hi guys
this is my first project using Siemens HMI, I got a problem to setup comunication between AB PLC and HMI, when the HMI is in the run mode, the system alarm show me that the HMI had already connected to PLC, but when I try to push one of the button on the screen, the status of the tag linked with this button in PLC did not change. I just want to know how to configure the tag in comfort HMI, link to the tag address in PLC? link to alias tag name of PLC?
thanks
