  1. Hi Guys, I have a customer asking to have remote access to the web server of a UniStream PLC via internet (everything works perfectly in the local network). I am thinking to use EWON COSY vpn router in order to achieve a secure connection. Is there anyone who used this device before? What about connection reliability and response speed? Do you know of any other similar product which can be used for such an application? Thanks and Regards, Kikis
  2. Hi all, I have a web trend (not live trend) which works for 4 minutes and 30 seconds. The data sampler stores 5 feed values every 30 seconds. The time axis on the trend is 10 minutes. The trend starts on LHS and continues the lines every 30 seconds, but once it reaches 4 minutes 30 seconds (the 10th sample) it stops. Is there a limit to the amount of data shown on a web trend. I know the data sample is working, because I can see historic trends. Sam
  3. Seems like there should be an easy answer to this, but I don't see it. I'd like to flash text on a web page (i.e. flashing warning message). Using Frequency.Frequency 1 (s) to turn a visibility bit off & on doesn't work, presumably because the web page is not refreshing often enough. I know there are HTML tags to allow text to flash, but how to make UniLogic do that?
  4. Hi all! I have a problem with Protocol TCP/IP SCAN module. In my project I can connect this PLC (V350) with my computer through TCP/IP protocol. I use PROTOCOL TCP/IP SEND module for send information to PC and Scan module for receive it and that part work fine, with this, connection modules problems are discarded. My next step is connect the PLC with a server (same way). In this case I send a GET petition from PLC, when server receive this petition send another get petition to PLC with the valor of a variable stored in a data base, this petition must be read it by SCAN module and update some "flag" (MB direct contact) for activate a sensor (represented by a light bulb in HMI). At this point my problem is with SCAN module, petition is properly send it (I checked this with wireshark and checking the state of data base that is updated), but SCAN module is not reading petition properly because don't active the flag (don't change light bulb state). At present , both petitition seem correct, in wireshark send petition from PLC appear with HTTP protocol tag and server respond with status 200 OK HTTP and the correct message. Scan module is configured for read response from server too. What can be the problem? Thank you.
  5. Hi everyone! I'm developing a project with UniLogic v1.25.61 for the UniStream USP-104-B10. Everything's working well, but I made some changes in some buttons and fixed texts of the WebServer and when I download the project to the PLC and surf in the WebServer, the texts are not updated but everything else is refreshed. I've tried Full Download, but it's not working. I also try surfing in the WebServer from a new PC, but it's the same. Have anyone experience this before? It's quite strange because all the other functions of the WebServer are updated, but not the texts! Thanks in advance, Gonzalo
  6. Hi, I want to disable the “Remember Me” option when the user signs in (logs on) the web server on a Unistream USP-156-B10. Or shorten the password cookie life time to maybe 10 minutes. How can I do this? See attachment, Thanks, Gunnlaugur Asgeirsson
  7. Hi, is it possible to have the alarm summary on the web-server screen, using UniLogic?
  8. Dear All, is the first time that I use the web server...I tried to find what I need but, unfortunatelly, without success...I need to know when some one is conneced by web server, if is doing something by the web pages (push something...buttons or simply the screen) and how to load a web page by a BIT change....I try to explain...I created my DTI for the user/password ( I don't use the built-in function)...my web server main page will ask to insert these information...if the log will be ok a new page will appear and let the user do what she/he wants...if not action is done in some time automatically she/he will log out and the main page has to be loaded again...is it possible? thanks
  9. Hi, I'm trying to create a Web Server link to download a file stored on the SD card. I have tried copying the example shown in the help-file section "WE: Hyperlinks" but it returns an error "invalid URL address". How do you covert the SD card path into a valid URL so that it will link the anchor text to the SD card file. Kind Regards, Sam
  10. I've set up a Web Server page to display Timer values (Elapsed) but the box remains blank. Labelled in the attached image as 'Match Time' and 'Game Time' Any advice on what the issue might be would be appreciated.
  11. Hello! This is the first time I'm using web server applications by Unitronics... I have a product where I use a web server in communication with several embedded boards (yes, I need several boards instead of one, since each one performs independent functions and this number varies according to the demand of each client). But because of cost issues when the client makes a very large demand, I will need many boards to be managed by the web server, I thought about using the PLC, but I need to register several different IP addresses, since from each address I will send a package of data / commands. Is it possible to address multiple IP addresses and each receiving independent commands through the web server in a single PLC? What are my limitations? Thanks in advance!
  12. Hello, I am developing a php web application that is currently on an apache webserver on my local computer and i can access it via browser. The application is built in codeigniter and contains standard php, javascript, html, css files Can I fully transfer that application on the built-in Unistream web server and again access it via web browser? Thanks
  13. I have been asked a question about which operands are used by the Advanced Webserver. I always thought this was clear, but when I go searching for the answer, I can't find one. The question was posed in the old forum (go to final post) but was not answered: http://www.unitronic...858&whichpage=2 Specifically: The person who asked me the question also reports that values are being overwritten even though they are not listed as used in the basic webserver program. It looks like the advanced webserver uses some vectors, does any one have a comprehensive list?
  14. Hello, I'm using the advanced webserver based on a V350. If I put this program in my V350-B1 it works fine and I can see the different pages, but when I change my hardware configuration to a V570-57-T20B with a V200-18-E3XB print and put the software in the V570 my webserver doesn't work anymore. Could somebody tell me what I'm doing wrong? Thanks in advance, Edwin
