5.17.3 OR compare
(FNC 240 to 246)
Operation:
The value of S
1 and S2 are tested according to the comparison of the instruction. If the
comparison is true then the OR contact is active. If the comparison is false then the OR contact
is not active.
Points to note:
The OR comparison functions can be placed anywhere in a program that a standard OR
instruction can be placed. i.e., it is a parallel connection contact.
(See page 2-7 for OR instruction)
