(1) The corresponding bits of the Temporary slave reservation area are assigned
in order of the parameters set in GX Configurator-DP (in order of the FDL
address).
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)) in
GX Configurator-DP, the order of the assigned DP-Slaves is changed.
After modifying parameters, check 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. (
