#MODBUS MACRO TO SEND FROM MODBUS SERVER 64 BIT#

Public static Int64 ConvertRegistersToLong(int registers, RegisterOrder registerOrder)Ĭonvert four 16 Bit Registers to 64 Bit Integer value – Registers can be swapped Registers: Four Register values received from Modbus Public static Int64 ConvertRegistersToLong(int registers)Ĭonvert four 16 Bit Registers to 64 Bit Integer value Register Order “LowHigh”: Reg0: Low Word….Reg3: High Word, “HighLow”: Reg0: High Word….Reg3: Low Word RegisterOrder: Desired Word Order (Low Register first or High Register first

#MODBUS MACRO TO SEND FROM MODBUS SERVER 32 BIT#

Static Int32 ConvertRegistersToInt(int registers, RegisterOrder registerOrder)Ĭonverts two ModbusRegisters to 32 Bit Integer value – Registers can be swapped Static Int32 ConvertRegistersToInt(int registers)Ĭonverts two ModbusRegisters to 32 Bit Integer value RegisterOrder: Desired Word Order (Low Register first or High Register first) Static float ConvertRegistersToFloat(int registers, RegisterOrder registerOrder)Ĭonverts two ModbusRegisters to Float, Registers can by swapped Registers: Two Register values (int array ) received from Modbus Static float ConvertRegistersToFloat(int registers)Ĭonverts two ModbusRegisters to Float – Example: (modbusClient.ReadHoldingRegisters(19,2)) StartingAddress: First register to be written Write multiple registers to Master device (Function code 16) WriteMultipleRegisters(int startingAddress, int values) StartingAddress : First coil to be written

#MODBUS MACRO TO SEND FROM MODBUS SERVER CODE#

Write multiple coils to Master device (Function code 15)

WriteMultipleCoils(int startingAddress, bool values) Write single Register to Master device (Function code 6) Void WriteSingleRegister(int startingAddress, int value) Write single Coil to Master device (Function code 5) Void WriteSingleCoil(int startingAddress, bool value)

Returns: Int Array which contains the input registers Quantity: Number of input registers to be read StartingAddress : First input register to be read Read Input Registers from Master device (Function code 4) Int ReadInputRegisters(int startingAddress, int quantity) Returns: Int Array which contains the holding registers Quantity: Number of holding registers to be read StartingAddress: First holding register to be read Read Holding Registers from Master device (Function code 3) Int ReadHoldingRegisters(int startingAddress, int quantity) Returns: Boolean Array which contains the coils Read Coils from Master device (Function code 1) Returns: Boolean Array which contains the discrete Inputsīool ReadCoils(int startingAddress, int quantity) Quantity: Numer of discrete Inputs to be read StartingAddress: First discrete input to be read Read Discrete Inputs from Master device (Function code 2) Void Connect (string ipAddress, int port)Ĭonnects to the specified Modbus TCP Serverīool ReadDiscreteInputs(int startingAddress, int quantity) Needed parameters has to be changed using properties.Ĭonnects to the Modbus Server (Modbus Master for RTU) with the previous selected properties.
