¿"Canales registros"?

[danielcuellarp]

Hello, does anyone know if this Circutor meter "Record Channels" configuration is implemented in the library and/or to which ASDU does it belong?

You must use the extended protocol ASDU 162 (Instant values request) and the data you need by code/name and the returned ASDU parsed an stored in the related object:

# 163 response
INSTANT_VALUES_OBJECTS = {
    192: {
        'name': 'totalizadores',
        'object': 'TotalizadoresInstantaneos'
    },
    193: {
        'name': 'potencias',
        'object': 'PotenciaInstantanea'
    },
    194: {
        'name': 'I_V',
        'object': 'IVInstantaneos'
    }
}

There's an AppLayer function to make the request as seen in the example below:

        #### INSTANT_VALUES_OBJECTS name or code (Extended)
        logging.info("LEER VALORES INSTANTANEOS {}")
        instant_objects = ['totalizadores', 'potencias', 'I_V']
        logging.info("Get instant values")
        resp = app_layer.ext_read_instant_values(objects=instant_objects)
        print(resp.content)

A complet example is shown in https://github.com/gisce/iec870ree/blob/master/examples/ip_cliente.py

Hello, the request that you mention brings me the information of "instantaneous values" correctly, but what I need is the one of "record channels"

We haven't found the ASDU neither REE neither IEC documentation that we have available. If anyone knows the ASDU and its structure, we can implement it.
