Post by hppatrick on Datenkonvertierung für ein SPS-AO-Modul ^{CODESYS Forge talk (Post)}
Hi Leute , ich bin neu hier im Forum und habe seit kurzer Zeit mein eigenes SPS-Projekt. Ich stoße hin und wieder an Probleme aber habe diese auf kurz oder lang gelöst. Nun zu meinem Problem: Als Projekt habe ich eine Kühlwassersteuerung , die einen Relativdruck einließst, und anhand desssen Werte dann einen Frequenzumrichter ansteuert. Z. Bsp. 5Bar -> FU auf 70Prozent. Ich lese in Codesys den Analogwert mit der Wago A20_750_455_020 ein. Dieser Wert wird umgerechnet mit LIN_TRAFO in 0-10 (Bar)und und wird dann über einen PID Regler geregelt. (Bibliothek UTIL). Dieser Wert wird dann wieder für die Ausgangskarte Umgerechnet (LIN_TRAFO) . Nun zu meinem Problem : Die Ausgangskarte nimmt nur einen Word Datentyp und meine Bausteine haben den REAL Datentyp. Wenn ich einen Konvertierungsbaustein nehme, Schmeist mir Codesys einen Fehler und das Programm wird geschlossen. Könnt Ihr mir helfen? Vielen Dank im Voraus (Datei habe ich angehängt). Die Ausgangskarte ist eine Wago 750-555-08

Post by mubeta on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Hello everyone, I have a very simple program for the process, but it's driving me crazy and I can't see the problems I'm left with: Short topological description: Dual Core Berghof controller with softmotion runtime version 3.5.19.30; Two axes with servodrive on canopen bus, clocked distributed from master; Ethercat I/O node; 2 ms ethercat task, 2 ms canopen bus cycle time; I/O objects of the canopen master and canopen drives connected to the ethercat task cycle; Problem 1: Two separate programs each manage their own axis and drive, with separate state machines. A first axis moves primarily in velocity, except having to position itself absolutely at a predetermined point at the end of the job; the second axis, on the other hand, is a paper unwinder that changes, for each job cycle, from actions in absolute, relative, and cam displacement with the master axis. Well, the state machine of both axes was written in such a way as to call running the useful FB and change it on state change in this way: CASE i_stateMachine OF 0: o_Power(Enable := TRUE, bRegulatorOn := FALSE, bDriveStart := FALSE, Axis := o_PaperUnwinderAxis); o_MoveAbs(Execute := FALSE, Axis := o_PaperUnwinderAxis); o_MoveRel(Execute := FALSE, Axis := o_PaperUnwinderAxis); o_CamSelect(Execute := FALSE, Master := o_MachineAxis, Slave := o_PaperUnwinderAxis, CamTable := cam_PaperUnwinder); o_CamIn(Execute := FALSE, Master := MachineEncoder, Slave := o_PaperUnwinderAxis); o_CamOut(Execute := FALSE, Slave := o_PaperUnwinderAxis); o_SetPosition(Execute := FALSE, Axis := o_PaperUnwinderAxis); IF ... THEN i_StateMachine := 10; END_IF; 10: o_Power( Enable := TRUE, bRegulatorOn := TRUE, bDriveStart := TRUE, Axis := o_PaperUnwinderAxis ); IF o_Power.Status THEN i_StateMachine := 20; END_IF; 20: (* Avanzamento carta *) o_MoveAbs( Execute := TRUE, Position := o_Somewhere, Velocity := 25.0, Acceleration := 3666.7, Deceleration := 3666.7, Jerk := 48000.0, Direction := MC_DIRECTION.positive, Axis := o_PaperUnwinderAxis ); IF o_MoveAbs.Done THEN o_MoveAbs(Execute := FALSE, Axis := o_PaperUnwinderAxis); i_StateMachine := 30; END_IF 30: d_HomingPosition := ...; o_SetPosition( Execute := TRUE, Position := d_HomingPosition, Mode := FALSE, Axis := o_PaperUnwinderAxis ); (* ... *) IF o_SetPosition.Done = TRUE THEN o_SetPosition(Execute := FALSE, Axis := o_PaperUnwinderAxis ); o_LogServer.Append(sMessage := '...', lscClass := LOGSERVER_CLASS.ALWAYS, sdt := o_CommonsMgrData.systime.sdtLocal); i_StateMachine := 40; END_IF; 50: ... The code above is a sketchy example of what I wanted to write. But it gives me a spot problem: in some, the state change results in a drive error, which is unrecoverable except with a reinitialization via SM3_ReinitDrive(). Things are improved a little if in the program I always run the call of all softmotion blocks in this way: o_Power(Axis := o_PaperUnwinderAxis); o_Jog(Axis := o_PaperUnwinderAxis); o_Halt(Axis := o_PaperUnwinderAxis); o_MoveAbs(Axis := o_PaperUnwinderAxis); o_MoveRel(Axis := o_PaperUnwinderAxis); o_CamIn(Master := MachineEncoder, Slave := o_PaperUnwinderAxis); o_CamOut(Slave := o_PaperUnwinderAxis); If I don't execute all the calls of all the motion FBs used, when exchanging machine state often (but not always), the axis goes into error with event id THE_FB_WASNT_CALL... Done a little diagnostics it seems that the FBs return the bDone, before they are completely terminated. I tried doing the machine state exchange not with the bDone bit of the FBs, but with the 'standstill' state of the axis. It didn't seem to change anything. Problem 2: During the use SM3_ReinitDrive() I get the erro in the log: "NetID 0: SDO read error for object 16#607C..." Assuming that the device involved it's one of the two servodrive, (no others device are present in the network), I don't found any object 0x607C in the 'possible object list in/out' of the two drive, and I don't understand where this object can be listed. So any ideas and suggestions regarding these two issues will be very, very welcome. If you need the source project, I am willing to send it.

Post by mondinmr on COL.IMap2 and HashTableFactory cause frequent Access Violation ^{CODESYS Forge talk (Post)}
Good morning, I’ve been using the Collection library for a long time, mostly with Stack, LinkedList, and List. From your examples I was able to manage the different factories, even for custom elements. Now I need a hashtable, but with this object I’m running into a lot of random access violations. If I append something inside FB_Init after constructing the hashtable, it crashes, even though the list was already created. If I only create the hashtable in FB_Init and append afterwards, it usually works. I don’t understand the meaning of the dispose call in this code: pSlave := ADR(slave); uSlave := TO_ULINT(pSlave); iKey := fKey.Create(uSlave); IF hash.CountKeys() = 0 THEN Service.logger.appendLog('Filling hashtable', 'HashManager', AdvLogType.AdvDebugMsg); ok := FALSE; ELSE eError := hash.ContainsKey(iKey, xResult => ok); END_IF IF NOT ok THEN pI := __NEW(UINT); iVal := fKey.Create(TO_ULINT(pI)); Service.logger.appendLog(CONCAT('New slave', TO_STRING(uSlave)), 'HashManager', AdvLogType.AdvDebugMsg); hash.AddKeyValuePair(iKey, iVal); appendNewSlave := pI; ELSE eError := hash.GetElementByKey(iKey, itfValue => iElem); xResult := __QUERYINTERFACE(iKey, itfIInstance); IF xResult THEN itfIInstance.Dispose(); END_IF IF eError <> COL.COLLECTION_ERROR.NO_ERROR THEN Service.logger.appendLog(CONCAT('ERROR ', TO_STRING(eError)), 'HashManager', AdvLogType.AdvCriticalMsg); appendNewSlave := nullptr; RETURN; END_IF __QUERYINTERFACE(iElem, iVal); {warning disable C0033} pI := TO___UXINT(iVal.UlintValue); {warning restore C0033} appendNewSlave := pI; END_IF Without the dispose call, every second cold reset crashes immediately when I try to access iVal, even if eError doesn’t report any error. With the dispose call, the cold reset issue disappears, but I get other problems: a) If I start the runtime using systemctl start codesyscontrol, it crashes at IF hash.CountKeys() = 0 THEN b) If I delete the files in PlcLogic and download again, it works and survives multiple cold resets. But as soon as I run systemctl restart codesyscontrol, everything gets corrupted again and it starts crashing at that point. FUNCTION_BLOCK SlaveMapCounter VAR hash : COL.IMap2; eError : COL.COLLECTION_ERROR; END_VAR In its FB_Init I create it: METHOD FB_Init: BOOL VAR_INPUT bInitRetains: BOOL; // TRUE: retain variables are initialized (reset warm / reset cold) bInCopyCode: BOOL; // TRUE: the instance will be copied to the copy code afterward (online change) END_VAR VAR hF : COL.HashTableFactory; END_VAR hash := hF.Create(256); In another FB I instantiate it statically: FUNCTION_BLOCK ABSTRACT AbstractServoEthercatController EXTENDS AbstractServoController VAR_STAT hashSlaves : SlaveMapCounter; END_VAR VAR field : REFERENCE TO ADVAbstractFieldUnitEthercatCia402; initCnt : REFERENCE TO UINT; END_VAR The append method is the one shown above, and I call it after the runtime has started. The accesses are performed by a single task, and in any case I’m working on an isolated single core. I’ve tried everything, moving the create, the instances, and all the rest several times, but nothing seems to work. I’d like to point out that these FBs are part of our own library, which is used in many applications.

Post by thommy54 on CODESYSControl_User cfg richtig konfigurieren ^{CODESYS Forge talk (Post)}
Hallo, nach Erwerb eines neueren Raspberry pi 4 (V1.5) musste ich zwangsläufig von Codesys 3.5.16 hochwechseln - ich habe auf 3.5.20.1 geupdated. Da schlugen mir plötzlich ne Menge Einschränkungen entgegen, deren Behebung einige Zeit dauerte. Eine davon ist, das ein SysFile.SysFileOpen nicht mehr funktioniert. Ich habe das Problem mit Einträgen in der /etc/CODESYSControl.cfg behoben: [SysFile] FilePath.1=/etc/, 3S.dat IecFilePath.1=/proc/, cpuinfo IecFilePath.2=/proc/, iomem PlaceholderFilePath.1=/sys/devices/w1_bus_master1, $OneWire$ PlcLogicPrefix=1 ; ; ---------------------- ; selbst eingefügt PlaceholderFilePath.2=/home/root, $my_home_root$ PlaceholderFilePath.3=/etc/init.d, $my_conf$ PlaceholderFilePath.4=/var/lib/mpd, $my_music$ PlaceholderFilePath.5=/root/Rasp_SPS_Filesystem, $my_Rasp$ Ob die Einträge sich etwas überlappen, kann mir gern jemand sagen, das ist aber nicht das Problem. Ich habe bei den vielen Versuchen, das Teil zum Laufen zu bringen, bemerkt, daß die Einträge auch ganz schnell mal verschwinden. Das ist ja auch so beschrieben, wenn die nächste Version kommt, sind meine Einträge weg. Da ich ähnliche Probleme mit dem Funktionieren von "SysProcessExecuteCommand2()" hatte, die ich ebenfalls mit Einträgen in die /etc/CODESYSControl.cfg hätte beheben können, habe ich gelesen, das man "private" Einträge lieber in die Datei /etc/CODESYSControl_User.cfg machen soll. Gesagt getan und "SysProcessExecuteCommand2()" lief: [SysProcess] Command=AllowAll Command.0=shutdown Aber auch irgendwo stand, das so ein Beteichner wie [SysFile] oder [SysProcess] nur einmal in den beiden Files /etc/CODESYSControl.cfg oder(!) /etc/CODESYSControl_User.cfg vorkommen darf. Das ist nun die eigentliche Frage! Ist das so ? Bei [SysProcess] ist das kein Problem, das gibt es in /etc/CODESYSControl.cfg nicht. Aber bei [SysFile] sieht das anders aus. Da sind 5 Zeilen schon in /etc/CODESYSControl.cfg drin. Würde ich diese in die User-Datei rüberschieben, könnte beim nächsten Update was fehlen oder, oder... Lasse ich es so wie es ist, sind meine Einträge beim Update weg - das sollte ja verhindert werden. Kann da jemand genaue Auskunft geben ?? Vielen Dank Thomas

Post by clarenced on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
I am looking for an example of how to run 2 applications on 1 device that would have global variables shared between the two apps. In this case what I am trying to do is to have the main program logic run as one application and then have the visualization run as a second application. I find this https://us.store.codesys.com/media/n98_media_assets/files/000013-F/0/Multiple%20Applications_en.pdf, that talks about exactly what I want to do, but I can't find the download. The main reason I want to do this is for download speed. Right now it takes at least a minute to download our application to the PLC. A simple program downloads to the PLC in a very short time, but add visualization and the download time gets much longer. If I could download the program separately from the visualization I think that a simple program change would take very little time to download. I have tried create a GVL in the POUs view. This partly works in that both applications can see the GVL, but they each create their own instance of it and the variables are not shared between the two apps. There are ideas of using OPCUA but this raises problems with licensing and having to move any variable that needs to be shared into the Symbol Configuration. This adds a lot of management to keep this up to date. Any ideas would be appreciated thanks.

Post by trusty-squire on SysProcessCreate2 on Linux runtime ^{CODESYS Forge talk (Post)}
Hi, I'm trying to launch a continuously running python script from Codesys and monitor the script status inside the Codesys runtime (running on a Linux enviroment). For now I'm testing with the below to emulate a continuously running Python script: #test.py i = 0 while True: i += 1 I'm able to successfully run the script using SysProcessExecuteCommand2 (I can see the Python process running in the task manager). However, this "freezes" the Codesys execution of the task - it sits on that command and will not continue until the Python script ends. I've proven this works by using the task monitor to kill the process, then Codesys continues on happily through the task. What I want to do is use SysProcessCreate2 to set up the Python script as a background task and monitor the process using SysProcessGetState. This always results in the error "ERR_OPERATION_DENIED". I know that I'm able to execute commands (as above), so my config should be correct. Is SysProcessCreate2 functional on a Linux environment? Is there something in the config file I'm missing? Here's my "working" code that uses SysProcessExecuteCommand2: VAR bTest : BOOL; sCommand : STRING := '/usr/bin/python3 /var/opt/codesys/PlcLogic/Application/test.py'; refCommand : REFERENCE TO STRING REF= sCommand; sOutput : STRING; refOutput : REFERENCE TO STRING REF= sOutput; result : RTS_IEC_RESULT; END_VAR IF bTest THEN SysProcessExecuteCommand2( pszCommand:= refCommand, pszStdOut:= refOutput, udiStdOutLen:= SIZEOF(sOutput), pResult:= ADR(result) ); bTest:= FALSE; END_IF And here's the code that always results in the ERR_OPERATION_DENIED error: VAR bTest : BOOL; sApp : STRING := '/usr/bin/python3'; sCommand : STRING := '/var/opt/codesys/PlcLogic/Application/test.py'; refApp : REFERENCE TO STRING REF= sApp; refCommand : REFERENCE TO STRING REF= sCommand; hResult : SysProcess.RTS_IEC_RESULT; hHandle : SysProcess.RTS_IEC_HANDLE; END_VAR IF bTest THEN hHandle := SysProcessCreate2( pszApplication:= refApp, pszCommandLine:= refCommand, ulFlags:=SYSPROCESS_CREATEFLAG_HIDDEN, pResult:= ADR(hResult) ); bTest:= FALSE; END_IF Here's the relevant section from the config file at /etc/codesyscontrol/CODESYSControl.cfg: [SysProcess] Command=AllowAll Appreciate any support or ideas.

Post by jami on Reading multiple lines from csv file ^{CODESYS Forge talk (Post)}
Hello, i am trying to read multiple lines from csv file with caa file library and oscat. I have wrote 7 lines in the csv with separation '$R$L'. In my "extracting values" part I check line feeds and chars. After that I convert my buffer to string with oscat but I'm only able to read the first line from the csv. No matter if I even change start position where I start converting the buffer, I only get the first line. Here's my code for the reading and extracting value parts: 4: (*Reading the file*) fileread.hFile := filehandle; fileread.pBuffer := ADR(buffer); filesize1:=SIZEOF (buffer); fileread.szbuffer:=filesize1; fileread.udiTimeOut := 100000; fileread(xExecute := TRUE); IF fileRead.xDone THEN iFilesize:=TO_INT(fileread.szSize); writestate:=3; fileRead.xExecute := FALSE; END_IF 5: (*Extracting values*) //here i check the number of line feeds and chars. It works WHILE i < ifilesize DO c:=buffer[i]; IF c= 10 THEN IF lineindex<=99 THEN lineIndex := lineIndex + 1; END_IF ELSIF c <> 13 THEN IF charIndex <= 1000 THEN charIndex := charIndex + 1; END_IF END_IF i := i + 1; END_WHILE // Here i convert the buffer to string and transfer it to filelines:ARRAY[0..99] of string[254]. trig(CLK:=BUTTON); IF trig.Q THEN fileLines[i2]:=oscat_basic.BUFFER_TO_STRING(PT:=ADR(buffer), Size:=TO_UINT(fileread.szBuffer), start:=TO_UINT(bufferStart), stop:=TO_UINT(filesize1)); i2:=i2+1; bufferstart:=bufferstart+80; END_IF If anyone has idea how to read multiple lines, it would be nice. Even if you have example codes that work, that would help a lot.

Post by tk096 on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge talk (Post)}
Hi, under this circumstances the performance of a Raspberry Pi 4 should be sufficient to run a Softmotion robotics application. A closer look at the project would be required. Maybe you could contact the codesys support? Usually it is recommended to run the planning task cyclically every 2ms with task priority of 0 on a dedicated core. In the task configuration you can have a look at the average and maximum execution time of the planning task. You could use the function block SMC_TuneCPKernel (https://content.helpme-codesys.com/en/libs/SM3_Robotics/Current/SM3_Robotics/POUs/AdministrativeConfiguration/Computation/SMC_TuneCPKernel.html) to define suitable values for the parameters 'fSyncBufferDuration' and 'fPlanningInterval'. However, as previously mentioned, the performance of a Raspberry Pi 4 with realtime patch should be sufficient. The 'fPlanningInterval' parameter specifies the maximum planning step width in seconds. The cycle time of the planning task should not permanently exceed this value. A higher value reduces the computational effort, but can lead to a violation or no full utilization of the set limit values for velocity, acceleration and jerk. From a starting value of 0.016 seconds, the value should be increased gradually until the performance is acceptable. The parameter 'fSyncBufferDuration' specifies the size (in seconds) of the buffer between the planning and fieldbus task. The cycle time of the planning task must not exceed this value at peak times (this will lead to the error SMC_CP_QUEUE_UNDERRUN). A higher value can compensate for peaks in the cycle time of the planning task. At the same time, however, this also increases the latency for executing interrupts and aborting movements.

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 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.

Post by rkohser on Scripted Git clone / checkout being blocked by "Project Environment" popup ^{CODESYS Forge talk (Post)}
Hi, I am trying to build a CI/CD pipeline around our codesys projects. The only entry point if the git url and branch, as we do not put our project file under source control, so we needed to find a way to git clone from the python scripting engine. This is currently how we do this : system.commands["Git", "Clone"].execute( "ProjectLocation=" + project_dir, "ProjectName=" + project_file_name, "RemoteUrl=" + project_git_remote_url, "GitProjectStoragePath=" + project_git_local_dir, ) system.commands["Git", "Checkout", "Branch"].execute( "PrimaryProjectHandle=0", "BranchName=origin/" + project_git_branch ) This works fine, except that, depending on the environment and the project, the "Project Environment" popup gets displayed to suggest for some updates, and waits for a user interaction, even with the "--noUI" flag injected as parameter. I investigated the VersionUpdateFlags, but the problem is that the git clone is an atomic operation that clones and directly opens the generated project without the possibility to inject any updateFlags argument (only used in the ScripProjects.open() function. I also tried to simulate some keyboard events acknowledge the window from script but I did not find the right location for the SendKeys statement, I think before the git clone call is too early and after is too late. So I am wondering if there would be some other way to do that. Is there some more proper scripting api for the git add on ? Is there a global configuration of the VersionUpdateFlags that would allow the popup to be disabled outside from any project context ? Is there some way to automatically acknowledge this kind of messages in a "--noUI" mode ? What do you suggest ? Thanks for your help, Roland Edit : I managed to solve my problem by following these steps in my pipeline : - create a template of a project and opt file preconfigured not to open the popup - open this project - initialize an empty git repo - add the remote, fetch and checkout the needed branch -> no popup is displayed, hourra Edit2 : The initial question was raised on a CODESYS V3.5 SP18 Patch 2 profile. Since CODESYS 3.5.19.30 a scripting API is available for Codesys Git that allows cloning a project with the support of VersionUpdateFlags https://content.helpme-codesys.com/en/CODESYS%20Git/_git_using_scripting.html

Post by dandyk on Dynamic Images ^{CODESYS Forge talk (Post)}
Hello, I have very similar problem, but it seems that your solution does not work for me. I am using TwinCAT XAE Shell v3.1.4024.55 and TwinCAT Runtime. Sorry for writing here on codesys forge, but since I found the only relevant topic here and since TwinCAT is almost the same with CODESYS in many applications, I chose to write here. I simply need to dynamically update image in visualization based on camera trigger (I am doing a machine vision application). Camera triggers an image, my program processes it (applies thresholding, draws contours etc...) and saves the processed image in the runtime location (the same one you were mentioning). This was done successfully. I need to make it work at runtime, while the program is executing and I need to refresh the image in the visualization each time camera triggers a new image and program processes it. When I create image element in the visualization and define the bitmap ID variable as STRING which contains the image ID defined in the image pool, then it displays the image in the image pool, but does not work at runtime, while the program is executing. I also used the Bitmap Version. I declared it in Global variable list as integer with initial value of 0 and wrote the variable in the bitmap version in the image element in visualization. Each time new image is saved to the runtime location, I wrote a program to increment Bitmap Version by 1. It increments and the image does not update in the visualization, unfortunately. I think that bitmap version is working correctly and deletes the cached image as it is supposed to, but the Image Pool does not update the image ID with the new image... the path to the image is always the same... only the actual image changes with the same file name. Image Pool is not dynamic and cannot refresh the image in the path to the actual one at runtime. How can I refresh the image ID in the image pool at runtime? Bitmap version only deletes cached image and reloads the image from the image ID, but the image ID has the same image, because image pool won't update at runtime. Do you know any solution to this problem?

Post by drbuzz on Communication Error (#0) for IFM controller ^{CODESYS Forge talk (Post)}
Hi Folks, Every time I use an IFM controller I always seem to run into a problem connecting to it. I get the Communications Error (#0). So I thought I would share some tips and tricks. Once the CANfox Cable (EC2112) cable driver is installed, you can use the yellow app in the sys tray to blink the lights on the cable. Confirm the cable works in the IFM maintenance software by connecting to the controller and reading the information on it. Make sure to download an OS into the controller (the light will go from a fast blink to solid green). In Codesys V2.3, the communication settings for the CR0401 is 250kBaud by default and Node ID 127. What got me, was I needed to reboot the computer after the cable driver install. Also if your application has canbus settings in it which are changed from default, after the controller is power cycled, the new Node ID and Baud will be in effect. I made a handy guide because too much time has been wasted on this. Programming IFM CR0401 Serial/Can Programming Cable • Connect IFM EC2112 CanFox programming cable with connector adapter. • Make sure cable is linked to VM (if using VM). • Install drivers for cable if not installed. o Download from IFM EC2112 site. https://www.ifm.com/ca/en/product/EC2112 • Once Installed, reboot computer. • In system tray, there should be a yellow icon that you can open and check on programming cable. Select the cable in the list and flash the lights to confirm it is working. Maintenance Software • Install IFM Maintenance Tool Software. o Download from IFM Site. https://www.ifm.com/ca/en/download/eco100_MaintenanceTool • Open IFM Maintenance software • Select Basic System • Select CAN cable • It will tell you if you don’t have a cable connected. • Use Wizard if needed. • Read Channel Parameter on the Settings page, or get Identity in the System Information > Identity. • Default Node is 127 on a new unit. Baud is 250kBaud (bits/sec) • Controller information should populate. • Controller green light should be blinking at 5hz (meaning OK but no OS, just bootloader). • Click Software > Load. • Open the OS file. Should match Codesys version selection (for CR0401 this is version 3). o Download OS file from IFM Website. https://www.ifm.com/ca/en/product/CR0401 o It is located at the top of the download under “software for CR0401”. o Select the file and load it… this will take a minute. • Once completed the unit should now have a solid green light o Solid green means the controller has an OS but no application is running. Codesys V2.3 Application • Codesys needs to be downloaded and installed from the IFM website as it has the IFM libraries and license to use the software. o Download from the IFM CR0401 page. o https://www.ifm.com/ca/en/product/CR0401 • Create new application with the correct IFM controller or Open Codesys application. • Keep in mind that the PLC Configuration on the Resources tab can be changed for the CAN communication interface… so changes to node and baud will take effect after the first download and reboot of the controller. • Go to “Online” in the top menu and change “Communication Parameters” o The Local dropdown shows the last configuration used. All other interfaces will show below it and need to be updated when changed or used. o Confirm Node ID is 127 for the first download.  The NodeID will change to whatever the program has after (in my case 125).  Node Send Offset should be default at 1536  Node Recv Offset should be default at 1408  Can bus Baudrate should be 250 kbaud.  Yes to Motorola Byte Order  Block Transfer should be false and note used (60 is default setting).  Can Card Driver should match the systray item which is Sie_USB. • If the system populated the other one, just update and relay the communication parameters. The software will usually bring up the available cable and driver. • Go to “Online” and Login to download. o Press Yes to Download Application. I hope this helps!

Post by smeitink on Timeout Error in Modbus Communication with WAGO PFC200 and iEM2050 Meter using 750-652 Module ^{CODESYS Forge talk (Post)}
Hi all, I'm looking for help with an issue I've come across while trying to facilitate Modbus communication between a WAGO PFC200 PLC using a 750-652 communication module and an iEM2050 Series Single Phase Energy Meter. I believe to have everything wired and setup correcty, but I keep running into a "Error time out" message, and by now I don't really know what else to try. My setup is as follows: A PFC200 Wago PLC, which has 2 750-652 Serial Interfaces extension modules connected to its field bus. I'm using one of these to talk to a Schneider iEM2050 - kWh-meter over modbus. I have connected terminal 23 (A) of the iEM2050 to connector 6 (A) on the 750-652. I have connected terminal 24 (B) of the iEM2050 to connector 2 (B) of the 750-652. I'm using 200mm of twisted together wires to connected them both, and I have placed a 120 ohm resistor between A and B at both ends. I've attached relevant pinout images to this post. I then wrote a simple program that configures the Mobus port, as per the datasheet of the iEM2050. You can find an image of the relavent page attached to this post too. This is my program: PROGRAM PLC_PRG VAR Master: FbMbMasterSerial; xIsConnected: BOOL; xError: BOOL; iIndex: INT := 1; xTrigger: BOOL; utQuery : typMbQuery := ( bUnitId := 1, // The Modbus unit or slave address bFunctionCode := 4, // Function code for reading input registers uiReadAddress := 1829, // adress for the Power on off counter uiReadQuantity := 1 // Quantity of registers to read ); iStep: INT; oStatusModbus: WagoSysErrorBase.FbResult; utResponseModbus: typMbResponse; xConnect: BOOL := FALSE; delayTimer: TON; END_VAR Master( xConnect:= xConnect, I_Port:= _750_652_24_1, udiBaudrate:= 9600, usiDataBits:= 8, eParity:= WagoTypesCom.eTTYParity.Even, eStopBits:= WagoTypesCom.eTTYStopBits.One, eHandshake:= WagoTypesCom.eTTYHandshake.None, ePhysical:= WagoTypesCom.eTTYPhysicalLayer.RS485_HalfDuplex, xIsConnected=> xIsConnected, xError=> xError, oStatus=> oStatusModbus, eFrameType:= WagoAppPlcModbus.eMbFrameType.RTU, tTimeOut:= T#5S, utQuery:= utQuery, xTrigger:= xTrigger, utResponse:= utResponseModbus); delayTimer(IN := TRUE, PT := T#3S); // Use the Q output of the timer to set xConnect after the delay IF delayTimer.Q THEN xConnect := TRUE; END_IF CASE iStep OF 0: //Wacht totdat de master de poort geopend heeft IF xIsConnected THEN iStep := 1; END_IF 1: //Stuur request naar de slave xTrigger := TRUE; iStep := 2; 2: //Wacht totdat de master klaar is met het afhandelen van de request IF NOT xTrigger THEN iStep := 3; END_IF END_CASE The TON delay before opening the port is due to a an error I encountered when opening it straight away. This seems to be a bug, as described here. However, the TON solved that particular issue. I tried reading multiple registers, but like I said, I still always end up with the "Error time out". What else can I test or try at this point?

Dear all, My python script can read a Codesys project and save in file the different POU, but the problem is that I don't able to read the project info from the obj list.
