Accessing the 800xA OPC Servers
Follow this description when accessing the 800xA OPC Servers remotely from a
third party OPC client.
You need to decide which operations that should be allowed from remote access.
An OPC client accessing an 800xA OPC server remotely will get the same
permissions as the account that the 800xA OPC server is set to run as. The
recommendation is to create a specific Windows user account for OPC access. Then
add this Windows account as an 800xA user and set appropriate permissions.
Configuring DCOM Security for accessing the 800xA OPC AE, DA and HDA
servers is done in the same way. It is only necessary to configure DCOM Security
