Table 76. CR1000 SRAM Memory
Use
----------------------------------
Variables & Constants
Comments
Stores variables in the user program. These values may persist through powerup,
recompile, and watchdog events if the PreserveVariables instruction is in
the running program.
----------------------------------
Final-Storage Data Tables
Final Storage is given lowest
priority in SRAM memory
allocation.
Stores data resulting from CR1000 measurements. This memory is termed "Final
Storage." Fills memory remaining after all other demands are satisfied.
Configurable as ring or fill-and-stop memory. Compile error occurs if
insufficient memory is available for user-allocated data tables.
----------------------------------
Communications Memory 1
Construction and temporary storage of PakBus® packets.
----------------------------------
Communications Memory 2
Constructed Routing Table: list of known nodes and routes to nodes. Routers use
more space than leaf nodes because routes to neighbors must be remembered.
Increasing the PakBusNodes field in the Status table will increase this allocation.
