AC500 OPC server problem.
Hi im having problems configuring AC500 OPC server V3, for use with digivis 500 in windows 7 64bits. (Everything works fine in win XP).
When i install the OPC server V3 and try to connect i get the following error:
COM/OPC Error 0x80004005 on cocreateinstance(), (screenshot attached)
I cant connect with Matrikon or any other clients and the OPC Tunnel is not working.
Default DCOM settings were changed between Win XP and Win 7 in an attempt by microsoft to increase security. ( But instead it just broke stuff like this ) Check your DCOM settings ...
DComConfig->Component Serives -> Computers -> My Computer, Right Click
->Properties-> Com Security
Access Permissions -> Edit Limits -> Add "Everyone" Local & Remote Access
Launch and Activate Permissions -> Edit Limits -> Add "Everyone" Local & Remote Access
For AC500 OPC server V3.5.2 everything will get registered by itself in windows 7 64 bit pc and check where ".ini" file got saved,it should be C:\ProgramData\CoDeSysOPC\
If not registered please follow the screen shot for OPC server registration.
then restart the pc and make DCOM setting as per the documents available in following location C:\Program Files (x86)\3S CODESYS\CODESYS OPC Server 3\CoDeSys_OPC_Server_V3_User_Guide.pdf and refer page no:36
If above info not solved your issues please provide which Control builder plus you are using? and version of codesys opc server?
