The way in which the user interface of the SFC250 can be accessed with an Internet-
compatible device differs according to the technical solution selected.
If the access point in the cellular network and the fixed IP address is made available by
a specialised service provider, the IP / URL for accessing the device must also be
retrieved from that provider. Often, the access occurs over the service provider’s
password-protected portal containing corresponding direct links.
With the VPN solution, it must first be ensured that the device used can create a secure
VPN connection to the supply module. This requirement is met if the end device is a part
of the network connected with the VPN gateway (e.g. workstation PC in the company
network) or the device itself has been logged on as a client to the VPN server. To call up
the user interface, only the IP address assigned to the supply module then needs to be
entered in the address line of the browser.
