dead_channel
Purpose:
Monitor variables and events to detect if they are not being updated and initiate specified actions.
Enter:
-
dead_channel &
Where:
-
N/A
Example:
-
dead_channel &
Notes:
This process is normally launched by the “sys_start” task and requires no command line arguments.
The specification file “/cell/dead_chan_specs” must exist else the process will terminate.
The process may be manually launched if it terminates when launched by “sys_start”.
The methods can be specified in the /cell/dead_chan_specs specification file. A maximum of 256 specifications is allowed.
An example is shown below:

“if( key_switch && ( RPM > 150[rpm] ) ) then TRUE else FALSE”
variable eval_period type action_type watchdog_delay
cmp_in_p 10[sec] EU_COMP ABORT 30[sec]
cmp_ot_p 15[sec] RAW_COMP ABORT 30[sec]

or the following for a standard deviation evaluation
