Webinar - WebServer

This webinar covers the basics of implementing a Web Server with Unitronics controllers in VisiLogic.





Questions

Q: Can the Simple Web server display Trends or bar graphs?
A: No, the simple web server is only able to display operands types, MI, ML, SB. The enhanced web server can be used if a user can create a web page that has this functionality

Q: So the simple Web Server is basically text and numeric’s?
A: Yes, it is meant to be a quick and easy way to get access to information over the web browser

Q: Can you change the colors and text size on the simple web server?
A: You can use the alarm option to give color to a certain range. the colors are red, yellow and green. You can set the range where the colors will change

Q: Did I miss Where the main page be modified?
A: No, the main page is always the same information, which comes from the particular controller, OS number, controller… We create another, or a few more, pages with the information we want to display

Q: I now see that the manin page can be modified in the advanced web server. I assume can not be modified in the simple server?
A: That is correct. The simple is predefined. The advanced needs to be built.

Q: Any support for uname/pw access within the PLC web server?
A: This is not supported by the simple web server. We have built some function like this, using the MI entry and a compare sto simulate a PW. WE also use the a set of registers just for the web page, and if the PW is entered correctly, the really MIs will be sotred to the display MIs.

Q: Future support for https?
A: Probably not in the immediate future.
