6. Configuring the Gateway
8) Configuring the DeviceNet master PLC outputs: In RsNetWorx, establish a new correspondence between the
data transmitted to the gateway and the PLC outputs, according to the requirements of your application (see
chapter 4.2.7 Configuring Outputs Intended for the Gateway, page 30). The various possibilities offered by
RsNetWorx for establishing a correspondence between the data transmitted to a DeviceNet subscriber and
the PLC outputs will not be covered here. Please see the documentation for this software application to find
out more about this step in setting up a DeviceNet master PLC.
In this guide, we will be using the “AutoMap” command to establish a “raw” correspondence with all of the
data transmitted to the LUFP9 gateway. We then get the correspondence shown below, derived from the one
used with the gateway’s default configuration. The changes in relation to the default configuration are shown
by a greyed-out background, like the “free memory locations”.

9) Transferring the DeviceNet scanner configuration: Following the changes made to the list of DeviceNet
scanner exchanges, it needs to be transferred to the DeviceNet scanner. Please see chapter 4.2.9
