A guide to using AdvancedHMI with ABB AC500 via ModbusTCP

<< < (2/2)

Friedrich:
Gave your program a try with the %M instead of the %R that I used. It worked as well, so your problem is most likely what you do in AdvancedHMI.
Here's the one I made, try it: https://www.dropbox.com/s/036xh2g8376cer8/AdvancedHMI%20389r.zip?dl=0

I solved my issue..
The problem was in codesys, you are able to define the port of the server in there, but somehow is that port you set not the one used for modbus, I was able to ping the ip adress with the given port number with telnet without any problems.
I tried different ports and ended up having a connection established on port 502 which incidentally is also set as the standard for modbus..

I am still confused on what codesys is doing using 1200 (the other port number).. but hey it works..

thanks for your help -  And sorry for questioning the validity of your guide.  It still works.
