Chapter 4. Configuration48 PACSystems* RXi Distributed IO Controller User Manual GFK-2816FMaximum Configuration at Each Update RateUpdate Rate Total Number of Devices per PNC1 82 164 328 6416 – 512 128 (total device limit)If the configuration exceeds the equivalent of eight devices with 1ms update rates, PROFICYMachine Edition will not store the configuration.4.2.2 Basic Configuration StepsThe basic configuration steps for a PROFINET network are:■ Configure the parameters of the PNC.■ Select the PNC and add IO-Devices to its LAN. These IO-Devices can be GE IntelligentPlatforms PNS modules or third-party IO-Devices. PNS modules and third-partyIO-Devices use GSDML files to describe their capabilities. Proficy Machine Editionimports these GSDML files and incorporates the devices into the configuration.Configure the parameters of the IO-Devices.■ Configure the communications properties of the PNC, PNS modules, and third-partyIO-Devices in the Proficy Machine Edition Inspector pane.■ Add modules to the IO-Device remote nodes.■ Configure the parameters of the modules and sub-modules in the remote nodes.■ When the configuration is ready, use the Discovery and Configuration Protocol (DCP)tool in Machine Edition to assign a name to each IO-Device so the PNC can connect tothe devices and deliver their configuration.■ Store the configuration data from the programmer to the RXi Controller.4.2.3 Configuring the Embedded PNCThis section describes one technique to configure the parameters of the RXi embedded PNC.The Proficy Machine Edition InfoViewer describes alternate menus and keyboard operationsthat can be used to perform the same functions.1. In the Project tab of the Navigator, expand the PACSystems RXi Target.2. Click the PROFINET Controller. The PNC parameters are displayed in the ParameterEditor window. Its communications properties appear in the Inspector pane.
