ModbusClient_TCP

ModbusClient_RTU

SimpleReadValue

Short description

Used to read a Modbus value of various function codes as well as various data types up to 64-bit values. Addresses to be read are automatically expanded to up to 4 registers for values larger than 16 bits. The raw values can always be processed directly via an array. As a parameter, there is the option to scale values directly.

Special feature: Evaluation of actual values for function codes 01 ( Read Coils ) and 02 ( Read Discrete Inputs )

When evaluating the actual values, only the output ‘arwRawValue’ must be considered. This is an array consisting of four variables ‘arwRawValue[0]’ - ‘arwRawValue[3]’ of type WORD ( = 16 bit ). The determination of the bits to be transmitted is primarily determined by the choice of the function code ( eFunctionCode ) and the start address ( wRegisterAddr ). The number of bits to be transmitted is determined by the choice of the expected data type ( eExpectedType ). Therefore, depending on the data type, 16, 32 or 64 consecutive bits are transmitted. At least 16 consecutive bits are always transmitted. The actual values are available as follows: 16 transmitted bits: actual values in ‘arwRawValue[0]’ 32 transmitted bits: actual values in ‘arwRawValue[0]’ and ‘arwRawValue[1]’ 64 transmitted bits: actual values in ‘arwRawValue[0]’, ‘arwRawValue[1]’, ‘arwRawValue[2]’ and ‘arwRawValue[3]’ Example: Read the actual value of coil 17 Settings: eFunctionCode: ReadFunctionCodes.FC01_ReadCoils wRegisterAddr = 17 eExpectedType = EXPECTED_TYPE.TYPE_BYTE ( = 8 bit ) Due to the fact that at least 16 consecutive bits are always transmitted, the actual values of coils 17 - 32 are requested. After successful transmission, the actual values are available in the variable ‘arwRawValue[0]’: ‘arwRawValue[0].0’: actual value of coil 17 ‘arwRawValue[0].1’: actual value of coil 18 ‘arwRawValue[0].2’: actual value of coil 19 ‘arwRawValue[0].3’: actual value of coil 20 ‘arwRawValue[0].4’: actual value of coil 21 ‘arwRawValue[0].5’: actual value of coil 22 ‘arwRawValue[0].6’: actual value of coil 23 ‘arwRawValue[0].7’: actual value of coil 24 ‘arwRawValue[0].8’: actual value of coil 25 ‘arwRawValue[0].9’: actual value of coil 26 ‘arwRawValue[0].10’: actual value of coil 27 ‘arwRawValue[0].11’: actual value of coil 28 ‘arwRawValue[0].12’: actual value of coil 29 ‘arwRawValue[0].13’: actual value of coil 30 ‘arwRawValue[0].14’: actual value of coil 31 ‘arwRawValue[0].15’: actual value of coil 32
