Output points

Output points send data from Data Archive through an interface to any external data source capable of receiving inputs, such as a PLC or a third-party database. Each interface has its own requirements for configuring output points. For UniInt-based interfaces, outputs are triggered as opposed to occurring on a regularly-scheduled basis.

There are two ways to trigger new values sent to output points:

• Specify an input point to trigger the output point. The output point will update every time the input point receives a new value.

• Manually write a new value to the snapshot of the output point itself, triggering output to the destination.

If the output point is configured correctly, the new value is written to the destination when the output point is successfully updated. A success status indicates that the output point has been updated; however, this does not guarantee that the external data source was updated. To verify data source updates, create a corresponding input point and check its value.

If the interface does not successfully receive a value, it records a digital state that describes the error.
