Modifying "SIL Access" level for Variable and Control Modules in AC800M-HI.
As the possibility to change the content of variables in SIL applications in the AC 800M HI is restricted by the “Confirmed Write” and “SIL Access” functionality.
In my case, I have added few Variables and Control Modules in the library level, instantiated the same in Application level and now want to write those from the Graphic. For the same the default "Access Level" property is "Read Only" and I am not able to modify this to "Confirm and Access Enable" as the bottom change bar is greyed out. What may be the reason for this ? [See the attached screenshot].
Are there any specific typical steps to modify "access level" for newly added variable or control module ?
Just for the information, the user has got the "Safety Operator Role" and respective objects are reserved.
Any ideas or solutions are appreciated.
