@Martin-Kudláček thanks for reply, but didn't help :(.

I think that you are right that PLC is unreachable for MERVIS. But I can attach PLC normally, like it is in manual.

Is there som way to restart PLC to deafult/factory settings, or something like that ?

Hello @Martin-Kudláček

I know, when I hit "Configure the Unipi module" error I mentioned up appears.
(Failed to connect to PLC, or confired device not available. Probably incorrect IP settings).

By the way.
TCP Parameters in properties panel is set to loopback and device port is 502 by default.
And mode switch to Commision mode seems working.

Hello Tomas

Thanks for response. As a first think, I instal EVOK, set the DirectSwitch on DI and used it for half a year. After that i wanted to switch to Mervis, so i reinstal OS on card. I use empty (default) project, in simple mode of IDE. I just want to change DirectSwitch configuration. And deploing Solution seems ok, Mervis said : Solution upload was succesfull.

Hello everybody

I have problem to get new configuration to M203. During uploading configuration by Mervis I am getting this error :

It's very odd because IP setting is correctly set. I can ping PLC and PLC see WAN.

What i've done :

1. I install OS (Raspberrian) and EVOK
2. Set DirectSwitch's on some DI (through web) and all went well
3. Erase OS by cleaning SD card
4. I install new OS - MervisOS
5. If i get configuration on Mervis, i see all DI with DirectSwitch=Disabled. But DS is still on ! I am not able to change it through Mervis.

I am pretty new at Mervis, so any help is appriciated :)

Thanks in advance

Lubos
