Association Instructions
Ladder block series/parallel connection
ANB, ORB
• ANB: Ladder block series connection
This instruction performs an AND operation between block A and block B.
• ORB: Ladder block parallel connection
This instruction performs an OR operation between block A and block B.

Execution condition
Processing details
■
ANB
• This instruction performs an AND operation between block A and block B, and outputs the operation result.
• The symbol of the ANB instruction is not a contact but a connection.
■
ORB
• This instruction performs an OR operation between block A and block B, and outputs the operation result.
• Ladder blocks, each having two or more contacts, are connected in parallel. Use the OR or ORI instruction for connection
of blocks, each having only one contact. The ORB instruction is not required in this case.
• The symbol of the ORB instruction is not a contact but a connection.
