Ah Super. Danke!!
Hi, wie wurde das Thema denn gelöst? Ich habe gerade den Raspberry mit der letzten version (bullseye) frisch installiert und erhalte besagte Fehlermeldung: Please check if /dev/char_dev is available! ooops... this runtime was built for RASPBERRYPI Im Anhang sind die Logs und zusätzlich ein strace Log ohne dass ich hier verdächtige SYS Calls sehe. Ausserdem die Std-Ausgabe. Vielen Dank
Hi, has this ever been solved? I purchased a ModBus TCP license but also fail to install it with the same error. Note, I haven't licensed the RPI runtime yet. This is one is still running with the 2h timeout. Would this be a prerequisite for any other features to be licensed (which expire already after ~20min). Thank you!
Hi. thanks for your replies....This was a "layer 8 problem". Still not knowing how I got in and out of this mess I am now back on track... Just two last questions (taking this thread totally off-topic:-( ): 1) The icons for modbus do not turn green but are operational... any deeper meaning to this ? 2.) If this is related to the demo license (for raspberry), do I also need an additional license for ModBus ? The logs let me assume this: Demo mode for Modbus/TCP Master started. Thank you
Hi. Just a fresh reinstall of the latest RPI OS. The CodeSys runtime is 4.2.0.0 logs. It seems the device error is gone, yet I still can no longer get the modbus tcp conncetion to work. Even though the logs seem to indicate that the slave (192.168.100.106) is the root of the issue, I can assure that not a single byte is crossing the wire in neither direction as I am checking via tcpdump/wireshark using display filters for mbtcp. It all worked flawlessly until 2 days ago and now I am getting the error...
The error just popped up again... stuff was working fin till yesterday :-( Hardware : BCM2711 Revision : c03114 Serial : xxxxxxxxxxxx Model : Raspberry Pi 4 Model B Rev 1.4 root@rasp4:~# uname -a Linux rasp4 5.10.83-v7l+ #1499 SMP Tue Dec 7 14:08:09 GMT 2021 armv7l GNU/Linux Any ideas ? Thx
Hi. Is this confirmed to be a license issue ? I ran into precisely the same issue, see https://forge.codesys.com/forge/talk/Engineering/thread/8bdf13b8f6/?limit=25 Thank you!
Hi @i-campbell, I was able to replicate the unresolved references using Control Win V3 x64. See screen shot. Pls note that the application was not changed a single bit. It works fine for the Softmotion edition and errors out on the advised successor. Thank you!
