The codesys application license allows the use of up to 4 fieldbus instances (eg Modbus). I need to use more instances than that. Can I use the Modbus library instead? Does this usage require a license? Similar to other libraries such as CanOpen, Modbus TCP...

naja die compiled library hast du ja - du hast halt eine exception - und dann wirst du gefragt ob du das ganze Debuggen willst. Die offene Bibliothek wirst du nicht bekommen - daher würde ich so vorgehen: Dein Projekt hier mal anhängen so das man mal draufschauen was du genau aufrufst und wie.

It would be great if there was a thread that had some quick-start links for basic how-to. But one that advanced programmers can jump into. I found this video playlist by SoftMotion-Black, which was very, very helpful: https://www.youtube.com/playlist?list=PLkc8m2OD0r9xJyfTiCBb1vuU_d2yBhjZ_ This person has some other great vids like creating your own custom library, which is awesome for OEMS.

I am struggling with this issue right now (again). I have nested structures with configurable array sizes. In the past I ever used parameter list. Very easy way! As of now I cannot find any solution. Ridiculous that they deprecated it without an alternative solution.

Ich bin leider auch über den Fehler gestolpert, aber selbst in Version 3.5.19.50 ist dieser noch enthalten. Bis 3.5.19.20 kann ich meine Programme noch nutzen. Ab 3.5.19.30 ist der Fehler anscheinend vorhanden. Ich habe leider auch schon einen Haufen Programme mit meiner Library erstellt, somit wäre ein umbenennen nur mit sehr viel aufwand möglich.

To prevent ambiguous use of this enumeration value. Let's say another ENUM is available in your project or in another library which has an enumeration value AM_WRITE, then it is not clear which AM_WRITE you want to assign. By this qualified access to the SysFile.AM_WRITE, it is completely clear for the compiler.

Hi Martin, I got the messagekey of the "upgrade format warning dialog" with key:"<< No Key>>". (please refer to the attachment) Is that means i can't use system.prompt_answers["<<No Key>>"] = PromptResult.OK; to auto-answer 'OK' in this dialog? Is there any other way to auto-answer this dialog? Thanks!

Could this be turned into a library? I'd love for a way to have the main program call a function block method using the program's I2C_master device. I assume I should be passing the master as a variable for the function block, but I don't see how that could be achieved

Post by jeffersonhui on SysProcessExecuteCommand2 terminate CODESYS Forge talk (Post)
Hi, I am using the SysProcessExecuteCommand2 function from the SysProcess library to run the candump command in the PLC's Linux environment. However, the candump command stays running indefinitely. If I was running the candump command from a terminal (via PuTTy, etc), that command usually requires Ctrl+C to terminate. Is there a way to terminate a command that is executed with SysProcessExecuteCommand2?

Post by mgabryel on Problems with CAN 2.0 comunication on Wago PLC (Codesys 3.5) CODESYS Forge talk (Post)
Hello, I am trying to program CAN Bus comunication on WAGO PLC (more precisely on WAGO Touch Monitor model TP600). I am using for this purpose library "WagoAppCanLayer2" from Wago company. My IDE for programming this device is CODESYS V3.5 SP19 Patch 2 + (64-bit). My program is written in Structured text using function blocks from previously mentioned library. Here is code of this program: 1) Variables declarations: PROGRAM PLC_PRG VAR oOpenInterface : WagoAppCanLayer2.FbCanL2Open :=( udiBaudrate := 125000 ); xInterfaceIsOpen : BOOL; sInterfaceInfo : STRING; oReceive : WagoAppCanLayer2.FbCanRx29BitFrame :=( xBufferMode := FALSE, wCanId := 16#181 ); xRecv : BOOL; sReceiveInfo : STRING; oSend : WagoAppCanLayer2.FbCanTx29BitFrame :=( dwCanId := 16#100, //was 16#201 xRtrFrame := FALSE ); xSend : BOOL; sSendInfo : STRING; oCanDiag : WagoAppCanLayer2.FbCanErrorInfo; xRst : BOOL; aSendData : ARRAY [1..8] OF BYTE; bSendLen : BYTE; TON_0 : TON; TON_1 : TON; END_VAR 2) Program body: oOpenInterface( xEnable := NOT xInterfaceIsOpen, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE ); sInterfaceInfo := oOpenInterface.oStatus.GetDescription(); xInterfaceIsOpen S= oOpenInterface.xValid AND NOT oOpenInterface.xError; oReceive( xEnable := xInterfaceIsOpen, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE, xRxTrigger := xRecv ); sReceiveInfo := oReceive.oStatus.GetDescription(); IF NOT xRecv THEN IF oReceive.bRxNBytes > 0 THEN oReceive.aRxBuffer[1]; oReceive.aRxBuffer[2]; oReceive.aRxBuffer[3]; oReceive.aRxBuffer[4]; oReceive.aRxBuffer[5]; oReceive.aRxBuffer[6]; oReceive.aRxBuffer[7]; oReceive.aRxBuffer[8]; END_IF xRecv := TRUE; END_IF aSendData[1] := 224; aSendData[2] := 13; aSendData[3] := 14; aSendData[4] := 15; aSendData[5] := 222; aSendData[6] := 13; aSendData[7] := 14; aSendData[8] := 15; bSendLen := 8; TON_0(IN:= NOT TON_1.Q, PT:= T#2S , Q=>xSend, ET=> ); TON_1(IN:= TON_0.Q, PT:= T#2S , Q=>, ET=> ); oSend( xEnable := xInterfaceIsOpen, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE, aTxBuffer := aSendData, bTxNBytes := bSendLen, xTxTrigger := xSend ); sSendInfo := oSend.oStatus.GetDescription(); oCanDiag( xEnable := TRUE, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE, xTriggerResetCounter := xRst, xValid=> , xError=> , oStatus=> , wBusState=> , wBusDiag=> , uiRxOverflowsL2=> , uiTxOverflowsL2=> , uiRxOverflows=> , uiMsgTimeouts=> , uiBusOffs=> , uiBusWarnings=> ); Program first opens comunication on CAN 2 device and then periodically try send one CAN data frame. After starting program CAN 2 interface is properly open. The xSend variable is toggling with period 2s. When program sends data an "Tx overflow" error appears. When I am watching CAN_H line on DSub 9 socket i am not able to see proper CAN frames - see screenshot attached to this message. Could somebody help me determine what is wrong with this program. Best regards

Post by ofey on EtherCAT fieldbus CODESYS Forge talk (Post)
Hi, everyone! I'm trying to set up a PLC controller and a connection to an EtherCAT slave device in Codesys. I want to create a flexible program that I can upload to multiple controllers with different remote IO connected (same program). On one plant i may have 5 AI-cards and 3 DO-cards, and on another I may have 4 AI-cards and 2 DO-cards. For not needing to maintain several different programs wih different devices defined in the program (one for each set up) I thought that using a remote IO would make it easier having a single program. That way I could refer to different memory addresses instead of predefined slots/channels and IO's, that would give me errors if there was a different IO on the plant than what the program expected. When I tried setting up the etherCAT master, I saw that I had to define the etherCAT slave devices with the different IO'cards for me to be able to refer to the memory addresses in a PRG. Exactly what I was trying to avoid. My setup is something like a program that can handle 16 separate pump controls. In a year maybe 6 plans get deployed, and depending on how large the project is, the number of pumps can vary between 4 and 16. And the managers dont want to have IO's for all 16 pumps on every cabinet, and I dont want to maintain 16 separate projects files in case of updates etc. I thought the best way to tackle this was having a single project that read/write data to the different pump IO's by remote IO (fieldbus ethercat) addresses. And the number of pump controls are activated by an external GUI. If pump 1-6 is activated by the GUI, then the PLC-program tries to read/write input/outputs from predefined addresses for the expected IO's. My test setup is a PFC200 WAGO controller and a EtherCAT fieldbus coupler (750-354) with some IO. I hope I didn't explain this too horrible, and if there is a more easy and elegant solution for this challenge I appreciate a feedback on this.

Hallo, die Option CallVisuServicesDirectly=1 verändert das Verhalten leider nicht. In Codesys gibt es noch in den Einstellungen der Webvisu den Eintrag unter Login-Visualisierung. Das Löschen dieses Eintrages ergibt aber auch keine Änderung. Evtl. wird bei der neuen Codesys Version für die Webvisu eine https Verbindung vorausgesetzt. Zu dem Thema bin ich im Thread https://forge.codesys.com/forge/talk/Visualization/thread/5767230df2/ auf die Beschreibung im Installationsverzeichnis unter file:///C:/Program%20Files/CODESYS%203.5.20.0/GatewayPLC/Documentation/WebServerSSL_de.pdf gestoßen. Allerdings gibt es dort Diskrepanzen zwischen der Verzeichnisstruktur auf meinem Gerät und in der Beschreibung. Also werde ich in dieser Richtung weiterforschen. Vielleicht hat noch jemand einen Tip, wie die Webvisu schnell auf https umgestellt werden kann. Vielen Dank!

Post by mariapaola on Port instantiation of serial interface in WAGO PLC using Modb_L05.lib in CoDeSys v2.3 CODESYS Forge talk (Post)
Hi, Would really appreciate your insights in this issue I have. I am currently using a WAGO 750-881 with multiple IO devices. For one of them I already occupied the MODBUS Master configuration tool so I cannot overwrite it for my other devices. I have a total of two serial interfaces WAGO 750-652. The first one is instantiated in COM2 and doesn't need any protocol since the information comes in an specific formatting that need little code to differentiate between needed info. This one is working just fine. The second one is where I have an issue. I have tried to instantiate the port using MODBUS library modb_L05.lib to properly receive the data from an ARDUINO and I am absolutely unable to open the port: Signal DEVICE2.fbModbus.MODBUS_EXT_MASTER.Interface.Com_Port_Ist_Offen is never TRUE, among with all other signals from that interface, while signal DEVICE1.COM2.Com_Port_Ist_Offen is TRUE, and the other signals also read as TRUE or FALSE. I have tried instantiating the second one as the first one, changing COM3 to COM4, I've tried a lot of things but it wont ever open the channel. I don't know if you have any recommendations for me. For both physical modules, both witness LEDs A and E are on. First one is instantiated like this: PROGRAM DEVICE1 VAR wBaudRate : WORD := BAUD_9600; bDataBits : BYTE := 8; bParity : BYTE := 0; bFlowControl : BYTE := 3; (RS422 FullDuplex with continous send) i : INT; COM2 : SERIAL_INTERFACE; xOpenPort2 : BOOL := TRUE; ( Flag to open the Port ) xInitPort2 : BOOL; ( Flag to initiallize the Port ) ReceiveBuffer2 : typRing_Buffer; END_VAR COM2( bCOM_PORT_NR := 2, cbBAUDRATE := wBaudRate, cbsBYTESIZE := bDataBits, cpPARITY := bParity, csSTOPBITS := STOPBITS_1, cfFLOW_CONTROL := bFlowControl, utRECEIVE_BUFFER := ReceiveBuffer2, ptSEND_BUFFER := ADR(SendString2), xINIT := xInitPort2, xOPEN_COM_PORT := xOpenPort2, iBYTES_TO_SEND := LEN(SendString2)+1, xSTART_SEND := xSendActive2 ); Second one like this: PROGRAM DEVICE2 VAR COM4 : SERIAL_INTERFACE; xInitPort4 : BOOL := TRUE; xOpenPort4 : BOOL := TRUE; ReceiveBuffer4 : typRing_Buffer; fbModbus : MODBUS_EXTENDED_MASTER_RTU; fbError : enumMB_ERROR; stQuery : typModbusExtendedQuery; stResponse : typModbusResponse; au16Data : ARRAY[0..14] OF WORD; i : INT; tPoll : TON; END_VAR COM4( bCOM_PORT_NR := 4, cbBAUDRATE := BAUD_9600, cbsBYTESIZE := 8, cpPARITY := 0, csSTOPBITS := STOPBITS_1, cfFLOW_CONTROL := 2, ( RS-485 half-duplex ) utRECEIVE_BUFFER := ReceiveBuffer4, xINIT := xInitPort4, xOPEN_COM_PORT := xOpenPort4, xSTART_SEND := xSendActive4, ); stQuery.SlaveAddress := 1; stQuery.FunctionCode := 3; stQuery.Read_StartAddress := 0; stQuery.Read_Quantity := 15; (Poll code) fbModbus( ENABLE := TRUE, bCOM_PORT := 4, ( COM4=> 750-652 port ) cbCOM_BAUDRATE := BAUD_9600, cpCOM_PARITY := 0, csCOM_STOPBITS := 1, cbsCOM_BYTESIZE := 8, cfCOM_FLOW_CONTROL := 2, TimeOut := T#500ms, StartFunction := xStart, ExtQuery := stQuery, Response := stResponse, MB_Error => fbError ); FOR i := 0 TO 14 DO au16Data[i] := stResponse.Data[i]; END_FOR;

Post by sahin6033 on DSE M840-001-02: DSEServiceTool transfers CodesysApp.pkg successfully, but device shows “No application loaded CODESYS Forge talk (Post)
Hi, I am trying to load a test application into a DSE M840-001-02 display, but after reboot the device still shows: “No application loaded” I would like to understand whether the problem is in my project, the package creation process, or firmware/runtime compatibility. Hardware Device: DSE M840-001-02 Firmware used: M840 MKII Firmware File v4.1.2 Software CODESYS V3.5 SP12 (32-bit) DSE CODESYS Package v1.5.44 DSEServiceTool What I did Created a new empty Standard Project Selected target/template: M840-02 V4.1 Used a minimal ST program only: PROGRAM PLC_PRG VAR xAlive : BOOL := TRUE; END_VAR Confirmed: project builds PLC_PRG is assigned to MainTask created Boot Application Generated CodesysApp.pkg Put the M840 into bootloader mode Sent the package using DSEServiceTool DSEServiceTool result Transfer completes successfully and I get: connection accepted 100% download package ACK <status>OK</status> ** Example log:** Searching for controllers.... sendPackageToController: waiting for incoming data connection... sendPackageToController: connection accepted... <status>Downloading</status> <percent>20</percent> <percent>40</percent> <percent>90</percent> <percent>100</percent> sendPackageToController: sent 112cb8 bytes OK Package ...\CodesysApp.pkg transferred to controller c0a80101 OK sendPackageToController: package ACK <status>OK</status> Actual result After reboot, the display still shows: “No application loaded” Additional issue I also saw earlier At one stage I also had these fatal errors in CODESYS: [FATAL ERROR] Unresolved reference: 'IOMGRLOCKENTER' [FATAL ERROR] Unresolved reference: 'IOMGRLOCKLEAVE' I checked library versions and adjusted them to: IoDrvBase = 3.5.5.0 IoStandard = 3.5.10.0 Also, I am using CODESYS SP12, which I understand is the correct version for DSE M840. My questions If DSEServiceTool shows Status OK and package ACK, but the device still says “No application loaded”, does that mean: the .pkg was transferred but not accepted as a valid application? the package was built incorrectly? the boot application / runtime / firmware versions are still mismatched? What is the correct procedure to generate CodesysApp.pkg for M840-02 V4.1? Is there any known compatibility issue between: DSE CODESYS Package 1.5.44 M840 MKII Firmware 4.1.2 CODESYS 3.5 SP12 Has anyone successfully loaded even a minimal empty test project into M840-001-02, and if so, what exact versions/process did you use? Any help would be appreciated.

Post by alexschooneveld on OPC UA PubSub SL 1.3 — UADP WriterGroup with assigned PSS.SecurityGroup still publishes plaintext CODESYS Forge talk (Post)
I am currently investigating an OPC UA PubSub connection over UDP. When I don't use encryption, the publish and subscribe are working correctly. But with encryption it does not. Environment OPC UA PubSub SL 1.3.0.0 (namespace UADP) OPC UA PubSub Security 1.3.0.0 (namespace PSS) OPC UA PubSub Base 1.3.0.0 (namespace PSB, incl. PSS.SecurityGroup / PSS.CONFIG) Programmatic PubSub in a CFC: UADP.Configuration → UADP.Connection → UADP.writerGroup → UADP.writer → writerDataSet, plus a CyclicCall gated by xEnable. Goal: publish secured UADP, SignAndEncrypt, policy PubSub-Aes256-CTR. What I do (one-shot, before xEnable := TRUE): fbSecurityGroup.SetInitialValue( 'http://opcfoundation.org/UA/SecurityPolicy#PubSub-Aes256-CTR', PSB.SECURITY.SIGNING_AND_ENCRYPTION); stSecurityCfg := fbSecurityGroup.GetConfig(eErrorID => eError); // eError=NO_ERROR, udiEncryptionKeySize=32 eError := fbSecurityGroup.SetSecurityKeys(udiTokenId, ADR(abyKey), SIZEOF(abyKey), 2436001000); // eError=NO_ERROR, SIZEOF=68 // writerGroup.itfSecurityGroup := fbSecurityGroup -- set in the WriterGroup block's Parameters (a per-scan code write got overwritten) What I verified eError = NO_ERROR after both GetConfig and SetSecurityKeys; udiEncryptionKeySize = 32. Key length = 68 bytes (signing 32 ‖ encrypt 32 ‖ nonce 4). itfSecurityGroup is set via the WriterGroup's Parameters (so it isn't clobbered each scan). Init runs before xEnable (the writer doesn't run with xEnable=FALSE). The UADP.writerGroup FB exposes only itfSecurityGroup for security — no SecurityMode/MessageSecurityMode property. Result: the published datagrams are still plaintext — ExtendedFlags1 = 0x01 (security bit 0x10 clear), no security header: b1 01 29 00 0f 16 00 … (PublisherId 41, WriterGroupId 22, RawData, no security) Questions With UADP.writerGroup, is assigning a configured + keyed PSS.SecurityGroup to itfSecurityGroup sufficient to enable message security, or is there an additional step/property/method to switch the WriterGroup to SignAndEncrypt? At what point in the WriterGroup lifecycle is itfSecurityGroup read? Must it be assigned/keyed before xActive, and does the group need a stop→start to pick it up? Is there a required call order, and does SetSecurityKeys need to be called once or repeatedly? Should security be configured on the Connection/Configuration level rather than (or in addition to) the WriterGroup? Is there a working example of secured (SignAndEncrypt) programmatic UADP publishing with this library, or a known limitation in 1.3? How can I read back at runtime whether security is actually active (via itfDiagnostics or similar)? Additional information I can confirm that the consumer side works — i.e. a standard subscriber decrypts the same keys fine — so the keys/profile aren't the issue. The Wireshark capture of the published message is: 0000 b1 01 29 00 0f 16 00 df 0d bb 25 01 00 0e 00 1b ..).......%..... 0010 0e 00 00 00 00 00 00 00 ........
