This is the address of the PC with the Remote OPC Server. Use this field if you are using a Remote OPC server. A Remote OPC Server is any OPC Software that is not installed on this SCADA Node.
This address can be a Network Node Name (Microsoft Network Name), a URL or an IP Address. A Remote Server is any PC other than the SCADA node you are configuring.
Unlike other OPC Clients, Web Access can use TCP/IP and IP addresses to access data from a Remote OPC Server. If the Remote OPC Server is not installed on a SCADA Node or Project Node, then the Advantech WebAccess/SCADA OPC Service must be installed on the Remote OPC Server PC for tags to be imported and for real-time data to be exchanged. The Remote OPC Service can be installed from the Advantech WebAccess/SCADA Installation CD-ROM.
This is the Primary TCP Port used by the Remote Advantech WebAccess/SCADA SCADA Node or Remote Advantech WebAccess/SCADA OPC Service. This is determined during installation of the Advantech WebAccess/SCADA software on the Remote Node. (The default, 0 = Port 4592).
If the Remote OPC Server is not installed on a SCADA Node or Project Node, then the Advantech WebAccess/SCADA OPC Service must be installed on the Remote OPC Server PC for tags to be imported and for real-time data to be exchanged. The Remote OPC Service can be installed from the Advantech WebAccess/SCADA Installation CD-ROM.
The OPC Remote Port Time Out is the time (in second) waited before re-sending a communications packet that did not have a reply. Specifies how long the software waits for a response to a data request, specifically, to wait for a reply from one packet.
For OPC Remote Port Timeout, 0 = default = 15 seconds.
If communications to the Server Fails (i.e. exceeds Time Out for a remote OPC Server after three retires), Advantech WebAccess/SCADA will wait the Auto Recover Time before trying to re-establish communications. Advantech WebAccess/SCADA will drop any "open handles" and re-establish new "software links" to the OPC Server. Advantech WebAccess/SCADA will try to restart the OPC Server if the OPC Server is not running.
