Compatibility rules for CCT and field controller revisions - Metasys - LIT-12011832 - General System Information - Metasys System - 12.0

All revision-to-revision upgrade combinations for equipment controller/CCT applications are tested in the Product Development Test Labs.

Starting at CCT Release 10.1, CCT is used to configure, simulate, and commission equipment controllers on an N2 Bus. With CCT 10.1 or greater, you can open and commission an application created with an earlier revision of CCT.

Equipment controllers running different firmware revisions can be mixed and matched on any Engine with MS/TP Integration. This means that Release 5.3 based equipment controllers can be added to a Release 4.0 NxE's MS/TP Integration. The only risk is that some enumerations that were created in the 5.1 .caf may not display properly in the engineering view for the equipment controller.

The CCT upgrade process works between major and minor revision levels (for example, CCT Release 10.0 to 10.1). CCT applications created during Alpha and Beta site releases (for example, 3.0.22 to 3.0.25) do not automatically upgrade.

The .caf files created by CCT are independent of the version of SQL Server (for example, a .caf file created on a customer's machine running SQL Express) can be opened on a Branch laptop using Microsoft SQL Server Data Engine (MSDE).
