The channel names depend on the name used for the module, in this example GPS_Trig-
ger. Each trigger has a distance and a trigger channel with the abbreviation m for macro
or p for parameter based. The trigger channel will be set to 1, when the lowest distance to
the trigger point is detected. For the macro-based trigger, the stored latitude and longit-
ude values can be seen with the channels.
Measurement label Function
name_lat interpolated gps latitude
name_long interpolated gps longitude
name_ptrig_1..10 trigger output of parameter based trigger (n)
name_pdist_1..10 distance to trigger of parameter based trigger (n)
name_mtrig_1..10 trigger output of macro based trigger (n)
name_mdist_1..10 distance to trigger of parameter based trigger (n)
name_macro_lat_1..10 stored latitude for macro based trigger (n)
name_macro_long_1..10 stored longitude for macro based trigger (n)

9.8 CPU Load Limits
As all microprocessors, the two processors of the C 80 have limited capacities. The current
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 C 80 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
– Logger configuration (total logging rate [kB/s], conditional measurement rates)
To help respecting the limit of 85 % CPU load, the C 80 creates an error memory entry. To
trigger this error entry, the CPU load must exceed the limit for 5 minutes without interrup-
tion.
When being confronted with this error memory entry (see ‘Error info’ in RaceCon) or when
being confronted with C 80 resets due to complex configuration setups, please consider
reducing the demands on the C 80 adapting the influencing factors mentioned above.
