Memory Spaces under
e!RUNTIME
The memory spaces in the controller under
e!
RUNTIME
have the following sizes:
•
Program and data memory:
60 Mbytes
•
Input data:
64 kbytes
•
Output data:
64 kbytes
•
Flags:
24 kbytes
•
Retain:
104 kbytes
•
Function block limitation:
12 * 4096 bytes = 48 kbytes
9.3.1
Program and Data Memory
The program (also code) and data memory has a size of 60 Mbytes.
This space has already been requested in the system after a successful program
download and can be fully utilized.
The memory space is dynamically divided up into program and data space.
9.3.2
Function Block Limitation
Together with the data memory to be used by the application, memory is required
for the individual program function blocks in the system.
The size of the administration space is calculated from the function block
limitation * 12 (i.e., 4096 * 12).
The actual size of the main memory required in the system for data is the sum of
global program and data memory and function block limitation memory.
9.3.3
Remanent Memory
A total of 128 kbytes of remanent memory is available for the IEC-61131
application.
The remanent section is subdivided into the flag area (memory) and the retain
area.
