42 Programmer’s Guide
Displaying Current Memory Allocations
From the SYS prompt, you can view memory allocations for
programs, PLCs, communication stream buffers, global variables,
and aliases. The controller displays the default memory allocation for
only programs. For all other items, you must allocate memory to
them (PLCs, global variables, and aliases), or change the default
memory allocation (communication stream buffers).
From the PROG prompt, you can view the memory allocations for
local variables, strings, and arrays.
To view current memory allocations, use the DIM command.
Displaying Free Memory
You can view the free memory for the system or a specific program
or PLC. For more information, see the MEM command in the ACR
Command Language Reference.
To view free memory, use the MEM command.
Deleting Programs and PLCs
Before you can clear memory allocation for programs or PLCs, you
must erase the program or PLC program being stored. You can
delete all programs or a specific program or PLC. For more
information, see the NEW command in the ACR User’s Guide.
To erase all programs and PLCs, use the NEW ALL command.
Clearing Allocated Memory
You can clear memory at the system or program level, returning the
controller to factory set memory allocations.
NOTE: The CLEAR command behaves differently at the system and
program levels. For more information, see the CLEAR
command in the ACR Command Language Reference.
To free the allocated memory, use the CLEAR command.
