I wanted to provide support personal way to access alarm history. So when user calls at 2 AM and says "machine stopped working" they can see what has happened and give advice for user, what to do. Sadly in current state you cant provide any indication of alarms on Web page. I know they can see errors on HMI screen. But If I provide support personal VNC access they are able to start engines over cell phones (in their bed) and I think it may be dangerous. Providing read-only VNC access is also problematic, because PLC is behind locked door (windowed) and for interactions they have to drive on t

Hi Everybody, I have created an application for an offset machine (a printer for plastic packaging like flower pots). We can move inker motors in position (x, y, z). It works like a charm and we are very happy with it. Now we want to be able to use an android tablet connected to the wifi of the machine to make adjustments. We do not want to use VNC, because this is just not an ideal way for a "permanent" setup. I have created an android app which connects to the webserver and shows the web page. This also works perfectly, but... The buttons on the screen only react on "release" an

Hi. Is it possible to convert an HMI screen to a web page? I want to have a web page that looks exactly like the HMI page, minus the controls. It would be nice if I didn't have to create everything from scratch.

Hello, On my UniStream (UniLogic 1.23.25, firmware 1.23.8) the web server in the various pages does not update some variables, not even if you update the browser with F5 (a once in ten it manages to update them), the strange thing is that if I go online with PC with unilogic, to monitor the ladder, the web server works perfectly. Or if I view a web page, from a browser, and move to that page from HMI, the browser also updates it. Someone can help me, or give advice about it I thank you right now. ldo

Hi - I have a Unilogic web server page going to port 5800 that shows the basic status of our system. I can see it internally no problem (on the LAN maybe you could say). For example the PLC Panel ethernet is set to 175.222.227.54 and I am on the same LAN where my IP4 address is 175.222.227.55 and so when I open Chrome and type 175.222.227.54:5800, hit enter, and I can see the basic status page. The issue is that I can't seem to view it externally (on the WAN?). We have Comcast Business internet and I think the problem has to do with how the IP's/ports are created and handled and with the f

Hi all, What could be the reason for this behavior: - web server don't refresh all of variables and elements; the real values appears, when I connect VNC client to the plc and go to the HMI screen, showing the corresponding variables (I think that going online with Unilogic 1.17.58, also helps). - FTP file transfer between two plc's in some moment freeze; going online and viewing the FTP server struct somehow fix the transfer. Could the reason be a large applications in the two plc's (70-80%), that I'm using, and the many communications in projects (CANbus, TCP , FTP)?

I am using a V130 series OPLC and I am working on an Advanced Web Server that will be mobile friendly. I like the simplicity of jquery and the power of ajax. I am currently only able to get the HTML to display from the web server. I am referencing the jquery files that are placed under Web on the SD card but they do not seem to load and the browser will hang for a bit before it loads the html without the jquery style sheets and structure. Any ideas? Comments? Also I am looking for examples of users updating operands with AJAX. <!DOCTYPE html> <html> <head> <meta charse -
Hi, I`ve installed V130 with simple web server application, at remote facility. I ve succeed to connect remote web server from control centers PC and it looks like it is working fine but ocationally link breaks.

Is there any other way to automate lost link recovery process? -
