1.2 Features of Ladder Programming for MP2000-series Machine Controllers
1.2.2 Program Modules

1.2.2 Program Modules
The main program can be separated into modular units to suit different processing requirements, such as child draw-
ings, grandchild drawings, and functions, to make the program easier to read.
1.2.3 Programming Complicated Numeric Operations
Complicated calculations written over several lines can be written easily within a single EXPRESSION instruction.
Variables, structures, and basic functions, such as those for sine and cosine calculations, can be programmed using
familiar C-like expressions.
You can display the current value inside expressions in the same way as you can for other ladder language instructions.
