Post by arundara on OPC UA Server Stops after 5 consecutive disconnections of ethernet port ^{CODESYS Forge talk (Post)}
Hello Every one, During testing of OPC UA communication between UA Expert software and the CODESYS SoftPLC on a Linux environment, an observation was made. When the Ethernet cable was disconnected and reconnected with 2-minute intervals, on the 5th attempt, the OPC UA connection failed to establish in UA Expert software. At this juncture, restarting the CODESYS SoftPLC enabled the reestablishment of OPC UA communication. The same result was obtained when testing on a Raspberry Pi SoftPLC. What is the reason behind this phenomenon? and whether there are settings to stop this behavior? Please help. Thanks & Regards.

Post by kuegerls on SysProcessExecuteCommand2 and CANopen Device ^{CODESYS Forge talk (Post)}
Hello, CODESYS Control is running on my RevPi, and my system communicates over a CANbus with a master using the ConnectCan module (Slave - CANopen Device). The communication works perfectly fine so far. However, as soon as I call a Python script with "SysProcessExecuteCommand2" that creates a CSV file and executes without errors, the master does not adopt any changes to the Transmission Process Data Objects (TPDOs). I don't quite understand what one has to do with the other, and perhaps someone can help me with this. Here is my script call: SysProcess.SysProcessExecuteCommand2(pszCommand:='python /home/pi/test.py', pszStdOut:=sCMDOutput, udiStdOutLen:= SIZEOF(sCMDOutput), pResult := ADR(eResult)); Thank you in advance! Best regards, Stefan

Hello everyone, I have been trying to test the auto-login feature that is advertised on the Release Notes since Visu 4.8: *Version: 4.8.0.0 Besides some bug fixes and improvements this version contains the following new functionality: Alarmmanagement: Possibility to raise alarms programmatically Use real time clock of IEC context Automatic login for WebVisu using Chrome "Sign in automatically"* I am using a personalized login Visualization, the User Management works, however, when ticking the checkbox that keeps the credentials stored, after I reload the page I still see that the user and password details are not filled in. I tried with the default Login Visu (Blue one), and still see the same behavior - VisuUserManagement.VUM_LoginVisualization - I've tried with Chrome and Edge. Thanks for your help

Post by konstantin on CAM Motion Recover after STO ^{CODESYS Forge talk (Post)}
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

Post by timvh on library inside library ^{CODESYS Forge talk (Post)}
1) it should be possible to access the type SysTime in the project as A_Lib.SysTime. 2) you could add the SysTimeCore library to the library manager of your library (POU Pool). This might seem as a double library, but because of the placeholder resolution only one will be used. Then, in your library manager of your library, select the SysTimeCore library, right-click, select "Properties" and enable the option "Publish all IEC symbols ...." For more information about library development, you could follow our advanced training course in Ridderkerk. The next is scheduled for 24 and 25 June 2026 https://www.extendsmartcoding.nl/codesys-training/
