I read the FAQ, did not mean much to me. They give no example. The answer is not for a person like myself. I see what they are saying, but they do not tell how to use it. This is the problem I see with many help files. They give lots of info, but do not say how to use it.
In any case, I have both set to 19200 , stopbit=1, databit=8, odd parity. I tried setting the EBC to both slave and master. I also tried the AD modbus and Modicon Modbus. In all cases I get the "Comm port timeout". Now it is becoming a challenge. I hate to give up until I get it to work. I made a simple push button to turn on the first "Y", if that is wrong, will that give me the time out error?
