logic.hub

What’s explained:

1. The terminal inventory
2. Orientation in the Logic Editor - Nodes
3. Orientation in the Logic Editor - Workspace
4. Orientation in the Logic Editor - Info column
5. Creating an example flow

1. The terminal inventory

Click on the images to enlarge!
- After successfully logging on to the web interface of the logic.hub you will see in the left column the tab Terminal inventory.
- Click on ADD W&T TERMINAL, or on the to add devices from other manufacturers.

- Then enter the device article number, e.g. 57730 as well as the device name. This can be found either on the web interface of the W&T device under Communication Paths and then under MQTT, or using the last 6 places of the MAC address: wut-(last 6 places of the MAC). Now click on "Determine terminals" and save. Your W&T device is now linked to the logic.hub. Don’t forget to activate MQTT under the communication channels and enter the IP address of the broker (logic.hub).

- To link third-party devices, simply click on the plus symbol

- All you have to do is enter the name, an optional description and the MQTT topic and fill in the remaining fields to get started.

It is essential to include each device in the terminal inventory, otherwise you will not be able to work with these devices on the logic.hub.

2. Orientation in the Logic Editor - Nodes

- You can access the editor via the corresponding link on the overview page of your logic.hub.
- On the left-hand side of the editor, you will find a list of nodes that are categorized according to their functions.
- To use a node, simply drag and drop it onto your workspace.
- To obtain a short description, drag the node onto the workspace; a short description now appears on the right.
- By clicking on the node, you can also adjust it to your requirements on the right-hand side.
- Depending on the type of node, many other properties can be configured.

3. Orientation in the Logic Editor - Workspace

- The workspace is located in the center of the logic editor and is used to create your flows.
- New pages can be added using the plus symbol Create new page in the middle of the workspace.
- The page can be edited in the right-hand column, e.g. to change the name.

4. Orientation in the Logic Editor - Info column

The information column on the right-hand side shows you information on the elements you have selected, depending on the work step.
You will also find two additional symbols in the information column:
The error log can alert you to possible errors or problems.
The check mark shows you whether the Runner is connected.

5. Creating a sample flow

The logic.hub requires no additional nodes or links to be downloaded.

- For example, to synchronize a temperature, you can add a web thermometer to the page and use the node CONST.
- For the node CONST select the analog mode and enter the temperature that the sensor should not exceed.

- Add an INPUT. For the terminal select the sensor which measures the temperature, in our case a W&T #57715.

- To compare the value, we use the node GE This switches to True (1) as soon as the value on the input is equal to or greater than the comparison value. In our case CONST(22).

- Alternately you can connect the GE output with a Web-IO digital output, for example to activate a lamp or trigger an acoustic signal if the thermometer value is exceeded. You can also visualize the output of the Web-IO in the dashboard. Connect the nodes as shown in the illustration and save the flow.

- Value exceeded, output is True(1).

Creating a dashboard
- Click on Dashboard on the web interface of the logic.hub.
- Create a new dashboard by clicking on ADD DASHBOARD.

- Insert a Ticker label and an LED label. The Ticker label is assigned to the sensor terminal and the LED label to the digital output terminal, then you can also see in the dashboard when a limit value is exceeded.

- For the Ticker label you can for example also select whether the value should have a decimal place. In our case we do not require one.

- You can also add a Header label in order to give the dashboard a header. You can add this under "Full-width tile".

- After saving your dashboard is complete and limit value monitoring is automated.
