15 CPU Load Limits
As all microprocessors, the two processors of the DDU 10 have limited capacities. The cur-
rent load of the processors can be monitored using the channel "cpu_load_001" or
"cpu_load_002". When configuring your device, please make sure the used CPU load is in
a save range below 100 %.
Bosch recommends a maximum CPU load of 85 % (averaged). Exceeding this limit might
result in the DDU 10 not being able to fulfill its required measuring/logging/display tasks
or even in crashing and rebooting.
Main factors influencing the CPU load are:
– Number and complexity of math channels
– Number and complexity of conditions
– CAN traffic on both CAN lines
– Display configuration, especially displaying pictures
– Logger configuration (total logging rate [kB/s], conditional measurement rates)
To help respecting the limit of 85 % CPU load, the DDU 10 creates an error memory entry.
To trigger this error entry, the CPU load must exceed the limit for 5 minutes without inter-
ruption.
When being confronted with this error memory entry (see 'Error info' in RaceCon) or when
being confronted with DDU 10 resets due to complex configuration setups, please con-
sider reducing the demands on the DDU 10 adapting the influencing factors mentioned
above.
