Clock Event Hardware and Software type not working

[gopikaops]

Hi Team I am trying to get Hardware and Software type event data. This is my DRF request - B:VIMIN@E,10,S,0 and B:VIMIN@E,10,H,0

I am referring the DRF - https://www-bd.fnal.gov/controls/public/drf2/#event

The Clock event uses signals provided by the global timing system.

clock-evt         = "E," evt-number [ "," type [ "," delay ] ]

evt-number        = hex-number                             ; evt-number < 216

type              = "H"                                    ; hardware 
                  | "S"                                    ; software
                  | "E"                                    ; either one (default)

delay             = time-freq                              ; default is 0

This is the error I am getting -

Here is my code - https://github.com/fermi-ad/gmps-ml/blob/main/collection_gmps_ml_project_parameters.py Additionally, I am able to get all the data with default type : B:VIMIN@E,10,E,0

When you get a response, it can be data ItemData or a status ItemStatus. The status is an error that communicates why you didn't get data. These stack traces tell you that you didn't account for ItemStatus coming back because the ItemStatus class doesn't have a data attribute; only ItemData has a data attribute.

If you're using an .is_reading check or .is_reading_for like below, the else condition will be an ItemStatus. You can print that status to get more information.

        # Process incoming data
        async for evt_res in dpm:
            if evt_res.is_reading_for(0):
                # This 0 argument matches the tag in `add_entry`
                if evt_res.is_reading_for(0):
                    print(evt_res)
                else:
                    # This is responses to tags that aren't 0
                    pass
            else:
                # This is likely a status response
                pass
                # You could print the status
                #print(f'Status: {evt_res}')

You are getting an error because what you are requesting doesn't exist. Here are the two event configurations I found for B:VIMIN. e,14,e,0 and e,10,e,0 So, when you request

B:VIMIN@E,10,S,0 and B:VIMIN@E,10,H,0

The logger can't find a match to your request. It's probably returning a "node not found" error, which tells you that no configuration matches your request.

If you want data with these configurations, you must create entries in D43 for them.

Let me know if I missed the mark on this. Let's figure out what you need!
