Previously, when using WinCC V7.5, I could connect normally to the OPC Server software (MX OPC and Kepware Server). But since updating to WinCC v8, I can't connect anymore, in the Tag Management it shows connection status Unknown (with the question mark on OPC name). I have enabled OPC DA Server Process when starting WinCC Runtime and fully configured DCOM. Anyone have solution for this problem? Thank you Attachment Error opc.PNG (290 Downloads)
