Constructor Details

StaticDataMapModbusConnection

public StaticDataMapModbusConnection(net.solarnetwork.util.IntShortMap data)

Constructor.

Parameters:

data - the starting data

Method Details

writeWords

public void writeWords(ModbusWriteFunction function,
 int address,
 int[] values)

Description copied from interface: ModbusConnection

Write unsigned 16-bit word values to 16-bit Modbus registers.

All the elements in values will be truncated to 16-bits and then stored in Modbus registers.

Specified by:

writeWords in interface ModbusConnection

Overrides:

writeWords in class ModbusConnectionSupport

Parameters:

function - the Modbus function code to use

address - the 0-based Modbus register address to start writing to

values - the unsigned 16-bit values to write

writeString

public void writeString(ModbusWriteFunction function,
 int address,
 String value,
 Charset charset)

Description copied from interface: ModbusConnection

Write a string as raw byte values to registers.

Specified by:

writeString in interface ModbusConnection

Overrides:

writeString in class ModbusConnectionSupport

Parameters:

function - the Modbus function code to use

address - the 0-based Modbus register address to start writing to

value - the string value to write

charset - the character set to interpret the bytes as

writeWords

public void writeWords(ModbusWriteFunction function,
 int address,
 short[] values)

Description copied from interface: ModbusConnection

Write 16-bit word values to 16-bit Modbus registers.

Specified by:

writeWords in interface ModbusConnection

Overrides:

writeWords in class ModbusConnectionSupport

Parameters:

function - the Modbus function code to use

address - the 0-based Modbus register address to start writing to

values - the 16-bit values to write

writeDiscreetValues

public void writeDiscreetValues(int[] addresses,
 BitSet bits)

Description copied from interface: ModbusConnection

Write values of a set of "coil" type registers, via a BitSet.

This uses a Modbus function code 5 request, once for each address in addresses. Each address at index i corresponds to the value of bit at index i. Thus bits 0 to addresses.length - 1 are used.

This method is required but deprecated to preserve backwards compatibility.

Specified by:

writeDiscreetValues in interface ModbusConnection

Overrides:

writeDiscreetValues in class ModbusConnectionSupport

Parameters:

addresses - the Modbus register addresses to start writing to

bits - the bits to write, each index corresponding to an index in addresses

writeBytes

public void writeBytes(ModbusWriteFunction function,
 int address,
 byte[] values)

Description copied from interface: ModbusConnection

Write raw byte values to registers.

Specified by:

writeBytes in interface ModbusConnection

Overrides:

writeBytes in class ModbusConnectionSupport

Parameters:

function - the Modbus function code to use

address - the 0-based Modbus register address to start writing to; values.length * 2 16-bit registers will be written

values - the byte values to write
