This chapter describes how to configure the Recipe function and its operation on the Touch.
1.1 How the Recipe Function is Used
The Recipe function batch writes values prepared in advanced to specified devices and batch reads the values for
specified devices according to the state of a device. Use this function for situations such as configuring the initial
values of an external device when the Touch starts running. The data used by the Recipe function is called recipe
data for the data saved in internal memory, a recipe file for data saved to the external memory, and recipe values for
the values written to devices that were saved in recipe data and recipe files.
The Recipe function can perform the following functions.
• Batch write the recipe values saved in internal memory to devices when a value of device changes from 0 to 1
• Batch write the recipe values saved on the external memory to devices when a value of device changes from 0 to 1
• Batch read value of a device and save them to the external memory as a recipe file when a value of device changes
from 0 to 1

in the external memory. For example, save the values of devices before the power is turned off and write
them the next time the power is turned on.
