Good evening, Ladies and Gentlemen,
First of all, let me say, that I am personally and, as I believe, lots of other people are extremely grateful for everything that you are doing and it is truly super significant to have such resource as RealPars.
What is more, I simply want to say my gratitude for such cources as that one connected with basics of SQL programming. I may assume, that currently it is not so popular(I have made such assumption, judging from amount of views on Youtube), but I consider such cources to be really very helpful, To be honest, I have not watched this course yet as well, but I am planning to do this in the nearest future, so you may expect overall views to be increased, at least for 1 point))).
Furthermore, I sincerely hope to have more of such types of courses and continuing of SQL course for more sophisticated level, in particular and generally to have such courses, that are more connected with like general programming or high level programming(application development) or how to call it correctly. They are extremely valuable, from my personal point of view.
So, please excuse me for such a long opening, I just wanna show my sincere support.
Actually, my question is the following: could you please suggest any specific literature or some other resources for advanced PLC programming and HMI development. What I mean is that, there are a lot of principles and paradigms for object-oriented programming and apllication development for Windows and mobile, but do we have such paradigms, concepts and methods for automation?
So, for instance, all of us as engineers know that we are obliged to create some blocks in program for processing of alarms, to create or to have some organization blocks for I/O errors, to create possibility for mode changing(automatic/manual) and so on. But I am interested whether we have a general concept for sustainable and qualitive development of automation program and HMI interface(so, whether it is better to create such types of blocks, to build our logic inside of the block in specific way, which moments we should pay attention to, generally how architecture of the program should be built).
I am aware of ISA 88 and ISA 95, possibly you may advise some other fundamental standards or something like that. So one more time, any literature on this topic, possibly your personal professional experience, any forums or communities, where I may find out this information. I would be extremely grateful, possibly, for any personal contacts to discuss such topic.
Thank you so much for time and consideration in advance.
