Scope Of Data And Save Area - Omron SYSMAC FH Series User Manual

Scope of Data and Save Area

Necessity of referring
to this manual
In macro customize functions, many types of data can be used as needed for the objective, and variables and
macro functions can be used to set and acquire data.
The areas where data settings and acquisition can be executed and the areas where data are saved vary
depending on the type of data.
By using data types appropriately for the objective of the program, macro customize functions enable the
creation of programs that are easy to change and maintain.
Data Scope
The locations from which data can be set and acquired are limited; data cannot be set or acquired from any
location. This limited location is called a "scope", and data can only be set and acquired from within the scope
defined for that data type.
Data scopes that can be used with the macro customize functions are as follows.
Scope
Within a processing unit
Within a communication command

Within a scene
