Enable BOOL FALSE Get the value of the
parameter continuously while
enabled
Index UINT 0 Index of the object to be read.
Subindex USINT 0 Sub-index of the object to be
read.
pBuer UDINT 0 Pointer to a buer where the
read data will be placed (use
ADR() function).
BuerSize UDINT 0 Maximum size of the read
data (size of the provided
buer given in byte; use
SIZEOF() function)
VAR_OUTPUT
Valid BOOL The function block has a valid
output.
Busy BOOL The function block is not
nished and new output
values are to be expected.
Error BOOL An error has occurred within
the function block.
ErrorInfo DD_ERROR_ISD51x Error identication and
instance identier.
See chapter 6.5.2.3 Error
Indication.
AbortCode DWORD SDO abort code if there is an
error. Available in the list of
constants: SdoAbortCodes.
DataLength UDINT Length of the read data [Byte].

6.5.8.13 DD_WriteParameter4_SAB
This function block asynchronously writes general objects
of up to 4 bytes to the object dictionary of the SAB. For
the index and the sub-index of the parameters, see
chapter 8 SAB Parameter Description.
The data needs to be written to the device asynchronously
and is therefore not available in the SAB immediately.
