4.2.3 Auto refresh function
When the auto refresh parameters are set, the relation between the CPU devices and
the refresh-target devices (remote input (RX), remote output (RY), remote registers
(RWr, RWw), link special relay (SB) and like special register (SW)) is as shown on the
system configuration example below.

device station
The relation between the CPU devices and the devices of each remote station is as
shown below. Note that this figure is illustrated based on the following setting: remote
input (RX) is set to X400, remote output (RY) is set to Y400, remote registers (RWr,
RWw) are set to W0 and W100 respectively, link special relay (SB) is set to SB0000
and link special register (SW) is set to SW0000.
