IServerCommand (ITF) ¶ INTERFACE IServerCommand EXTENDS __SYSTEM.IQueryInterface Interface to handle the commands arriving on the server side Methods: Exec Structure: Exec (Method)
spiMaster.transferExt (METH) ¶ METHOD transferExt : BOOL This method is used to transfer data via SPI InOut: Scope Name Type Initial Comment Return transferExt BOOL Input pabyTxBuffer POINTER TO ARRAY [0..255] OF BYTE pointer to send buffer pabyRxBuffer POINTER TO ARRAY [0..255] OF BYTE pointer to receive buffer udiLen UDINT 3 length to transfer uiDelayus UINT 5 delay in µs udiSpeedHz UDINT 0 send clock in Hz; if 0, _diMaxSpeed is used
i2c.AfterReadInputs (METH) ¶ METHOD AfterReadInputs : INT This method can be overloaded by extending FBs. It is used to read in the inputs of the device in the beginning of the cycle. Always including a call of the base implementation with super^.AfterReadInputs() In the base implementation, the body of the FB is called. InOut: Scope Name Type Return AfterReadInputs INT
i2c.BeforeWriteOutputs (METH) ¶ METHOD BeforeWriteOutputs : INT This method can be overloaded by extending FBs. It is used to write the outputs to the device at the end of the cycle. Always including a call of the base implementation with super^.BeforeWriteOutputs() In the base implementation, the body of the FB is called. InOut: Scope Name Type Return BeforeWriteOutputs INT
IServerCommand.Exec (METH) ¶ METHOD Exec Elaboration of a command in Server side: command is elaborated and next send the answer to client InOut: Scope Name Type Comment Input uiCmd UINT Command code pDataRcv __XWORD Pointer where are the data received diSizeRcv DINT Data received Output pDataTrs __XWORD Pointer to the data to transmit back diSizeTrs DINT Data to transmit uiAns UINT Answer code iError INT Error to transmit back
i2c.read (METH) ¶ METHOD read : DINT This method is used to directly read nBufferLen bytes from the CharDevice. InOut: Scope Name Type Comment Return read DINT Number of bytes that have actually been read Input pbyBuffer POINTER TO BYTE pointer to area, where the bytes are copied nBufferLen UDINT number of bytes to read
i2c.read8 (METH) ¶ METHOD read8 : USINT This method is used to read the data byte of one register The function therefore first writes the register number and then reads one byte. InOut: Scope Name Type Comment Return read8 USINT data content Input usiRegister USINT register to read
RDT_Base (FB) ¶ FUNCTION_BLOCK ABSTRACT RDT_Base Base FB for TCP activities in Redundancy Data Transfer Properties: IPAddress Port RcvTimeout TrsTimeout Methods: FlushRec ReceiveBytes SendBytes SetTLSContext Structure: FlushRec (Method) IRdtProt IPAddress (Property) Port (Property) RcvTimeout (Property) TrsTimeout (Property) ReceiveBytes (Method) SendBytes (Method) SetTLSContext (Method)
i2c.readregister (METH) ¶ METHOD readregister : DINT This method is used to read a number of data bytes starting from a certain register The function therefore first writes the register number and then reads the defined number of bytes. InOut: Scope Name Type Comment Return ReadRegister DINT Number of bytes that have been actually read Input usiRegister USINT register number, where to start reading pbyBuffer POINTER TO BYTE pointer to buffer where to store the read data nBufferLen UDINT number of bytes to read
i2c.write (METH) ¶ METHOD write : DINT This method is used to directly write nBufferLen bytes to the CharDevice. InOut: Scope Name Type Comment Return write DINT Number of bytes that have actually been written Input pbyBuffer POINTER TO BYTE Pointer to the buffer that contains the data nBufferLen UDINT number of bytes to write
