Hey folks! I spent a week trying to figure the problem out but no luck.
Please, give any advices, guys.
I have:
1) Old ABB Advant AF100 OPC server that is connected to the field and obtains data from devices. OPC is installed on old Windows NT and uses to drive local SCADA on the same machine. Localy it works ok.
2) Kepware Kepserver EX V4 on Windows Server 2008 which obtains data from many devices\OPCs to drive main SCADA (server 4). It also obtains data from server №1 using OPC DA driver. It was configured many years ago and it works ok on SCADA.
3) Kepware Kepserver EX V5 on Windows Server 2012 which is a copy of server №2 in scope of OPC configuration (same devices, but different versions of Kepserver).
4)FactoryTalk SCADA on remote server.
The purpose is to migrate all devices and chanels from old OPC server 2 to new server 3.
I migrated 99% of that stuff from old OPC server to a new one and it works ok, except ABB Advant AF100 OPC.
I can not figure the problem out. It simply can not connect to server 1.
I have the same user on all machines, the same DCOM configuration on server 2 and server 3. I have no problem with network connection between all of them.
When I tried to use OPC Quick Client on server 2 to connect to server 1 I got error message (Wrong CLSID). Nevertheless it works OK on SCADA. I see the data, but sometimes i need to wait up to 5 minutes.
I tried to use OPC Expert from server 2 and 3 to define the problem but it says I do not have permissons to connect.
I can not even browse OPC instances installed on server 1.
I also have checked there is no Opcenum on server 1. May this cause the problem?
Where I need to dig, guys? I am run out of ideas. Thank you in advance.
