Before configuring the Gateway Communication Driver

Please note the following important information before you configure the Gateway Communication Driver:

• Windows Server operating system ICMP(v4) Echo Request may be disabled. You must enable this for an OPC client such as Gateway Communication Driver to connect to the server.

• To determine the status of ICMP (v4) Echo on the server, open a command prompt on the Gateway Communication Driver computer and type:

  ping SERVER_COMPUTER

  where,

  SERVER_COMPUTER: name or IP address of the remote OPC computer.

• If the remote computer does not respond to the ping command, enable ICMP(v4) Request on the remote computer according to the procedure for the Microsoft Windows operating system in use on that computer.

The basic rules for configuring/activating the Gateway Communication Driver are:

• Only one instance of Gateway Communication Driver can run per node without license.

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

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

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

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