Notice
Connection Behavior
The ORB block parallel connection behaves as follows:
- An OR operation is performed on block A and block B and uses the new result as a new execution condition.
- ORB performs parallel connections of circuit blocks with two or more contacts.
- Use OR (Open Contact or Rising Edge Contact) or ORI (Closed Contact or Falling Edge Contact) for circuit blocks with single contacts.
- ORB is not required to circuit blocks with a single contact.
- ORB is not a contact signal.
- ORB is a connection signal.
- In the Instruction List (IL) mode, ORB can be written consecutively up to 15 connections (16 blocks).
- If more ORB connections are written consecutively, the operation may not be performed properly.
ORB refers to the bus bar connection between the two blocks vertically.
