Obtaining the memory configuration and setting the allocation

Getting the available memory on the AS
The memory available in the AS depends on the type of CPU and with older CPUs also on the
number of memory modules used. The work memory is split. Half is in a fixed code area and
half in a fixed data area.
Proceed as follows to determine the amount of memory currently available:
1. Right click on the CPU in the SIMATIC Manager and select "PLC -> Module Information"
2. Select the "Memory" tab. In the displayed dialog, you can recognize the current
configuration of the data and code memory of the selected CPU.
Storage of recipe logic
The recipe logic is stored on the AS in data blocks of the type "MemIDB64" in the data area
of the work memory. The data blocks are saved in the CFC chart "@ASB_Mem".
Allocation of work memory
The figure shows the dialog for individually setting the allocation of work memory with data
blocks for storing of recipe logic.
Blocks cannot be created and fitted during the AS runtime.
