About the Gateway Communication Driver

The Gateway Communication Driver acts as a communications protocol converter. It can be used to link clients and data sources that communicate using different protocols.

This user assistance publication covers only the information you need to configure and run the Gateway Communication Driver component. The documentation that accompanies the related components provide details on their operation.

You can troubleshoot problems with Gateway Communication Driver using the Log Viewer, a snap-in to the Operations Control Management Console (OCMC). See the Log Viewer help file to find information on:

• Viewing error messages.

• Determining which messages are shown.

• Bookmarking error messages.

You may also be able to troubleshoot problems using your client application, such as the InTouch HMI software. The client application can use system device items to determine the status of nodes and the values of some parameters.

The basic rules for Gateway Communication Driver include:

• One instance of Gateway Communication Driver can run per node.

• The Gateway can be activated and deactivated using the OI Server Manager snap-in.

• The Gateway can be activated as a COM Server (OPC Server) using standard COM activation mechanisms.

• The Gateway can be run only out-of-proc within OPC clients.

• The Gateway can communicate only with ArchestrA data source components delivered with Application Server v2.0 and later. Earlier versions of Application Server are not supported.
