Data Handling

The following functions/function blocks for data handling operations are available:

Function Short description

*_TO_BUF Copies elementary data types from a variable, an array or elements of a user-defined structure to a byte stream

BIT_TEST Reads the value of a single bit in a bit string

BUF_TO_* Copies elementary data types from a byte stream to a variable, an array or elements of a user-defined structure

GET_BIT Reads the value of a single bit in a bit string

GET_CHAR Extracts one character out of a string

GET_LSB Reads the value of the less significant BYTE of a bit string

GET_MSB Reads the value of the most significant BYTE of a bit string

I_BIT_IN_* Inverts a single bit in a bit string.

INVERT_BIT Inverts a single bit in a bit string

MEMORY_COMPARE Compares two memory areas

MEMORY_COPY Copies data from one runtime system data area to another runtime system data area (indexed copying)

MEMORY_SET Sets a given memory area

PACK Converts data to a proprietary exchange format

PARITY Checks if the number of set bits is even or odd

R_BIT_IN_* Resets a single bit in a bit string.

RESET_BIT Resets a single bit in a bit string

S_BIT_IN_* Sets a single bit in a bit string.

SET_BIT Sets a single bit in a bit string

SET_LSB Writes a value on the less significant BYTE of a bit string

SET_MSB Writes a value on the most significant BYTE of a bit string

SIZEOF Determines the size of a variable in the controller memory

STRING_COPY Copies each character of an input string to a buffer

SWAP Exchanges the most and the less significant BYTE of a bit string

UNPACK Converts data from the proprietary exchange format generated by the PACK function block back to the original format
