## Description



This example demonstrates how to use the Industrial Edge System Apps to read data from a PLC, preprocess it and push it to the cloud.



### Overview



  

  



The **OPC UA Connector** is used to read status data from the PLC in a 100ms cycle and publishes it to the **Databus**.



The **Flow Creator** is used to read the data and calculate the flow in m3/min and publish it back to the **Databus**.



The **Cloud Connector** then reads this preprocessed data and publishes it to the **AWS Cloud**.



### General task



To set up this example, the industrial Edge Apps Databus, OPC UA Connector and Cloud Connector have to be configured. 

Furthermore an AWS IoT Devices has to be created.



## Requirements



### Used components



- Industrial Edge Management (IEM) v2.0.1-1 

  - Databus Configurator V2.3.2-2

  - Common Connector Configurator V1.9.1-1

  - Cloud Connector Configurator V1.17.0-3

- Industrial Edge Virtual Device (IEVD) 1.16.1-1 

  - Databus V2.3.1-2

  - Common Import Converter V2.1.0-2

  - IIH Registry Service V1.9.0-0

  - IIH Essentials V1.10.0

  - OPC UA Connector V2.0.1-0

  - Cloud Connector V1.14.0-2

  - Flow Creator V1.17.0-2

  

- PLC: CPU 1511 FW 2.8.3



### Further requirements



- The Bottle filling example project is loaded to a PLC on which a OPC-UA server is running

- The minimum publishing interval and sampling interval of the OPC UA server of the PLC is set to 100ms

- The following Apps are installed on the Industrial Edge Device (IED): *Databus, Common Import Converter, IIH Registry Service, IIH Essentials, OPC UA Connector, Cloud Connector and Flow Creator* 

- The following Apps are installed on the Industrial Edge Management (IEM) in the *Application Manager* Platform: *Databus Configurator, Common Connector Configurator and Cloud Connector Configurator* 

- Access to AWS with permission to create IoT Devices and policies



### TIA Project



The used TIA Portal project can be found in the [miscellaneous repository](https://github.com/industrial-edge/miscellaneous) in the tank application folder and is also used for several further application examples:



- [Tia Tank Application](https://github.com/industrial-edge/miscellaneous/tree/main/tank%20application)



## Installation



Please refer to the [Installation](./docs/Installation.md) documentation.



## Usage



To publish preprocessed data of the PLC to the cloud, the Flow Creator is used to receive the data published to the Databus by the OPC UA Connector, preprocess it and publish the result to the topic the Cloud Connector is listening to.



With the following flow, the filling level of the tank is used to calculate the flowrate of the tanks filling which is then published to the AWS IoT thing.



Configure the Industrial Edge System Applications according to the [Installation](./docs/Installation.md) documentation and deploy the provided [flow](./src/iotGateway-flow.json) into the Flow creator. 



Before deploying the flow enter the user credentials configured in Databus in the MQTT-Node.

Start the flow and the PLC Program. The calculated flowrate is now visible in the aws IoT management console:
