v1.6 Patch If you are using v1.6 of the DDE Server and writing data via the DirectNet protocol, you should get this patch.  We have found that once you write to a register location, you will not be able to write to any other location.  For example,  If you are using v1.60 of the DDE server with a 305 PLC, you may experience the following problem:  After writing to R6xx, the server is not able to write to any other location.

To correct this problem, please copy the 'protoccm.dll' file to the BIN subdirectory of where you installed the DDE server, which is usually c:\dirctsft\bin.
