Wave data
Wave data is a series of chronologically arranged digital input values to be output as analog data. Up to 80000 points of wave
data are available. Wave data is designed to be registered in 'Wave data registry area' (Un\G10000 to Un\G89999).
Wave pattern
The wave output function allows you to select a desired data points from the registered wave data and set a wave pattern for
each channel. Set the wave pattern with the following items.
Setting item
Wave pattern start address setting
Wave pattern data points setting
An error occurs if the value obtained by subtracting 1 from the sum of the setting values of the wave pattern start address
setting and the wave pattern point setting exceeds the last buffer memory address (Un\G89999) of the wave data registration
area. Error code 1D9H is stored in 'Latest error code' (Un\G0), 'Error flag' (Un\G69, b15) turns on, and the ERROR LED
turns on.

Description
Sets the start address of the wave pattern that is output for each channel. D/A conversion is performed
sequentially from the digital input values of the set buffer memory address, and they are output as analog data.
Sets the data points of the wave pattern that is output for each channel. From the wave pattern start address, the
wave data for the set data points is D/A-converted and output as analog data.
