IDEC MICROSmart FC6A Series Ladder Programming Manual page 577

Operation Example
The following ladder program will execute the UMACRO instruction when main program input I0000 is turned on. When the
UMACRO instruction is executed, user-defined macro name 0 will be executed.
A0001 will operate as I0001 in the user-defined macro because A1 of the UMACRO instruction has been set to I0001. Therefore,
the MOV instruction will be executed when I0001 is turned on.

Note: You can save time and effort in writing similar ladder programs and creating new ladder programs by turning a ladder program into a user-
defined macro.
Note: The UMACRO, JMP, JEND, MCR, MCS, LCAL, LJMP, LRET, LABEL, DJNZ, and END instructions cannot be used in a user-defined macro.
