Can I change some settings to make PROFIBUS DP communication more reliable?

YES, in the busparameters of the master you can change some settings to make the communication more reliable: Retries/Repeats = 5 Tqui = 9 MinTSDR = 22 more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
