Unable to connect to the controller or activate the licence.
For last few days i have problem with connecting to the plc, no device found.
Sometimes help to connecting directly to the controller from laptop and i found the controller have diffrent IP address then i set. Very strange address like 169.254.26.84, i dont now why plc its changing the address sometimes. This is a big problem for me.
Also sometimes i wasnt able to connect to plc at all and i have to flash the OS on sd card to make work and now i cant activate the licence as well.
Today at night the controller just stop itself and i have to reboot in the morning to get my heating working.
Can you help with the problem?
did everything worked well after the call and email with our Support?
Yes, after reinstalling OS on industrial SD card everything its ok.
I think the problems became becouse of the wrong settings in Mervis DB and Proxy, also probobly i was saving the project in proxy profile, im not sure.
After reinstalling OS i didnt use Proxy or DB and it was ok, few days before i try to connect the controller to db and proxy and problem apear again, lucky i was able to disable them and after cold reboot everything its working fine. I think my settings its wrong, what its correct URL for DB and Proxy server, on Mervis KB site they are the same for diffrent version of Mervis. I got mervis 2.3.0 installed.
Also i have some questions:
