Post by respl on IFM EXOR Network variable Error ^{CODESYS Forge talk (Post)}
We are connected IFM CR711S to Exor EX710. We are exchanging data using network variables. Both devices are configured on same project so no need to use file source. When tested application it works fine. But after 3 months same application not working. We are able to send data from CR711 to EX710 but data from Ex710 to CR711s works only for one scan when we cold reset CR 711S. Can somebody help to find out error.

Post by simone on Preferred way of managing Ip-adress/es for linux (debian) host? ^{CODESYS Forge talk (Post)}
Hi pernockham, I think you should ask your device vendor. For some time I used one from an Italian company where they had made a library where you can manage the ip with a function (something like SetIPAddr...), it was based on connmann on linux. From my little experience is better to use the "default" way, so for me is to manage the config file on interfaces or use the ip addr utility

Post by ggis on Manage Gateways between different CODESYS IDE versions ^{CODESYS Forge talk (Post)}
Hi, I'd like to share the list of gateways between different versions (and sandboxes) of Codesys IDE. I refer to the list that is managed in Device > Communication Settings (as described in https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_edt_device_communication_settings.html ) Can I export/import that list? Or is there a file that I can copy from one installation to another one? Thank you GG

Hello, I’m using CODESYS V3.5 SP18. When I try to use SMC_ReadNCFile2 to read the file /PlcLogic/gcode.nc, the function block's bBusy output remains TRUE indefinitely. Can you help me understand what I might be doing wrong? Here is how I’m calling the function block. The value of strFileName is 'gcode.nc'. fbReadFile( bExecute := bExecute, sFileName := strFileName, bAbort := bCycleStop, fDefaultVel := RetainVariables.xSlowVelocity, fDefaultAccel := RetainVariables.xAcc, fDefaultDecel := RetainVariables.xDec, b3DMode := TRUE, bParenthesesAsComments := TRUE, fDefaultVelFF := RetainVariables.xFastVelocity, fDefaultAccelFF := RetainVariables.xAcc, fDefaultDecelFF := RetainVariables.xDec, ErrorID => gCNC.eErrorId, errorPos => gCNC.eErrorPos, ErrorProgramName => gCNC.eErrorProgName, bBusy => bReadFileBusy, sentences => sentencesss ); Thanks in advance for your help.

Post by arwie on Working on exporting/importing projects to PlainText. ^{CODESYS Forge talk (Post)}
To better track project changes in git I created a script that exports the project structure as text files. Textual POUs are stored as text, everything else as XML (with timestamps removed). The file structure is stored under path/to/your.project.txt Git merge will not work, but at least tracking changes is much easier. Script: https://github.com/arwie/controlOS_demo/blob/main/codesys/txtfy.py Example output: https://github.com/arwie/controlOS_demo/tree/main/codesys/controlOS_demo.project.txt

Post by pernockham on Persistence Manager: Config File not found? ^{CODESYS Forge talk (Post)}
I still cannot enable persistent manager for my project (and successfully login to a device). Project compiles with no errors but during download/login it fails with the fairly limited message "one or more errors occurred". The only clue I get from the system that this messages is displayed during "Generating code..: relocation pou". Any tips pointing me in a direction how to solve this very much appreciated!

Current. Could not cast: System.String in System.Char" I am using CODESYS V3.5 SP21 Patch 2. Is there a known solution or workaround for this issue? Notably, importing the same XML file through the CODESYS Engineering IDE's menu import works without error.

Post by spiessli on Softmotion axis to CANopen Maxon IDX drive ^{CODESYS Forge talk (Post)}
Hi, I want to use Maxon IDX drives for some simple robotic applications. I have used Maxon's Epos for generating a DCF file to import in Codesys (attached). Then I can add the IDX motors under a CANopen manager in the device tree. Unfortunately, I cannot add a "softmotion axis" to the IDX motors. Now I am wondering, why? Without being able to attach a softmotion axis to the device in the device tree, the use of the motor is greatly reduced... spiessli

Post by tk096 on SMC_Interpolator + SMC_controAxislbyPos ^{CODESYS Forge talk (Post)}
Hi, you can define a start position for your GCode. How the start position can be defined depends on the CompileMode: For File and SMC_CNC_REF: Set the start position input of SMC_NCInterpreter (https://content.helpme-codesys.com/en/libs/SM3_CNC/Current/SM_CNC_POUs/NC2/Interpreter/SMC_NCInterpreter.html) For SMC_OutQueue: * Right-click on the CNC object in the project tree * Select Properties * Select the tab 'CNC' * Set the start position Concerning your second question: If the new set position cannot be reached with the given velocity limit (AXIS_REF_SM3.fSWMaxVelocity), SMC_controlAxisByPos will report bStopIpo and close the 'gap' with the given gap dynamics (SMC_controlAxisByPos.fGap*).

Post by thomasrohnerch on Color Change for Symbols not working ^{CODESYS Forge talk (Post)}
I have some Symbols from the Visualization Toolbox on my Target Visu on the Computer. I tried many Symbols, mainly Arrows. I'm able to control the visibility with condition e.g. "GVL.actual_testvalues.speed <= 0" But I can't do "Toggle color" with boolean GVL.b_toggle_color. Neither "TRUE" nor "FALSE" does change anything. Is this a known issue? I'm using CODESYS V3.5 SP19 Patch 5 + (64-bit). See attached file with more Version-Info. I'm currently using Style 6, Gradient axial 2, 3.5.12.0. I had the same issue with Default 3.5.16.0.

Good morning, mecke96. Exactly the same thing happens to me, although I have not done the part of executing a .py file. It only reads the temperature and the counter, but the other values are zero as in your image "no readings". I have tested the MPU6050 device on an Arduino and it works. Could you tell me if you solved it?

Post by gseidel on CNC - system goes to X=0 Y=0 before CNC file execution starts, how to avoid that? ^{CODESYS Forge talk (Post)}
Hi peterned, the start position given in the CNC properties is only used if you use the compile mode OutQueue. With compile mode SMC_CNC_REF, you need to provide the start position in the IEC application. The function block SMC_NCInterpreter has an input piStartPosition. You can initialize it with the output of the forward kinematic transormation FB for your machine. In your case probably SMC_TRAFOF_Gantry2. Best regards, Georg

Post by wollvieh on License Activation Problems ^{CODESYS Forge talk (Post)}
on a raspberry pi delete the folder and its content before licensing. /var/opt/codesys/cmactlicense If you plug this SD card in another raspi ( which has another hw-serial number) you'll get a second empty softcontainer. This could lead to an unlicensed PFC (it could only handle one container) The solution is: To delete the /var/opt/codesys/cmactlicense directory and content of it and then aktivate the lizenz via WibuCmRau file and Lizenzmanager.

Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
All Sensors from the OneWire Master are assigned already to a seperate task with low prio (26) that runs with 1s cycle time. My EtherCat Task is running with Prio 1. It all works fine, until I adjust the CODESYScontrol.cfg or the CODESYScontrol_Usr.cfg files so that it supports a 2nd OneWire Master in the Codeys Runtime. If I change something in this config file and reboot my EtherCat Master stops working.

Post by manuknecht on Persistence Manager does not save alphabetically first value ^{CODESYS Forge talk (Post)}
After some more digging I realized that I get an error on the PLC Logger saying PersistenceChannel: 150 (invalid type in data: SimpleLibrary). I suppose the issue could be found in the ConfigData, which is automatically generated and which looks like this: 1 9##83 SimpleLibrary#GVL.aMoreZeros.[1]#0#64512#15#0 <[2]#0#64520#15#0 <[3]#0#64528#15#0 <[4]#0#64536#15#0 <#0#64544#15#0 <[6]#0#64552#15#0 <<lrVar#0#64560#15#0 <strVar#0#64428#16#80 <uiDummy#0#64370#11#0 Perhaps the fact that the variable is stored within a library confused the compiler? I tried changing the PersistenceChannel parameters to xCompressTags := FALSE which changed the entry in the data file from _xCompressTags BOOL:TRUE _xCompressTags BOOL:FALSE but the actual content of the data file and also the config data did not change.

As I wrote before on the title, I have difficulties to connect to see webvisu from localhost. The story: while waiting for the plc+hmi to arrive, I'm preparing the software, mainly the visual parts trough the control Win3 x64 (same version as the ide 3.5.20.10). The problem is that I can't see the webvisu with the installed webbrowser. I don't know if this is a problem, but I changed the port to 9001 (randomly "free") because 80, 8000, 8080, 8088, 3000 are all occupied by other projects (all on the Apache server). Is there something wrong with the config file? This is the url: localhost:9001/webvisu_app.htm and here the config file part "CmpWebServer". [CmpWebServer] ;The handling of startup/shutdown of the webserver: ;0->automatically start, shutdown only on shutdown of the runtime;1->automatically start, could be shutdown on demand ;2(default)->start/shutdown on demand;3->start on demand, shutdown only on shutdown of the runtime StartupType=0 ;The TCP port the webserver listens on WebServerPortNr=9001 LocalAddress=localhost ;LocalAdapterName=LAN-Connection LocalAdapterName=EthernetPCPLC ;LocalAdapterNameUnicode=L\00A\00N\00-\00C\00o\00n\00n\00e\00c\00t\00i\00o\00n\00 LocalAdapterNameUnicode=E\00t\00h\00e\00r\00n\00e\00t\00P\00C\00P\00L\00C\00 Thanks for all the help!
