Thanks Saragani. Yes ,i see someone program will have a green line state that online mode. Although i without the green line, i still able to upload my latest program into the Touchscreen, but this issue will come back with online display exceed, if i disconnect the online button in software and connect online back ,it will pop"online mode was terminated due to communication error,please check connecting cable" (FYI,i already try 3pcs Ethernet cable,same issue. and for USB,laptop unable to search the touch screen )

Im not really understand the meaning. Does it mean too many/over data tag assign in this PLC (US10-B10) or the name of the data tag is too long?

Now i totally open a new project and only draw a valve , but still have the same issue. Is that possible i choose wrong PLC protocols communications? (From HMI communicate to PLC only) test.ulpr

Hello Mr Joe, Here is the example i doing now. Actually there will be additional custom control will be added later. Example.ulpr

Dear All, i found this error during after finish HMI drawing. Is there anyone know the causing reason? All my tags is under Global scope.
