IndexGFK-2839B PAC8000* IO PROFINET Scanner User’s Manual–September 2017 7Chapter 1. IntroductionThis chapter provides an overview of the PAC8000 PROFINET Scanner (PNS) module andits operation. This chapter also includes a list of the PAC8000 IO modules that can beincluded in the PAC8000 PROFINET Scanner IO-Device.Chapter 2, Installation, gives instructions for PNS installation, panel-mounting, grounding,installing power supplies, and updating firmware. It also describes powerup and restart, andLED operation.Chapter 3, Configuration, describes how to configure the PNS and its IO modules.Chapter 4, Diagnostics, describes the input and output data that can be used to monitor andcontrol the PNS. This chapter also explains how the PNS reports errors to the control system.Chapter 5, PROFINET Specifications, summarizes the features specified for PROFINETv2.3 Class A IO-Devices that are supported by the PAC8000 PROFINET Scanner module.1.1 PAC8000 PROFINET Scanner OverviewThe PAC8000 PROFINET Scanner (PNS) module interfaces PAC8000 IO modules to aPROFINET IO network. The PNS scans the input modules in the node (retrieving input dataand providing output data), publishes input data on the PROFINET network at the configuredupdate rate, and receives data for output module outputs.The PNS manages PROFINET communication and IO module configuration between an IO-Controller and IO modules of PNS. If network communications are lost, the PNS manages I/Ostates according to the individual module configurations.Input and Output data are coherent over a full scan of the IO modules. All input data readfrom one scan of the IO modules is kept together and then sent over the PROFINET network.Similarly, outputs delivered on the network are sent to the IO modules as a unit. If newoutputs arrive during the writing of data to the output modules, the PNS continues to write tothe outputs using the previous data until all IO modules have been updated before switchingto the newly delivered data.
