Linux WebServer to host visualization and connect to CX via ADS about ads HOT 1 CLOSED

Hi Petra,

first thing: I am in no way affiliated with Beckhoff. Nor have I used the AdsWebService component before. So what follows is just a solution that popped into my head reading your post.

As far as I know you will not be able to use the AdsWebService component on a linux system. The AdsWebService software package is an ISAPI-DLL deployed using Microsoft IIS. There is no chance you can use that exact component on a linux system. Since TAME 3 relies on the WebService-API you will not be able to use TAME for your visualization either.

So here is what you can do:
Use the library from this repository to create a websocket server which provides an API to read and write ADS variables from your CX system. An easy to use websocket library would be https://github.com/zaphoyd/websocketpp. Websockets could be replaced by AJAX as well... For some reason I feel more comfortable with the websocket protocol.

So your system could look like this:

Anyway. This looks like a bit of effort is required. Maybe someone from Beckhoff can show you an easier way.

Best of luck!
Michael

By the way, I'm not quite sure if this is the right place to post a question like this since the repository has nothing to do with the AdsWebService.
