Event Detection Example: Energy Spikes

In this example, we'd like to point out when any of our machines are running at more than 100% of their rated power.

MotorCurrent - PercentageThe amount of current, relative to nameplate maximum

Initial Layout

To begin with, we have one Event Output node, one ARDI Point, a Numeric Constant and a Condition node.

Step 1: Capture When Current > 100%

First, we need to choose the right property to read from.

Next, we set the threshold we want to use to determine if we're over the maximum current draw.

This logic will now highlight whenever the current on the machine exceeds 100%.

Step 2: Capturing Event Data

Often, well want a little more context about our events. The Metadata node allows us to capture specific values from when the event began.

If we wanted to know what the current actually was when the event triggered, we would…

This allows us to spot small events where our machine has been using more power than expected.

We continue to extend this example in our advanced example.
