The DA364/DA374 provides a 4W I/O data for storing 4 point analog output data (DA364/
DA374 base register). The data is output by batch I/O or direct output from the controller.
The DA364/DA374 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 DA364/DA374 is abnormal and calibration for each channel when
calibrating offset or gain (DA364/DA374 internal expansion memory). The MREAD
command is used to read these data.

(1) Analog output
Analog output data for
each channel.
Read by batch I/O or
direct input from the
controller.
Same as 4W content of base
register.
(2) Status
Contains DA364/DA374
module settings and error
information.
Read with MREAD
command from the
controller.
(3)(4) Calibration
Contains the offset/gain
when calibrated.
Read with MREAD
command from the
controller.
Note: Use this area as
read only and do not write
into it.
