9.13 PROFINET diagnostics
9.13.1
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
9.13.2
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 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 program
With 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, 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 Opera-
tion list" from VIPA.
