OneWire.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
OneWire.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
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
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
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
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
