The Random Generator Tag provides a randomly generated
data source for I/O Data Point Tags.
The Random Generator Tag is a license free tag. You can create any number of these tags without restriction.
The Random Generator Tag supports the configuration properties of the Core Tag plus these properties:
| Property | Type | Version | Description |
|---|---|---|---|
| UpdateInterval | TIME | 3.12 | The interval between each update. See Interval and Offset for information on how timed activities are scheduled. |
| UpdateOffset | TIME | 3.12 | The offset added to the UpdateInterval to get the actual update time. See Interval and Offset for information on how timed activities are scheduled. |
| NominalRange | UINT | 3.12 | The maximum deviation (positive or negative) of the RandomWalk property from the NominalValue. |
| NominalValue | UINT | 3.12 | The initial value of the RandomWalk property and the center of its range of values. |
| StepValue | UINT | 3.12 | The maximum change (positive or negative) of the RandomWalk property at the next update. |
The Random Generator Tag supports the data properties of the Core Tag, plus these properties:
| Property | Type | Description |
|---|---|---|
| SawTooth | UINT | A saw tooth value varying between 0 and 65535. |
| SineWave | UINT | A sine wave value varying between 0 and 65535. |
| CosineWave | UINT | A sine wave value varying between 0 and 65535. The value of this property is 90 degrees out of phase with respect the to SineWave property. |
| RandomWalk | UINT | A random value. |
| RandomBit | BOOL | A random bit value. |
The Random Generator Tag does not support any tag commands.
