# Statistics

### Statistics

Two basic, common statistical functions are available for a Statistics block.

- The Single Input Over Time option automatically keeps up with the minimum and maximum value of a selected variable, since the time the monitoring was started.
- The Multiple Inputs option will use a list of up to 16 input values and calculate the Maximum, Minimum, Median and Average values.

**Statistics is NOT a background task. **It must be executed every time you want to take a sample.

### Single Input Over Time

- The Input is the Tag that you want to monitor.
- The Maximum is the Tag where you want to store the maximum value of the selected input.
- The Minimum is the Tag for storing the minimum value.

### Multiple Input Statistics

Up to 16 input Tags can be selected.

The Multiple Input Statistics block can be set up to determine and calculate any of:

- Maximum value
- Minimum value
- Median value
- Average value

If you do not select a Tag for any of the statistical operations, this program block will simply skip that function.

You must select at least one statistical operation.
