Security RouterActive componentsVirtual Mapping with Weidmüller’s RouterBVirtual mapping—or, NAT—enables you to operate simultaneouslyseveral identically configured networks behind routers equippedwith NAT capabilities. The system engineer can hide the systembehind the router and needs not adjust its IP configuration. Thisallows using the system with the same configuration over andover again. NAT is required as an alternative to port suffixesThe advantage of virtual mapping:Two or more machine networks with the same configurationcan be connected to a superordinated network without anychanges.Production System 1Production System 2OfficeAdditional Features for Convenient Data CommunicationsModemWeidmüller Routers support modem connections for dial upconnections to the router. This feature is extremely valuablefor remote maintenance in situations where a direct connectionof the network to the internet is undesired. Different typeswith built-in Analog-, ISDN- or GSM-modem are available,alternatively an external modem can be connected.Highspeed RoutingBased on his high performance architecture the Router is ableto forward data with nearly wire speed (100 Mbit/s). This is animportant feature for high speed applications and applicationswith large data volumes.Integrated ServersThe router provides additional network functionalities thatnormally require a separate computer, for example automaticaddressing and automatic time serving and synchronization.Dial on Demand and CallbackWhen a router is used to connect a network to the internet overa modem, Dial on Demand comes in handy to cut costs. In thisconfiguration the router establishes a connection only when adevice in the network wants to download data from the internet.When it is done, the router disconnects automatically.Callback is often used for remote maintenance purposes. Therouter dials a preset phone number, e.g., that of the systemmanufacturer‘s service center. This means that the dial-up costsare borne by the customer.B.50
