MQTT SparkplugB client

Devices Communication
1

Hello,
Does someone know how to configure MQTT SparkplugB client in FactoryStudio?
I didn’t find any example. And documentation is unsufficient.
I don’t know how to configere value name.
I don’t know if it is connected to broker or not. There is no Test function.

Thank you

Hi Tomas,

You can find the steps how to use the MQTTspB driver in the Driver Documentation that you can open using the engineering environment in Edit > Devices, select the MQTTspB driver in the list and click on the Help button.

However, we are describing below the same information you will find in the driver documentation:

  1. After selecting the MQTTspB protocol in the list, click in “Create new…” button;
    1.1 In the Protocol Options field, pick the Type of your application according to the Description:

    • Application Node: It is a MQTT client can subscribe but not publish to topics.
    • Scada IIoT Host: It is a primary MQTT client that can subscribe to topics and also publish commands (messages) to EoN Node nodes and devices.
    • EoN Node: It is a MQTT client that has as its main function to publish messages read from field equipment. It also can receive commands from Scada IIoT Host.
      1.2 Fill the remaining fields according to the documentation.

  2. In Edit > Devices > Nodes, create a new node assigned for the MQTTspB Channel. Here you will input the information required to connect to a Broker.

  3. In Edit > Devices > Points, the address field is filled according to the syntax: <Group_Id>/<Edge_Node_Id>/<Device_Id>/.

We recently did some improvements in this driver, so we recommend you to use FactoryStudio v9.1.14 to test this driver. You can find the link to download this version below.
fs-9.1.14.exe

One of the important modification in this version, now in Device > Points > Address field you can browse to an existing item in your Broker.

To check if the communication is ok with the Broker, in Runtime, you can look some diagnostic messages through the TraceWindow tool, with modules Devices and Debug enabled in Settings. Or you can open the Module Information tool, selecting the MQTTspB node in the TreeView.

Regarding the examples we are attaching the links here, but they will be available in the support help desk in the solution section soon. If you don’t have access, please email support@tatsoft.com with the request.

Below you can find a list of documents, videos and sample projects.

Also, following others examples, documentations and video about MQTT protocols.

Best Regards,

hi I’m testing factory studio demo with MQTT sparkplugB but browsing namespace option is not available in my version and factory studio doesn’t get the right value
how this issue can be solved knowing that i’m using fs9.1.8

Hi @mlotfyzidan,

When you’re talking about demo, are you saying that created a demo project?

In order to have communication between FactoryStudio and MQTT, you need to check if the Broker is running and ensure that there is data transmission.

In this topic, it is possible see that our recommendation is to use version FS-9.1.14 that has some improvements.

Is possible for you download and install the FS-9.1.14 and perform a test of communication again?

If this issue persist, please send us an email (support@tatsoft.com) with your project attached.

Below you can find a list of documents, videos and sample projects.

Hello,
I am attempting to setup a MQTTspB device. I have followed the MQTT SparkplugB Client Communication Driver documentation. I have setup a data model using templates as described in the documentation.
However when I try to enter the main element in the Devices → Points → TagName column it will not accept just the main element. The field turns red and has a red exclamation point next to the row. It says to enter a tag property.
I have tried to download and open the sample project, however that had it’s own problems that I posted about here: Project upgrade option not available

Also when building the template, is it necessary to follow the structure exactly as it is on the MQTT broker. The topic names on the MQTT broker contain spaces. An item in Frameworx can not contain spaces. For instance on the MQTT broker a topic may appear as “Pump 1 auto”. This item in a Frameworx template would need to be entered as “Pump_1_auto”. Are these differences reconciled automatically? Or does the structure on the broker and in Frameworx need to match exactly?

I am using version 9.2.26.
