Post by francescoc on Logger in ms ^{CODESYS Forge talk (Post)}
Hi, I cannot find any documentation regarding the codesys configuration file. I modified this part to have log files saved to disk: [CmpLog] Logger.0.Name=LOGS/PlcLog Logger.0.Filter=0xFFFFFFFF Logger.0.Enable=1 Logger.0.MaxEntries=20000 Logger.0.MaxFileSize=5000 Logger.0.MaxFiles=10 Logger.0.Backend.0.ClassId=0x0000010B ;sends logger messages to SysOut Logger.0.Backend.1.ClassId=0x00000104 ;writes logger messages in a file Logger.0.Backend.2.ClassId=0x00000135 ;sends logger messages as UDP syslog Logger.0.Type=0x314;Set the timestamp to RTC ;Logger.1.Name=/tmp/CommLog ;Logger.1.Enable=1 I need to have milliseconds in the timestamp as well. What value should I use instead of 0x314? Is there any documentation regarding this file? Thank you

Hi, I am running Codesys Runtime by purchasing 'Codesys control for raspberry pi MC SL', I am trying to use the Variables from my GVL's. Few of the variables used as a Pushbutton form the Visualization. These 'BOOL' Variable getting unlatched automatically even though there is no write function in the Overall project. All of them are 'Read' functions, at the same time few other BOOL variable behaviors are seems to be fine. I have tried, clean all and download, serval time restarted the hardware. Happy to share any any information. Your input to resolve this issue would be highly appriciated. Version Details: codesyscontrol 4.8.0.0, armhf codesyscontrol based on SDK 3.5.19.0

I recognized that I have to start the two services "/etc/init.d/codemeter" and "/etc/init.d/codemeter-webadmin" in the docker container as well. If I do so, then the command "cmu -x" returns root@sensoredge-field-netfield-produktmanagment:/# cmu -x cmu - CodeMeter Universal Support Tool. Version 7.60c of 2023-Aug-09 (Build 5625) for Linux/ARMHF 64-Bit Copyright (C) 2007-2023 by WIBU-SYSTEMS AG. All rights reserved. So this time there is no indication any more that "Codemeter is not running". But still we are getting the error when using the license manager in CODESYS development system.

Hallo, nach der Portierung meiner Applikation von Codesys Version 3.5.18 auf 3.5.20 habe ich u.a. folgende Baustelle: Wenn in der Datei /etc/CODESYSControl_User.cfg die Einträge [SysProcess] Command=AllowAll und [CmpWebServerHandlerV3] AllowFileTransferServices=1 ergänzt werden, startet die Webvisu mit einer Login Abfrage. Die Webvisu soll aber (wie bisher auch) ohne Benutzeraktion starten.

Post by dhumphries on How to determine code size ^{CODESYS Forge talk (Post)}
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?

Post by sachem on Problem retain values Weidmuller UC20-WL2000 ^{CODESYS Forge talk (Post)}
Good afternoon. I am working with a weidmuller uc20-wl2000 controller, using a codesys license. We made a ladder code to control a process, and it works well, but we want some variables to remain stored even when the controller is turned off. We tried to use retain variables, but at the time of loading the program, when we went offline from the controller, the program was deleted, it did not remain in the controller, and in the same way if we turned off the controller. In addition to this, when we tried to program it again, the program would not stay loaded and began to present errors with the opc-ua communication. What could be causing this problem? How can we maintain the values of the variables without damaging the program or affecting the controller? thank you

Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge talk (Post)}
Good morning @eschwellinger, After some research I found out that the problem is the preinstalled CodeMeter on Raspberry Pi. As I mentioned the CodeMeter was installed on the Raspberry because I use a license from other vendor that needs the CodeMeter to be installed. The problem is that when I uninstall the CodeMeter from Raspberry I am able to detect the dongle from CODESYS and everything works as it should be but now the other product can not detect its own license. When I reinstall the CodeMeter I am back to the initial problem. Is there a way to overcome this conflict through CODESYS?

Post by fajean on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
4.11 appears to solve the problem. Thanks for your help. I had first installed the 64-bit version of RPiOS, but looking at various posts and the product's page on the store which only lists 32-bit compatibility, I downgraded to the 32-bit version. I did this before trying 4.11, and it did not solve the problem. Thus my working system is 32-bit, and I am wondering if I can go back to 64-bit or not. An 64-bit OS is not listed as compatible on the store's web page, but when installing there actually is a 64-bit version listed (automatically chosen when installing on 64-bit, but otherwise greyed out). Is 64-bit supported and the website is out-of-date, or is that some kind of work-in-progress?

This was reccommended in the following thread: https://forge.codesys.com/forge/talk/Deutsch/thread/7701332199/ But whenever i try to search for devices codesys just doesnt find anything and i cant close the "search devices" window. Has anyone got an idea what the problem might be? I already tried adding the devices connected to the pfc100 manually but the bus just doesn´t start. best regards Moritz

Post by alimans on Unrecoverable SoftMotion state after switch to PreOp ^{CODESYS Forge talk (Post)}
For anyone still experiencing this issue, here’s how I managed to solve it: Symptoms: 1. Sometimes, on the first start of CODESYS Runtime, the modules fail to run. 2. After disconnecting and reconnecting the communication cable, the drive does not start again. 3. MC_Reset cannot clear the fault. Solution (what worked for me): 1. Check the axis communication using the SMC_CheckAxisCommunication function block (FB). 2. If CheckAxisCommunication.eComState of the axis is equal to or higher than SMC_CommunicationState.SMC_COMSTATE_BASE_COM_INITIALIZATION, then 3. Use the SMC3_ReinitDrive function block to reset the drive — and it works. For more information, refer to the official CODESYS documentation: 👉 https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/DriveInterface/AXIS_REF/SMC3_ReinitDrive.html

Post by aria13 on Has anyone fed ESP32 sensor data into CODESYS (via MQTT/Modbus)? ^{CODESYS Forge talk (Post)}
Has anyone tried sending live sensor data from an ESP32 into a CODESYS runtime (for example via MQTT gateway or a Modbus bridge) to trigger PLC logic? I was reading an ESP32 → MQTT tutorial (https://www.theengineeringprojects.com/2021/11/esp32-mqtt.html) that shows how easy it is to publish sensor data from an ESP32, and I’m wondering how practical that is when tying the stream into industrial control software like CODESYS. I’ve also seen Arduino forum threads where people relay sensor streams to MQTT brokers and Raspberry Pi projects that bridge MQTT→Modbus, so I’m mainly curious about real-world issues: reliability, message latency, and simple patterns you’d recommend for safe PLC integration. Any tips, examples, or gotchas from folks who’ve done this?

Post by miltos on licensing question ^{CODESYS Forge talk (Post)}
Greetings to all, I'm working on a webvisu project on control win V3 x64 runtime, and have purchased 3 licenses for my application. -Codesys Control Standard M -Codesys Visualization L -Codesys Communication M I have them installed on a Codesys usb dongle When I try to download the program, a login error window appears with the message "No valid license found for the webvisualization". The control win v3 communicates with 3 plc, and have enabled communication over codesys V3 communication by adding one datasource for every plc in the datamanager. If I remove the data manager from the project, the rest of the visualisation can be downloaded normally. Do I need to purchase another License and which one? Please find attached the software metrics and the error screen.

Post by jonasz on Deploy LicenseServer for Linux SL ^{CODESYS Forge talk (Post)}
The machine I'm currently using (Celeron J1900) already has the Kernel RT patch. I checked the performance according to the documentation. After running CyclicTest for 4 cores, the value for each core is around 6-7. I went through the entire process according to the documentation (I envy the TaskMonitor results in the documentation). The documentation states: "CODESYS Virtual Safe Time Provider The CODESYS Virtual Safe Time Provider is a standard interface that the user can use to transfer a second and external time base to the CODESYS Virtual Safe Control. The implementation is done as a client, which must run on another system with an independent time base." How do I implement this? I've been struggling for two weeks now - I'm too old to give up.

Post by msirotkin on EtherCAT status errors ^{CODESYS Forge talk (Post)}
Hello, I'm trying to understand the reason for the many errors on the EtherCAT master status page. If we set the cycletime to 1ms we see a lot of rxerrors and lostframes, but the send and recive times are quite good (see attachement). And the status of the EtherCAT bus is good (no other errors, all is green, slave has no errors) But when we set 2ms cycletime the lostframe errors are gone, but periodically increses rxerror counter (see attachement). The questions is, what do these errors actually mean and what we can do to get gid of them? Linux RT, imx8, Codesys runtime for ARM 3.5.21.10, Ethercat 4.10 Thanks

Post by pernockham on Unable to deploy "Control for Linux SL 4.18.0.0" ^{CODESYS Forge talk (Post)}
The option to update "Control for Linux SL" is not shown in the "deploy control SL tool", I can see and update the gateway but not the control (3.5.21 SP4). Has the way to update control SL changed? In the process of fault finding I removed the control SL entirely from my target, then I had to revert to version 3.5.21.0 SP 1 to re-install "Control SL 4.17.0.0". So I thought it was just a matter of using SP1 to update also to 4.18.0.0, but after installing the files for 4.18.0.0 in the SP1-version, the behavior was identical to SP4, ie no Control for Linux SL shown in the deploy tool.. See screenshots.

With a machine I'm working with i get a communication error when I'm updating some softstop limits. As soon as I update the code the drives do not want to operate. Using the MC_readStatus I'm receiving errors as soon as i want to start a movement. Using MC_ReadAxisError i see that i receive error 131, no response. With a SMC3_ETC_ReadParameter_CoE i do not recieve any driver errors. Does anyone know how i can figure out what the error is and how to solve it. When i go back to the old software no errors occur. Im working with a legacy machine running a Beijer PLC with some Mitsubishi drives. running on Codesys 3.5 SP10. the runtime version is probably 3.5.3. The drives are all Ethercat Drives (CoE). All using the SM3_drive_ETC libary and the SM3_basic library.

Post by sheberle on No Bootproject possible ^{CODESYS Forge talk (Post)}
Hello Alex, the message is generated by the CODESYS code generator based on the DevDesc settings of the memory areas available for the target. The problem arises when after too many online changes the area is full. Therefore no more boot project can be generated. Short-term remedy as described in the dialog: Clean and fresh download. This way the initial memory size will be "used" again After how many online changes did this error occur? There is no set limit on the number of online changes, but making too many changes could be a risk. br Simon

Post by gatto on Two licenses have to be installed forgot to enable one license ^{CODESYS Forge talk (Post)}
Sorry, I've never used Raspy. Maybe someone else can help. From personal experience, I've had license activation issues, but it was caused by my company firewall, which was blocking traffic from the Codesys license server. So I found that the license was listed as activated on the server (and therefore used and no longer activable), but it wasn't present in the PLC. I solved the problem by using an unblocked internet connection when I needed to activate the purchased license ticket. Since then, the activation process has always worked, and I've never lost any licenses.

Post by kporter on Codesys EtherCAT Driver (CmpEt1000MPD) can't set MAC address ^{CODESYS Forge talk (Post)}
EtherCAT is a point-to-point protocol so it doesn't need a unique MAC address. It would be very useful to set the MAC address to 020000000000, the standard address for this kind of application. (The important bit is the 02 at the start of the address, which means locally-administered MAC.) The stock Windows driver can do this for my i210 card. But the CODESYS CmpEt1000MPD driver cannot. The image shows the setting with the Windows driver. If I set all my customers' cards to this address, then I don't need to deal with this when deploying my application. A simple PowerShell script can be used to set the MAC address once when the NIC is installed and the driver is changed.

Post by egr99 on Modbus TCP Server connection is ESTABLISHED but all holding registers are value 0? ^{CODESYS Forge talk (Post)}
You're absolutely right. Sorry for that. In the meantime I wrote a Function block to handle the reads and writes to the different attached RTU-devices. It processes the parameter like (str_Modbus:=(usiSlave:=1, uiFC:=5, uiLEN:=1, uiOFFSET:=0, uiInterval:=500)) and the corresponding output, waits for the response and processes next request in a 5-state procedure. It's working for 2 gateways (stable without errors, although error recovery is included). But nevertheless it should be possible with the Channel definitions of Codesys. Much easier to maintain :)

Post by trusty-squire on SysProcessCreate2 on Linux runtime ^{CODESYS Forge talk (Post)}
Hi, I'm trying to launch a continuously running python script from Codesys and monitor the script status inside the Codesys runtime (running on a Linux enviroment). For now I'm testing with the below to emulate a continuously running Python script: #test.py i = 0 while True: i += 1 I'm able to successfully run the script using SysProcessExecuteCommand2 (I can see the Python process running in the task manager). However, this "freezes" the Codesys execution of the task - it sits on that command and will not continue until the Python script ends. I've proven this works by using the task monitor to kill the process, then Codesys continues on happily through the task. What I want to do is use SysProcessCreate2 to set up the Python script as a background task and monitor the process using SysProcessGetState. This always results in the error "ERR_OPERATION_DENIED". I know that I'm able to execute commands (as above), so my config should be correct. Is SysProcessCreate2 functional on a Linux environment? Is there something in the config file I'm missing? Here's my "working" code that uses SysProcessExecuteCommand2: VAR bTest : BOOL; sCommand : STRING := '/usr/bin/python3 /var/opt/codesys/PlcLogic/Application/test.py'; refCommand : REFERENCE TO STRING REF= sCommand; sOutput : STRING; refOutput : REFERENCE TO STRING REF= sOutput; result : RTS_IEC_RESULT; END_VAR IF bTest THEN SysProcessExecuteCommand2( pszCommand:= refCommand, pszStdOut:= refOutput, udiStdOutLen:= SIZEOF(sOutput), pResult:= ADR(result) ); bTest:= FALSE; END_IF And here's the code that always results in the ERR_OPERATION_DENIED error: VAR bTest : BOOL; sApp : STRING := '/usr/bin/python3'; sCommand : STRING := '/var/opt/codesys/PlcLogic/Application/test.py'; refApp : REFERENCE TO STRING REF= sApp; refCommand : REFERENCE TO STRING REF= sCommand; hResult : SysProcess.RTS_IEC_RESULT; hHandle : SysProcess.RTS_IEC_HANDLE; END_VAR IF bTest THEN hHandle := SysProcessCreate2( pszApplication:= refApp, pszCommandLine:= refCommand, ulFlags:=SYSPROCESS_CREATEFLAG_HIDDEN, pResult:= ADR(hResult) ); bTest:= FALSE; END_IF Here's the relevant section from the config file at /etc/codesyscontrol/CODESYSControl.cfg: [SysProcess] Command=AllowAll Appreciate any support or ideas.
