Post by denkihitsuji on Content update through Data URI on Web Brower on Visualization Toolbox ^{CODESYS Forge} ^talk ^(Post)
Objective: I want to dynamically update the content with strings and JPEG images received from a TCP/IP socket. For this purpose, I am exploring the possibility of utilizing the Web Browser feature of the Visualization toolbox. Example: In a standard web browser, entering data:text/plain;charset=utf-8;base64,SGVsbG8gc3RyYW5nZXI= in the URL window will display "Hello stranger" on the webpage. Issue: When attempting to use this method in the Web Browser of the Visualization toolbox, the content does not display as expected. Instead, it shows the error:'Navigation to the webpage was canceled.'. Request: I seek guidance on how to resolve this issue so that the Web Browser in the Visualization toolbox correctly interprets and displays the data URI content. Alternative Solution Welcomed: Or, if it is possible to directly use Codesys Structured Text (ST) variables within an HTML page, this approach would also meet my requirements. Thank you for your attention.

Post by egau on Hard shutdown: no code on device after power on ^{CODESYS Forge} ^talk ^(Post)
Hi, We have a machine running Codesys on a Windows IPC (CODESYS Control Win v3 - x64). When we hard shutdown the machine, the code on the PLC sometimes becomes "corrupted" after a power on (When trying to login to the PLC, we get the message "The application 'Application' does not exist on device."). I've noticed these errors in the logs, but I'm not sure what to make of them. We are not using any RETAIN variables in our code, although I'm not sure about referenced librairies. (we are using the persistence manager). I'm pretty sure that not doing a graceful shutdown is the root cause of this. This being said, what is the proper way of doing a graceful shutdown? Is putting the Codesys application in "stop" sufficient? I know how to implement this, so if it works then it would be a quick fix. However, I think we need to add a UPS, which would detect power loss and inform the PLC that it needs to initiate its shutdown, and then the PLC would shutdown gracefully. Any help with this will be greatly appreciated :)

Post by r-niedermayer on OPC UA subscriber not operational ^{CODESYS Forge} ^talk ^(Post)
Hi. As far as projects in "old version"s are concerned, these can be upgraded to newer versions at any time. To do this, the device must be updated accordingly and the copilers and library versions must be adapted. You can find instructions on how to proceed in the online help/FAQ: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_changing_compiler_version.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_cmd_update_device.html See also 4.3.22.4 "How to open an Example Project" within the following pdf for more details on the single steps: https://forge.codesys.com/lib/counit/tickets/_discuss/thread/3e991befbc/ca97/attachment/Public%20FAQ-v13-20240610_075228.pdf Regaring your OPCUA connection state always showing just "DISABLED", without knowing both sides of the assembly in detail, one can only approach the problem theoretically. We can give a chekclist on how to proceed: Fist, please recheck the communication settings in the OPC UA connection function block to ensure that the server URL, endpoint URL, and other settings are correct and match the configuration of the OPC UA server. Verify that the OPC UA server is running and accessible. -You can try to connect to the OPC UA server using a separate client, such as UAExpert, to ensure that the issue is not related to the OPC UA server itself. Test the security settings in the OPC UA connection function block to ensure that the correct security policy and certificate are selected. If you are using a dynamic connection to the OPC UA server, probe that the connection settings are correctly configured and that the OPC UA client is able to establish a connection to the OPC UA server. Also, please loock into the log files for any errors related to the OPC UA connection function block, these should be listet there. The log files may also provide additional information about the issue and help you to further troubleshoot the problem. FYI - Please see https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_obj_data_source_communication_opc_ua_server.html: Her you can finde the Communication settings via OPC UA Server -> layout Browse Live Server: The client connects to the server and detects the existing variables and types. From Information Model The client reads the data structure (layout) of the OPC UA Server from the information model set here and as a result receives the information about available variables and types. A connection to the server is not required. The list contains the information models installed in the OPC UA Information Model Repository. "Read Connection" Settings from IEC Variable (option set): - The connection settings used by the device are not read here from the dialog, but at runtime from the IEC variable specified here. - For this possibility, please see the Using a Dynamic Connection to an OPC UA Server (https://content.helpme-codesys.com/en/CODESYS%20Communication/_comm_use_dynamic_opc_ua_server_comm_settings.html) The settings for the communication of a Client-data source to an OPC UA Server can also be dynamically configured from the IEC code and can also be changed at runtime. For such a purpose, a structure is available in the DatasourceOpcUAServer library (For a description of the OPC UA Server, there is one included in the standard installation of CODESYS, https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_encrypt_communication_data_sources_opc_ua_client.html)

Post by jackbrady on Function Blocks and arrays of function blocks ^{CODESYS Forge} ^talk ^(Post)
Hello, I am new to Codesys and PLC programming in general (please go easy ha!) I'm not looking for code to be written for me just some help and pointing in the right direction. I am writing some code to send commands to a relay based on input values (to put it simply). Quite basic stuff. I have wrote a function block that takes a global variable (Open_command:BOOL) and outputs to another global variable (Opened : BOOL). The function block is simulating a device so I'll eventually get the globals from that. I now need to create multiple versions of this function block/ device (lets say 100) but I need each iteration of that function block to reference it's own relevant global variable. I think that the best way of doing this would be to use arrays, although I could be wrong. I am aware that for up to 100 instances I could very well manually assign everything but that seems rather time consuming and I want a fancier way of doing it. Here is a very basic example of what I am looking to do, please note I have not written this in proper code it's just to show what I mean. Global Variables V[0-100] int Open_command [0-100] Bool Opened [0-100] Bool Function Block var input x : BOOL Var output y : BOOL if x then y = TRUE ELSE y = FALSE The input to my function block will be Open_command, output will be Opened Example code. If V[x] > 10 then Open_command [x] = TRUE ELSE Open_command [x] = FALSE (So when V1 goes above 10 I need Open_command1 = TRUE therefore initiating FB1 output. V2 > 10, open_command2 = True > FB2 output V3 > 10, open_command3 = True > FB3 output ... ... ) What I can't seem to figure out is how to tie all this together, I have read through the codesys documentation and if anything it has confused me more! ha. Apologies for the poorly written post but hopefully you understand what I am trying to get at. Thanks, Jack

Post by ppix on Establishing TLS Connection with MQTT Broker using MQTT Client SL Package ^{CODESYS Forge} ^talk ^(Post)
I’m currently working on establishing a TLS connection with an MQTT broker using the MQTT Client SL package in CODESYS. While I’ve successfully established communication with the broker without TLS, I'm encountering issues when trying to enable TLS. In the 'MQTT Explorer' application, I can easily upload the server certificate (.crt), client certificate (.crt), and client key (.key). However, in CODESYS, I can’t find a way to upload my client key (.key file). Here's a summary of my current setup: Certificates: I have uploaded both the client and server certificates to the certificate store under the 'Trusted Certificates' folder in the security screen. TLS Context Initialization: Despite setting the _sCommonName as the name of my client certificate, a new self-signed certificate is created and placed within the device’s certificates. I then need to manually move this certificate to the trusted certificates folder. This results in three certificates in my trusted certs folder: client cert, server cert, and the newly created cert. _ciDefaultCertInfo : MQTT.NBS.CERT_INFO := (psInfo := ADR(_sCommonName), udiSize := TO_UDINT(LEN(_sCommonName))); // CN of the certificate (common name) _sCipherList : MQTT.NBS.CIPHER_LIST := STRUCT(psList := ADR('HIGH'), udiSize := 4); // Cipher string see https://www.openssl.org/docs/man1.1.1/man1/ciphers.html _tlsContext : MQTT.NBS.TLSContext := ( sUseCaseName := _sCommonName, // A certificate is stored in the certificate store with the use case name. You can choose any name. Here we use the common name. ePurpose := MQTT.NBS.PURPOSE.CLIENT_SIDE, // For client certificates set this to NBS.PURPOSE.CLIENT_SIDE sTLSVersion := '1.3', // The TLS version sCipherList := _sCipherList, // Set the cipher list sHostname := sHostname, // The hostname of the broker udiVerificationMode := 2, // 2 => Active Peer verification ciCertInfo := _ciDefaultCertInfo, // Set the cert info itfCertVerifer := 0); // 0 => No Verifier mqttClient : MQTT.MQTTClient := (xUseTLS:=TRUE, itfTLSContext := _tlsContext, itfAsyncProperty := _asyncProperty); Additional Details: In the client FB, I’ve set uiPort:= 8883, xUseTLS:= TRUE, and configured itfTLSContext as mentioned above. The certificates are encrypted with SHA256RSA. sHostname is the IP address of my broker. I’ve attached a copy of the client FB, which shows straight lines where variables are assigned and boxes where they are not. I am currently trying this on the only 2 compatible versions of COSDESYS with my controller (V3.5.15.20 and V3.5.18.40) My Question: How do I correctly set up this mTLS connection? What might I be missing? Any guidance or suggestions would be greatly appreciated, especially considering I’ve already successfully established a non-TLS connection with the same broker. Thank you in advance for your help!

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 jari-koivuluoma on Problem trying Net Base Services 3.5.15.0 TCP connection ^{CODESYS Forge} ^talk ^(Post)
I have a need to send messages between 2 PLCs and I cant use network variables (because of size limit) so I tried writing this simple test program. This seems to work fine. I can send messages back and forth when a first "Start server" and then "Connect client". See the attached image. However, if I disconnect the client by setting ClientConnect to false and try to re-connect then the TCP_Client just gives me TIMEOUT error. When I stop and start the server again, then Im able to reconnect. How is this supposed to work? Why reconnecting wont work. There is not other way of disconnecting the client than setting xEnable of the TCP_Client to false. This is just a testing program and I will try it on 2 seperate devices once this works.

Post by ihatemaryfisher on Sorting array of any-sized structure ^{CODESYS Forge} ^talk ^(Post)
In my machine's operation, I need to display multiples tables containing arrays of structured variables. The arrays change during operation, and my supervisor has advised me to write a new bubble-sort for each array. I think I can make a function to sort an array of any data type. This was my own project, and I'm a relatively new coder. I want to know the weaknesses in my approach, and a better method, if one exists. As far as I can test, the function accepts an array of a structured variable of any size, and sort it by any VAR in that structure. But it relies heavily on pointers, which I've heard are bad practice? Function call: // SORT BY BYTE-SIZED VAR IF xDoIt[6] THEN FUNBubbleSortSansBuffer( IN_pbySourcePointer := ADR(astArray[1]), // address of first byte in first element of array IN_pbyComparePointer:= ADR(astArray[1].byCompByte), // points to first byte of the comparing variable (variable you sort by) IN_uiStructureSize := SIZEOF(TYPE_STRUCTURE), // size, in bytes, of the structured variable IN_uiCompareSize := SIZEOF(astArray[1].byCompByte), // size, in bytes, of the comparing variable (variable you sort by) diArrayElements := UPPER_BOUND(astArray,1), // number of elements in array IN_xSmallToLarge := xSortOrder // whether to sort by small2large or large2small ); END_IF Function: FUNCTION FUNBubbleSortSansBuffer : BOOL VAR_INPUT IN_pbySourcePointer : POINTER TO BYTE; // points to beginning of array (first byte of first element) IN_pbyComparePointer: POINTER TO BYTE; // points to first byte of the comparing variable (variable you sort by) IN_uiStructureSize : UINT; // size, in bytes, of the structured variable IN_uiCompareSize : UINT; // size, in bytes, of the comparing variable (variable you sort by) diArrayElements : DINT; // number of elements in array IN_xSmallToLarge : BOOL; // whether to sort by small2large or large2small END_VAR VAR j : DINT; // repeat iteration over array until array ends i : DINT; // iterarte over array, swapping when necesary k : DINT; // iterator from 1 to size of structure (stepping 'through' a single element in array) dwSize : DWORD; // internal var for use in MEMUtils.MemCpy(<size>) // FOR SORTING BY BYTE VAR pbySourcePointer : POINTER TO BYTE; pbySourcePointer2 : POINTER TO BYTE; pbyComparePointer : POINTER TO BYTE; pbyComparePointer2 : POINTER TO BYTE; pbyPointerToBuffer : POINTER TO BYTE; // pointer to single byte buffer byBufferByte : BYTE; // single byte buffer END_VAR dwSize := UINT_TO_DWORD(IN_uiStructureSize); // get structure size (number of bytes) pbyPointerToBuffer := ADR(byBufferByte); // assign pointer to address of buffer byte (because MEMUtils.MemCpy requires a pointer input) CASE IN_uiCompareSize OF // depending on the size of the VAR to sort by (current functionality for BYTE and WORD/INT 1: // BYTE (8 BIT) FOR j := 1 TO diArrayElements DO // for number of elements in array FOR i := 1 TO (diArrayElements-1) DO // same thing, but row[i+1] row is included in swap logic pbySourcePointer := IN_pbySourcePointer + dwSize*(i-1); // point at #1 byte in array element[i] pbySourcePointer2 := pbySourcePointer + dwSize; // point at #1 byte in array element[i+1] // NOTE: because of memory locations, each array element is offset from one another by a number of bytes equal to the size of the structure // We can "walk" from array[i] to array[i+1] via steps equal to the size of the structure // e.g., ADR(array[i+1]) == ADR(array[i]) + SIZEOF([array datatype]) pbyComparePointer := IN_pbyComparePointer + dwSize*(i-1); // point to sorting variable in array element[i] pbyComparePointer2 := pbyComparePointer + dwSize; // point to sorting variable in array element[i+1] // using sort order (small -> large/large -> small) IF SEL(IN_xSmallToLarge, (pbyComparePointer2^ > pbyComparePointer^),(pbyComparePointer2^ < pbyComparePointer^)) THEN // This is where it gets tricky. We've identified pointers for the starting bytes of aArray[i] and aArray[i+1] // and we know the size of aArray[i]. We are going to swap individual bytes, one at a time, from aArray[i] and aArray[i+1] // this allows us to use only a single byte var as a buffer or temporary data storage // e.g., consider a structure consisting of a word, a byte, and a string. it is stored like this // |------WORD-------| |--BYTE-| |STRING------...| // astArray[1] == 1000 0100 0010 0001 1100 0011 1010 1010.... etc // astArray[2] == 0001 0010 0100 1000 0011 1100 0101 0101.... etc // performing a single swap (copy into a buffer, etc.) of the first byte of each array element creates this // astArray[1] == 0001 0100 0010 0001 1100 0011 1010 1010.... etc // astArray[2] == 1000 0010 0100 1000 0011 1100 0101 0101.... etc // incrementing the pointer adresses for the swap by 1 and swapping again swaps the next byte in each array element // astArray[1] == 0001 0010 0010 0001 1100 0011 1010 1010.... etc // astArray[2] == 1000 0100 0100 1000 0011 1100 0101 0101.... etc // continuing this from k to SIZEOF(TYPE_STRUCTURE) results in a toally swapped row FOR k := 1 TO IN_uiStructureSize DO // copy single byte[k] of array element 1 to buffer MEMUtils.MemCpy(pbyDest := (pbyPointerToBuffer), pbySrc := (pbySourcePointer+k-1), dwSize := 1); // copy single byte[k] of array element 2 to 1 MEMUtils.MemCpy(pbyDest := pbySourcePointer+k-1, pbySrc := (pbySourcePointer2+k-1), dwSize := 1); // copy buffer to byte[k] array element 2 MEMUtils.MemCpy(pbyDest := (pbySourcePointer2+k-1), pbySrc := pbyPointerToBuffer, dwSize := 1); END_FOR END_IF END_FOR END_FOR
