KL6WriteRegisters

The function block KL6WriteRegisters writes data to one or several registers of a serial Bus Terminal KL6xxx.

Inputs

VAR_INPUT
  Execute          : BOOL;
  Mode             : ComSerialLineMode_t;
  pComIn           : POINTER TO BYTE;
  pComOut          : POINTER TO BYTE;
  SizeComIn        : UINT;
  pRegisterList    : POINTER TO ARRAY[0..63] OF ComRegisterData_t;
  SizeRegisterList : UINT;
END_VAR

Name	Type	Description
Execute	BOOL	A rising edge at the Execute input starts the read process. The register list must be initialized before the function block is triggered. This means the register numbers and register content must be entered in the list.
Mode	ComSerialLineMode_t	The Mode input specifies unambiguously which serial hardware is being used.
pComIn	POINTER TO BYTE	Universal pointer to the input variable of the process data for the serial hardware (data types: KL6inData, KL6inData5b, KL6inData22b, PcComInData). The pointer is assigned with the ADR() function.
pComOut	POINTER TO BYTE	Universal pointer to the output variable of the process data for the serial hardware (data types: KL6outData, KL6outData5b, KL6outData22b, PcComOutData). The pointer is assigned with the ADR() function.
SizeComIn	UINT	Size of the input process image of the serial hardware being used. The size is determined and assigned with the SIZEOF() function.
pRegisterList	POINTER TO ARRAY[0..63] OF ComRegisterData_t	Start address of a register list. The start address can be determined with ADR(register list). The register list must be initialized before the function block is triggered. This means the register numbers and register content must be entered in the list.
SizeRegisterList	UINT	Size of the register list in bytes. The size can be determined via SIZEOF (register list). The list may have between 1 and 64 entries.

Outputs

VAR_OUTPUT
  Done       : BOOL;
  Busy       : BOOL;
  Error      : BOOL;
  ErrorID    : ComError_t;
END_VAR

Name	Type	Description
Done	BOOL	The Done output becomes TRUE when the function has been carried out without error.
Busy	BOOL	The Busy output becomes TRUE in response to rising edge at Execute, and remains TRUE for as long as the function block is performing its function.
Error	BOOL	This output Error goes TRUE as soon as an error occurs.
ErrorID	ComError_t	The ErrorID output provides an error code when an error occurs.
