Description, parameter values
Reading procedure is completed (DONE = TRUE)
This output always has to be considered together
with output ERR.
The following applies:
● DONE = TRUE and ERR = FALSE: Reading
completed. The data set has been stored begin-
ning at the defined input SM.
● DONE = TRUE and ERR = TRUE: An error
occurred while reading the data set. Output
ERNO indicates the error number.
Error occurred (data segment could not be read)
This output always has to be considered together
with output DONE. The following applies if an error
occurred: DONE = TRUE and ERR = TRUE. Output
ERNO indicates the error number.
Error number Ä [4].
Output ERNO indicates an error number. This output
always has to be considered together with the out-
puts DONE and ERR.
The SF_FLASH_READ operation may take quite a
long time since the safety CPU user program is pro-
cessed with higher priority. Output ERNO indicates
that the function block has started the execution
(0x0FFF = BUSY).
During this phase, the outputs ERR and DONE are
set to FALSE.
