Use of logic paths
The user program will be mapped in one or more networks. The networks can contain one or more logic paths on which the binary signals are arranged in the form of boxes.
The following figure shows an example of the use of several logic paths within a network:
Rules
Remember the following rules when using logic paths:
-
Connections are not permitted between logic paths.
-
Only one jump instruction is permissible per network. The positioning rules for jump instructions remain valid.
Executing logic paths
Logic paths are executed from top to bottom and from left to right. This means that the first instruction in the first logic path of the first network is executed first. All instructions of this logic path are then executed. After this come all other logic paths of the first network. The next network is executed only after all logic paths have first been executed.
When jumps are used the regular execution of the logic paths is circumvented and the instruction is executed at the jump destination.
Differences between branches and logic paths
The difference between branches and logic paths is that the logic paths are independent branches that can also stand in a different network. Branches, on the other hand, permit the programming of a parallel connection and have a common preceding logic operation.
