The AD368 provides an 8W I/O data for storing 8 point analog input data (AD368 base
register). The data is read by batch I/O or direct input from the controller.
The AD368 also provides other various data, but they need not be referenced except for
special cases.
Examples of these various data are status for referencing the error state when the AD368
is abnormal and calibration for each channel when calibrating offset or gain (AD368
internal expansion memory). The MREAD command is used to read these data.

(1) Analog input
Analog input data for
each channel.
Read by batch I/O or
direct input from the
controller.
Same as 8W content of base
register.
(2) Status
Contains AD368 module
settings and error
information.
Read with MREAD
command from the
controller.
(3)(4) Calibration
Contains the offset/gain
calibration when
calibrated.
Read with MREAD
command from the
controller.
Note: Use this area as
read only and do not write
into it.
