Cara Bereck Levy Posted March 13, 2018 Report Share Posted March 13, 2018 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 Link to comment Share on other sites More sharing options...
Paul Rylatt Posted April 5, 2018 Report Share Posted April 5, 2018 Is there any intent to upgrade Visilogic based PLCs with the same capabilities? Link to comment Share on other sites More sharing options...
Cara Bereck Levy Posted April 25, 2018 Author Report Share Posted April 25, 2018 Hi Paul, The platform of those lines does not allow it. While we continue to support--as well as release new features--for these lines, these advanced features are supported by UniStream and the products that will follow it.

Ofir Posted May 2, 2018 Report Share Posted May 2, 2018 Hello Dan, Our MQTT client is basically generic. We cannot recommend about specific broker. We tried here brokers such as RabbitMQ. Link to comment Share on other sites More sharing options...

Santiago Fernández Posted August 30, 2018 Report Share Posted August 30, 2018 I've been investigating a little bit more about MQTT with Azure and I'd like to share my findings with you. The problem with the connection is the limit in the password field (128). Azure requires a SAS token for authentication that requires much more than 128 characters. The other option for authenticating to Azure IoT Hub (MQTT) is using a x.509 client certificate. That authentication option is neither supported by UniStream 5 MQTT implementation. My question is: would be possible to extend the password field limit? I'm assuming that implementing client certificate authentication is much more complex.

Rivka Posted September 2, 2018 Report Share Posted September 2, 2018 Hello, Thanks for posting! Starting from last version 1.24.56, the maximal length of the MQTT password had been extended to 255 characters. Is that enough for your Azure broker? Quote I'm assuming that implementing client certificate authentication is much more complex You're right, but it is right now in process and this new feature will be available in next UniLogic version (very soon) Hope it will help!

The point with the password is that Microsoft uses a SAS token for authenticating the client. This token exceeds the 128 characters. In my case my token is 139 characters long, so I think that this new limit of 255 character for the MQTT password is more than enough. Regarding the authentication using client certificates is also a real good news. It will add a good value for our projects. Thanks for the update Rivka!!

cmarcus Posted February 5, 2019 Report Share Posted February 5, 2019 Not sure this is the proper location for my question, but will there be a .NET driver or communications protocol for the UniStream as there is for the Vision? I've used literally dozens of Vision PLC's simply because I can tie together PLC operations and production control operations with several other peripheral devices (bar code scanners, RFID readers, measurement gauges, keyboard wedge devices, etc.) into a single PC based application, then integrate it into my customer's production systems or warehouse systems (SAP, SAGE, MFG Pro, and custom SQL databases). I've hesitated migrating to the Unistream models because I haven't seen a method as clean as the Vision .NET driver to read and write to specific memory locations in the PLC.

Thanks, -Chris Hi all, untill now I used the MODBUS protocol to connect the PLC with PC (C#) ...now I am trying for the first time the SQL and FTP (two different jobs) but a library/driver for the .NET like in the VISION (I took a fast look) could be nice. thanks Link to comment Share on other sites More sharing options...
GioSerrano Posted April 8, 2019 Report Share Posted April 8, 2019 Dear Cmarcus, Did you mention about implementations with SAP plattforms. Could you tell me about it. Do you have an example how do you made it ?? I need to connect to SAP system wiht Unistream 15,6" Appreciate your advice Giovanny Serrano Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted April 8, 2019 MVP 2023 Report Share Posted April 8, 2019 @cmarcus - Did you write a specific and separately running program in C# using the .NET driver to hook into an SAP system? Joe T. Link to comment Share on other sites More sharing options...

We would love to receive application stories involving MQTT I have a mqtt project with 40 identical machines all using the exact same application program. I am currently using Get and Set topic to add machine identifier for each plc. What would be a great feature is to have a tickbox to automatically add the unit id to the topic instead of doing Get and set in ladder. It would also save alot of work if the publish and subscribe lists could be exported and imported to a csv. Link to comment Share on other sites More sharing options...

kvlada Posted January 6, 2020 Report Share Posted January 6, 2020 In IoT projects, one of the most common problems I've encountered so far was Remote Access. Usually I have to connect a modem or a specialized WiFi/LAN gateway, and then configure DDNS, and setup some firewalling to be able to safely access PLC over the Internet. Wouldn't it be great for Unitronics to have a kind of own cloud service, which would allow a remote access to a PLC, regardless of their internet connection? Something similar to what Secomea is doing. You buy a subscription from Unitronics, and for example, $50/year you can access up to 20 different PLCs worldwide, through Unitronics Cloud, without the hassle of setting up VPNs, DDNS, and all that network stuff which usually fail the first time an engineer opens the cabinet and resets a router Link to comment Share on other sites More sharing options...
