This is how to use SecurityBridge

SecurityBridge can be connected upstream of the base unit of PNOZmulti or the PLC controller PSSuniversal PLC. It acts as a VPN server, over which a virtual private network (VPN) can be established to one or more client PCs (configuration PC). The connection between PC and device is thus protected. Only suitably authorised users can make changes to a project’s configuration. This prevents unauthorised access to the secured network. The result is that the data transfer between the client PC and SecurityBridge is protected against tapping and manipulation.

The SecurityBridge also controls the process data traffic, and it monitors the integrity of the safety system. Changes in the check sum indicate that there are changes in the projects of PNOZmulti and PSS 4000.
