Hello
We install PCO on many workstation in our plant ,most are WinCC , one is Hollysys MACSV , most of PCO work fine with WinCC, but we found PCO could not get Tag Data from WinCC on 2 of WinCC workstations ,error message is "Tag not found " , we double check the tag name and be sure the name is correct ,and when we try to browse the tag using Alias of PCO , PCo will return a message box with "the browse request returned with error" ,we could not browse any tag/group in alias configuration .
if we use other OPC Client (http://downloadnew.org/company/s-chepurin/) , everything works fine ,we could add a Tag and get the correct value , that 's really confusing , is any config for PCO or WinCC for our scenario? and we also found same problem in MACSV DCS workstation , so we thought that maybe something with PCO self.
any comments is appreciated .
version PCO : 2.1.6 MII 12.2 , WinCC 6.1 with SQL Server on XP SP2
