Description
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

BOOL Network is initialized and
ready for communication.
ReadyFor-
PowerOn
BOOL SAB is ready to enable the
power on the lines (mains
voltage is applied on the
SAB).
PowerOn BOOL TRUE shows that the power is
switched on at the output
lines.
SabWarning BOOL Warning(s) present on the
SAB.
SabError BOOL Error(s) present on the SAB.
Table 6.73 DD_ReadSabInfo_SAB
6.5.8.5 DD_ReadSabError_SAB
This function block presents general SAB errors unrelated
to the function blocks (for example, overtemperature in
the SAB). The output SabErrorID gives the last error that
occurred in the SAB (see chapter 9.3.2 Warnings and
Alarms).
The output data needs to be read from the device and is
therefore not immediately available.
