3. In the case of the element from the second step (interim result), the compiler conducts
the output current to all elements directly connected to it. Then it evaluates the next
element. Finally, it returns to the second step until all elements are evaluated or no
element is available for the evaluation.
4. The processing procedure is interrupted or ended.
You will find program examples for the processing order in FPWIN Pro in the online help
(keyword “Processing Order in LD and FBD Networks”).
9.10.3 Subdividing Networks
We recommend placing each program string in its own network. This has the following
advantages:
•
Networks are small and easy to see
•
You can find errors faster, e.g. by deactivating networks (see page 73)
•
Unintentional use of "late assignment (see page 121)" when accessing variables is
avoided.
The top part of the illustration contains two strings in a network. When compiling or checking,
you will receive a warning message in such a case.
Practical subdivision of networks
However FPWIN Pro deals with Network 1 the same way as the two strings arranged behind
each other, as illustrated in the bottom part of the diagram.
