Yokogawa 414 Batch Controller - Manual (Page 9)

3. OPERATION
The Model 414A Batch Controller uses a low power CMOS microprocessor to
perform all control functions and calculations.
The instrument is fully programmable with all operating parameters and
calculation constants user programmable. (See Section 5 entitled "Calibration"
for information on programming.) All parameters and constants are stored in a
non-volatile memory which retains data without battery backup for a minimum
of 10 years.
A block diagram of the instrument is shown below.
