Hi

   I have 6 identical machines (S7-300 + TP900 comfort). They are identical programmed. I use TIA v13 SP1. That 6 machines where programmed in TIA v13 SP1 update 5 or 6 (do not remember exactly). I had never had problem like showed in that topic. In one machine I had to add one alarm (algorythm in PLC + message in HMI). But before i downloaded new software I had updated my environment to Update7. After downloading to HMI I have differences in offline and online HMI project. In project I have gauge object which is no longer visible on panel after download. I didn't do changes in that object. I attached screens - please look at it. I tryed to recompile everything, save as new project and nothing. I am afraid to do changes in other machines because of similar problems.

   Please help, thank You.

Hello 

I think you have to upgrade your HMI firmware.

you can make it when you are downloading 

Hi

  If there is possibility to upgrade a firmware then TIA shows that before download to HMI. And in that case TIA do not show anything. However I tryed to download firmware to HMI and that didnt helped too.

   Today I recompiled and downloaded to other HMI its program and everything is ok, so I have problem only in that one machine.

greetings!
