Post by macman on Codesys 3.5 OPC UA Client to Kepware OPC UA Server ^{CODESYS Forge talk (Post)}
Hi, I have problem with connecting Wago PLC WAGO 750-8212/0025-0002 configured as OPC UA client to Kepware OPC UA Server. I am using Codesys 3.5.19.70. What I did so far. To the Codesys project I added object Data Source Manager and configured connection OPC UA like below: pic 1 Then I can browse the OPC server tags in “Variables” tab after prior trust on the server side of the client certificate created in the “Communication” tab: pic 2 Additionally second certificate has been created in Codesys for runtime process in “Security screen” as well as the server certificate was approved here: pic 3 But when I compiled project, downloaded it to PLC and go to RUN I can’t read selected in “Variables” tab, OPC Server tags. I am getting such error (ID: 7001): pic 4 All two PLC certificates has been trusted in OPC server (Kepware) side: pic 5 and Kepware server configuration look like this: pic 6 I can easily connect using third party OPC UA client UaExpert to Kepware server without problem. In attachment I added also log from Kepware OPC UA server. pic # - this specifies the number of a concrete graphic from one of the collective in attachment

Post by nicetuxedo on Can not activate license on Raspberry pi ^{CODESYS Forge talk (Post)}
Hello everyone, I'm hoping for some assistance with a license activation issue: a software crash has left my license in a strange state. Here is the sequence of events: I purchased a new license for the Raspberry PI from the official CODESYS web store. I opened the CODESYS and started the online activation process using the ticket number I received. During the activation, the CODESYS software threw an exception and crashed. I was not able to see if the activation completed. After restarting CODESYS, I attempted to run the activation process again with the same ticket number. The License Manager now gives me an error stating that the ticket has already been activated/used. I am now stuck because my installation is not licensed, but the activation server believes my ticket has been consumed. Has anyone encountered this before? Is there a way to have the ticket status reset?

Post by forest on SM Drive license error ^{CODESYS Forge talk (Post)}
Hi, when it comes about license, I used INVTmatic Studio, which uses Codesys, for programming INVT plc. I bought Codesys Modbus license, it was not expensive, and then realised that INVT didn't have License Manager option (greyed out in program) which is needed for using of Codesys License. I contacted support from INVT, but developers told me that option is still not available. So depending on environment for programming Codesys, you can or not use Modbus license. Good thing about this version of Modbus TCP it works both direction. I could send commands and receive feedbacks from drive. But communication stops after 30 mins. So I used simple version of ethernet modbus which is somewhere in INVT or Condesys library (I can check tomorrow) which works only one way. I could send cmd to drive, and control it, but didn't have any feedback, like some readings back in PLC. which is bad, but at least I could start it and it didn't fail after 30 mins.

Post by wbj0t on System libs and I/O Drivers ^{CODESYS Forge talk (Post)}
Hi everyone. My question about: where I can learn (read or watch) an info about codesys workflow through the system IO libs? I want to know how to implement I/O drivers by my self. In the system libs I see many interfaces, methods etc... But there is no explanation about them, just names of methods and fields of the FBs. I know about this page: https://forge.codesys.com/drv/io-drivers/doc/Generic/ There is so BIG the device description file and not so clear explaining of the attributes and elements, also some elements or attributes missed at it all. Yes, there are code examples on this page, but, so shortly and, for example, code about Modbus drivers is absent. And even if I try to add the IoDrvFB with lib, I get and error, something like: "failed to load IoDrvFB driver". And what about the book of codesys that written by Gary Pratt? Is there information about system libs and drivers in this book more clearly? Thank you :)

Post by squiggleypuff on Can't Add New Version of Modbus TCP Master ^{CODESYS Forge talk (Post)}
I'm having a tough time trying to get Modbus working on a Festo CPX-E PLC; it throws these pre-compiler errors as soon as I add in my Modbus TCP Master 3.5.12.30 to my project: I'm confused about the C0046 error, as I have IODrvModbusTCP 4.3.0.0 Library installed. So I thought maybe I needed to use the newest Modbus TCP Master 4.3.0.0, which is in my device repository: However, whenever I go to add this underneath the Ethernet adapter (which is version 4.2.0.0), the only TCP Master version available is the old 3.5.12.30 one, even if I have Display all versions checked.: I even went so far as to delete the old version, but then there were no options to add a Modbus TCP Master under my Ethernet adapter. What needs to be done to use the newest Modbus TCP Master? Or are these pre-compiler errors unrelated and I'm missing something? Any help greatly appreciated.

Hello! Raspberry pi 2b just is getting a bit slow so decided to go for a Raspberry 5. Project is now upgraded to suit Pi 64 SL... so, now although everything runs perfectly... for some reason my trends will not save! its driving me nuts... ^Tried merging tasks with main program & trends ^tried re-prioritizing tasks (shifting 1 - 31 etc) ^Recreated the Trend Recording manager from scratch ^Tried swapping persisitant vars to GVL Retains then non-retains... (Project attached is as per before trial&error) Raspberry Pi 2b still runs "perfectly" though its very chuggy (Still saves the trends, note this is of an pretty much identical project minus the device compatibility) Does anyone have any advice to offer? project attached.... I feel it could be outside of Codesys itself causing the issues, but cant see/find anything on the internet to assist (or anyone else with the same problem as me...) Can attach project in another format (non archive) any assistance is much appreciated!

Post by gmau on Station 'xyz': AR aborted by device (alarm.ind): AR consumer DHT expired ^{CODESYS Forge talk (Post)}
Hello, I am writing to You with the problem of Profinet communication in my Codesys V2.5 SP21 project working on Codesys Control RTE V3 x64 device. I have implemented multiple Profinet devices in the network, the Profinet itself is configured properly, based on the hardware and software parameters of the industrial PC (Windows 10 IoT). My Profinet network contains such Profinet devices as a robot, IO-Link master with some devices on it, IO modules, safety, vision sensor (the configuration is attached to this topic). Once every few hours, sometimes more often, sometimes not even once a day, the error show up at one, two or a few random modules at the same time, every one is the same: "Station 'xyz': AR aborted by device (alarm.ind): AR consumer DHT expired". The communication is then lost with that module, but it is up instantly. It is not such a problem when it comes to regular IOs, but with safety or rotation table, it causes errors and machine stops. I have tried multiple solution based on any forum suggestions, manuals, etc., but it is still happening. Mabye when I turned on the Watchdog for this communication, it is happening less times, but still, I could not turning up the Watchdog parameters at the expense of cycle time of the process. The same is with Send Clock, Reduction and DHT. I have one of the ethernet port on the PC configured with CmpEt1000Drv driver. The card itself is Intel Ethernet Connection I219-LM. These devices are connected to one EKI-2728-NI-A Profinet switch (it was changed from the standard non Profinet one, but still nothing has changed). As I said ealier, I am attaching all the configurations for each device and the communication itself - if any of You had the same problems or have any ideas what could be the cause, I would be much gratefull for any help. For now I am out of ideas, if You have any additional question, please ask. Sincerely, PF

Post by alexgooi on OPC-UA and other communication questions ^{CODESYS Forge talk (Post)}
Dear forum, I currently have a big question mark above my head, and maybe this forum can shine some light on the situation. I recently updated to Codesys 3.15 SP19 Patch 6. And now I’m trying to setup the OPC-UA server, besides that I’m trying to connect to the controller with the Codesys V3 (Ethernet) protocol. OPC-UA I have installed the correct licenses on my controller (Runtime and communication). I’m able to connect to the controller with an OPC-UA client, and I’m able to browse the tags, so far so good. Therefore I’m assuming that the OPC-UA server is running on the controller. But now the strange part, in the device security settings I have set the communication Policy to BASCI256SHA256 ( I also have tried the other ones) and the communication mode is set to secure if possible (I also have tried all the other ones) (see picture). With these settings I would assume that I would only be able to login with a Basic256SHA256 policy with a client. But the opposite is true, I am able to login using the no policy mode and when I set it to Basic256SHA256 the client (UA-Expert) notes that this policy is not available on the server. I then check the certificates and I noted that there is no certificate for the OPC-UA server, I tried to generate one but it gave the error that the certificate has not been created by the device (See picture). To summarize I have no clue what is going on, and the controller does the opposite of what I would expect. Codesys Ethernet V3 driver I have a HMI connected to the same controller using the Ethernet V3 driver. But this will not connect. I tried all the Protocols (see picture), with and without the username and password enabled. But it will not connect, when I scan the available servers I can see the controller with the port number that I am expecting, so I’m assuming that the Codesys V3 ethernet driver is up on the controller. Does anyone can give me some direction, because the stuff that I tried doesn’t make sense to me. Thank you in advance

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.

Post by t-probst on Strong Private Key Protection for Encryption Certificates ^{CODESYS Forge talk (Post)}
Hello, We are trying to implement an automated method of adding of a certificate and private key to the Windows certificate store for encrypting CODESYS projects. We want to do this so that users do not have to deal with details of certificates at all and to prevent user error. We are keen on enforcing strong private key protection since it ensures that a password is required for the certificate to be used to decrypt a CODESYS project. When we add a certificate to the certificate store and enable strong key protection using the Microsoft Management Console Certificates snap-in, it works as expected. However, through this method the user may mistakenly not enable strong private key protection. For the certificates we create programmatically (using Microsoft’s Cryptography Next Generation API in .Net 7) bag attributes are added to the certificate and key by the API. These bag attributes are as follows: Bag Attributes localKeyID: 01 00 00 00 subject=C = xx, ST = xxx, O = xxx, OU = xxx, CN = xxx issuer=C = xx, ST = xxx, L = xxx, O = xxx, OU = xxx, CN = xxx -----BEGIN CERTIFICATE----- [encoded certificate] -----END CERTIFICATE----- After using this certificate with bag attributes to encrypt a CODESYS project, it can’t be decrypted, showing this error: "The specified project could not be loaded. Possible reasons might be: - The project file is corrupted or invalid - The project has been saved with a newer version of the programming system. If this is the case, you can open the project in the corresponding version. Choose "Save as..." with the appropriate storage version, and retry again. - You may not have the necessary permissions to lad the project" We know that the bag attributes are causing the issue because if we manually edit the certificate file to remove them before using the certificate to encrypt a project, the project can be decrypted as expected. However, we are unable to automatically enforce strong key protection using this method. Here is a link to a StackOverFlow question that we have posted recently for this issue: https://stackoverflow.com/questions/76922355/enforcing-strong-private-key-protection-for-x509certificate2-objects-in-net-mod Any help is greatly appreciated.

Thanks for your reply. I belive it is contiguous, I'm writing to adress 0 to 4. Or, do you mean something else? Well, something is happening. If I on the client set adress 1,2,3 to true, only 1 is set to true on the server side. On the client side, the data is array of word. But on the server side, the coils are array of bool. Holding register is array of word on server side. Can this be a problem? Attached screenshot of how it looks at the server side.
