Master, what do the suffixes AO, AC, and PV after the rank in this system mean? What are their functions, and in what situations are they used? How do I use it? To worship
And under what circumstances should the EN and ENO of the module be connected?
You do this in the ladder diagram; only when EN is activated does the module start to function!
You should check the algorithm help documentation for this!
In the ladder diagram, connect EN; if there is no ENO module later on, no connection is required. In FDB, you can double-click on a module to disable EN and ENO, yet the module will continue to execute.
Thank you, expert. Take a look – this one is also within an LD paragraph. Why is there a connection between EN and ENO in one case, while there’s no such connection in the other? What are the implications of being connected or not?
No impact, it’s not connected; EN remains ON at all times. It is recommended to connect them.
