OR
The OR instruction takes the logical OR of the value of a specified BOOL variable and the execution
condition and outputs it to the next instruction. Use the OR instruction for a NO bit connected in parallel
with the previous instruction. Use the OR instruction to configure a logical OR between an NO bit and
one of the following: a LD or LDN instruction connected directly to the bus bar, or the logic block starting
with a LD or LDN instruction and ending with the instruction immediately before the OR instruction.
ORN
The ORN instruction takes the logical OR of the inverse of the value of a specified BOOL variable and
the execution condition and outputs it to the next instruction. Use the ORN instruction for a NC bit con-
nected in parallel with the previous instruction. Use the ORN instruction to configure a logical OR
between an NC bit and one of the following: a LD or LDN instruction connected directly to the bus bar,
or the logic block starting with a LD or LDN instruction and ending with the instruction immediately
before the ORN instruction.
The following figure shows a programming example of the OR instruction. It takes the logical OR of vari-
able A and variable B and outputs it to variable C.
OR: Takes the logical OR of the value of a BOOL variable and the execution condition.
ORN: Takes the logical OR of the inverse of the value of a BOOL variable and the execution condi-
tion.
