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 WebAccess 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 WebAccess Installation CD-ROM.
This is the Primary TCP Port used by the Remote WebAccess SCADA Node or Remote WebAccess OPC Service. This is determined during installation of the WebAccess 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 WebAccess 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 WebAccess 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) WebAccess will wait the Auto Recover Time before trying to re-establish communications. WebAccess will drop any "open handles" and re-establish new "software links" to the OPC Server. WebAccess will try to restart the OPC Server if the OPC Server is not running
This is the Remote Access Code established during installation of the WebAccess software (SCADA Node, Project Node or OPC Service) on the OPC Server computer. The access code you enter here must match the Remote Access Code established during installation on the OPC Server. This prevents unauthorized users from accessing the OPC Server data using the WebAccess OPC Service.
