3.5.6 Creating the Program that Calls the Function
The user function is completed when the graphic representation and body program of the
function have been created. As with the standard system functions, user functions can be
called from any parent, child, or grandchild drawing or any other user function.
Functions can be called from a drawing or from within the program of another user function
by using the following procedure. For details on the operation methods, refer to the
MP9
†† Machine Controller User’s Manual Ladder Programming (SIEZ-C887-1.2).
1. Input the function name using the FSTART instruction.
Example: Input FSTART, Enter Key, TEST, Enter Key.
The previously defined graphic representation of the function will be displayed.
2. Use the FIN instruction to create the input data program.
Provide input data for the function inputs and address inputs.
3. Use the FOUT instruction to create the output data program.
Example: I/O data is provided for the graphic representation as shown in the following
illustration.
