Cant Connect Lan v5.01.1

[freemchr]

Today all of a sudden I cannot connect to my profilux from one computer.

The PC is connected via LAN and using ProfiluxControl v5.0.1.1

Firmware version on the profilux is FW-Version 5.01b date: 05/08/2010

The error I get is Communications Error : Error Code 28.

Any ideas? From another computer plugged in can connect straight away.

Do you accidently enabled "search for SMS-Module" in PLC connection settings?

[freemchr]

Yes but the SMS module is connected.

[GHL Support]

Is the SMS module fully powered (Supply-LED and Power-LED is on)?

please try to connect without option "search for SMS-Module" to exclude if it has someone to do with the SMS-unit

I have removed the SMS module completely as there was a problem with it. It is disconnected and removed. I have tried reconnecting from this computer without the search for SMS Module ticked and I still have the same problem. Any ideas? A reinstall of the software did nothing. However from another computer can connect straight away.

Are there two network interfaces in the PC with the problems? Maybe a (wired) LAN and WLAN? This may be a problem.
Are you able to access with the problem PC the ProfiLux web interface and other PCs in your network?
