READ_UINT32

Reads a UINT32 parameter of the IO-Link device and switches the bytes to high endian.

Inputs

Name	Type	Description
nIndex	WORD	Index of the IO-Link parameter 0 for the entire structure
nSubindex	BYTE	Subindex of the IO-Link parameter 0 for the entire structure
pData	PVOID	Address of the buffer that is to receive the read data. The programmer himself is responsible for dimensioning the buffer to a size that can hold LEN bytes. The buffer can be a single variable, an array or a structure, whose address can be found with the ADR operator.
