Yes, the IEE allows for multiple users to use this configuration tool to configure into a single CP. You are right in assuming that each independent user can not edit the same block. Each set of blocks are in a strategy, which only has access one user at a time in edit mode. The I/A configuration uses the SQL Server database for house keeping, but does not use this database to store the actual configured objects. Once the object has been saved and checked in this becomes a new object. The entire Galaxy Repository (GR) can be saved with built in tools. This GR can be restored at any time overwriting any changes in your Configurator. This is only making changing an off-line Configurator, not making any changes to the I/A control running in a CP. This is different from ICC which is more of a runtime configuration tool. When the changes are made, the changes are were sent directly into the CP and the workfile.

Since the configuration is now stored in a SQL Server database for the IEE is there transaction and roll back capabilities? =20 =20 _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
