'ProWORX 32' and VPN connections

Facts and Changes

'ProWORX 32'....all versions

Causes and Fixes

'ProWORX 32' has never been qualified to work with a VPN but, if the external network components are configured correctly, it will work.

Depending on the security and firewall settings that are configured for the PC, networking hardware and ISP, the customer will be able to establish a connection to the PLC. (e.g., 'ProWORX 32' has been used with the internal 'Schneider Automation' VPN and it works fine. Attempts to use it with the 'Square D' VPN have failed ( Investigation by Schneider Electric's IT group found that login/logout commands that 'ProWORX 32' uses to connect to a PLC were being blocked by a third party ISP). Several other users have reported that the 'ProWORX 32' could only read data from the PLC when using a VPN.) Even if the connection is established, it's security and maintenance cannot be
guaranteed. The connection to the PLC will be at the mercy of the ISP and whatever security settings that are configured on the PC's firewall, anti-spyware or antivirus software and/or network hardware.

Due to the numerous variations of network hardware and configuration settings that can exist, we cannot provide a defined configuration that will be successful with the customer's installed network hardware or software components. Users need to consult with their corporate IT departments and ISP vendor to configure the VPN settings.
