Dear Specialists

I'm also using a CP343-1 as profinet controller, with FC11 and FC12, the communications works fine and I'm able exchange data of the inputs/outputs perfectly

But I'm facing a problem, to detec when a profinet station is down. In the past, i use the FB126 to diagnose PN/DP faults, but looking in the diagnostic buffer of the CLP, they not trigger any OB when a profinet station is off line, using a CP343-1 as profinet controller

There is a way  to diagnostic when a profinet station is down, using a CP343-1?

PLC used: 6ES7 317-2AJ10-0AB0 Firmware 2.6.10

CP used: CP 343-1 6GK7 343-1EX30-0XE0 Firmware V3.1.1

Split from Second profinet network with a CPU 319F and CP 343-1.

Thanks towome,

using the FB54 PNIO i was able to diagnose the failures that we want
