STEP 7
"DP Slave Diagnos- Show slave diagnostics in plain
tics" tab text on the
face
SFC 13 Read slave diagnostics data,
"DPNRM_DG" 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 there-
fore check the RET_VAL pa-
rameter after every execution
of SFC 13.
SFC 59 "RD_REC" Read data records of S7 diag-
nostics (store in the data area
of the user program)
SFC 51 "RDSYSST" Read SSL partial lists. Call
SFC 51 in the diagnostic inter-
rupt 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
