hello ,
how to check if the profinet connection is stable or not and display it in the scada screen?

for example there is a profinet cable from scalance to VFD and if the connection is lost or there is a breakage in the profinet cable, how do i fetch the data that this particular profinet cable port has issue and i need to display it in the scada screen?

im using tia portal v20 professional wincc RT professional.

I think the LPNDR library will help. It can read the status of Profinet port, and you just need to add some commands.

what should be given at the execute?? 
im not able to get the output . i have created an event in PLCsimulation (plug and pull ).
.It shows there is no error even though there is an error which i have triggered through event in PLCSIM.

plz check the image attached
