Re: Does the IEE allow concurrent CP editing access to multiple users
(i.e. two people able to modify blocks in the same CP at the same time
as long as they are not editing the same block).
Multiple people can work in the same CP. I think the granularity is per
control loop (scheme) rather than per block, but I'm not certain. Guess
I should read the manual. :)
Re: Since the configuration is now stored in a SQL Server database for
the IEE is there transaction and roll back capabilities?
No, it does not. One should consider SQL Server a black-box data
repository. For example, the data stored there cannot be usefully
manipulated through SQL queries.

Does the IEE allow concurrent CP editing access to multiple users
(i.e. two people able to modify blocks in the same CP at the same time
as long as they are not editing the same block).
Since the configuration is now stored in a SQL Server database for the
IEE is there transaction and roll back capabilities?
