Editing Local Variables

User variables and local variables can be used in the storage of counters, calculations, and input
signals. The data format is the same as that of user variables. As shown in the following table, the letter
L is affixed to the variable number to indicate a local variable.

Local variables differ from user variables in the following four ways:
• Used in One Job Only
With user variables it is possible to define and use one variable in multiple jobs, but local
variables are used only in the one job in which they are defined, and cannot be read from
other jobs. Accordingly, local variables do not affect other jobs, so it is possible to define a
variable number (such as LB001) separately in different jobs, and use it in different ways
in each of these jobs.
Job 1
• Able to Use Any Number of Variables
The number is set in the JOB HEADER window. When the number is set, the area for the
value is saved in memory.
