3 Basic System Operation
3.5.6 Creating the Program that Calls the Function
3-28
In the table, address input register AW00000 is allocated to MA00300. That is, registers
AW00000, AW00001, and so on, used inside the TEST function correspond to external
registers MA00300, MA00301, and so on. Therefore, if a given value in AW00000 is
stored inside the function, this value will be stored in MA00300.

4. Creating a motion program that calls the function.
User functions can also be called from motion programs.
Example: The user functions shown in Table 3.11 would be called from a motion pro-
gram using the following coding:
„ Conditions for referencing a user function from a motion program
• The first item of output data must be bit data.
This output will be the completion signal for moving to the next motion command.
