integración modbus rtu con EASTRON SDM120

[german.cespedes@ecoelec.cl]

hi,

I am new to this forum and I need your help to integrate an EASTRON SDM120 power meter with a spacelink (LSS100200). According to what has been said in the manuals I must create a profile with the data and variables modbus, which is realistic but it does not seem the only thing that needs to be done and that it did not obtain good results. I have read the forum and everything I need to create besides a profile "functions". I will appreciate if I can guide a little to know what I should do more clearly.

register Modbus  https://drive.google.com/a/kuniungen.com...sp=sharing

Then leave the profile you create.

{
"Product_code": "SDM120",
"Fabricante": "Eastron",
"Name": "SDM120",
"Product_range": "PM",
"Descripción": "SDM120 Medidor de energía",
"mapeo": [
{ "name": "Frecuencia", "bus_datatype": "float32", "tipo": "registrar", "dirección": 30000},
{ "name": "Voltaje", "bus_datatype": "float32", "tipo": "registrar", "dirección": 30071}
]
}

Hi,

You can find all information you need to create the profiles in our application note AN027_SL.

See: http://www.schneider-electric.com/en/dow.../AN027_SL/

Key names like Product_code must be in lower case and keys values must be specified in English. Also, register addressing should start from 0: so Voltage address is 0, Frequency address is 70. There's Rtu read test option that you can use to quickly read any register/coil value without having to write a profile. Once you figure out the correct settings you can add them to your profile.
Some more info here: http://openrb.com/docs/modbus.htm

Thanks for the help, you can already perform the complete reading of the meter, even if you have already done card readings of electric generators and other devices.

{"mapping":[
{"bus_datatype":14,"address":0,"type":"inputregister","units":" V","value_multiplier":1,"name":"volts","datatype":"float32"},
{"bus_datatype":14,"address":44,"type":"inputregister","units":" KVARH","value_multiplier":1,"name":"Total Reactive energy","datatype":"float32"}

Hi German, do you solve with SDM120CT?
Which is the right profile code?
I'm trying to use it but is not working for me.
Thanks

Hola,

Si, me fue bien con la lectura, encontré un perfil que cree y lo pongo en adjunto, espero que te sirva.
