Wave output data can be created easily by using "Create Wave Output Data" of the engineering tool. This data can be saved
in the CSV file or file register (ZR) of the CPU module.
For details on the function block (FB) for registering wave output data and executing wave output, refer to the following.

■Feature of the file register (ZR) and CSV file to which wave data is saved
• When saving data to the file register (ZR), wave output data is held in the CPU module even after powering off or resetting
the CPU module.
• When saving data to the CSV file, wave output data can easily be reused for the D/A converter module of other
programmable controller systems by simply copying the CSV file.
