Description
Reference to the SAB.
See chapter 6.5.8.1 SAB_REF.
Get the value of the
parameter continuously while
enabled
Index of the object to be read.
Sub-index of the object to be
read.
Pointer to a buffer where the
read data will be placed (use
ADR() function).
Maximum size of the read
data (size of the provided
buffer given in byte; use
SIZEOF() function)
The function block has a valid
output.
The function block is not
finished and new output
values are to be expected.
An error has occurred within
the function block.
Error identification and
instance identifier.
See chapter 6.5.2.3 Error
Indication.
SDO abort code if there is an
error. Available in the list of
constants: SdoAbortCodes.
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.
