Configuration Neuron M203 failed
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 :
- I install OS (Raspberrian) and EVOK
- Set DirectSwitch's on some DI (through web) and all went well
- Erase OS by cleaning SD card
- I install new OS - MervisOS
- 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
If you decide to go with Meris, do not mix other solution - the direct switch functionality can be configured in Mervis as well. You see it's disabled because Mervis does not read the actual configuration from the device. It expects that the IDE is the only tool to configure the HW so the latest configuration should be there.
However, the previous configuration of DirectSwitch should not have any affect to Mervis. Are you able to deploy the solution to the PLC? Could you share yoru solution with us?
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.
deploying of the solution doesn't affect the configuration of the IOs. You need to "Configure the Unipi Module": https://kb.unipi.technology/en:sw:01-mervis:unipi-configure-module-hidden
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.
if "Configure the Unipi Module" fails to connect to the PLC, that means the PLC is not reachable over ethernet. Try reattaching to the PLC.
Tip: this can happen when you switch Profiles. Reattaching usually helps.
@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 @LubomirMaron, you can always flash the SD card with the clean image. Then do the licensing and then upload the solution.
Thanks for everything, reflashing SD with new MervisOS helped.
