Function
ANB
(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.
ORB
(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.
