I'm trying to determine which Codesys Control license I need, the Control Standard S has all the features I think I'll need, but the code size is limited to 3mb, I created a simple program with only 1 line of ladder logic and a simple visualization with a button and an indicator. When I generate code I get some messages, one indicates that the total allocated memory size for code and data is 2.1mb. Is this metric the correct size of the code? I question the size because it exceeds the allowable code size for the Basic S and Basic M licenses and consumes 2/3 of the available memory for the Basic L or Standard S license. What tool can I use to estimate the size of code as it relates to the runtime license limit?

Hi all! I'm trying to learn PLC Programing. Today I was making a simple PLC program, as you can see. When I compile the program without the visualization, there are no errors. However, when I add the visualization and then compile it, I get this error. I donβt know how to solve the problem. I have tried the following solutions: rebooting the PC and updating the software. Error Code: C0138: No matching 'FB_Init' method found for instantiation of VisuClientObjectMgr Compile complete -- 1 errors, 0 warnings Build complete -- 1 errors, 0 warnings : No download possible Version: CODESYS V3.5 SP21 Patch 3

Hi erveyone, Rau here, first time asking on CODESYS Forge: When working with my servodrives, a special behaviour is required on dsp402 0x60B8 object, a control that is not supported by MC_TouchProbe. For this reason, I'd like to ask: Anyone knows if there is any way to bypass or change the softmotion axis writting into 0x60B8 object? My main problem is that MC_TouchProbe.TriggerInput.iTriggerNumber only allows to choose between TP 1 and TP 2 (not both at the same time). iTriggerNumber only allows values [0, 1, 2, 3], other values triggers an error in the FB, wether SMC_TP_COMM_ERROR for values [4, 5, 6, 7] and SMC_TRIGGER_OUT_OF_RANGE with any other value. Best regards, Guillem

I am using a WAGO PFC200 PLC as an etherCAT master and a Keyence IV3-G120 with DL-EC1A attached as an etherCAT slave. I am using CODESYS V3.5 SP21 Patch 3. I was able to set up mailbox communication and can see values changing accordingly, but I want to know how I can map these values and reference them in my program. I am able to map the process data objects in the 'EtherCAT I/O Mapping' tab, but there is no where to map the mailbox values in the 'CoE Online' tab. Is there a way I can reference one of these values in my code?

Hi, I found the same issue, and I fixed with this steps: 1st go to codesys .cfg file. sudo nano CODESYSControl.cfg Then insert this: [SysProcess] BasePriority=Realtime Command=AllowAll Now we need to grant codesys root rights on Linux. Step 1: Create or edit the systemd override configuration: sudo systemctl edit codesyscontrol In the editor that opens, insert: [Service] User=root Save and exit: Press Ctrl+O to save Press Ctrl+X to exit Step 2: Reload systemd and reboot To apply the override: sudo systemctl daemon-reexec sudo systemctl daemon-reload sudo reboot Step 3: Confirm CODESYS is running as root After reboot, open the terminal and run: ps aux | grep codesyscontrol You should see something like: root 1234 ... /opt/codesys/bin/codesyscontrol.bin ... If instead it shows admin or another user, the override was not applied correctly. Step 4: (Optional) Confirm from within CODESYS In your CODESYS project, insert this test code to run the Linux command whoami: Make sure the lib SysProcessImplementation, SysTypes, and CmpErrors is on the project. VAR sCommand : STRING := '/usr/bin/whoami'; sOutput : STRING(255); refCommand : REFERENCE TO STRING; refOutput : REFERENCE TO STRING; resultCmd : UDINT; END_VAR refCommand REF= sCommand; refOutput REF= sOutput; SysProcessExecuteCommand2( pszCommand := refCommand, pszStdOut := refOutput, udiStdOutLen := SIZEOF(sOutput), pResult := ADR(resultCmd) ); Notes & Warnings This method gives full system access to the CODESYS runtime β do not expose this system to the public network without protection. Do not use sudo in commands inside CODESYS when the runtime is already running as root. @tomas111, in case you want to read the temperatur, use this command: sCommand:STRING:='/usr/bin/vcgencmd measure_temp';

Hi CoDeSys support forum, hope that this is the correct place to ask this. Might be double as i am new to Codesys and dont know all terminology. I am trying to test Codesys with a virtual plc on a raspberry pi 5. Already figured that i need Tools -> Deploy Control SL, enter Communication parameters. Codesys says "Connected". Then tab "Deployment", there i select "CODESYS Control for Raspberri Pi SL" and "4.16.0.0 (all)". Click "Install" and the gui turns grey and unresponsive. The titlebar says "Untitled1.project - CODESYS (Not Responding)" as well. Restarting Codesys and checking shows no package was installed. How to deploy the runtime? Thank you in advance for your time. Edit: After some patience, an error showed up: "Error when sending ssh heartbeat: Session operation has timed out" "Error installing codesyscontrol" Any pointers to what remote command might have failed, or log of some sort, would be welcome. Software versions: Codesys version 3.5.21.10 Raspberry pi 5 (deployment machine): $ uname -a Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64 GNU/Linux $ lsb_release -a No LSB modules are available.
