Order of assignment
(1) Data are assigned to the Diagnostic information area (for mode 3) in the order
of the parameters set in GX Configurator-DP (in the order of FDL addresses).
The actual order of assignment can be checked in Address information area
(for mode 3) (Un\G22528 to Un\G22777) or in "Documentation of I/O-
Mapping" of GX Configurator-DP.
(2) When parameters have been modified (deletion or addition of DP-Slave(s))
on GX Configurator-DP, the buffer memory is reassigned.
After modifying parameters, review the sequence program.
If some DP-Slaves are expected to be connected to the network in the future,
setting them as Reserved stations in the parameter setting eliminates the
need to check the sequence program. (
(3) The information in Diagnostic information area (for mode 3) (Un\G23072 to
Un\G23321) is not cleared even if the problem occurred on the DP-Slave has
been solved.
To clear the information in Diagnostic information area (for mode 3)
(Un\G23072 to Un\G23321), turn ON the Diagnostic information area clear
request signal (Y02).
