I'm trying to work with Codesys Control for Linux ARM64 SL 4.18.0.0 on a Toradex Verdin NXP iMX8MP. I have the runtime installed and operational as well as Codemeter lite 8.40.7141.503 (arm64). I'm running 3.5.20.60 and when "Scan Network" I see the Verdin popup. When I try to connect to it, the "mandatory use of the user management" popup shows...which makes sense. I click YES and enter user information and click OK. It immediately displays a "No device is responding to the scan request" popup. The IDE can see the Verdin in the scan...so this popup does not make sense to me. I thought maybe it was a read only issue but I've made all partitions and paths RW. Has anyone experienced this? Can anyone tell me where it is trying to write user data?

Some new test. Now I cannot connect from Automation server to my gateway in any way also from my office setup with my unit directly connected to my router by dhcp. I can use the IDE and the tool "Connect Edge Gateway" and successfully connect to my server/link to my Automation server account. However no PLC will respond from Automation server "Network scan". I guess the traffic should be initiated by the gateway towards automation server? Any tips on how I can diagnose my problem? Ports to be opened etc? Thing is that this has been working previously but not now (base system has been updated from debian 12 to debian 13, but I dont know at which point it has stopped working). Setup as before. A "Codesys Control for Linux SL" running on a debian 13 installation. Any help/tips appreciated! Per Update. Found the error. Had a wrong gateway-setting. Which meant the PLC could not reach internet. Checked by "ping google.com" from the PLC.

For whoever finds this old thread. Instead of System.exit(0), use system.exit(0) without capital 'S', this worked for me. I use these imports from future import print_function import sys import os

Hello, one of the projects I work on is about a racetrack collator with two independent belts on it - two different servo motors. Both motors share the same mechanical frame and there is a train on a belt that collects items from the input conveyor. The way the motion is performed is the following - there is a virutal master axis and both real axis are synchronised with different cam motion profiles. The problem is when an STO is triggered on any of the slave axis, the synchronization process starts from position 0 of the slaves. How can I force the slaves to retain their current position until the master passes their position? Then the slaves should catch up with the master according to the profile, the slaves should not start synchronization from 0 position. Best Regards Konstantin Kolev

Dear Mr. Kolev, can you please explain a little more: what happens at an STO? I assume the slave axes will be stopped and retain their current position? How, then, do you call MC_CamIn after the STO? Do you restart it with a new rising edge, but on the same master position as before the STO? Which StartMode are you using, is the cam slave absolute or relative, master absolute or relative? Are the slave axes modulo or finite axes? Best regards, Georg Seidel
