ANB,ORB

Association Instructions

Ladder block series connection and parallel connection 

(ANB,ORB)

ANB,ORB

Function

(1) Performs an AND operation on block A and block B, and takes the resulting value as the 

operation result.

(2) The symbol for ANB is not the contact symbol, but rather is the connection symbol.
(3) When programming in the list mode, up to 15 ANB instructions (16 blocks) can be written 

consecutively.

(1) Conducts an OR operation on Block A and Block B, and takes the resulting value as the 

operation result.

(2) ORB is used to perform parallel connections for ladder blocks with two or more contacts.

For ladder blocks with only one contact, use OR or ORI; there is no need for ORB in such 

cases.

(3) The ORB symbol is not the contact symbol, but rather is the connection symbol.
(4) When programming in the list mode, it is possible to use up to 15 ORB instructions 

successively (16 blocks).
