Summary:
Why is the PROTDIR.DBF file now in the project directory as well as the \CITECT\BIN directory? If I add a protocol to the PROTDIR.DBF in the \CITECT\BIN directory do I need to add it to the PROTDIR.DBF in the project directory? 

Solution:
In version 5.10 and later the PROTDIR.DBF file is now included into your project and compiled. This file is used at runtime by the CTAPI and the OPC server to dynamically block tags in the same way as the I/O Server. If you have added a protocol to the PROTDIR.DBF in the \CITECT\BIN directory and not to you project, then the CTAPI and the OPC server will not be able to block data requests for that protocol. The CTAPI and OPC server will still be able to read and write data, however you will not get full performance.

If you add a protocol to the PROTDIR.DBF in the \CITECT\BIN directory you should then copy that PROTDIR.DBF TO THE \CITECT\USER\INCLUDE directory. This file is an exact copy of this file. The PROTDIR.DBF files in your project directory can remain empty as all the information is contained in the include project.
