8.13 PROFINET diagnostics
8.13.1
Overview
There are the following possibilities to get diagnostics information
from your system:
n Diagnostics with the configuration and engineering tool
n Diagnostics during runtime in the user program (OB 1, SFB 52)
n Diagnostics via OB start information
n Diagnostics via status LEDs
8.13.2 Diagnostics with the configuration and engineering tool
If you are connected from your configuration respectively engineering
tool via Ethernet with 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. Here missing respec-
tively 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.
8.13.3 Diagnostics during runtime in the user program
With SFB 52 RDREC (read record) you can access diagnostics data
from your user program e.g. in OB1. The SFB 52 RDREC operates
asynchronously, that is, processing covers multiple SFB calls.
More information about the usage of the SFB 52 may be
found in the online help of your programming tool or in the
manual "SPEED7 Operation list" from VIPA.
