6 posts in this topic

Guys, 

What is HMI Tag group that can be added under the HMI tags in the Project Tree? I am new with siemens and trying to debug an HMI. The error is " ,The parameter of a function is not available for trigger 507 - Analog Edit, event 'Loaded'. The referenced object does not exist.,,,". There is a weird event set up upon loading of the screen which is causing error. Thank you in advance. Please guide me.

Hi:

You can find some "How to's" abput the HMI connection in TIA Portal in this link: http://www.tecnoplc.com/conexion-hmi-para-compartir-variables/ . Here they explain how to connect the HMI tags with the PLC variables.

there are more other articles that define the HMI variables you want to configure... Have a look http://www.tecnoplc.com/agregar-pantalla-hmi-al-proyecto/ because you will find information about How to do it...

I hope you could find your answer there...

When do you get this error? When you are compiling the HMI code? Or during operation of the HMI?

Thanks TecnoPLC and pop29684 you were very helpful.

I was getting the error during compilation. After doing some more research i found the event was pointed to a script which wasn't copied when the screen was copied from another project. And that was the reason of an error.

Hi HatePLC:

Good work... that was a difficult error to find the solution... But you have worked hard...

How do you found the error inside the script??? during the compilation of the program?? or how to???

I was always suspicious about the event that was being called. I went through all the possible events inside Siemens, but I couldn't find any similar to which I had. Than I arranged the source project and started comparing every inch and meter and TADAAAA.......
