OPC/DDE server Frequently Asked Questions
| Question | Upgraded from DS DDE Server to DS Data. Now my client gets error: "Remote data not accessible" and then asks to start DDE. Reference line says "REF" which according to the manual means "DS Data Server is not running." |
| Answer | The reason for this is that DS DDE Server and DS Data have different ServiceNames. DS DDE Server's ServiceName is "DSDDE." DS Data's ServiceName is "DSDATA." Thus there are two solutions to get links working again: · Modify client's reference of the ServiceName from "DSDDE" to "DSDATA". · Edit the ds400.ini file and under the heading "[DSData]" change the "ServiceName=DSDATA" to "ServiceName=DSDDE" If you choose the second option above, then by restarting DS Data you will cause it to now have a ServiceName of "DSDDE" and all the links and tags created for DS DDE Server will now work. |
