Hello. Search for the file "C:\KRC\SmartHMI\SmartHMI.exe.Standard". In this file all the HMI is defined. Then in this file search for line "<SoftkeyBar SystemName="SKB_STOP_NORMAL" Aliases="SKB_STOP_PARENT, SKB_STOP_CHILD, SKB_STOP_FOLD">" and under this line there will be buttons defined like button 1, button 2, ... search for button 5 and add the parameter Right="UM20" at the end of the line.
"<Button Position="5" DBKey="TPBaseTouch" ProcID="2500" ModuleIdent="INLINEFORM" ProcParam="0" Right="UM20"/>. Now you have defined user level to that button. So when operator will be logged in the touchup wil be disabled, when Expert user will log on the Touchup button will be active. Then do a cold boot with reload files.You can use this approach for other buttons like for delete, new, ...
I haven't tested yet what happens if technology package like arctech or any other is installed which adds the lines into this file(does the lock stays or not).
Thank you. I was searching for same solution.
