WriteDataToFileRegisterBank

Write data to file register bank 1 or 2

This instruction reads the number of words specified by DataNumberOfWords from DataStartAddress and writes it to the File Register Bank 1 or 2 as specified by BankNumber beginning with BankOffset.

Parameters

Input

BankNumber (INT): Specifies the bank number
BankOffset (INT): Specifies the bank number offset
DataStartAddress (WORD, INT, UINT): Specifies start address of data to be written to File Register Bank
DataNumberOfWords (INT): Specifies number of word units to be written to File Register Bank

Remarks

With this function you cannot write data to the FL area (File Register Bank 0), i.e., the variable applied at DataStartAddress must not be located in the FL area.

Example

POU header

All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.

	VAR
		awProcessDataToStore: ARRAY [0..10] OF INT:=[-111,111,222,333,444,555,666,777,888,999,1100];
		awProcessDataToGet: ARRAY [0..10] OF INT:=[11(0)];
		bStoreData: BOOL:=FALSE;
		bGetData: BOOL:=FALSE;
	END_VAR

POU body

If bStoreData changes from FALSE to TRUE, the entire data unit variable awProcessDataToStore (a DUT containing 11 elements) is filled with the data from File Register Bank 2 BankOffset 1000.
