Use the following procedure to save a function block definition as a file and
use it in a program for another PLCs.
1. Select the function block that you want to save and save it as a function
block definition file (*.cxf).
2. Open the other PLC's project and open/read the function block definition
file (*.cxf) that was saved.
3. Insert the function block definition in the program when creating the new
program.

In the CX-Programmer Ver. 5.0, each function block definition can be com-
piled and checked as a program. We recommend compiling to perform a pro-
gram check on each function block definition file before saving or reusing the
file.
