GOOD MORNING ALL,
I AM USING ATR144-ABC-T COMMUNICATING VIA RS485 WITH A HMI.

IN MY APPLICATION (FOR HEATING PURPOSE)
THERE IS NEEDED TO MODIFY THE ACTUAL TEMPERATURE (FOR E.G IF TEMP ACTUAL IS 25°C, I WANT TO SHOW IT AS 30°C BY MODIFYING PARAMETER IN MENU). THIS WORKS FINE VIA KEYPAD.

BUT I WANT TO MODIFY THIS OFFSET VALUE VIA MODBUS.
AFTER THORIUGHLY CHECKING LIST OF MODBUS REGISTERS, I FOUND THAT IT WAS NOT LISTED THERE.

HENCE I AM REQUESTING IF ANY ONE HAS ANY IDEA HOW TO ACCOMPLISH THE TASK ?

THANKS IN ADVANCE

******** ITALIAN ********
BUONGIORNO A TUTTI,
STO USANDO ATR144-ABC-T COMUNICANDO TRAMITE RS485 CON UN HMI.

NELLA MIA APPLICAZIONE (PER SCOPO DI RISCALDAMENTO)
È NECESSARIO MODIFICARE LA TEMPERATURA EFFETTIVA (PER ESEMPIO SE LA TEMPERATURA EFFETTIVA È 25 ° C, VOGLIO MOSTRARLA A 30 ° C MODIFICANDO IL PARAMETRO NEL MENU). FUNZIONA BENE TRAMITE TASTIERA.

MA VOGLIO MODIFICARE QUESTO VALORE DI OFFSET TRAMITE MODBUS.
DOPO AVER CONTROLLATO ACCURATAMENTE L'ELENCO DEI REGISTRI MODBUS, HO TROVATO CHE NON ERA ELENCATO QUI.

QUINDI STO CHIEDENDO SE QUALCUNO HA QUALCHE IDEA SU COME ESEGUIRE IL COMPITO?

GRAZIE IN ANTICIPO

Good morning,
all parameters are available from the 2000 register onwards. For example, if you want to change parameter number 8 [o.CA.1] (Offset calibration) you must change register number 2008. Same procedure for all parameters.

Best Regards.
