5.17.2 AND compare
(FNC 232 to 238)
Operation:
The value of S
1 and S2 are tested according 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 anywhere in a program that a standard AND
instruction can be placed. i.e., it is a serial connection contact.
(See page 2-6 for AND instruction)
