Dynamic RAM Memory
The QuickPanel
+
Operator Interface is equipped with dynamic RAM (DRAM). Part of the
DRAM is reserved for the Windows operating system and is not accessible by user
applications. The remaining memory is split between two functions: an object store for
temporary file storage and the main memory for running programs.
Typically, compressed programs stored in flash memory are expanded and moved to
DRAM for execution. Temporary storage of program variables or data files is also
provided by DRAM. Any data stored in DRAM is not retained through a power cycle or
reboot.
The split between program memory and storage memory can be adjusted as necessary to
make more room for one or the other, depending on your specific application needs. For
example, if you find that an application is short of memory, alter the DRAM memory
allocation from the System Properties window.
Caution
Setting the Program Memory too low may prevent
additional applications from starting, or may cause
currently running applications to fail due to lack of
memory.
Setting the Storage Memory too low may prevent the
saving of files into the object store portion of the file
system, which may also cause application failures.
