Programming Topic (Controller Category)
Use the Programming topic to configure global variables and programming units. This topic and its
Global Variables Module
The Global Variables module lets you specify the total number of global variables available to, and shared by, all tasks on the controller. Each global variable type uses a different quantity of available memory. A global double-precision variable or global integer variable uses 8 bytes. A global string variable uses 256 bytes.
You can use global variables to share strings or information between tasks. For an example of how global variables communicate between tasks, see the Global Variables example program.
For more information about the global variables that you can specify, see the parameters that follow:
Units Module
The Units module lets you specify the programmed velocity for dependent axes and different units for dominant axes. You can also map G-code commands G71 (Metric) and G70 (English) to Primary and Secondary unit modes.
For more information, see the parameters that follow:
