Webvisualisation

CODESYS
1

I have a problem with the webvisualisation on one of my PFC200 (8202).

The https is working but not the http, eventhough all ports are open.

It’s programmed with e!Cockpit.

Anyone who had this problem?

When you say port Open, are you talking as Open in the firewall or as the Service is Running ?

You need this setting

Hi Tomas,

Yes, all ports are ok I think.

For some reason it’s working again but we don’t know why.

The service is running.

Since a few days the problem is back again. According to IT this is the problem.

In addition, the webvisu is displayed on a flowr TV.

If there is still a problem, let’s solve it. But I need a project so that I can check it on my PLC.

Hi, here’s the project.

I finally got around to the project. I apologize for such a delay. I see a lot of Modbus in the project. I had a similar problem when the PLC received requests from the Modbus Master. As soon as Modbus Master was disabled, it started working. I think you have the same problem.
Can you check?

Hi Thomas, the modbus communication is crucial since it’s providing the weather data to our Ride to Happines. I’m thinking about upgrading the project to Codesys 3.5 and see what happens. I will disable the modbus master communication to see what happens. Maybe the request to openweather can also be an issue?

Hello Anthony,

the behavior is resolved with FW24. See excerpt from the Release Notes. If you make the call with http under FW22, you should ensure that all web calls are made only with http. As soon as a mixed call is made (http and https), you will experience the behavior you described.
