only: Pointer to the
device name on which
the rmware le is
located.
Path E_OpenPath PATH_GENERIC

variable of this type
selects generic or 1 of
the TwinCAT

system
paths on the target
device.
VAR_OUTPUT
Done BOOL The rmware le has
successfully been
transferred. Carry out a
power cycle on the SAB
to enable the new
rmware.
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.
Table 6.77 DD_UpdateFirmware_SAB
6.5.8.9 DD_ReadDcLinkPower_SAB
This function block provides the value of the actual DC-link
power (see chapter 8.4 Object 0x2001: DC-link Related
Values) if Enable is set. Valid is TRUE when the data-output
Power is valid. If Enable is reset, the data loses its validity
and all outputs are reset, regardless of whether new data is
available.
The output data is available immediately.
