Hello, I have a problem connecting WinCC 7.4 to Kepserver OPC. In OPC item manager all groups are browsable and items are available. However, when I open item properties in the field "Item value properties" it says "Invalid Value! (VT_EMPTY)". Although, the current value is displayed. Quality codes for these tags are "0x08 - bad - not connected". On both PCs I use the same account. DCOM settings match the instructions. Attached is the diagnostic capture from Kepserver. What could cause this? Attachment14580272_opcdiag_filtered.txt (79 Downloads) |
