The WAGO BootP server allowsany IP address to be easily assigned for the WAGO (programmable) fieldbuscoupler or controller. You can download a free copy of the WAGO BootPserver over the Internet at: http://www.wago.com.More informationThe procedure for address allocation with the WAGO BootP Server isdescribed in detail in the Chapter “Starting up a Fieldbus Node”.The BOOTP Client allows for dynamic configuring of the networkparameters:Parameter MeaningIP address of the client Network address of the (programmable) fieldbuscoupler or controllerIP address of the router If communication is to take place outside of the localnetwork, the IP address of the routers (gateway) isindicated in this parameter.Subnet mask The Subnet mask makes the (programmable) fieldbuscoupler or controller able to differentiate, which parts of
