LEG (Load-Evaluate-Go) with AC800HI Controller with SIL2 application
Is there any option/setting needs to be changed from Control builder to make download enable in LEG(Load Evaluate Go) session for AC800 HI Controller for SIL 2 application ?
We are trying to download application (after modification done in engineering environment)form CBM in evaluate enviornment, but it is not allowed to download.
Can anybody help on this?

There is no direct way of enabling this feature, but we need to enable it using system variables and the process will not be documented to prevent unintended consequenses. LEG process in HI controllers is by default blocked in ControlBuilder to prevent overload situations that may lead to a plant shutdown.
LEG is a managed feature that require TSA process so please contact your support care and they will guide you.
