! This task configures three channels:
40
!
Channel 0 monitors the level of a liquid in a tank
45
!
Channel 1 monitors the startup pressure of a process
50
!
Channel 2 monitors the operating pressure of a process
55
!
If any configuration fails, SHUTDOWN@ is set
60
!
65
! This task checks for alarms once per second.
