Constructor Details

ModbusWriteRegisterRequestBlueprint

public ModbusWriteRegisterRequestBlueprint(int slaveId,
 int reference,
 ModbusRegisterArray registers,
 boolean writeMultiple,
 int maxTries)
                                    throws IllegalArgumentException

Construct coil write request with many bits of data

Parameters:

slaveId - slave id to write to

reference - reference address

registers - register(s) to write

writeMultiple - whether to use ModbusWriteFunctionCode.WRITE_MULTIPLE_COILS over ModbusWriteFunctionCode.WRITE_COIL. Useful with single register of data.

maxTries - maximum number of tries in case of errors, should be at least 1

Throws:

IllegalArgumentException - in case data is empty, writeMultiple is false but there are many registers to write.
