Measurement of energy stops when the voltage is less than 180 volts (the failure or interruption of the voltage), the threshold is set in one of the Modbus-registers of the meter. | Measurement of energy stops when the voltage is less than 180 volts (the failure or interruption of the voltage), the threshold is set in one of the Modbus-registers of the meter. | ||

At the physical level, the module is connected via RS-485 interface. Modbus RTU Protocol is used to control the meter. In Wirenboard Devices, Modbus data is transmitted over RS-485 communication lines. See the [[Протокол Modbus/en|Modbus Protocol]] page for details. Modbus-the address of the counter is set at the factory and marked on the label. The address can be changed programmatically. Details refer to the [[#Управление по Modbus| Modbus control]]. | |||
