Override Auto Lock for specific objects
We are running 800xA 5.1 FP4 on 3 AC450 controllers. I would like to over ride the auto lock on a select few valves to require another action before they can be opened. (They must select and lock the object before they have any dialog with it) I would prefer to to this without changing the security definitions for these objects. Since it's only a handfull of objects, is there a way to add another required action?
Thanks in advance,

800xA for Advant Master uses a legacy lock function (not the Lock Server in 800xA). It does not matter if Auto Lock is enabled or not, any operation from the faceplate will cause the lock to be taken momentarily during the operation. As far as I know, Auto Lock can not be configured on object level, only system level.
But if you on the Control Connection aspect for the few objects you want to add extra protection to, set the "Confirmed Write" flag on the OPC property/properties used to control the object, an extra dialog will be presented to the user which he need to confirm or reject.
You could temporarily turn on AuditEvent_Operator action to see what property the faceplate is manipulating.
Setting Confirmed Write on a MB300 AI's UPD_BLK property (Block Input) will result in this behavior when blocking/deblocking:
