Turn off CH Output enable/disable flag.
Decide an address (Address A) of Wave data registry area
from which the next wave is to be output.
Change the value in Address A to a digital value to be output.
Set CH Wave output step action movement amount to a
value obtained from "Address A - Current address"
No
Has the wave output step action move
been completed?
Yes
Turn on CH Output enable/disable flag.
Check that a digital value set in Address A is properly output
in analog.
Is a value output in analog properly?
Yes
Yes
Is it necessary to repeat the analog output test?
No

Example of testing analog output in CH1.
Turn off 'CH1 Output enable/disable flag' (Y1).
The analog output value becomes the offset value.
Example 1
When 'CH1 Wave output current address monitor' (Un\G436, Un\G437)
is 10100, and Address A is 10110
1: Change Wave data registry area (Un\G10110) to the digital value to be
output.
2: Set 'CH1 Wave output step action movement amount' (Un\G482) to 10
(= 10110 - 10100).
Example 2
When 'CH1 Wave output current address monitor' (Un\G436, Un\G437) is
10100, and Address A is 10095
1: Change Wave data registry area (Un\G10095) to the digital value to be
output.
2: Set 'CH1 Wave output step action movement amount' (Un\G482) to -5
(= 10095 - 10100).
When the value set in 'CH1 Wave output step action movement amount'
(Un\G482) has been accepted, 'CH1 Wave output step action movement
amount' (Un\G482) changes to No movement (0).
Turn on 'CH1 Output enable/disable flag' (Y1).
The analog output value changes from the offset value to the wave data
value of Address A.
Check that the analog output value is a proper one using a measuring
instrument such as a tester.
No
Turn off CH Output enable/disable flag.
Change the value in Address A to the digital value to be
output.
Turn on CH Output enable/disable flag.
