An OPC DA server is identified on a machine by its OPC Server ID. Both the NETx BMS Plattform and the NETx MP Server report as

Typically, an OPC client application provides means for server discovery in the network and/or manual connection configuration.
The NETx Server is able handle multiple OPC client connections at the same time in an independent way. Each connect or disconnect request of an OPC client is logged in the server log.
DCOM configuration
In case of an OPC DA connection through the network, make sure to configure DCOM accordingly.

If both machines are not member of a Windows domain, a common user has to be created on both machines. This user must have exactly the same user name and the same password at both machines. In addition, the user must have administrator rights on both machines.

The DCOM configuration at the NETx Server side consists of three steps:

Configure DCOM settings of NETx Server
Normally, changing the DCOM configuration for a NETx Server is not necessary since the DCOM setting are automatically created during the installation process of the NETx Server. However, if the OPC connection between the OPC client and the NETx Server is not working, it is recommended to verify whether the DCOM settings are correct.
The required DCOM configuration for a NETx Server is identical to the settings of the OPC enum process. To verify them, open the tree “DCOM Config” within the DCOM settings dialogue and locate the entry “NETxBMSCoreServer40” for the NETx Server.
After the correct entry has been found, apply the same configuration steps as described for OPC Enum.
DCOM configuration at the OPC client side
The DCOM configuration the OPC client side is easier than at the NETx Server side, since only the default DCOM settings have to be changed. The required default DCOM settings at the client side are identical to the settings at the NETx Server side. Therefore, open the DCOM configuration dialogue and apply the same settings as described above.
