Writing data to a file register (ZR) or CSV file
Write wave output data created in "Create Wave Output Data" to a file register (ZR) or CSV file.
• Data unnecessary for control such as "Wave pattern name", "Comments", and "Wave details setting" is not
written to the file register (ZR) or the CSV file. Saving the wave data and the parameter setting of the wave
output function using the [Save Wave Output Data to File] button before writing them is recommended.
• When the setting of "Create Wave Output Data" is written in the project of the remote head module, the data
cannot be written into the file register (ZR). Allow data to be written into the CSV file.
■Writing data to a file register (ZR)
When writing the data to the file register (ZR), set the capacity of the file register (ZR) for the number of required data points.
For the setting procedure, refer to the following.

■Writing data to a CSV file
When writing data to a CSV file, store the CSV file to an SD memory card.
1.
Click the [Write Data for Memory Card] button of the "Create Wave Output Data" window.
2.
Set the save destination and the file name, then click the [Save] button.
3.
Click the [Close] button in the "Create Wave Output Data" window to close the window.
4.
Store the CSV file to an SD memory card. Then install the SD memory card to the CPU module.
Some oscilloscopes or pulse generators can output the input wave or output wave to the CSV file. To output
the wave with the wave output function by using the CSV file data, convert the data format into the one
described in the following manual. In addition, convert the fractional value into the integer because the
fractional value is unavailable in the wave output function.
