(4) Input data start address area (for mode 3) (Un\G22784 to Un\G22908)
When the operation mode is Communication mode (mode 3), the start address (buffer
memory address) for each DP-Slave's input data is stored in this area.
Creating a sequence program utilizing the Input data start address area (for mode 3)
(Un\G22784 to Un\G22908) allows address specification of the Input data area
without consideration of the input points for each DP-Slave.
Information of 125 modules is stored in the Input data start address area (for mode 3)
in the same order for each module.

(5) Output data start address area (for mode 3) (Un\G22912 to Un\G23036)
When the operation mode is Communication mode (mode 3), the start address (buffer
