An array of int representing the requested data points data registers on 2 bytes is returned. This address must be in the range of 1 - An array of booleans representing the requested data points is returned. The first parameter of each method is the Modbus address of the queried unit. When the communication is established, the client makes direct calls to the Modbus functions. Serial Line communication uses the CommConnection class Ethernet communication is based on java. When a valid configuration is received, the ModbusProtocolDevice service tries to open the communication port. The ModbusProtocolDevice service also requires a valid Serial Line or Ethernet connection configuration, including the following parameters. actuators.address: The Modbus register address.The ModbusProtocolDevice service needs to receive a valid Modbus configuration including the following parameters.actuators.functionCode:: The Modbus function code.actuators.slaveId: The Modbus device's slave ID.actuators.property: Define data property name.actuators.thingName: Define device name.actuators: Array of Modbus address table for control.Ex: decimal is 2, data is 2635, result is 26.35. cimal?: When data is a numberic, decimal will convert decimal places.sensors.endian?: The payload's endial, little or big or raw, Default is raw.sensors.address: The Modbus register address.sensors.functionCode:: The Modbus function code.sensors.slaveId: The Modbus device's slave ID.sensors.property: Define data property name.sensors.thingName: Define device name.sensors: Array of Modbus address table for read.delay: Set read/write command's delay time.timeout: Set Modbus command's timeout.interval: Set the polling interval, Default is 3000ms.serialPorptions.baudRate: The serial port's baud rate.serialPorptions: The ModbusRTU options.port: e ModbusTCP port, default is 502.path: e ModbusRTU serial port path, ex: /dev/ttyUSB0.type```: dbus client type, support ModbusTCP, ModbusRTU, ModbusRTUBuffered`.For best results you should stick to LTS versions, which are denoted by even major version numbers e.g.
This module has not been tested on every single version of NodeJS.
