MotionSuite™ Series Machine Controller Programming Manual Chapter 5: Variables (Registers)

5-2

5.1 Outline

In this section, an outline of the variables is described.

5.1.1 Variable Overview

In motion programs the variables can be used to describe values instead of directly

giving the values. When using variables, the motion program uses the values stored

in an area reserved for variables.

! Variable (Register) Type

Motion programs can use the following 7 types of registers (described in the following

table) as variables. The S, M, I, O, and C registers are called global variables which can be

used in both motion programs and ladder programs. The # and D registers are called local

variables which are only capable of referencing within an individual program. However,

the local variables are secured in program memories; they take space from the programs.

SSystem Register

SB, SW, SL,

SFnnnnn

SW00000

~SW01023

Registers prepared in the system. The register

number nnnnn is displayed with a decimal.

When the system starts, the

SW00000~SW00049 is cleared to 0.

Used by all kinds of programs

M Data Register

MB, MW,

ML,

MFnnnnn

MW00000

~MW32767

Registers used for the I/F between each DWG.

The register number nnnnn is displayed with a

decimal.

I Input Register

IB, IW,

IL, IFhhhh

IW0000

~IW07FF

Registers used for I/O module input data. The

hexadecimal. If a register number is after C000,

it is used for interface with the servo

monitoring parameters.

O Output Register

OB, OW,

OL,

OFhhhh

OW0000

~OW07FF

Registers used for I/O module output data. The

hexadecimal. If a register number is after C000,

it is used for interface with the servo setting

parameters.

C Constant Register

CB, CW,

CL,

CFhhhhh

CW00000

~CW4095

Registers that can be referenced only by a

program. The register number nnnnn is

displayed with a decimal.
