I work on an automation project for a long time. everything worked fine until I installed today industrial data bridge to archive my variables. Now when I run the runtime I have exclamation mark everywhere (see the attached images). I uninstalled industrial data bridge but the problem is still there.

please help me.

excuse my english im not a native english.

Hello marotaro,

the yellow triangle with the exclamation mark means that the HMI has lost the connection to the PLC.

Please check your PG/PC Interface in Windows (Start > Control Panel (View by: Small Icons) > Set PG/PC Interface.

Make sure "S7ONLINE (STEP 7) --> " is connected to the correct network card, not "PLCSIM" or another false Network.

Can you ping the PLC from the Operator Station?

What WinCC RT is it? WinCC RT Professional? Which Version/Service pack/Update?

Here is the link to an FAQ about WinCC RT Professional and the IDB, but I don't think it can help much in your case. But maybe?

Can you ping the PLC from the Operator Station? 

 No I can't i'm just working on simulation by PLCSIM.

Please check your PG/PC Interface in Windows (Start > Control Panel (View by: Small Icons) > Set PG/PC Interface 

 See in the attachment what i've configured there.

Like I said before all was working fine until I installed the IDB.
