UTL0001 Internal Error - Cannot build program. Yesterday, my program was working well. I was able to build it and to write and start on the connected PLC (AXC F 2152) but this morning, without having changed anything my project won’t build and I get an UTL0001 Internal Error without any other information. Now even if I open an older version of my project I get this error (even if this was a working version). I’m not using any external library. Can someone help me on this issue, I cannot find a solution to the Forum already and this is extremly inconvenient. Thanks in advance.
The PLCnext Engineer support team will need to get a project that shows this behaviour, along with the version of PLCnext Engineer that you are using. With your permission, I will email you instructions on how to send the project to us. I can use the email address you used to register on this forum. ~ Martin.
If there is an update on this, can you please update this post if the outcome could be interesting for other projects? We have the same problem, also in older backups the internal error is in the project now. We are currently researching with the dutch department of Phoenix Contact. If we find something I will also post an update.
