6.5.10 Upgrading with OPC A&E
6.5.10.1 Updating PCS 7 projects with OPC A&E
As of PCS 7 V7.0 SP1, OPC A&E has been expanded to include hierarchical access to the
message system.
You can continue to use the non-hierarchical OPC A&E server.
Updating OPC A&E
If you use OPC A&E with hierarchical access and want to use all functions, an expansion of
the currently used OPC A&E client is necessary.
Starting from the PCS 7version of your project, various scenarios for updating projects with
OPC A&E are described below.
