Greetings, Happy Thanksgiving
I am new to RapidScada. Before you roll your eyes, I’m sorry to come off as a novice. Can someone please provide a step by step installation and setup of the MQTT plugin. If possible a video example like the setup video of Modbus on youtube.
I looked at the rapidscada’s doc section, github’s description and nothing shows where to place kpmqtt.dll, kpmqtt_config, job, jint.dll. I gather so far, ScadaComm directory. kpmqtt.dll —> KP? kpmqtt_config —> config? Where do the job & jint files go???
Can someone please hold my candyass hand? I would really appreciate a working example of setting up MQTT and a simple subscribe / publish to a broker; and printing it to dynamic text.
I’ve been using Mango Automation, Wonderware and would like to switch to RapidScada. Thanks alot.
Humbly yours
Hi!
We have posted a brief instruction in English https://github.com/RapidScada/scada-community/blob/master/Drivers/KpMqtt/README-EN.md recently. Maybe you will find it useful. In the manual we can get an example of configuring KpMQTT_Config.xmlYou need to place
1.kpmqtt.dll file in the folder C:\SCADA\ScadaComm\KP
2.kpmqtt_config file in the folder C:\SCADA\Projects\TestProject\Instances\Default\ScadaComm\Config
3.jint.dll file in the folder C:\SCADA\ScadaComm\KP
4.file job.js in the folder C:\SCADA\ScadaComm\KPThis driver was developed by our community, and at the moment the Rapid SCADA team has begun to finalize the driver.
Hi GreenFoxx,
I appreciate your reply. I moved the files to their appropriate directories; however, I’m still trying to figure out how set everything up in Rapdiscada.
The following is a good start:
https://github.com/RapidScada/scada-community/blob/master/Drivers/KpMqtt/README-EN.mdunfortunately, it still doesn’t help setup rapidscada. I can create a communication line… but the instructions say to link the mqtt configuration file. How is that done?
I would really appreciate a step by step setup of rapidscada with MQTT. It’s easy for the developer that designed it, but not the end user.
Thank you
I am having similar issues where should i place MQTTCore and Properties folders for mqtt installation?
Hi!
Brief instruction
1. Make sure that the library is available in the driver list.
Communicator-> Drivers.
Here you will see lists of available drivers. The KpMqtt.dll should be on the list.2. Add device type to the Dictionaries.
Configuration Database->Dictionaries->Devices Type
For example:
ID Name DLL Filename Description
(Last ID)* MQTT KpMqtt.dll MQTT driver3. Add Communication line.
Configuration Database->System->Communication line
For example:
Number Name Description
21 MQTT MQTT4. Add devices.
Configuration Database->System->Devices
For example
Number Name Device Type Communication line Description
42 MQTTtest MQTT MQTT MQTTtestOther fields are empty
5. Add input channel.
Configuration Database->System->Input channels
Before to this, you need to update data. Stand on the ‘input channel’, right-click and click on the ‘Refresh’ button
For example for [42] MQTTtest (here name devices)
Number Active Name Channel Type Object Device Signal
600 V mqttparam1 Calculate Real Enterprise MQTTtest 1
601 V Mqttparam2 Calculate Real Enterprise MQTTtest 2
602 V Mqttparam3 Calculate Real Enterprise MQTTtest 3Other fields are empty
* Number, Name must be the same like in configuration file6. Upload Configuration
7. Configure MQTT
Instances->Communicator->Communication Line
Stand on the ‘Communication Line’, right-click and click on the ‘Import’ button. Select communication line [21]MQTT (for example)
Line Parameters contains 3 tabs.1. Main Parameters
Here you can see the name and number communication line. In our example, number 21
2. Custom Parameters
Can be empty.
3. Request Parameters
Add following data:
In our example:
Number: 42 (number device)
Name: MQTTtest
Driver: KpMqtt.dll
Command line: KpMQTT_Config.xml8. Save and upload configuration
9. Start line (Stand on the [21]MQTTest, right-click and click on the ‘Start line’ button)
10. If everything is configured correctly, on the tab
Communication line->[21]MQTT->[42]MQTTtest you can see data. In our Example.Thanks a lot for your time GreenFoxx… I’ll play around with your guide tonight and reply back.
Thank you again
🍻

please help me
Hi!
Could you please check Configuration Database->Dictionaries->Device Type column DLL Filename
You need to write KpMqtt.dll (pay attention to the case of letters)Also could you please check Line Parameters ->Request Sequence text DLL.
You need to write KpMqtt.dll (pay attention to the case of letters)In your picture KpMQTT (MQTT in uppercase)
The message in the screenshot is not a error. You should check communication line log.
Where did you download KpMqtt.dll from?when i use “KpMqtt:v5.0.0
@2mik 2mik released this on 11 Sep · 10 commits to master since this release
KpMqtt: rename KpMqttConfig1”i have this error “Error getting device interface type from the library KpMqtt.dll: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework.
