Trip

 Control of a Trip Alarm

Controls a Trip Alarm with setting of the Trip level, hysteresis and delay time for ON and OFF condition. If the
input value is higher than the high trip level (MAX) for a time longer  than Ton, the bits selected in the output
mask will be forced to 1. If the input value is lower than the low trip level (MIN) for a time longer than Toff, the
bits selected in the output mask will be forced to 0.
It is possible to use this Function Block to execute the operation “A>B”: set the trip levels with the same value
and the delay times Ton and Toff = 0.
NOTE:  the  output  status  is  updated  at  each  execution  of  the  Function  after  the  end  of  the  delay  time:  it  is
suggested to insert this Function Block in a zone of the Program continuously executed.

The graph

(Fig.4.1)

shows the working of a Trip alarm that goes on if the input signal is higher than 100°C for at

least 2 seconds and goes off if the input signal is lower than 90°C for at least 5 seconds.
