PROFINET-RT: How much memory does the Profinet stack use?

[#1]

The memory footprint depends on aspects such as the size of the application, the used submodule(s), number of slots.

An example of the memory footprint is described below:

ARM Cortex-M3 Platform with GOAL 2.12

 

Memory Footprint (01_simple_io)

220 058 bytes of readonly code memory
69 079 bytes of readonly data memory
375 422 bytes of readwrite data memory (contains GOAL HEAP, thus not used 100%)

Memory Footprint (13_pnio_snmp)

275 816 bytes of readonly code memory
78 228 bytes of readonly data memory
420 413 bytes of readwrite data memory (contains GOAL HEAP, thus not used 100%)

GOAL heap (01_simple_io / 13_pnio_snmp)

heap usage id(GOAL_ID_TASK): 252 Bytes
heap usage id(GOAL_ID_TGT): 17004 Bytes
heap usage id(GOAL_ID_INSTANCE): 148 Bytes
heap usage id(GOAL_ID_MA_NVS): 88 Bytes
heap usage id(GOAL_ID_MI_NVS): 16867 Bytes
heap usage id(GOAL_ID_MAIN): 124 Bytes
heap usage id(GOAL_ID_DRV_NVS): 12 Bytes

heap usage id(GOAL_ID_LOCK): 624 Bytes
heap usage id(GOAL_ID_LOG): 5164 Bytes
heap usage id(GOAL_ID_CM): 8284 Bytes
heap usage id(GOAL_ID_QUEUE): 49960 Bytes
