Secured 32-bit data

When the following conditions, 1) and 2) are satisfied in the CC-Link network, 32-bit data in remote registers
(RWr/RWw) between a programmable controller CPU and a master/local station can be secured.
1) Access starts from a remote resister (RWr/RWw) address of an "even number".

*Because the start address on the remote resister side is an "odd address", new and old data may be mixed in 16-bit
(1-word) units.
2) Access by the program must be made in units of even points.
