to be On or to be Off. An I/O point thus set will
be permanently set to that state overriding all other conditions. For example, if a
Logical output is mapped to a Physical output and the Physical output is forced to
be On, the physical state of the output will be on (“energized”), but the Logical
output is unaffected and may be On or Off depending on the process or other
conditions.
However, if a Physical input is mapped to a Logical input and the Physical input is
forced On, then the resulting Logical input will also be turned On. Likewise if a
Physical input is forced Off, then it will be off and all Logical inputs mapped to it will
be off, regardless of the physical state of the Physical input.
Any Physical I/O point that is forced On or Off will remain so until reset with this
menu.
If you select “Forces” you will be presented with the following menu:
