The C++ Interface supports the use of the C++ object oriented programming language on top of the RTAP/Plus platform. The C++ Interface substantially reduces the amount of program code required for applications, thereby decreasing the cost of custom applications.

Libraries are available for both C++ and C++ using exception handling. The following RTAP objects are supplied:

* general RTAP object
* database object (with database event handling and plotting)
* scan system object
* alarm system object
* data historian object
* time keeper object
