5.16.2 AND compare
(FNC 232 to 238)
Operation:
The value of S
1
and S
2
are tested accordin
g
to the comparison of the instruction. If the
comparison is true then the AND contact is active. If the comparison is false then the AND
contact is not active.
Points to note:
The AND comparison functions can be placed an
y
where in a pro
g
ram that a standard AND
instruction can be placed. I.e., it is a serial connection contact.
