series connection contacts and perform the “AND” operation with the logical operation result obtained. The final result
will be store in the accumulative register.

Explanations:
The ANI instruction is used in the series connection of B contact. The functions are to read out the status of present
designated series connection contacts and perform the “AND” operation with the logical operation result obtained.
The final result will be store in the accumulative register.
Program Example:
Ladder diagram: Instruction code: Operation:
LD X1 Loading in contact A of X1
ANI X0
Connecting to contact B of X0 in series
X0 X1

Explanations:
The OR instruction is used in the parallel connection of A contact. The functions are to read out the status of present
designated parallel connection contacts and perform the “OR” operation with the logical operation result obtained.
The final result will be store in the accumulative register.
