====Rate Node====

This is a [[module_count|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** [[analytic_modules|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).
