Welcome to the forum, I think you would be best to post this in the main Q&A, however, a few questions. It says must be on for 50ms but it also says can go on/off between those times, this does not make real sense. if it is on for 50ms and off for 100ms no problem but like the drawing the second pulse is switching on/off multiple time is this going to be classed as an on pulse ?.
I think there is room for clarity, for example:
50ms pulse is classed as a count and a multiple pulse within 50ms is also classed as 1 count, or is the second multiple pulse not counted because it is not on for a min of 50ms.
Clever way to ask for homework help.
yeah, pushed my buttons rather efficiently.
At least you didn't give them the right answer
Done
This is the correct answer.
What is this obsession with ladder logic anyway?
I get that IL translates well to LAD, but really can’t see the point of ladder in 2020? As soon as you process anything other than bits, the ladder becomes obsolete?
Have you heard of FBD or ST?
Also...we may have rolled over to 2021 now. I think it happened back around January.
