Post by tcarlbom on Read tag values using external program ^{CODESYS Forge talk (Post)}
This is my first time posting in this forum and I am new to codesys. I am a fullstack developer and I am trying to figure out how the following. What would be the best approach to create a own/custom tag browser? Either directly in codesys ide or using a separate custom program (perhaps a winforms application). 1.a. Shall I parse the .project xml file to get a list of all tags in the project? 1b. Shall I use python scripting in codesys ide to get a list of tags? Once one have selected some tags. These tags shall be exposed to a python program which will be acting as a edge computer. It’s fine to be able to import a file. 2a. I found a library called codesys plchandler which (as I understand) acts a rest api server. Is this correct? If so, can I query the api from a custom python script, ie can query what tags exist in project and or read tag values? My research so far. From earlier projects I know that using opc ua would be perfect for this but from my opinion it’s bloating the plc since it’s resource intensive. So opc ua is not an option. Codesys automation server is neat. But I don’t want to rely on some cloud services and subscription based pricing. There seem to be several interesting codesys libraries like mqtt, tcp server and NVL sender which would help me expose plc tags. But all have a common problem. One have to manually write what tags which will be used in these function blocks. I want a similar experience like “selecting” tags in the opc ua or the codesys tracing, ie a tag browser.

Post by yannickasselin on MQTT QoS 1 & 2 ^{CODESYS Forge talk (Post)}
Hello, After some more tests, here is what I found out. It seems we have to increase the uiKeepAlive and tPingInterval parameters. If I increase the uiKeepAlive value to 60s and the tPingInterval to 30s, then if I disconnect the ethernet cable from Codesys and publish some messages to which Codesys subscribes to and then reconnect within 30s, I will get the messages. If I don't reconnect the cable within 30s (ping interval), the client goes in error with "ACKNOWLEDGE_TIMEOUT". When this happens, it will not automatically reconnect after reconnecting the cable. I have to disable and re-enable the client but I will not get the published messages. I need to do more tests because there are a lot of weird things happening when playing with the ping interval and the keep alive. It is not clear to me what does what. I even ended up not receiving messages anymore, even if I disabled and re-enabled the mqtt client. The client did not give any error. The only way I was able to get messages again was by modifying my client ID. After that, if I try to re-use one of the old client IDs, nothing works (publish, subscribe) and I get a TCP_INIT_ERROR and sometimes a TCP_READ_ERROR. I need more explanation/documentation about these weird behaviors. Maybe it is the way I use it, maybe it is related to the broker (I am using Mosquitto with default parameters). When using a Node-Red client, everything works perfectly. I am trying to achieve the same behavior with Codesys but it seems impossible so far.

Post by serwis on Dynamic target position tracking ^{CODESYS Forge talk (Post)}
Hello, I am trying to control a servo drive and dynamically set its position. I control the drive via EtherCAT with a cycle time of 500us. I use the MC_MoveAbsolute block for this. The problem is that when using a PID controller, I generate the positions I want the drive to move to on an ongoing basis, and I would like the position to be set immediately. The MC_MoveAbsolute block must receive a rising edge to execute, and I would like the movement to be performed without waiting for this edge. I have created a function that generates a rising edge every 1 ms, but I am unable to change this time to 500 µs because the TON function does not support times shorter than 1 ms. Below is the code to call the rising edge: IF Exe = TRUE THEN delay1(IN:=TRUE, PT:=T#1MS); IF delay1.Q = TRUE THEN Exe := FALSE; delay1(IN:=FALSE); END_IF END_IF IF Exe = FALSE THEN delay(IN:=TRUE, PT:=T#1MS); IF delay.Q = TRUE THEN Exe := TRUE; delay(IN:=FALSE); END_IF END_IF END_IF Here is the code for calling the MC_MoveAbsolute function: MoveDegree( Axis:= Tilt, Execute:= Exe, Position:= position_target - (base_angle_real * feedforward_turn), Velocity:= vel, Acceleration:= acc, Deceleration:= dec, Jerk:= jerk, Direction:= MC_DIRECTION.shortest, BufferMode:= MC_BUFFER_MODE.Aborting, Done=> , Busy=> , Active=> , CommandAborted=> , Error=> , ErrorID=> ); I realize that there are probably better methods for performing this type of task. How can I implement motion with a dynamically changing setpoint? THANKS

Post by e13740e on Сalling the context menu from the keyboard ^{CODESYS Forge talk (Post)}
Hello. I have a question for you, perhaps you have an answer to it. Regarding calling the Context menu from the keyboard in Devices, specifically calling the context menu window from the keyboard via an assigned combination. Goal: to have the ability to navigationally add internal Objects (Methods, Properties) to Function Blocks from the keyboard without using the mouse. The Codesys environment interface does not allow Windows access to this via Shift+F10. Externally (outside the Codesys environment), the hotkey call for the context menu (Shift+F10) from the keyboard works in various environments, but at the same time, in Codesys it does not (it doesn't work). I have already tried various options on my own to achieve this (but unsuccessfully): Tools\Customize\Keyboard\Objects (the set combination does not give the desired result) Tools\Customize\Keyboard\Objects... (the set combination is extremely useful as it provides access to adding objects directly to Devices but does not provide the ability to add an internal object (Method/Property) to a Function Block). Thank you in advance for your help!!! P.S. I have already started trying to implement a script-based solution to call the context menu via AutoHotkey - by relocating the mouse cursor to the area of the navigational selection with a subsequent call of the context menu on it and relocating the mouse cursor back to its initial position. And in order not to "reinvent the wheel," I am writing this request to you!!!

Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi all, I want to know if someone has an idea of how I can write on value change in Modbus Codesys. I have a Wago PLC and I was used to work with E-cockpit which it was quite easy to do that without the necessity to trigger any value when there was a change in the variable ( I will put how easy is ). how you can see just changing the trigger in "On value Change" will do that channel writing automatically when It detects a change in those arrays. On the other hand, in Codesys if I enable the rising edge in Codesys It ask me to put a bool variable and if triggers is going to write that value. That is making me that I have to create a function or a logic to detect the change, the problem I have is that doing that is very tedious. I first approach I got it was to create a Function who returns a bool when the value change, but I tried to keep the old value but what is happening is that in Functions all the data is erased every cycle so I can not keep any Old value. so in the Main program the trigger is going to be TRUE all the time due, the old value is cero every cycle. The second approach I got it was using a function Block (POU_1) and it works but I dont want to instance that function for every Channel or value that I want to check if the value change, Basically if I have 200 values to write trhough modbus I have to create 200 instances of that function which I think it is not practicall at all. It should be a better way to implement this as e-Cockpit from Wago Does. However, I haven't been able to know how.

For what ever reason the communications seems to end and lock up for about 20 seconds. During this time even if I was logged into the PLC it would kick me off and I’d have to re type the password to enter. Most of the devices can handle this however the RTU flags up a communications failure at the SCADA and is raising alarms every 2 hours and 4 mins. We’ve had multiple people go through the code to check for anything obvious. Does anyone have any ideas?

Since version 19 they changed how file access is handle. There are two solutions: 1. You change where the file is stored (need to go to: /PlcLogic/) 2. You can, if you don´t want to store at PlcLogic, add the following line in the CODESYSControl.cfg under [SysFile]: ForceIecFilePath=0 The CodesysControl.cfg is at C:\ProgramData\CODESYS\CODESYSControlWinV3x64\xxPROJECT_NUMBERxx\ Here the email they sent me: "with the 3.5.19 Version we changed how files are handled. See following issue: CDS-81506 - CODESYS Control SysFile system file access vulnerability. There are two solutions: 1. You change where the file is stored (need to go to: /PlcLogic/) 2.

Post by alexgooi on Codesys KNX implementation ^{CODESYS Forge talk (Post)}
Dear forum, We are currently doing some research on the Codesys KNX implementation (https://store.codesys.com/en/codesys-knx-sl.html). We almost have it working but we are missing the last part. The setup: We have a Codesys virtual control container running on docker (4.17.0.0), the I/O is running over an Ethernet IP coupler (Weidmüller), and this is running fine. As far as I’m concerned this tells me that the ethernet device is working properly (the container has access to the outside world, including multicast). Underneath this ethernet adapter the KNX module is added (see picture). In the KNX device (Codesys) 2 input variables are added (see picture), and these are exported to ETS (ETS 5). In ETS A Codesys KNX device has been imported and the Codesys export was imported, afterwards the group addresses are attached to the variables (see picture). Afterwards this configuration is downloaded to the Codesys controller (Container) via ETS. ETS asks for the pressing of the programming button, when the virtual programming button is pressed the download starts and finishes without any errors. This tells me that ETS is communicating with the Codesys controller, and that the download process is ok (so far so good). Now the part where we are struggling with, somehow we need to convert the KNX TP to KNX IP. For this we have the following interface: Zenio KIPI SC (https://www.zennio.com/product/kipi-sc/) this is a KNX TP to IP interface. We have the following setup for this device (see picture) (an IP in the same subnet is used). We tried multiple combinations of IP addresses but the TP devices are simply not communicating to the Codesys container. Does anyone has any advice on what to try next. To make the question more explicit how can we link the TP bus to the Codesys device? Kind Regards Alex

Additional Information The axis status page reports: "The license is missing or invalid. The PLC runs in demo mode." I am not sure whether: The missing SoftMotion license prevents Controlword generation completely. The axis is still not correctly connected to the EtherCAT slave despite operational communication. There is an additional CiA402 configuration step required for the Festo CMMT-AS drive. Has anyone successfully used a Festo CMMT-AS MP drive with CODESYS SoftMotion Generic DSP402 on a WAGO PFC200? Any suggestions on what should be checked next would be greatly appreciated.

Post by dclements on Feature Request: Read-Only References / Pointer-to-Const Support ^{CODESYS Forge talk (Post)}
I would like to suggest adding support for persistent read-only references or pointers in CODESYS, similar to a C++ pointer-to-const (const T*). For example, something conceptually similar to: POINTER TO CONSTANT ST_MyData or REFERENCE TO CONSTANT ST_MyData The important distinction is that the reference itself may still be passed around or reassigned, but the referenced object cannot be modified through that reference. CODESYS currently supports VAR_IN_OUT CONSTANT, which provides read-only reference semantics for parameters, but there does not appear to be an equivalent type that can be stored in a variable or returned from a method. A practical use case is a registry that owns long-lived definitions. The registry needs to retain ownership of the data while downstream systems maintain persistent references to it. Currently, the main options are: Return the struct by value, which loses reference semantics and requires a copy. Return POINTER TO ST_Definition, which allows consumers to modify registry-owned data. Convert the structure into a Function Block and expose a getter-only interface, which provides the desired encapsulation but introduces more complexity and memory overhead. A read-only reference/pointer type would allow libraries to expose persistent, zero-copy access to internally owned data while preserving encapsulation. This would be particularly useful for library APIs and object-oriented CODESYS architectures where ownership of data should remain with one component while other components are allowed to observe it. Similar requests for constant references/pointers have been discussed on CODESYS Forge previously, so this appears to be a recurring use case rather than something specific to one application.

Hello, I’m working on implementing Modbus RTU communication with a Carel controller (CPCO). I want to use the front RS485 interface through the DB9 connector. The issue is that I can’t get the communication working correctly. Below are the steps I’ve done so far: Connected pins 3 and 8 from the DB9 connector to the +/- RX/TX terminals on the Carel side. In the PLC shell, I set serialmode to RS485. In WBM under Administration > Serial Interface > Assign owner of serial interface, I set the port to unassigned. In the device tree, I created Modbus_COM with the following settings: COM port: 1 Baud rate: 19200 Parity: None Stop bits: 1 Created a Modbus client on this COM interface in RTU mode. Under the status tab, I can see it is in running state. On the client, I created a Modbus server and set the Modbus address of my unit to 1. Defined a few channels as FC03 to read holding registers according to the Carel register map. I checked the communication with the Carel controller using a USB-to-RS485 converter connected to my PC, and communication works correctly there. In the status tab, I can see that the Modbus server is polling, but there is no response from the controller. I also tried multiple times swapping A/B lines on the Carel side, but it did not help. Do you have any suggestions on what else I should check?

Under the status tab, I can see it is in running state. On the client, I created a Modbus server and set the Modbus address of my unit to 1. Defined a few channels as FC03 to read holding registers according to the Carel register map. I checked the communication with the Carel controller using a USB-to-RS485 converter connected to my PC, and communication works correctly there. In the status tab, I can see that the Modbus server is polling, but there is no response from the controller. I also tried multiple times swapping A/B lines on the Carel side, but it did not help. Do you have any suggestions on what else I should check?

Post by jasonhogan on Login problem with FileTransfer on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
That’s a classic CODESYS quirk. As soon as you enable AllowFileTransferServices=1, the web server locks down and demands authentication for everything, including WebVisu sessions. Since you're on a Raspberry Pi / Linux, trying to make the built-in CODESYS web server do both secure file handling and unauthenticated kiosk visu is usually a losing battle. A couple of ways to get around this: The cleaner route (separate the jobs): Turn AllowFileTransferServices back off in the config so your kiosk WebVisu opens freely without any login prompts. Then, handle the file download outside of CODESYS — just run a dead-simple Nginx/lighttpd file server or a tiny Python script on the Pi pointed at your export folder (/var/opt/codesys/...). That way your PLC security stays intact, and the kiosk screen just works. If you really want it through CODESYS: Check your Device -> Users and Groups in the IDE. Make sure the Everyone / Anonymous user group actually has explicit view permissions checked for the Visualization. Sometimes when file services are toggled, anonymous users lose the default visu-read rights and get booted straight to the login dialog. URL / Browser trick for kiosk: If the Pi is just opening a local browser on startup, you can sometimes pass the basic credentials in the browser launch script or use a small reverse proxy on localhost to inject the headers automatically so you don't see the popup. Honestly, running a lightweight HTTP/FTP endpoint on Linux (option 1) is by far the least headache.

Post by clesio on CAA.File.Write – Unexpected characters when writing a CSV file ^{CODESYS Forge talk (Post)}
Hello everyone, I am trying to create a routine in CODESYS to export a report to a CSV file using the CAA.File library. The file is created successfully, but I am getting some unexpected/unknown characters in the generated CSV. The problem seems to be related to the SIZEOF() function. I am using it for the szSize parameter of File.Write, as recommended in the CODESYS documentation. However, when I use SIZEOF(), the CSV contains extra characters and parts of previous strings. I also tried using LEN(), but in my application the file is created empty, even though the string and the calculated length appear to be correct. Here is the relevant part of my code: PROGRAM Relatorio VAR // Bool b_Executa_fb_Cria_Arquivo : BOOL; b_Executa_fb_Fecha_Arquivo : BOOL; b_Escreve_dados : BOOL; b_Erro_fb_Escreve : BOOL; //STR s_Nome_Arquivo : STRING; s_Palavra : STRING; s_Palavra_Anterior : STRING; s_Data_Atualizada_Formatada : STRING; s_Dia : STRING; s_Mes : STRING; s_Ano : STRING; s_Hora_Atualizada_Formatada : STRING; s_Hora : STRING; s_Minu : STRING; s_Segu : STRING; //INT i_modo_fb_Cria_Arquivo : INT; i_ErroID_fb_Escreve : INT; //UINT i_Tamanho_Palavra : UINT; // Blocos de Funcao fb_Cria_Arquivo : FILE.Open; fb_Fecha_Arquivo : FILE.Close; fb_Escreve : FILE.Write; // DATA E HORA sc_DataTime : SysTimeRtc.RTS_SYSTIMEDATE; // STRUCT = sc uidResultRtcGet : UDINT; //stGetDate : SysTimeRtc.RTS_SYSTIMEDATE; uidResultConvertToDate : UDINT; uidResult : RTS_IEC_RESULT; END_VAR VAR_INPUT //BOOL b_SET_Executa_fb_Cria_Arquivo : BOOL; b_RES_Executa_fb_Cria_Arquivo : BOOL; b_Executa_fb_Escrita : BOOL; // INT i_Linhas_Cabecalho : INT; i_Linhas_Cabecalho_Anterior : INT; END_VAR // Para Testes s_Nome_Arquivo := 'relatorio/Teste1M.CSV'; i_modo_fb_Cria_Arquivo := 0; // TRATAMENTO DE DATOS DATA e HORA uidResultRtcGet := SysTimeRtcGet(uidResult); uidResultConvertToDate := SysTimeRtcConvertUtcToDate(dwTimestampUtc := uidResultRtcGet, pDate := sc_DataTime); // FORMATA DATA EM UMA STRING s_Dia := UINT_TO_STRING(sc_DataTime.wDay); s_Mes := UINT_TO_STRING(sc_DataTime.wMonth); s_Ano := UINT_TO_STRING(sc_DataTime.wYear); s_Data_Atualizada_Formatada := CONCAT(s_Dia, CONCAT('/', CONCAT(s_Mes, CONCAT('/', s_Ano)))); // FORMATA HORA EM UMA STRING s_Hora := UINT_TO_STRING(sc_DataTime.wHour); s_Minu := UINT_TO_STRING(sc_DataTime.wMinute); s_Segu := UINT_TO_STRING(sc_DataTime.wSecond); s_Hora_Atualizada_Formatada := CONCAT(s_Hora, CONCAT(':', CONCAT(s_Minu, CONCAT(':', s_Segu)))); // ABRE e CRIA ARQUIVO IF (b_SET_Executa_fb_Cria_Arquivo OR b_Executa_fb_Cria_Arquivo) AND NOT(b_RES_Executa_fb_Cria_Arquivo) THEN b_Executa_fb_Cria_Arquivo := TRUE; ELSE b_Executa_fb_Cria_Arquivo := FALSE; END_IF fb_Cria_Arquivo( xExecute := b_Executa_fb_Cria_Arquivo, sFileName := s_Nome_Arquivo, eFileMode := i_modo_fb_Cria_Arquivo, xExclusive := FALSE, ); //i_Tamanho_Palavra := SizeOf(s_Palavra); // ESCREVE NO ARQUIVO fb_Escreve( xExecute := b_Executa_fb_Escrita, hFile := fb_Cria_arquivo.hFile, szSize := SIZEOF(s_Palavra), pBuffer := ADR(s_palavra) ); // FECHA ARQUIVO fb_Fecha_Arquivo( xExecute := b_Executa_fb_Fecha_Arquivo, hFile := fb_Cria_arquivo.hFile ); IF Criacao_Edicao_Arquivos.b_Escreve_Cabecalho THEN CASE i_Linhas_Cabecalho OF 1 : s_palavra := 'ESTERILIZADOR'; 2: s_palavra := 'MAQ4; $R$L'; 3: s_palavra := CONCAT(CONCAT('CLIENTE: ',GVL.sReceitaAtual), '$R$L'); 4: s_palavra := CONCAT(CONCAT('NUMERO LOTE: ',DINT_TO_STRING(GVL.Lote)), '$R$L'); 5: s_palavra := CONCAT(CONCAT('OPERADOR: ', DINT_TO_STRING(GVL.Operador)), '$R$L'); 6: s_palavra := CONCAT(CONCAT('DATA: ', s_Data_Atualizada_Formatada), '$R$L'); 7: s_palavra := CONCAT(CONCAT('HORA: ', s_Hora_Atualizada_Formatada), '$R$L'); 8: s_palavra := '$R$L'; 9: s_palavra := 'PARAMETROS AJUSTADOS $R$L'; 10: s_palavra := CONCAT('TEMPO PRE COND.: ', CONCAT(INT_TO_STRING(GVL.rc_T_PreCondicionamento), ' min $R$L')); 11: s_palavra := CONCAT('PULSOS INERTIZACAO 1: ', CONCAT(INT_TO_STRING(GVL.rc_PulsosInertizacao_1), ' PULSOS $R$L')); 12: s_palavra := CONCAT('PULSOS INERTIZACAO 2: ', CONCAT(INT_TO_STRING(GVL.rc_PulsosInertizacao_2), ' PULSOS $R$L')); 13: s_palavra := CONCAT('PULSOS AERACAO: ', CONCAT(INT_TO_STRING(GVL.rc_PulsosAeracao_2), ' PULSOS $R$L')); 14: s_palavra := CONCAT('PRESSAO DE VACUO 1: ', CONCAT(REAL_TO_STRING(GVL.rc_PV1_max), ' bar $R$L')); 15: s_palavra := CONCAT('PRESSAO DE VACUO 2: ', CONCAT(REAL_TO_STRING(GVL.rc_PV2), ' bar $R$L')); 16: s_palavra := CONCAT('PRESSAO INERTIZACAO 1: ', CONCAT(REAL_TO_STRING(GVL.rc_PN1), ' bar $R$L')); 17: s_palavra := CONCAT('PRESSAO INERTIZACAO 2: ', CONCAT(REAL_TO_STRING(GVL.rc_PN2), ' bar $R$L')); 18: s_palavra := CONCAT('PRESSAO AERACAO: ', CONCAT(REAL_TO_STRING(GVL.rc_PAR), ' bar $R$L')); 19: s_palavra := CONCAT('PRESSAO ETO: ', CONCAT(REAL_TO_STRING(GVL.rc_PressaoETO), ' bar $R$L')); 20: s_palavra := CONCAT('PRESSAO Compl.: ', CONCAT(REAL_TO_STRING(GVL.rc_PressaoETO_2), ' bar $R$L')); 21: s_palavra := CONCAT('MASSA ETO: ', CONCAT(REAL_TO_STRING(GVL.rc_QuantidadeETO), ' Kg $R$L')); 22: s_palavra := CONCAT('TEMPO PRE COND.

Aufgrund einer Schnittstellenänderung muss ich meine Messagebuffer erheblich vergrößern. U.g.
