Post by programmierer on Implementing UDP Communication ^{CODESYS Forge talk (Post)}
Hello everyone, I hope you can help me with my problem. I am new to programming and am currently working with a WAGO controller in our lab, which controls a heat pump. My goal is to send the electrical power of the heat pump (Pel_WP) via a UDP connection to a specific IP address. I am using Codesys version 2.3 and following the guide I found here: https://forge.codesys.com/forum/de/396/genmed-Konfiguration%20der%20UDP%20Kommunikation%20Cosesys%20S7.pdf. I have adapted the guide to suit my needs. The data sending works since I can force the reception value Pel_WP and the data is sent accordingly. However, I am having trouble with the receiving part. The reception value is not being correctly received, and the diSocket variable shows -1. The connection between the heat pump and the WAGO controller seems to be set up correctly, as the heat pump is listed under the communication parameters with the correct IP address. I have also attached images to provide a better view of the setup. I would greatly appreciate any support or suggestions for a solution. Thank you in advance!

Post by fredruel on ModbusServer became unreachable if reach maximum of 16 byClientConnections ^{CODESYS Forge talk (Post)}
Hello Fraziersedge, the solution of Codesys might be to update your codesys to the lastest version but it was not possible for us. In our Codesys V3.5 SP9 patch 8 I was able to fix this bug. I change my ModbusTCP slave component version or one of the sub component version (ex: SysSocket). Look at the picture in attachement that's the receipe that have work for us. When I got the bug my version of ModbusTCP slave was 3.5.5.0 with SysSocket at 3.5.6.0 and I change to ModbusTCP slave 3.5.14.0 with same version 3.5.14.0 of SysSocket event if I still use codesys V3.5 SP9 patch 8.

The following guide describes how you can adapt the user management for the first time in a project. It deals with the definition of a user and a group to which he belongs. Requirement: the project for which the user management is to be set up is opened. There is no adapted user configuration yet. Select Project Settings ‣ Users and Groups and then the Users tab. The user Owner is already created by default. Click on Add. ⇒ The dialog box Add User appears. Enter a login name, for example ‘Dev1’, and a password. Leave the option Activated activated. Click on OK. ⇒ On creating a group for the first time, CODESYS now requests you to authenticate yourself to perform this action. In this case, enter ‘Owner’ as the current user. Do not enter a password, just click on OK. The user Dev1 appears in the list and is automatically a member of the group 'Everyone'. Change to the tab Groups, in order to add the user to a new group. ⇒ The groups Everyone and Owner have already been created. Click on Add in order to open the dialog box Add Group. Specify at least one name for the new group, for example ‘Developers’. Activate the checkbox next to the entry User ‘Dev1’ in the field Members. Click on OK. ⇒ The group Developers now appears with has user member 'Dev1'. Switch to the Users tab. ⇒ The user Dev1 now appears as a member of the groups ‘Everyone’ and ‘Developers’.

Post by gunstr on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
The problem has been resolved. Two findings are described below for future reference. The new RPi hw delivered during August 2025 has a MAC address from a new vendor series that is not supported by old runtimes. 4.17.0.0 or above is required. 4.17.0.0 does not pick up the correct architecture during installation and aarch64 has to be manually configured either in the GUI under operations or in /etc/codesyscontrol/CODESYSControl_User.cfg under the [CmpRasPi] section.

Post by daanyouknow on Using a raspberry pi and NVLs to log variables outside of Codesys ^{CODESYS Forge talk (Post)}
Hi, My PLC/controller doesn't support OPC UA, so my current plan to create a ringbuffer/circular logger is to connect a raspberry pi to it, use the Network Variable List receiver and sender and raspberry pi codesys runtime to get the variables to the raspberry pi, after which I will use the pi which DOES support OPC UA to get the variables to a python program which logs the desired variables for a certain amount of time for me, would this work? I don't want to spend 50+ euros + licencing fees for a solution that might not work.

Post by trusty-squire on parker servo and position ^{CODESYS Forge talk (Post)}
@gepert, When you say "I do not turn off power", are you saying you don't power off the drive, or you don't turn of the MC_POWER function block? I read your statement as you don't kill actual electrical power. MC_POWER should stay enabled. @Gustavo, not related to problem at all, but when you say 1.6 Nm is only enough torque to unscrew a loose bottle cap, I think that's a bit low. A quick mental math I use is 1 Nm is almost the same force as 1kG applied to a 10cm wrench. So 1.6kG applied to a 10cm wrench is still not a huge force, but more than enough to be felt if trying to turn the shaft by hand.

Post by mondinmr on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
In reality, other vendors are already moving towards integration with VS Code. B&R, for example, is likely the only one that could truly challenge Codesys in the market: they’ve overhauled their once-archaic environment (previously lacking ST OOP) and are now catching up significantly with Automation Studio Code, offering modern programming capabilities and native support for tools like Git and GitHub Copilot. The other big names in the market, frankly, are still light years behind. For smaller projects, typically handled by “wire strippers” (with all due respect!), a classic environment might be just fine. But once you’re dealing with thousands or even millions of lines of code—possibly organized in an OOP paradigm, spanning large teams, integrating third-party libraries, requiring version control, and performing comprehensive tests—a lightweight, responsive editor supercharged with AI-based features becomes essential. The real strength of something like VS Code lies in its vast ecosystem of extensions and integrations: from advanced Git support to automated build/test pipelines, and even AI-assisted autocompletion that already makes software development much more agile and productive. I understand that a PLC project involves more than just ST code (task setup, fieldbus configuration, libraries, etc.). However, there’s no technical reason not to at least provide ST files in a pure text format, making version control and collaboration far easier. B&R has clearly adopted this approach; I hope Codesys will accelerate its own efforts to offer a native, text-based integration and modern development tooling. Once you go beyond a certain level of complexity—dozens of configurations, OOP hierarchies, and distributed teams—you really do need “engineer-level” software tools, not just solutions targeting “wire strippers.” For large-scale automation projects, a more open and flexible approach is the only way to avoid chronic frustration. Let me emphasize that I truly love Codesys and consider the work done so far to be brilliant—I’d be sorry to see it overshadowed by others moving faster in this direction.

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

Post by kevinrn on Signing Packages without exposing the password of the certificate ^{CODESYS Forge talk (Post)}
Indeed, I'm also seeking a solution for this issue. The main challenge we face is the requirement to use EV (Extended Validation) Certificates. Due to security considerations, it's not possible—nor is it ever recommended in such cases—to export the certificate with its private key.

In your soft plc folder, there is a file called targetvisuextern.cfg. Open this with a text editor to change the settings. Remove the semi-colons in front of the lines to enable your custom window settings. WindowType=0 means you will get a moveable window. Save the file and restart the soft PLC to enable these settings.

Post by dhumphries on Using Codesys example problems ^{CODESYS Forge talk (Post)}
You have to install any libraries needed by the sample program. Click the button with ... next to one of the errors (see attached image,) then choose download missing libraries. Codesys should automatically locate and install the missing libraries, it's not flawless though, I've had some issues getting libraries to install. The best advice I can give if it doesn't work is re-install Codesys.

Hi, I have an issue with a function which sends a message through API Rest. I'm using a function from httpCLient library. I have tested this function inside a program and it works fine. But when I want to use it inside a function (so I can call it simultaneously from 2 different points on the main program) it gives a stack overflow error. In detail it says: "C0297 Stack Overflow on Main Task. Stack sizes... Call hierarchy:" I have simplified as much as I can the function, but I'm hitting a wall with this. Anybody has an idea of what's wrong? Thanks!

Post by gatto on Undertanding Application Based Licenses ^{CODESYS Forge talk (Post)}
Hi, i think you are right. Did you press the key shopping cart? Codesys tells you the license. What I don't appreciate is that i need an additional license for communication. The system reports opc ua but this cheats you. This is communication that also concerns the tag symbols that codesys eth v3 exchanges with an operator panel. Attached is a screenshot of my case where you can see that communication opc ua is cheating you. 512 tags included in the program license are few. So, I had to buy 2 licenses. one for the program and one for communication. I don't like this policy.

Post by gatto on Backtick identifiers ^{CODESYS Forge talk (Post)}
Hello, I’m in Codesys 3.5.20.40 and I try to declare the variable ´var1´ but I get an error. here : https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_rules.html i read : Backtick identifiers By using backticks, characters can also be used in identifiers that are not normally permitted in identifiers, such as special characters. The acute accent character is used for backticks: ´ (Unicode: U+02CA) The use of backticks is recommended in order to be able to use the same identifiers in CODESYS as in other programming languages or documents, such as circuit diagrams. Any character may be used between two backticks, except line breaks and other backticks. Keywords are also allowed as identifiers between backticks. Examples: ´Variable+9´ ´INT´ The backticks are part of each identifier and therefore var1 and ´var1´ are two different identifiers. Example PROGRAM PLC_PRG VAR var1 : INT; ´var1´: INT; END_VAR var1 := var1 + 1; ´var1´ := 12; Are there any limitations or is something missing in my development environment?

Post by jonasz on Deploy LicenseServer for Linux SL ^{CODESYS Forge talk (Post)}
Good morning, I'm digging into this topic because I'm curious about resolving my problem in a test environment. In my previous message, I asked about the CODESYS Safe Timeprovider SL package (4.18.0.0), which I saw in the illustration. I noticed that it runs as a service. I am asking about this because from the perspective of an "ordinary" user, this service provides easier access to the settings of the time provider's operating parameters. The basic time provider configuration is outlined at https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_virtual_safe_time_provider.html. Why my questions? They stem from my specific case, which is experiencing timeout issues. I know that my environment is currently only a test environment. I'm assuming a real-world scenario in which I won't be able to achieve a better result with my configuration, and I will ultimately need to increase the time provider's cycle time. By running the time provider service, I can easily influence the time provider's operation and thus eliminate the problem. I know, I know, safety systems are not life-enhancing extras.

Post by gustavocsw on MQTT memory leak problem ^{CODESYS Forge talk (Post)}
Hello everyone, I'm using the IoT Library to implement the MQTT communication with my local broker server in order to publish and subscribe at specifics topics to share and consume information about my application. But, it seems that are occurring some memory leak problem in a "high" frequency (more than 10 Hz) subscribe process. I follow the same method as in IoT Lib exemples, and at first looks perfect but my PLC was rebooting frequently and when I check its memory usage that was increasing as fast as the subscribe massage was sent. I'm using a WEG PLC410 and a WEG PLC500, and this error occurred in both of them (including in CODESYS Control Win x64). The application sends to the system a message JSON with the float payload Ex. {"data" : 0.8500}, but this happens with a INT, or BOL as well. I use the follow code in my application to find the value: //FindFirstValueByKey VARs PROGRAM JSON_VELO VAR //------Setting the JSON Subscriber to Set the Relay Value jsonDataVelo : JSON.JSONData; jsonByteArrayReaderVelo : JSON.JSONByteArrayReader; xST1okVelo : BOOL; FindFirstValueByKeyVelo : JSON.FindFirstValueByKey; jsonElementVelo : JSON.JSONElement; xDoneReaderVelo : BOOL; xDoneFindVelo : BOOL; //STRING and WSTRING for Subscribe the massage sPayloadJsonVelo : STRING := 'opa'; psPayloadJsonVelo : POINTER TO BYTE := ADR(sPayloadJsonVelo); //wsPayloadJsonRelaySet : WSTRING := "opa"; wsPayloadJsonVelo : WSTRING := STRING_TO_WSTRING('opa'); pwsPayloadJsonVelo : POINTER TO WORD := ADR(wsPayloadJsonVelo); lrVelo : LREAL; xKeepAliveVelo : BOOL; xSetVelo : BOOL; RSSet : RS; LIMPAR : STRING; //Find the msg end sFindVelo : STRING := '}'; psFindVelo : POINTER TO STRING := ADR(sFindVelo); iLenVelo : INT; iSizeVelo : INT := 12; udiContMsg : UDINT; END_VAR // FindFirstValueByKey CODE // Relay Set configuration xSetVelo := MQTT_SUBSCRIBER.RSVelo.Q1; IF xSetVelo THEN xKeepAliveVelo := TRUE; END_IF IF xKeepAliveVelo THEN udiContMsg := udiContMsg + 1; iLenVelo := TO_INT(StrLenA(psPayloadJsonVelo)); iSizeVelo := iLenVelo - TO_INT(MQTT_SUBSCRIBER.udiPayloadSizeVelo); StrDeleteA(psPayloadJsonVelo,iSizeVelo,iLenVelo); wsPayloadJsonVelo := STRING_TO_WSTRING(sPayloadJsonVelo); pwsPayloadJsonVelo := ADR(wsPayloadJsonVelo); //MQTT.ConvertUTF8toUTF16(sourceStart:= ADR(sPayloadJsonVelo), targetStart:= ADR(wsPayloadJsonVelo), dwTargetBufferSize:= TAM, bStrictConversion:= 1); //Reset jsonByteArrayReader jsonByteArrayReaderVelo ( xExecute := TRUE, pwData := pwsPayloadJsonVelo, jsonData := jsonDataVelo, xDone => xDoneReaderVelo ); FindFirstValueByKeyVelo( xExecute := xDoneReaderVelo, wsKey := "data", diStartIndex:= 0, jsonData := jsonDataVelo, jsonElement => jsonElementVelo, xDone => xDoneFindVelo ); IF xDoneFindVelo THEN lrVelo := jsonElementVelo.value.lrValue; //Reset jsonByteArrayReader jsonByteArrayReaderVelo ( xExecute := FALSE, pwData := pwsPayloadJsonVelo, jsonData := jsonDataVelo, xDone => xDoneReaderVelo ); FindFirstValueByKeyVelo( xExecute := FALSE, wsKey := "data", diStartIndex:= 1, jsonData := jsonDataVelo, jsonElement => jsonElementVelo, xDone => xDoneFindVelo ); xKeepAliveVelo := FALSE; GVL.xSetVeloRead := TRUE; END_IF END_IF And this to subscribe at the topic: //SUBSCRIBE VAR: //----------------- Subscribe Velocity ----------------------- MQTTSubscribeVelo : MQTT.MQTTSubscribe;//Variable MQTTSubscriber block -X - function-X wsTopicSubscribeVelo : WSTRING(1024) := "CORE/odometry/GET/data/simp"; // Topic to publish a message sSubscribeMassageVelo : STRING; udiPayloadSizeVelo : UDINT; xSDoneVelo : BOOL; xSErrorVelo : BOOL; xReceiveVelo : BOOL; eSTypeVelo : MQTT.MQTT_ERROR; eSMQTTErrorVelo : MQTT.MQTT_ERROR; RSVelo : RS; udiCont : UDINT; //SUBSCRIBE CODE: MQTTSubscribeVelo( xEnable:= MQTT_CLIENT.xConnection_Broker AND NOT xSErrorVelo AND NOT JSON_VELO.xKeepAliveVelo, pbPayload:= JSON_VELO.psPayloadJsonVelo, udiMaxPayloadSize:= SIZEOF(JSON_VELO.sPayloadJsonVelo), udiPayloadSize => udiPayloadSizeVelo, mqttClient:= MQTT_CLIENT.ClientMQTT, wsTopicFilter:=wsTopicSubscribeVelo, xDone => xSDoneVelo, xError=> xSErrorVelo, xReceived => xReceiveVelo, eMQTTError=> eSMQTTErrorVelo ); RSVelo(SET := xReceiveVelo, RESET1 := JSON_VELO.xKeepAliveVelo);
