Hello,
sorry for the delay, I was really busy. Thank you all for your answers! I've managed to solve the problem with the mains power failure by adding the required line in krcextconfmsg.xml. Thank you SkyeFire .
Unfortunately I don't have SafeOp, so I think I don't have any choice but to shut down the supply. I've checked the behavior on another identical cell with the same robot+controller combo, but the error is identical.
Now I'm thinking about what can happen in the future (e.g. a new message that I've never encountered and that needs to be manually ack'd) and how to solve it remotely (if possible). In fact a lot of this machines will be installed around the world. Maybe RemoteSupportView? Or VirtualRemotePendant? Or maybe there are other ways that I don't know of? I know that I'm a little off-topic, but I didn't want to open a new thread just for this. Your guide is really appreciated.
Kind regards,
M
