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
