SFC 13
"DPNRM_DG"
Read slave diagnostics data,
i.e., save them to the data area
of the user program
It is possible that the busy bit
will not be set to "0" if an error
occurs while SFC 13 is being
processed. You should
therefore check the RET_VAL
parameter after every
execution of SFC 13.
see System and Standard
Functions
reference manual. For the
structure of other slaves, refer
to their descriptions.
SFC 59 "RD_REC" Read data records of S7
diagnostics (store in the data
area of the user program)
See System and Standard
Functions
reference manual
SFC 51 "RDSYSST" Read SSL partial lists. Call
SFC 51 in the diagnostic
interrupt with SSL ID
W#16#00B3 and read the SSL
of the slave CPU.
SFB 52 "RDREC" For DPV1 slaves
Read the data records of S7
diagnostics, i.e., store in the
data area of the user program
SFB 54 "RALRM" For DPV1 slaves:
Read interrupt information
within the associated interrupt
