Remote Communications
If XLReporter is not installed on the same machine as the PCS7, 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 PCS7 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 PCS7, 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 PCS7 is running TCP Port 135 must be opened for remote clients to connect.
