Trying to configure a profile to store register values

Thanks for your response.

What is not clear to me yet is the following.

I need to do two things:
- Write register value
To set the register value, do I do it by setting a Capture Object on the ProfileGenericObject?
Using the addCaptureObject method?
- Set capture period to a meter for the register value to be written
Setting the capture method is clear I think and I believe I have set it the correct way with the code above?

To save this, I need to use the Capture method, right?
I used the capture method in the last step (# save) but it seems not to have done the work.
As attribute I gave pg.client, but possibly I didn't do this the correct way?

"The capture method will generate a message that asks meter to save current values for the buffer."
Is this a physical message that needs to be accepted?

I have a Mac so I sadly dont seem to be able to run GXDLMSDirector.

Thanks again for your initial response

Thank you for your response,

I am aware that I can't write the register value - I was not very clear in my previous post.
What I meant is the following; that I want to write the Register object value in the buffer of a ProfileGeneric object.

I found a windows and played around with GXDLMSDirector.

I created a profile generic object (configurable) with Logical Name: 0.0.99.1.0.255
I added two Capture Objects: Clock (0.0.1.0.0.255) and an Extended Register (0.1.24.2.1.255).
I specified the Period: 900
And clicked on 'Capture'
It gave me a message: "action accomplished'.

It seems to have worked, so now I know it is possible, thanks!

However, the actions I took through the gxdlmsdirector follow the same logic as I tried to implement in the code I showed before.

Now I understand how to create / initialize a ProfileGeneric object, and how to set a CapturePeriod.
What I don't understand is how do add a Capture Object correctly to this Profile Generic object.

I did the following, Is this the way to do it?

#Add Capture Object
pg.addCaptureObject('0.1.24.2.1.255', 2, 0) #(pg is a Profile Generic Object initialized at the start)

After adding the Capture Object, I want to capture the values of this object.
I tried to capture these values with the Capture function through:

pg.capture(gp.client)
It requires a 'Client' parameter (as see in the docs). But I am not certain that this is the way to access the client correctly.

Other than that, I need to make sure that the newly set capture objects are saved to the meter, not only saving the values of the capture objects on the moment of the capture.
I understand there is a 'write' operation involved here, however I can't seem to find out how to do it
I tried to implement it this way:

# Write capture objects
gp.reader.write(pg.captureObjects, 3)
gp.reader.write(pg.capturePeriod, 4)

________________________________________________________________________________________

My full code is this:
# Connect with meter (Authentication: LOW)
gp = reader.connect(row)

# Create ProfileGeneric object (=configurable profile)
pg = GXDLMSProfileGeneric(ln = '0.0.99.1.0.255')

# Set capture Period (900) = 15min
pg.capturePeriod = 900

# Add capture object (values of register '0.1.24.2.1.255' should be captured every 15 mins)
pg.addCaptureObject('0.1.24.2.1.255',2, 0)

# Capture method saves the new params
# pg.capture(gp.client)

# Write capture objects to meter
gp.reader.write(pg.captureObjects, 3)
gp.reader.write(pg.capturePeriod, 4)

Kind regards,

Dear Mikko,

Thanks again for the response.

Sadly, writing to the meter doesn't seem to work.

Following code:
# Write capture objects to meter
gp.reader.write(pg.captureObjects, 3)

Gives following error:
AttributeError("'list' object has no attribute 'getValue'",)

Apparently it seeks for a 'getValue' attribute but I cannot seem to be successful in passing the correct parameter.

When printing out following pg.captureObjects; I get:
[('0.1.24.2.1.255', <gurux_dlms.objects....128091cf8>)]

A list of tuples with first tuple the logical name of the register, and second tuple the Capture Objects.

When passing only the Capture objects; eg: pg.captureObjects[0][1] to the write function, I get following code and error:

code:
gp.reader.write(pg.captureObjects[0][1], 3)

error:
AttributeError("'CaptureObjects' object has no attribute 'getValue'",)

Any idea on what I could be missing? I feel like this is just the last step in a correct implementation

Kind regards,

Jean-Baptiste

Dear Mikko,

Thanks! I got it to work.
Full code that works:

pg = GXDLMSProfileGeneric(ln = '0.0.99.1.1.255')

extended_register = GXDLMSExtendedRegister(ln = '0.1.24.2.1.255')
clock = GXDLMSClock()
pg.capturePeriod = 900

pg.addCaptureObject(clock, 2, 0)
pg.addCaptureObject(extended_register,2, 0)

gp.reader.write(pg, 4)
gp.reader.write(pg, 3)

Thanks again.

Kind regards
