Post by gseidel on can not new a cam table in codesys V3.5 SP20 ^{CODESYS Forge talk (Post)}
Hi liai, is it possible, that SM3_Basic is missing in the library manager? (It should be inserted automatically when adding a Cam table, along with the other motion libs.) You can add it manually and see if that solves the compile errors. Best regards, Georg

Post by ulad on SPI Communication ^{CODESYS Forge talk (Post)}
Hello. I created a project that uses SPI. This project is working well. I can see with an oscilloscope that the SPI pins are actually changing. But when I resave this project in the IDE and open it later in the system, I see a constant error. What do I need to fix? What am I doing wrong? Thank you.

I have a video demonstrating the procedure to install the runtime on a linux device. https://youtu.be/rj0dOhgnGjs?si=OJoA-kgc1saxIweR This demonstration shows how to install the runtime on a X86 based controller, it should be the same for an ARM based device, but you'll need to install the add-in for Codesys control for Linux ARM SL (or the 64 bit add-in.)

Hi, Mine is the same, both using v3.5 SP17 patch 6, and v3.5 SP19 patch 5 when using anything newer than v4.8.0 the same issue as above occurs. Checked the 'Customize' window in case it was hidden/disabled in there but couldn't find it. Thanks for the help on this. Toby

To prevent ambiguous use of this enumeration value. Let's say another ENUM is available in your project or in another library which has an enumeration value AM_WRITE, then it is not clear which AM_WRITE you want to assign. By this qualified access to the SysFile.AM_WRITE, it is completely clear for the compiler.

Post by fcmtw on SDO generation ^{CODESYS Forge talk (Post)}
Hi, When I'm adding a CANOpen device in my WAGO CANOpen Manager, CODESYS automaticaly generates some SDO's that I can't directly disable. From what those SDO's are generated ? I'm not finding anything about it in the EDS files. Also, is there a way to disable the automaticaly generated SDO and execute the manualy created ones ? Regards, Florian

If you add any device to the CANOpen Manager it will send messages to verify the device is on the network. Do you have the Enable expert settings check box checked in the General tab? have you added any SDOs in the SDOs tab? I avoid using the CANOpen Manager and just use the CAN_Tx and CAN_Rx blocks from the library.

Post by thomas-moba on "sudo"-Befehle über die Funktion "SysProcessExecuteCommand2" ^{CODESYS Forge talk (Post)}
Guten Tag, ich muss via CoDeSys 3.5 SP 19 P5 "sudo"-Befehle über die Funktion "SysProcessExecuteCommand2" ausführen. Befehle ohne sudo sind kein Problem, aber sobald in einer sh oder einem Einzelbefehl sudo benutzt wird, funktioniert das nicht. In der CODESYSControl.cfg ist unter "SysProcess" Command=AllowAll eingetragen. Trotzdem geht es nicht. Weiß jemand woran das liegen könnte? Gruß, Thomas

please tell us the exact error message from diagnostic. U can view it at devicetree in the node-element diagnostic from modbus-configuration. u also can activate the function auto-reconnect in master and increase a little bit the timeout and the repetition to male thw communication a little bit more robust

We are using codesys 3.5.16.30 and we have a array with strings of length 5000. We are having issues subscribing to this variable from an OPCUA client. Is there any limit in the OPCUA Server in codesys for how long an array can be on the opcua server?

Dear, We have an issue with SoftMotion and it's licensing. We don't use SoftMotion in this project. But a SoftMotion license is required by it. The License metrics tell's us there is a -1 Axes. Is there a way to reset this? Delete this? There was a MotionControl device in the project, but we have deleted this. But it stayed at -1. Thanks for you help.

My experience is that opening pdf file is very dependent on which browser is used. I have tried a couple of them and only Mozilla Firefox has opened file correctly in same screen. All other browsers face some issues. Therefor I had to flip my pdf to txt which has not been nice solution.

You get fewer tools when you create a new POU and choose ladder diagram instead of ladder logic diagram. Create a new POU and select ladder logic diagram and you should find the additional tools you are looking for in the toolbox.
