Kick the processor watchdog to avoid reset.
None (Main library). (See Section 2.3, “Licensed Features”.)
A watchdog is a timer that causes a processor reset when the timer exceeds a maximum duration. By kicking the watchdog on a periodic basis, the processor reset never occurs. A simple scheme to utilise the watchdog kicks the watchdog on a periodic basis. A more complex scheme might kick the watchdog only if the software appears to be performing the correct functionality (for instance, if two independent measurements of the same quantity show a large discrepancy).
The psc_KickWatchdog block causes the processor watchdog timer to clear thus avoiding a reset. Each ECU has a fixed watchdog duration.
| Target ECU | Watchdog duration | Maximum kick period |
|---|---|---|
| M110, M220, M221, M250, M460, M461 | [~419, ~838] milliseconds [a] | 200 milliseconds |
| M670 | [~508, ~1016] milliseconds [a] | 200 milliseconds |
[a] The range reflects the configuration of the processor's watchdog, which uses two time out periods before resetting the processor. | ||
If no psc_KickWatchdog block is present in the model then the watchdog will be kicked by the platform automatically at the maximum period for the target ECU.
