PLCNext AXCF2152 not responding?

vikashchandola · March 4, 2020, 9:15am

I am using PLCNext AXCF2152. I was able to connect to device from PLCNext Engineer but recently is has stopped responding to PLCNext Engineer. ACF is not loading application either. I tried to restart PLC multiple times but there was no response. Resting plcnext service is giving following error. root@axcf2152:~# /etc/init.d/plcnext restart

Stopping service plcnext
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec … or kill -l [sigspec]

Hi Vikash, The clue is in the Output.log file:

Path '/opt/plcnext/projects/Default/Default.acf.config' does not exist.
This is a file that is needed for the successful start of the PLCnext runtime, and I am guessing that this file has been deleted at some point. The simple solution is to log in as root (e.g. using the su command) and delete this file from the upper directory, using this command:
rm /media/rfs/rw/upperdir/opt/plcnext/projects/Default/Default.acf.config
This will restore the default version of this file that was installed with the firmware. Hope this helps. ~ Martin.

Hi Martin, I tried above command. It failed with following error root@axcf2152:~# rm /media/rfs/rw/upperdir/opt/plcnext/projects/Default/Default.acf.config

I was able to recover device using following command recover-plcnext 1 PLCNext Engineer is now able to connect and ACF is also loading the application.
