GlobalReals Parameter

Default Value: 256

Minimum Value: 0

Maximum Value: 500000000

Units: None

Type: int

The GlobalReals parameter specifies the total number of IEEE-754 double-precision floating-point variables ($rglobal[]) that are available to, and shared by, all tasks on the controller. You can use these variables to share information between tasks.

Each global double-precision variable uses 8 bytes of available memory. When this parameter has a nonzero value, controller memory is allocated for each global variable.

IMPORTANT: It might not be possible to allocate the maximum number of global double-precision variables on all systems or configurations because of limited memory. If the memory allocation does not complete correctly, a memory allocation error will occur.

If memory resources are low, you can decrease the value of this parameter to release memory for other Automation1 features.
