IRdtProtClient.ExecCommand (METH) ¶ METHOD ExecCommand Execution of a command in Client side: command is sent to server InOut: Scope Name Type Comment Input uiCmd UINT Command pDataTrs __XWORD Pointer to the data to transmit diLen DINT Data length to transmit pDataRcv __XWORD Pointer where to write data received diSizeRcv DINT Maximum size of the above buffer Output xDone BOOL Operation done, with or without errors error INT Error uiAns UINT Answer diLenRcv DINT Data length received
OneWire.Initialize (METH) ¶ METHOD Initialize : UDINT This method can be overloaded by extending FBs. It is called once during initialization phase, before the PLC goes into “run”. Always including a call of the base implementation with super^.Initialize(wModuleType, udiInstance, pConnector) Typically, parameter values from the configuration are read here. InOut: Scope Name Type Return Initialize UDINT Input wModuleType UINT dwInstance UDINT pConnector POINTER TO IoConfigConnector
OneWire.Operational (PROP) ¶ PROPERTY Operational : BOOL This property has to return TRUE, when the device is configured and running
IRdtProtServer (ITF) ¶ INTERFACE IRdtProtServer EXTENDS IRdtProt Interface for Redundancy Data Transfer Server Properties: Active , inherited from IRdtProt Busy , inherited from IRdtProt Enable , inherited from IRdtProt Error , inherited from IRdtProt ErrorCode , inherited from IRdtProt IPAddress , inherited from IRdtProt Port , inherited from IRdtProt RcvTimeout , inherited from IRdtProt TrsTimeout , inherited from IRdtProt Methods: RegisterCommand CyclicCall , inherited from IRdtProt SetNewCertificate , inherited from IRdtProt Structure: RegisterCommand (Method)
spi.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
spi.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
IRdtProtServer.RegisterCommand (METH) ¶ METHOD RegisterCommand : INT It registers the interface to handle the command arrive in the server InOut: Scope Name Type Return RegisterCommand INT Input itfServerCommand IServerCommand
spi.transfer (METH) ¶ METHOD transfer : BOOL This method is used to transfer data via SPI InOut: Scope Name Type Initial Comment Return transfer 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
spi.transferExt (METH) ¶ METHOD transferExt : BOOL This method is used to transfer data via SPI. In contrast to the method ‘transfer’ one can specify the communication clock. 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
spi.Operational (PROP) ¶ PROPERTY Operational : BOOL This property has to return TRUE , when the device is configured and running
