I think you need an OPC server into the SCADA that must exist in the PC directly connected to the S7-400, then using VPN , install an OPC client into the remote PC..It should works What kind of SCADA do you use? Wincc have it Alternatively use Teleservice http://www.automation.siemens.com/mcms/simatic-controller-software/en/diagnostics-options/simatic-teleservice/pages/default.aspx Edited 16 Dec 2013 by fleaplc

We don't really know what the 'other pc' does. If it does trend or logging,you'll need what fleaplc says. However if you just need to receive that data you may consider email function, is cheaper than buy an opc or scada licence.
