Evaluate Diagnostics In The User Program - Siemens SIMATIC ET 200AL System Manual

Library for PROFINET data records
The "LPNDR" block library contains various function blocks. You can use these blocks to read
out various device and status information from a PROFINET device and write parameters.
You can execute the following functions using the library blocks:
• Read device information:
– Information about the interface, e.g. IP and MAC address
– Information about the device interface, e.g. status, medium, name
– Information about the link status of the interfaces, e.g. link down, link up
– Information about the role of the device for MRP, e.g. client, manager
– Information about the port statistics, e.g. number of received bytes
• Read the MRP status
• Modification of the parameters of analog input module of the ET 200SP in runtime, e.g. in
order to disable/enable the channel diagnostics.
The finished functions are freely adaptable and can therefore be used universally.
The "LPNDR" block library with an example project can be found on the Internet

Diagnostics in the user program
For PROFINET IO, a cross-vendor structure of data records with diagnostics information
applies. Diagnostics information is created only for channels on which a fault has occurred.
With PROFINET, there are two basic ways to obtain diagnostics information.
