Tips & Tricks / Re: A guide to using AdvancedHMI with ABB AC500 via ModbusTCP

« on: October 21, 2016, 03:21:15 PM »

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.

I guess I will try your solution..
It is run mode, I am able to change the variables "On the fly"..
I able to ping to it, but can't make a modbus master (modpoll or AHMI) communicate with the server (slave)..  It keeps going into timeout.

Here is my project for reference: https://www.dropbox.com/sh/ft4p5me182qjcro/AABy2XjI2QukPsN90ZxWgICUa?dl=0

I guess I will try your solution and see if it works, and report back with my newly gained knowledge.

Is this guide still valid.

I've tried this exactly, on the same hardware, but the HMI isn't able to connect to it.
I am able to ping to the IP address.
