    Seneca for further information. The StratON PLC provides a “Redundancy” functionality: when this feature is enabled, two CPUs (Z-TWS4 or Z-PASS2-S or S6001-RTU) run the same StratON application; the two CPUs connect each other via the Ethernet, in order to keep variables, state-machines etc.

A detailed description of Z-TWS4/Z-PASS2-S/S6001-RTU VPN configuration parameters is given in 18.1.4 paragraph. The following two sub-paragraphs give some more info about the two kinds of VPN.

  • Page 51: Point-To-Point" Vpn

    In this scenario a PC (acting as a VPN Client) can connect, on demand, to only one Device and its subnet, using local IP addresses. Since the client “sees” just one Z-TWS4/Z-PASS2-S/S6001-RTU (and attached devices) at time, the same subnet configuration can be assigned to different sites, without creating conflicts.
