Overview of Variables

Name
Global variables
Position Data Data to indicate positions.
System vari- Status of MC Unit such as operating modes,
ables error logs, etc.
Global general Can be accessed from all the tasks, and
variables used for Communicating data between oper-
ations and tasks.
Input variables Status of the input from CPU Unit or
MECHATROLINK-II devices.
Output variables Outputs for CPU Unit or MECHATROLINK-II
are executed from a program.
Variables exclusively for tasks
Task variables Can be used only in each task, and are used
as workspace, etc. during operations.
Note
Rules for Writing
Variables
Make sure to turn the MC Unit power OFF once, and then ON again after sys-
tem parameters have been transferred. The unit parameters and machine
parameters will not change unless the power is turned back ON.
The parameters that are marked 'Yes' on the immediate updating columns can
be changed without the power OFF/ON.
• A part of motion task parameters
• Axis − speed parameters
• A part of Axis − position parameters
• A part of Axis − machine parameters
There are six types of MC Unit variables as shown below:
• System variables
• Global general variables
• Input variables
• Output variables
• Position data
• Task variables
Purpose
(1) For Position Data, see 4-4 Position Data (page 93).
(2) For System variables, see 4-5 System Variables (page 96).
(3) For Input variables and Output variables, see 4-6 I/O Variables
(page 143).
(4) CAM Data will not be treated as a variable.
Use the following format to write variables.
Put "#" in front of variables.
