Hello PI community,


Starting a gasturbine happens in a sequence of steps each with a different timespan, the starting sequence is not connected to the PI system.

is there a timer that can count back so i get an alarm when the step takes to long?


i like to make a sequence with 6 different timers witch can be started and give an alarm when they reach 0


somting like this 


purge   5 minutes    whe 0 alarm 

start       1 minute

runup    3 mniutes

grid connection 1 minute

to baseload 10 minutes
