Rate Node
This is a counter node. It takes a rate of change or consumption, and produces a total for the given time-frame.
This is often used when you want to count how much of something is being produced or consumed per day, shift or other time window.
NOTE: Optrix usually suggest that totalisation should be done in the field or PLC, as these provide the best possible accuracy. This node will only produce approximate results.
This node is only available in counter modules.
Example
| Input Value | Count | |
|---|---|---|
| 05:00 | 25m/min | 0 |
| 05:01 | 22 | 22 |
| 05:02 | 20 | 44 |
| 05:03 | 25 | 69 |
| 05:04 | 30 | 99 |
| 05:05 | 20 | 119 |
Inputs
Input #1 is a number. This value - plus a time multiplier - are added to the counter.
Options
The Time Multiplier specifies how many seconds are represented by each unit of the measured value coming in.
For example, an hourly rate should have a time multiplier of 3600 (60 seconds & 60 minutes = 3600).
