5.2 Using Variables
This section explains how to use variables.
5.2.1 System Variables (S Registers)
J
Overview
System variables (S registers) are provided by the MP-series Machine Controller system. They
can be used to read system error information, the operation status, and so on. S registers are
global variables that can be used in any motion program. For details, refer to the Corresponding
Machine Controller User’s Manual: Design and Maintenance.
J Description
S registers are designated as follows:
SB000000 to SB01023F
SW00000 to SW01023
SL00000 to SL01023
SF00000 to SF01023
The variable number is expressed as a decimal. When bits are specified, the bit number is ex-
pressed in hexadecimal.

Programming Examples
D Bit Designation
OB000010 = SB000402|SB000403;
D Integer Designation
MW00100 = SW00041;
D Double Integer Designation
ML00100 = SL00062;
The system registers (S) are used exclusively for reading. If they are written to, system operations cannot be guar-
anteed.
