Default
The OMRON D40A or D40Z Non-contact Switch performs diagnosis using the
safety input terminals, and so the value is input to the function block after eval-
uation. Therefore, the Non-contact Door Switch Monitoring function block
judges whether the values for Input 1 and Input 2 are the same. In other
words, operation is the same as for the AND function block.

The Safety Mat function Switch function block monitors the status of an
OMRON UM Safety Mat.
Default
The OMRON UM Safety Mat performs diagnosis using the safety input termi-
nals, and so the value is input to the function block after evaluation. Therefore,
the Safety Mat Monitoring function block judges whether the values for Input 1
and Input 2 are the same. In other words, operation is the same as for the
AND function block.
