Getting Started – Data Route
Use OAS Data Route when you need to transfer data from one OAS Tag value to another Tag, MQTT Broker, Azure IoT Data Hub or IoT Edge. The Tags can be local or remote. When a Tag is set as a Destination values will be written to the Data Source defined in that Tag.
View the following video for a demonstration of transferring a value from one tag to another.
Step 1 – Create the driver see the appropriate data source in the Data Sources Section (If using Classic OPC or Calculations as a source skip this step)
Step 2 – Create the source Tag. Refer to Configure – Tags for additional information on tag configuration.
Step 3 – Select the Target Tab
Step 4 – On the target tab check Enable Write to Target
Step 5 – Select the TargetType (Tag, OPC, Azure IoT, Azure IoT Edge, or MQTT )
Step 6 – Select the destination for the value to be sent.
If Tag is selected then select Browse and select the desired OAS tag.
Value is the most commonly used Variable. See Tag Variables for a complete list of all Variables possible.
Note: You can also browse remote tags on other services to transfer data over a network.
If OPC Item is selected select browse and select the OPC server and Item
If Azure IoT or MQTT is selected then select Browse and select the desired Driver
Step 7 – Enter the desired Deadband in the Float Deadband field. Enter 0 for no deadband.
Step 8 – If you want to specify a desired update frequency for the target check Write Continuously and enter the desired frequency. If Write Contentiously is unchecked the the target will be updated every time the source tag changes.
