Hi,

You can use a Datablock where you have the old value and then compare it with the new value. When there is a differnce bigger then you want then you may switch a Merker or Output or a Databit in the same Datablock.

Hi,

You may make a source of the example, then somebody else can do something with it without typing the hole example over....

TIP: In the editor you may choose in the STL/FUP/LAD editor "File" --> "Generate Source..." and then generate the source by given it a name and choose the blocks that will be necesary. This source you can find in the source-container of the program, there you can export it to a .AWL file.
