Note that although the Gateway module will have shortcuts to the local computer’s drives (shown as
‘on DALHART’ in the example above), software should not be installed on these drives as they are only
available to the Gateway module when the Remote Desktop Connection is open.
Run the Setup.exe file to start the installation. Follow the on-screen instructions to install the OPC
Server.
Once installed, the OPC Server can be configured using the Remote Desktop Connection facility from
a Windows XP PC. For more details, see the Product Description for the OPC Server (PD 8030).
Using the OPC Server on the Gateway module requires DCOM. For DCOM to function correctly the
OPC Client should be running on a PC that is in the same workgroup as the Gateway Module, and
both the PC and Gateway module are logged in with the same username and password. The users
should also be members of the Administrators group. The Product Description for the OPC Server (PD
8030) describes DCOM configuration.
The OPC server requires a copy of the Trusted TM system application to be available. This does not
require the IEC1131 Toolset to be loaded on the Gateway module. The application folders from the
system toolset must either be copied to the Gateway module, or made available across the Ethernet
network from another computer on the same workgroup. This second method allows a development
station to be used to program the system, with the Gateway module reading the application directly
from the development station. The application folder is specified when adding controllers to the OPC
configuration, as described in PD-T8030.
3.5.2. Operation of the Optional OPC Server
Once configured, the OPC Server will automatically start when the Gateway module is powered up. It
will then start communicating with the Controllers that are configured, and allow OPC clients to connect
to it.
3.5.3. OPC Diagnostics
The T8030 OPC Server can be configured and monitored remotely without a Remote Desktop
Connection, using the OPC Configuration utility. Refer to PD-T8030.
