ThomasStuermer posted a topic in Vision & Samba PLC + HMI Controllers & VisiLogic SoftwareHi to All, I've short question. Did anyone use the Unitronics Vision Controller for an IoT application with the MQTT protocol? I think the Unitronics OPLC will fit very well to the Internet of Things. Best Regards Thomas
I'm trying to configure a connection with Azure IoT Hub using the MQTT protocol with no luck. I need to configure the broker using the 8883 TCP/SSL with CA Certificate. I provide the correct certificate of the root CA but I always get the -1 status code (Cannot connect to broker. Check communication parameters) in the broker. I checked all the communication parameters and tested with a MQTT client (MQTT.fx) and I was able to connect correctly to the Azure IoT Hub. At this point my question is, is there any way of getting more information about which communication parameter is failing or getting more information for troubleshooting? Thanks in advance
People, over here at headquarters, we are curious. As you know, we are now embedding our PLCs with technologies that enable them to support IIoT, technologies such as MQTT that are need for Industry 4.0 applications. We want to know: Do your current projects require IIoT support? Are your clients expecting your solutions to support Industry 4.0? What features would you like to see in Unitronics controllers to help you with these projects? Do you feel ready for this stage of technology--do you feel that you have the knowledge, the resources that you need? Remember--your feedback helps us to set direction for R&D. We would love to receive application stories involving MQTT
This major release introduces MQTT, another piece of the Industry 4.0 puzzle. MQTT is a machine-to-machine connectivity protocol that runs over TCP/IP. MQTT joins the UniStream range of communication channels and protocols that supply the connectivity required by Industry 4.0 including SQL, built-in webserver that enables the controller to be accessed via any browser, and more. This release also supports new UniStream 5” models US5-Bx-R38 + US5-Bx-T42, offering new, built-in I/O configurations. Other important features in this release: HID Device support for devices such as scanners PostgreSQL support, in addition to SQL Server and MySQL UniApps localization for Korean & Italian, plus a new Korean virtual keyboard Read the version changes for more features at: https://unitronicsplc.com/software-unilogic-for-programmable-controllers/
