== How Live Values Work ==
Live values are special properties without a value that is persisted in the database. Instead, they get their current value frequently from a live value server, including a measurement quality indicator and a read timestamp, among other details. Live values can be used to display trends and current values (e.g., sensor values) from dynamic sources like process control systems (e.g., via OPC-UA).
With the UBIK.Interface.Module.OPCUA plugin, {{UBIK}} will detect that there is a live value server and it will host a live value data service, supplying our "cooling unit" objects with their current "temperature" values.
== Implementing Live Values in {{UBIK}} Studio ==
First of all, download the UBIK.Interface.Module.OPCUA from the ''Augmensys Realease Portal/Plugins'' and copy them into the injections folder from your {{UBIK}} Studio as well as in the injection folder of the Web Service.
