Example of programming for reading out the DP diagnostic list
FB209 "DIAG-LIS" requests the diagnostic list from the CP with the special
service HDB A-NR. 209 and enters it in DB209 from DW4 onwards (incl.
acknowledgment).
Function block FB 209 signals that the job has been done by resetting the
assigned trigger bit "ANST".
Function block FB 209 with the corresponding data block 209, for use in a
CPU of the S5-115U series is in the STEP 5 file DIAG@@ST.S5D on the
COM/Application examples diskette.
11.7.4 Request Single DP Station Diagnostic Data
With the special service "single DP station diagnostics", you can request DP
slave-specific diagnostic data from a slave connected to the bus.
The diagnostic data of a single DP slave, can be requested from a DP
slave at any time regardless of the "New diagnostic data" message in the
DP diagnostic list .
En entry in the DP diagnostic list indicating that new diagnostic data exist is
deleted when the diagnostic data are read.
