Hi I have a strange problem with PLCnext Engineer. It’s not updating the program/changes in the controller: When i try to download a change, it’s like the old Program is stuck in the PLC. Even if i do a complete download, it do the same. I really don’t know how to update my program in the controller? PLEASE HELP QUICK!
Hello Emil,
I dont realy know what is going on there.
You can try restoring the PCWE folder at “/opt/plcnext” for a quick fix.
Maybe something went wrong there?
Are you using Custom C++ code or methods to change file permissions or anything similar?
kind regards,
Oliver
Hi, It’s only standard IEC code without any high level programs. No additional programs or librarys added to the project.

Hey All,
the issue seems to be caused by a download changes proccess in combination with an occuring Zero Division application error.
This behavior is now being investigated in detail.
It seems to be solveable by writing a non 0 value to the divisor and restarting the PLCnext runtime.
After that a Project Download seems to be successfull again.kind regards,
Oliver
