Remote Communication
If XLReporter is not installed on the same machine as DeltaV Advanced Continuous Historian, the workstation must also have the OPC core components installed. To determine if the core components are installed verify the following file exists:
C:\Windows\SysWow64\OPCEnum.exe (64-bit OS)
C:\Windows\system32\OPCEnum.exe (32-bit OS)
If the components are not installed, then they are provided in the XLReporter installation folder under _repairtools\OPC. Alternatively, these can be downloaded from www.opcfoundation.org.
Server Settings
To connect to DeltaV Advanced Continuous Historian remotely both the machine where the server is running and the machine where the client is running must have matching Windows user accounts and the client must be logged in with a matching account.
In addition, on the machine with the DeltaV Advanced Continuous Historian, certain DCOM settings must be enabled. For details on what DCOM settings to enable, see OPC and DCOM: 5 Things You Need to Know.
Windows Firewall
If the Windows Firewall is enabled on the machine where DeltaV Advanced Continuous Historian is running TCP Port 135 must be opened for remote clients to connect.
