Query limits.
Modbus protocol imposes following restriction on amount of data that can be read or write at once. "The quantity of registers to be read, combined with all other fields in the expected response, must not exceed the allowable length of Modbus messages: 256 bytes." – Modicon Modbus Protocol Reference Guide PI–MBUS–300 Rev. J This means that Modbus message must not exceed 256 octets in size. In Modbus over TCP, device address and CRC (3 octets) are traded for 6 octet header and 1 octet unit identifier, which gives 4 octets less to store values. Theoretical maximal amounts of values for given Modbus register types, that can be queried within a single message, are defined by constants below, however particular PLCs may impose further restrictions.

Reply handler.

Reimplemented in cutehmi::modbus::AbstractClient.

◆ handleRequest()

virtual void cutehmi::modbus::AbstractDevice::handleRequest ( const QJsonObject & request )

protectedpure virtual

Handle request.

This function acts as request handler, that derived class must implement. Internally request() function creates request object and passes it to request handler of derived class. Request object is added to pending requests queue. Derived class should start processing request. Once request completes derived class is expected to prepare reply and call handleReply() function. Otherwise it has to remove request from queue by calling takePendingRequest() function and emit requestCompleted() signal.

Parameters

request request object containing request header and payload.

Implemented in cutehmi::modbus::AbstractServer, and cutehmi::modbus::AbstractClient.

QJsonObject cutehmi::modbus::AbstractDevice::readFileRecordSubrequest	(	quint16	file,

Generate read file record subrequest.

Helper function that creates JSON object for readFileRecord() function.

Parameters

file	file number.
address	starting address.
amount	amount of registers to be read.

Returns: JSON object representing read file record subrequest.

See also: readFileRecord().

◆ ready()

bool cutehmi::modbus::AbstractDevice::ready ( ) const

Get readiness status.

Indicates whether device is ready for handling requests.

Returns: readiness status. If device is ready to handle requests function returns true, otherwise it returns false.

signal

◆ request()

void cutehmi::modbus::AbstractDevice::request	(	Function	function,
		QJsonObject	payload,
		QUuid *	requestId = `nullptr`
	)

Modbus function request.

Parameters

function	Modbus function code.
payload	request payload. Payload is specific to each function code. Typically it is more convenient to use one of the helper slots (requestXYZ()) rather than prepare raw payload.
requestId	request id. If not `nullptr`, function will set pointee to generated request id before handling the request.

◆ requestCompleted

void cutehmi::modbus::AbstractDevice::requestCompleted	(	QJsonObject	request,
		QJsonObject	reply

signal

◆ requestDiagnostics()

void cutehmi::modbus::AbstractDevice::requestDiagnostics	(	AbstractDevice::DiagnosticsSubfunction	subfunction,
		quint16	data,
		QUuid *	requestId = `nullptr`
	)

Diagonistics request.

Convenient function that prepares payload and calls request() with FUNCTION_DIAGNOSTICS function code.

Parameters

subfunction	diagnostics function.
data	data to be passed to diagnostics function.
requestId	request id. If not `nullptr`, function will set pointee to generated request id before handling the request.

◆ requestFetchCommEventCounter()

void cutehmi::modbus::AbstractDevice::requestFetchCommEventCounter ( QUuid * requestId = nullptr )

Report slave id request.

Convenient function that calls request() with FUNCTION_FETCH_COMM_EVENT_COUNTER function code.

Parameters

requestId request id. If not nullptr, function will set pointee to generated request id before handling the request.

◆ requestFetchCommEventLog()

void cutehmi::modbus::AbstractDevice::requestFetchCommEventLog ( QUuid * requestId = nullptr )

Report slave id request.

Convenient function that calls request() with FUNCTION_FETCH_COMM_EVENT_COUNTER function code.

Parameters

requestId request id. If not nullptr, function will set pointee to generated request id before handling the request.

◆ requestMaskWriteHoldingRegister()

void cutehmi::modbus::AbstractDevice::requestMaskWriteHoldingRegister	(	quint16	address,
		quint16	andMask,
		quint16	orMask,
		QUuid *	requestId = `nullptr`
	)

Mask write holding register request.

Convenient function that prepares payload and calls request() with FUNCTION_MASK_WRITE_HOLDING_REGISTER function code. As a result a holding register is modified according to the following formula: holdingRegister[address] = (holdingRegister[address] AND andMask) OR ( orMask AND ! andMask).

Parameters

address	address of the holding register to mask.
andMask	mask to be used as AND mask.
orMask	mask to be used as OR mask.
requestId	request id. If not `nullptr`, function will set pointee to generated request id before handling the request.

◆ requestReadCoils()

void cutehmi::modbus::AbstractDevice::requestReadCoils	(	quint16	address,
		quint16	amount = `1`,
		QUuid *	requestId = `nullptr`
	)

Read coils request.

Convenient function that prepares request payload and calls request() with FUNCTION_READ_COILS function code.

Parameters

address	starting address.
amount	number of coils to query. Note that Modbus specification expects it to be 16 bit unsigned value, so 65535 is maximal number of coils that can be queried at once (Modbus address range 0-65535 contains 65536 addresses). Modbus message size imposes further restriction - see query limits.
requestId	request id. If not `nullptr`, function will set pointee to generated request id before handling the request.

◆ requestReadDiscreteInputs()

void cutehmi::modbus::AbstractDevice::requestReadDiscreteInputs	(	quint16	address,
		quint16	amount = `1`,
