(5) Access units
The following table explains the number of device points (access units) that can be
accessed in a single process when sampling a programmable controller CPU's device
values.
When the access units are lower than the number of sampled device points, the
module sampled the device values in the same sequence scan.
When the access units exceed the number of sampled device points, device values
are sampled over multiple sequence scans, so there is a possibility of data separation
(the mixture of the current device value and the old device value) occurrence.
If data separation must be prevented, set the number of devices sampled at one time
to less than the access units, or set the module to use high speed data sampling.

*1: Current value data when "Synchronize create trigger and current value data" is not checked.
When checked, refer to the access units for the specified data sampling method (high speed or
general data sampling).
*2: The high speed data sampling function can be used only when using a programmable controller
with a serial number whose first five digits are '11012' or higher.
