3.4.14 Redundant system area

This area is used for the redundant system support function.
For details on the redundant system support function, refer to Section 4.8.
POINT
Order of assignment
(1) The corresponding bits of the Redundant system 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. (
