PLC Notifications accessible on OPC UA server

Hi,

I would like to have access to some plc notifications like the internals, warnings, and errors. I know they are accessible with C++. Also, I find your really good RT_Datalogger tutorial.  :) 
My question is if there is some logger or library already finished for picking the notification and exposing them on the OPC UA server on a PLC.
It would be perfect.  o:) 

Thank you
Lukas H.

Hi Lukas,

Thanks for the feedback about the DataLogger tutorial. We are quite proud of that one.

Your idea is an interesting one, and you are not the first to ask for something like this. It would indeed be useful to see a list of notifications from the Notification Logger database on a HMI or SCADA screen.

Unfortunately there is currently no simple mechanism in the PLCnext Runtime to do this. One solution might be for a custom-written PLCnext Runtime component to subscribe to Notifications and then log those notifications as strings in a DataLogger database (rather than a Notification Logger database). As you probably already know, data in DataLogger databases is available as "historical data" through the OPC UA server, so any OPC UA HDA client could read out historical notification messages via OPC UA.

If this is a feature that you would like to see in future versions of the the PLCnext Runtime, then please discuss this with the people in the Phoenix Contact office in your country. They can then raise this requirement through the relevant channels, and hopefully get it on the list of future PLCnext Runtime features. Otherwise, an enterprising developer could develop a component like this and make it available through the PLCnext Store.

Hi Martin,

Thank you for your reply. 
As you say It would be a nice feature but it is not necessary for me at this point. 
DataLogger is a really useful tool and we will use it in projects. 
I will bring up this possibility with Pheonix in the Czech Republic in a future.
