List,
Can anyone tell me how and what to set on a REALM block to make the ROC
work? In the past I have set up on a test bed and used a RAMP block to
test but it never works as I think it should.
I want an alarm to be generated when the temperature goes up 500 DegF in
5 minutes. The temp normally operates at a constant value but if it
increases by the 500 Degrees within 5 minutes then I want an alarm.
In the past I have accomplished this by building two AIN blocks and
changing the "period" on one and sending these to a REALM block (MEAS &
DEVSPT). One problem I have now is there is no period with a 5 minute
execution. Besides if I could configure the REALM correctly I would
only have to create one block instead of two.
Anyone with any ideas?
