Per “OPC Common Definitions and Interfaces Version 1.1” (9.5) The OPC Component categories for the various OPC Server types are defined in opc_cats.c. However, there is no opc_cats.c file in c: \ Program Files (x86) \ Common Files \ OPC Foundation \ Include \ installed by OPC Classic Core Components 108. Which package does the opc_cats.c file install and where?

The constants referred to by the specification are published in the *_i.c files (look for the CATID_ prefix).
