rkager Posted October 31, 2020 Report Share Posted October 31, 2020 Dear forum, we are evaluating a new projects ~100 Unistream US5-B5-T42 per year. We are focusing now an issue this PLCs will have all the same software and are connected to an edge device (linux embedded system with LTE modem) to our IoT Platform. We use ModbusTCP for data exchange, all fine. We have for other projects a roll out functioniality in out IoT platform and edge device software. So now the question: Is there a chance to update the user app of the PLC remotley without the UniLogic Software or usb drive? The problem is not the connection possibility itself but we have to update lets say 200 PLC next year so it would be not very convient to do that seperatley with an UniLogic download. And 200 updates via USB stick will always not work as there are no technicans on site. Thanks Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted November 1, 2020 MVP 2023 Report Share Posted November 1, 2020 This seems like a strange question. How would you imagine that it would be possible to update the PLC without the PLC programming software or a USB drive? And since it's possible to connect to the PLC remotely with the UniLogic software, why are you wanting to preclude that? Quote Link to comment Share on other sites More sharing options...
rkager Posted November 2, 2020 Author Report Share Posted November 2, 2020 Good morning. A FTP transfer to a present SD Card would be fussible and the PLC has to update then via the application. The main purpose is an automated update process can you imagine to update > 100 remote PLCs with UniLogic? And we are on a mobile projects so it might be possible to not have a stable internet connection. So it would be more secure do download the SW first to our edge device and start then the process. We do this with our own electronic in multiple ways (wifi, LTE-> send to microcontroller, store locally, ask user/or even no confirmation on some projects and update) Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted November 2, 2020 MVP 2023 Report Share Posted November 2, 2020 Got it. That sounds like a reasonable feature request. Quote Link to comment Share on other sites More sharing options...
rkager Posted November 2, 2020 Author Report Share Posted November 2, 2020 May I ask another question. As this could be our first unitronics project. I have basically only two ways to update (at unistream5): 1.) With an IP/USB connection and uniLogic download or 2.) a USB DOK and user has to open uniApps->User App Upgrade->Import Application? This sounds also a little bit bulky. Is there at least a way to start an User App Upgrade from Logic? So User App recognizes the DOK and starts the update itself? Thanks Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted November 2, 2020 MVP 2023 Report Share Posted November 2, 2020 @rkager We're not Unitronics employees here. These are both functional changes to UniStream so copy your posts and send them to support@unitronics.com. Let us know what they say.

This is a feature that exists with the Vision product and VisiLogic and one that I was likewise disappointed to see missing with UniStream. It may be on their roadmap however.

rkager Posted November 3, 2020 Author Report Share Posted November 3, 2020 Good morning. Thanks for your effort. I have already a ticket going on with the support team of unitronics but it seems to be a dead end. As software update is mandetory for this project we may have to rethink our strategy but there are not a lot of cost efficent -20°C HMI build in PLC in the market. (Vision HMI are starting at 0°C) But again thanks anyway. Quote Link to comment Share on other sites More sharing options...
rkager Posted November 3, 2020 Author Report Share Posted November 3, 2020 As an update: I have spoken with the head of tech support, they will add it the wish list. So as christmas is not that far your wishes will come true.. sometimes Quote Link to comment Share on other sites More sharing options...
