InOut:

Scope	Name	Type	Initial	Comment
Input	xEn	BOOL	TRUE	Enable / disable communication ( TRUE = enabled )
Input	byUnitId	BYTE	0	Address of the device
Input	InputValue	__SYSTEM.AnyType		Input variable to determine the states of the coils (FC15) (BOOL, BYTE, ARRAY OF BOOL, ARRAY OF BYTE)
Input	xUpdateSetp	BOOL	FALSE	Update of setpoint values (on every rising edge )
Input	xResError	BOOL	FALSE	Reinitialization of the outputs ‘eErrorCodeCom’ and ‘eErrorCodeDev’ to the error-free state (on every rising edge)
Inout	ModbusClient	ModbusClientBase		Client of the device
Output	wCoilAddrFb	WORD	0	Feedback - start address of the coil(s) for the Modbus telegram (0 - 65535)
Output	wNumberOfCoilsFb	WORD	0	Feedback - number of coils to write (range: 1 - 64, wNumberOfCoils <= InputValue.diSize)
Output	wArrayStartIndexFb	WORD	0	Feedback - relative array element with the first coil to be written (0 - (InputValue.diSize-1)) (only for data type ARRAY OF BOOL and ARRAY OF BYTE)
Output	eInputValueDataType	SIMPLE_WRITE_COILS_FC15_DATA_TYPE	SIMPLE_WRITE_COILS_FC15_DATA_TYPE.INVALID_TYPE	Internal classification of the data type of the variable with the coil states (0 = invalid, 1 = BOOL, 2 = BYTE, 3 = ARRAY)
Output	xInputValueValid	BOOL	FALSE	Validity of the variable at input 'InputValue' (FALSE = not valid, TRUE = valid)
Output	xErrorFreeDataTransmission	BOOL	FALSE	Status of the data transmission (FALSE = faulty, rising edge = error-free)
Output	xAlarm	BOOL	FALSE	General fault ( TRUE = fault )
Output	xAlarmCom	BOOL	FALSE	General fault - communication ( TRUE = fault )
Output	eErrorCodeCom	ModbusErrorCode	ModbusErrorCode.NO_ERROR	Error code - communication ( 0 = no error )
Output	eErrorCodeDev	SIMPLE_WRITE_COILS_FC15_ERROR_CODE	SIMPLE_WRITE_COILS_FC15_ERROR_CODE.NO_ERROR	Error code - device (0 = no error)
Output	xBusy	BOOL	FALSE	Communication indicator ( TRUE = communication )
Input Const	wArrayStartIndex	WORD	0	Relative array element with the first coil to be written (0 - (InputValue.diSize-1)) (only for data type ARRAY OF BOOL and ARRAY OF BYTE)
Input Const	wNumberOfCoils	WORD	1	Number of coils to write (range: 1 - 64, wNumberOfCoils <= InputValue.diSize)
Input Const	wCoilAddr	WORD	1	Start address of the coil(s) for the Modbus telegram (0 - 65535)
Input Const	tTimeUpdateSetp	TIME	TIME#0ms	Update interval for operations influenced by the input 'xUpdateSetp'
