Hello everyone,

I have a fault on my HMI screen, the fault is 190011: tag could not be written in to the PLC. 

The connection between the PLC is build and the security settings are set to full access. The strange thing is that when i use an another computer and downgrade the firmware on the HMI this works.

The loaded firmware on my computer is V17.00.00.07_05.01

 Is there a solution for this problem or do i need to reinstall something? 

The used hardware for this is a CPU1511-1PN and HMI TP1500 comfort V2

Best Regards 

Gianni

Hi Gianni.ESD,

If the addresses are correct and the S7-1200 security allows access to all the variables, the first thing I would recommend would be to regenerate the project by deleting the IM folder and compiling again ("How do I delete the IM folder of my TIA Portal project?") and/or regenerate the tags in the project.

Best regards!

Thank you this was helpful, the problem is solved.
