PCO Error - failed due to Unexpected error of the communication

Hi All,

We are using OPC S7 200 PC Access which is installed in Windows XP system and PCo 2.3 is also installed in same system. We have configured the OPC as source in PCo and destination is MII 14.0. We also created notification Agent and Subscribe Item browse the tags from OPC. Query Port (9000) is also configured in PCo.

Now we are able to connect PCo with MII through PCoConnector. In MII workbench we have used PCo Query with Tag Store Query Mode to write tag value from MII. Currently we are testing with one tag only. We selected the tag (SControl1) and added in list and put some dummy value (1). When we are executing, getting an error like “failed due to Unexpected error of the communication..” We set the PCo in Verbose mode and captured the log. Could you please provide any suggestion.
