Logic diagram ‘OR-NAND’ gate problem

2021-07-22View Original

Thread Content

Gentlemen, I would like to learn *logic diagramming methods systematically; I already know about AND/OR, RS flip-flops, and so on. But based on the functional description (control requirements) derived from the process, how should I draw it? Are there any textbooks or tutorials available? Thank you all for your overwhelming intelligence

The best way is to find a logic diagram and just follow its example

A train runs fast thanks to its engine; find a master to learn from.

There are many logic diagrams and process descriptions available, but I have no idea where to start drawing them:(

Can a big shot be a master? {:1_90:}

I suggest you don’t bother thinking about how to do it, because what you come up with might make logical sense, but it’s not that simple in practice. Go to DCS or SIS, look at the existing logic to understand it fully before thinking of anything else; if you can’t understand it, it means your foundation is weak

Since the logic diagram is available, if you understand it, you just need to draw it following that diagram. The logic may be different, but all the legends and such are still there, right? First, outline the logic behind your manufacturing requirements, and then convert that logic into drawings

I’ve learned it – once you dive into chemical engineering, it’s like entering an endless ocean!
