Hi experts

I have a machine where several profinet modules are used, 
S7-1214 (Firmware V4.2) CPU
TP1200 comfort panel
One FESTO Stepper motor controller (CMMT-ST-...-MP)
One FESTO CPX module (Terminal valves with Inputs)

I want to use the "System Diagnostics View" to display infrmations, such as 
1) if a device is reachable (Maybe the fuse protecting the device's power supply is burnt / The PROFINET Cable is non functional ...)
2) if network problems occurs (bad node adresses)
3) If one of the CPX modules is unplugged, at what rank ? ...

The goal is the help the maintenance staff figure out the problems in the machine quickly, without opening the electrical panel)

What should I do step by step in both HMI and PLC (or other devices if necessary) to get things done.
I think the runtime settings in the HMI are already done, see attachement

I already consulted some examples in the net
"How to obtain diagnostics of a CPX-AP-I-PN-M12 (Profinet) using the RALRM instruction"
https://www.youtube.com/watch?v=22AMdhe0MTM

and one other SIEMENS project example (ID 109480387)
https://support.industry.siemens.com/cs/ww/en/view/109480387 

but it only write the infos to DB to be used later in the PLC program, not in the "System Diagnostics View"

With the below settings, i only get the diagnostics view with 4 grayed buttons on the bottom 

What did I miss out ?

Thank you for your help.

Hi again everyone,

I contacted FESTO support regarding this topic, and they confirmed that it’s possible to collect diagnostic information using the RALARM instruction and store it in a PLC data block, then display those values on the HMI using tags. They also mentioned the D_ACT_DP instruction to identify the slot/rank in case of CPX-AP network issues.

However, my original question is more about the Siemens "System Diagnostics View" feature:

Is it possible to make the System Diagnostics View on the TP1200 Comfort panel show the diagnostic data (unreachable devices, PROFINET faults, missing modules, etc.) for non-Siemens PROFINET devices such as Festo CMMT-ST and CPX modules?

Or is this feature limited to Siemens devices only, meaning that for third-party devices I need to use the RALARM + DB + HMI tags method instead?

Any clarification/confirmations or examples on how to make the System Diagnostics View fully functional with mixed PROFINET networks would be very helpful.

Thanks again for your time!

For anyone interested

Due to the relationship of this diagnostic view with the hardware, it was necessary to compile both the hardware and software in the PLC and HMI before downloading the software to both equipments, in order to view the messages in the diagnostic view.

No it is working fine.
