■Operation of the wave output step execution function
The wave output step execution function operates as follows.
Step action wave output request
(Un\G188)
CH1 Wave output status monitor
(Un\G401)
CH1 Wave output step execution
moving amount (Un\G482)
CH1 Wave output current address
monitor (Un\G436, 437)
Analog output value
By turning 'Step action wave output request' (Un\G188) OFF (0)  ON (1), change the status to Wave output step execution
in progress. By setting the value in 'CH1 Wave output step action movement amount' (Un\G482) during wave output step
execution, control moves to the address of the wave data to be subjected to the output test. For the value in 'CH1 Wave
output step action movement amount' (Un\G482), set the amount by which to move it from the address of the current wave
data.
After the movement is completed, 'CH1 Wave output step action movement amount' (Un\G482) changes to No movement (0)
and the destination wave data is output as analog data.
The range where the movement is enabled by 'CH1 Wave output step action movement amount' (Un\G482) is determined by
both setting values of the wave pattern start address and the wave pattern data points. The movable range is as follows.
Wave pattern
to
Start address
If a value equal to or larger than "Wave pattern data points" is set in 'CH1 Wave output step action movement amount'
(Un\G482), the value of wave pattern data points will be used for processing.
■Execution of the wave output step execution function
To use the wave output step execution function, the wave output function needs to be initialized beforehand. For initializing
the wave output function, refer to the following.
Page 209 Initializing the wave output function
[Changing the status to wave output step execution]
Change the wave output status to Wave output step execution in progress by using the following procedure.
1.
Turn Step action wave output request (Un\G188) OFF (0)  ON (1).
2.
Check that the CH Wave output status monitor for all channels have changed to Wave output step execution in
progress (3).
To perform the wave output step execution, check the 'Latest error code' (Un\G0) and the ERROR LED to confirm that no
error has occurred. Then, change 'Step action wave output request' (Un\G188) (0) from OFF (0) to ON (1). Unless the wave
output parameter setting is set within the set range on all D/A conversion enabled channels, the wave output step execution
cannot be performed on any channels.
