The running logic SFCs for DUMP and CHG_COLOR are shown in the following diagrams. If you are viewing this book online, you might want to print these pages. Then you can put the pages next to each other and see how the phases communicate at different steps. The coordinated messages will have the same message IDs (the last two digits): a 5201 pairs with a 5501; a 5202 pairs with a 5502; and so on. In addition, note that the request to acquire the color header (4015, where 15 is the equipment ID) is later followed by a request to release the resource when it is no longer needed (4215). To make it easier to configure, we have shown the text for the actions and the transition expressions on the illustration.
For the sake of brevity, in many of the examples in this tutorial, we only configure the running logic. However, in a real system, you need to carefully consider which active states you will use and then configure the logic for those active states, as well as for the Failure_Monitor.
Before configuring CHG_COLOR, you will add a parameter to the running logic to record the initial level in the blender.
