27.2.3.10 Configurable Memory Objects in the Work Memory
With some CPUs, the size of objects such as local or the diagnostic buffer can be set in HW
Config. If, for example, you reduce the default values, a larger section of the work memory is made
available elsewhere. The settings for these CPUs can be displayed in the "Memory" tab of the
Module Information ("Details" button).
After the memory configuration has been changed and downloaded to the programmable
controller, you must perform a cold restart in order for the changes to become effective.
