9.13 PROFINET diagnostics9.13.1 OverviewThere are the following possibilities to get diagnostics information from your system:n Diagnostics with the configuration and engineering tooln Diagnostics during runtime in the user program (OB 1, SFB 52)n Diagnostics via OB start informationn Diagnostics via status LEDs9.13.2 Diagnostics with the configuration and engineering toolIf you are connected from your configuration respectively engineering tool via Ethernetwith the PROFINET IO controller, online diagnostics information may be accessed. E.g.with ‘Station è Open online’ you get information about the state of your system. Heremissing respectively faulty components are shown by symbols. In the following figure e.g.there is shown that the configured device 3 is missing and device 4 reports an error.9.13.3 Diagnostics during runtime in the user programWith SFB 52 RDREC (read record) you can access diagnostics data from your user pro-gram e.g. in OB1. The SFB 52 RDREC operates asynchronously, that is, processingcovers multiple SFB calls.More information about the usage of the SFB 52 may be found in theonline help of your programming tool or in the manual "SPEED7 Opera-tion list" from VIPA.VIPA System 300S+Deployment Ethernet communication - PROFINETPROFINET diagnostics > Diagnostics during runtime in the user programHB140 | CPU | 317-4PN23 | en | 18-01146
