Hello,

 in forum there´s often the question, how to read out port or mrp status via program.

Now, there is a new entry in Siemens Online Support.

With the "LPNDR" block library, you receive function blocks with which you can read various device and status information from a PROFINET device and describe parameters.
You can use the library blocks to perform the following functions:

• Reading the device information:

  • Information via 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 in MRP, e.g. client, manager

  • Port statistics information, e.g. number of received bytes

• Readout of the MRP status

• Modification of the parameters of an analog input module of the ET 200SP at runtime, e.g. to enable and disable channel diagnostics.

Hello,

That is a good function.

Is there any similar blocks for classic step 7 also?

Kbv.

no Sorry,

only for TIA and S7-1200/1500.

You can find an example on reading the IP Address out in this Example

In STEP 7 V5.5, how do you read out the IP address of the S7-300 CPU in the user program?

It's based on reading System Satus Lis (SSL). You can find a list of SSL_ID's in this manual from page 669
