Hi John, you really understood my situation. I appreciate. I've been reading some materials but honestly, they are not hitting the nail on the Head. If I can see a sample, my life will not remain same. Lots of challenges at hand running co-currently in my head right now and at the office. I will appreciate.I understand where you are coming from Dan. How to begin.
I have read all the links (many I have seen before) and I understand much better now how Modbus is supposed to work. The fundamentals.
But if I had to sit down and write out a Modbus program, I wouldn't know where to start. Big grey area there. I can write program don't get me wrong, 5000, 500, Idec, National instruments. You get the idea. But I don't know how to write out Modbus. That being said someone will come along and say "It's the same as........." and we will of course feel like Derp's
I have to write a program in the fall that will communicate with a burner control, along with all the warnings, failure notices, ect. In Modbus with a PLC and HMI
I have been trying to figure out how to put into a program for about three weeks now as side work, but I am completely clueless on what the program would look like.
So Dan, I feel ya. and if I figure it out, I send you my notes and some code to get started.
Regards
