Hello i am trying to make a connection between my arduino uno and plc delta ss2 using rs232 com1 RTU protocol.
The problem here that i did all the steps and programming in arduino and plc and the communication succeed but after a while it stuck and stop to work.
Somtimes after 5 seconds , sometimes after 5 mins, and if i stop the program and run it again it start communicating again.
I attached a picture for the communication part and at the end of the program i reset m1314 and m1315 if they give a signal.
Any ideas??
