Local
Variables
As well as user variables, local variables can be used for 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 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.
•
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.
