Post by bertcom on STRING conversions to DWORD ^{CODESYS Forge talk (Post)}
Good afternoon. I want to communicate with a Domino Industrial Printer using its Codenet protocol. The printer wants a series of Hexadecimal characters with no spaces or '00' characters. Because of that i chose the option to make the prefix and subfix for my code in a string. I have variable data in another string. With a complete program of a lot of CONCAT functions i eventually get the format of code that the printer accepts ( tested it with the hercules tool). Hercules String : 1B4F513030311B7532626C61636B04 The problem is : Codesys adds automatically 'code' to the code to show it is a string. Codesys string : '1B4F513030311B7532626C61636B04' The printer does not understand this. My idea is to convert the string datatype to an LWORD. I have no idea how to do this. I random types in STRING_TO_DWORD, as return i get 0. That didn't worked. Also on internet the explenations around string converting in codesys are very limited. If there in anyone who can explain me how to do it, i would appreciate it a lot ! Thank you!

Post by pikebuster on Help for a newbie ^{CODESYS Forge talk (Post)}
Can somebody help me with this? I have problem with the button! This task must be solved using Sequential Function Chart (SFC), IEC 61131-3. TASK Create an SFC program to control a traffic light at an intersection. Description: You will program a traffic light that has three phases: Green, Yellow, and Red. The traffic light must follow these rules: Green light is on for 10 seconds. Yellow light is on for 3 seconds. Red light is on for 10 seconds. If the pedestrian button is pressed, the system must keep the red light on for 20 seconds during the next cycle. After the pedestrian has “crossed,” the system should return to its normal cycle. Basic Steps: Initialization: Start by setting the traffic light to Red. Green Phase: After 10 seconds, switch to Green. Yellow Phase: After 10 seconds in the Green phase, switch to Yellow. Red Phase: After 3 seconds in the Yellow phase, switch back to Red. Loop: Repeat the cycle. Use, for example, lamp symbols in the visualization module to simulate the traffic light. You may also add a simple pedestrian light if desired.

Post by pistola on C0357: "GetNextClient" is obsolete, use VisuUtils instead ^{CODESYS Forge talk (Post)}
I'm having some troubles with this same issue and I'm wondering if someone can help me out. On a settings visual I allow the operator to enter some values however if they activate the page change button it will change the change with the Numpad dialog open. Since I'm using Visuelems.CURRENTVISU to change the pages I came across this code noted below for determining if the Numpad dialog was active. This code worked great however now in 3.5.19 it's now obsolete. I've tried following the directions in the attached program above however I can't see to get it to work in my program. Can anyone provide some help to determine if a dialog is open? FUNCTION Check_Dialog_Open : Bool VAR_INPUT sDialogName : STRING; // Input variable for the name of the dialog END_VAR VAR pstClientData : POINTER TO VisuElems.VisuStructClientData; // Pointer to the client data structure itfDialogManager : VisuElems.IDialogManager; // Interface for the dialog manager itfMyDialog : VisuElems.IVisualisationDialog; // Interface for the specific visualisation dialog END_VAR // Begin the iteration over the client manager VisuElems.g_ClientManager.BeginIteration(); // Loop through each client until no more clients are found WHILE (pstClientData := VisuElems.VisuElemBase.g_ClientManager.GetNextClient()) <> 0 DO // Get the dialog manager interface itfDialogManager := VisuElems.g_VisuManager.GetDialogManager(); // Get the specific dialog interface using the dialog name itfMyDialog := itfDialogManager.GetDialog(sDialogName); // Check if the dialog is open for the current client Check_Dialog_Open := VisuDialogs.VisuDlgUtil_IsDialogOpen(itfMyDialog, pstClientData, itfDialogManager); // If the dialog is open, exit the loop IF Check_Dialog_Open THEN EXIT; END_IF END_WHILE

Post by kuegerls on Programmatically clearing or syncing Data Source Manager cache? ^{CODESYS Forge talk (Post)}
Hi everyone, is there a way to programmatically clear the cache of the Data Source Manager in CODESYS so that variable values are re-synchronized from the OPC UA server (Symbol Configuration with OPCUA features)? Alternatively, is it possible to trigger a manual synchronization of data source variables from within the application code at runtime? Here’s the situation: A variable is first written by the OPC UA client to the server in one state of a state machine and changes to another state – so the initial communication works. Later, the server changes the variable value, but the client does not receive or reflect the updated value, unless the variable is actively written again. I’m looking for a way to force the client (data source manager) to re-read or refresh the variable state from the server, possibly by clearing the internal cache or triggering a sync. Any ideas or suggestions would be greatly appreciated! Thanks!

Post by shaunvdm on Canbus Slave SDO Read from Object ^{CODESYS Forge talk (Post)}
Busy testing a solution to use Canbus Slave to replace a physical device and convert to Ethercat device but keep the Canbus Master in place. Master needs to Read SDO object 5FA2. In the Master PLC if i send the SDO with 8 bytes in message IE: 60B 40 A2 5F 00 00 00 00 00 i get my expected 58B 43 A2 5F 00 00 68 36 02 containing data back. Problem is if we issue a 4 byte command can send 60B 40 A2 5F. Surely the canbus slave should respond with a 58B 43 A2 5F 00 00 68 36 02 but it comes back as 80 A2 5F 00 00 00 00 08 - meaning this OBJECT does not exist. Is there a setting in the canbus slave driver for Canbus to allow the 4 byte command to read the SDO OBJECTS ?

Post by pouyavakili on Execute Codesys Tests with python ^{CODESYS Forge talk (Post)}
Thank you for your input! What I'm ultimately trying to achieve is automated test execution as part of a CI/CD pipeline (e.g. in GitLab or Azure DevOps). For this, I need to: Open a CODESYS project via script Build the project Run the Test Manager tests from a .TestRepository.xml Collect test results (e.g., pass/fail + a report) Exit with a proper return code (for pipeline success/failure) To integrate this into automation, I’m using the CODESYS scripting engine via Python (headless), but the issue is that the get_testmanager() function isn't available on the project object — even though Test Manager is installed, licensed, and works interactively in the IDE. Are you suggesting that I should: Use the Test Manager GUI to script the logic with its internal scripting language? Or is there a way to launch the Test Manager in headless/scripted mode, while still being able to control things via Python? If there's a supported way to automate tests with the Test Manager using scripting, especially from pipelines or headless environments, I’d really appreciate any pointers or example workflows. Thanks again!

Post by gunstr on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
We have been using the Codesys Control for Rasberry Pi for several years in many installations without any major issues. But during summer the problem mentioned above has blocked further deliveries. We have made some minor upgrades to the application but I do not really see why that should have any impact. HW is Raspberry Pi 4B, 2GB OS is Booworm Lite Codesys control is version 4.15 (have just installed a few systems lately with this version) The system boots OK but after exactly 30 seconds Codesys is shut down and becomes unreachable. We have tested several different combinations: Upgrade of the Codeys Control to 4.16 Loading different Codesys applications Changing to 4GB version of the Raspberry Pi One of the test applications together with the 4GB HW seems to be stable, but all other combinations fails. Any suggestion what we can do to resolve is appreciated - this is a real business blocker now. Rgds

Post by alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
Sorry for the question, but I'm not completely getting the idea here, could you be more specific, maybe give an example? I'm now in a state where I don't have a softcontainer on my license server anymore (even after reinstalling from the Codesys-IDE). I tried reaching the webserver of Codemeter but when I do that I get redirected to http://"IP":22352 This is not reachable, afterwards I installed lynx on my Debian machine (command line only). From here I could reach the webserver and toggle the network server setting, but unfortunately this did not help. I also tried to changed the remote read setting to 1 (in the Server.ini file). But after a Codemeter reboot this is overwritten to 0. I have the feeling that it should be much easier to get a license to work, am I missing some checkbox somewhere? Is there a tutorial (or manual) that explains the licensing sequence step by step, because I'm pretty stuck.

I'm trying to evaluate how my infrastructure will interact with Codesys on a Raspberry Pi 4, so I'm trying to demo running it before purchasing licenses. I was going through the Codesys tutorial here, and it never shows the tab as grey, so I do not know how to proceed. Let me know if I can get any additional information that can help. This could be related to an Info message that's sent when connecting- [INFORMATION] Connected successfully!

Post by dtamm on How to read string from CharBufferPtr? ^{CODESYS Forge talk (Post)}
I am trying to implement a mechanism to send alarm SMS. For this, I have created an Alarm Class with a Notification Action which calls a POU. This POU implements IAlarmNotifiable making it selectable in the Alarm Class configuration. IAlarmNotifiable has an Execute method which is called by the alarm class. Now, I want to extract the alarm message of the triggered alarm. The Execute method comes with a VAR_INPUT itfAlarm: AlarmManager.IAlarm which supplies a method called GetMessage. The help text says: Returns the message text, that has been configured for the alarm. The result is a pointer to the buffer, where the message text is stored The type of the result is CharBufferPtr, and at some place I read that it can be interpreted as a pointer to string. But I cannot manage to extract the alarm message, all I get are numbers. I have tried the following: psAlarmText := itfAlarm.GetMessage(__SYSTEM.TYPE_CLASS.TYPE_STRING)^; sAlarmText := TO_STRING( itfAlarm.GetMessage(__SYSTEM.TYPE_CLASS.TYPE_STRING)^ ); So how do I get access to the alarm message as clear text? (In this case, "Larm 1")

Probably the information model from 15/09/2021 is missing in the information model repository. The error message does not make sense to me. Should it not be “Probably the information model from 15/12/2023 is missing in the information model repository”? Anyway, both versions are available in the repository. How can I solve this?

I am at the stage where I wanted to use the Festo HMI screen, and have added a RemoteTargetVisu object to my application. After adding this object, I am no longer able to log in to the PLC as I get an Unresolved Reference warning for 'USERMGRUSERGETPROPERTY' towards the end of the download process. I was able to find this post (https://forge.codesys.com/forge/talk/Visualization/thread/fc686a6cb2/) where the two possible solutions are to "set the placeholder to emtpy" or update the runtime. Problem is, I don't know how to do either of these things, as I'm still very green in Codesys land. I'd be happy to update the Festo PLC runtime, as that seems like the better option, but have not had any luck in finding a tutorial for this online. If anyone could point me in the right direction I'd appreciate it.

Post by phoward131 on Alarm State Icon ^{CODESYS Forge talk (Post)}
I am trying to create an icon on an overview screen that depicts if an alarm group has active alarms, active acknowledged alarms, or inactive unacknowledged alarms (waiting for confirmation). I've attempted to set up Notification Actions in the Alarm Class to set variables based on state changes but have been unable to find a clean and effective way to do this. Because an action on any alarm will trigger the variable to be set as instructed, I'm struggling to find a way to configure it for what I need (ie if two alarms activate, then one deactivates, the variable for indicating an alarm is active would be cleared after the single deactivation). I've been pointed toward the Alarm Manager example project but I'm finding it too complicated to understand how to implement it in my own project. Has anyone come up with another good way to indicate the states of alarms or a simpler usage of the Alarm Manager functions?

Post by k2saki on CNC / G01 Speed is very slow (or go-stop motion) in Continuous short segment . ^{CODESYS Forge talk (Post)}
I'm using CAD/CAM that outputs GCode with G01 many short segments from NURBS Curve, only X-Y axis. But CODESYS CNC motion seems much slower ( or stop-go motion ) in simulation mode than F-Value (I checked value from SMC_Interpolator - dVel ). In GCode G01, F value is F500, but movement is very slow, actual speed (dVel) is between 0 to 30 back and forth. I think very old CNC can move like that, but nowadays, a lot of CNC can move smoothly to process free curve ( somethimes option switch ) I tried to use G51 Dxx but I got the same result. My questions are 1) How do I improve CODESYS CNC motion in this case ? 2) How can I graph the sampling from dVel of SMC_Interpolate in CODESYS?

Post by caprez95 on Deleting the trend recording history ^{CODESYS Forge talk (Post)}
Hallo Ich möchte eine laufende Trendaufzeichnung stoppen, den Inhalt löschen und Trend-Diagramm auf 0 zurücksetzen. Laut Codesys soll das mit dem folgenden Code möglich sein: You can insert an input element in the visualization which the operator can use to delete the previous value recording in the trend visualization at runtime. The curve displayed until then is removed and the display starts over. In the application (example: in the program PLC_PRG), implement the following code: itfTrendRecording : ITrendRecording; itfTrendStorageWriter : ITrendStorageWriter; itfTrendStorageWriter3 : ITrendStorageWriter3; sTrendRecordingName : STRING := 'TrendRecording'; itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); xClearHistoryTrend: BOOL; IF xClearHistoryTrend THEN itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); IF itfTrendRecording <> 0 THEN itfTrendStorageWriter := itfTrendRecording.GetTrendStorageWriter(); IF __QUERYINTERFACE(itfTrendStorageWriter, itfTrendStorageWriter3) THEN itfTrendStorageWriter3.ClearHistory(); END_IF END_IF In the visualization of the trend recording, add a button for deleting the previous curve. Configure its Toggle property with the variable PLC_PRG.xClearHistoryTrend. ⇒ When xClearHistoryTrend is set to TRUE, the previously recorded curve is deleted. The recording immediately starts again. Dies löscht auch die Daten vom Trend, aber das Diagramm wird nicht auf 0 zurückgesetzt, sondern läuft einfach da weiter wo man gestoppt hat. Braucht es für den Diagramm-Reset noch einen zusätzlichen Befehl? Gruss

Post by john-robinson on Limiting Memory Access of an Array to Within its Bounds ^{CODESYS Forge talk (Post)}
Recently we had an issue regarding some simple code to calculate a rolling average. The code indexes from zero to 199 to properly store the current input into a circular buffer which then allows us to calculate a rolling average: VAR input_5s : REAL; outs_arr : ARRAY[0..199] OF REAL; i : USINT := 0; END_VAR ___ //this code runs every five seconds, calculating a rolling average outs_arr[i] := input_5s; i := i + 1; output := OSCAT_BASIC.ARRAY_AVG(ADR(outs_arr), SIZEOF(outs_arr)); IF i >= SIZEOF(outs_arr) THEN i := 0; END_IF There is a simple bug in this code where the index will be set to 0 when it has surpassed the length of the array in bytes (800 in this case) rather than larger than the number of reals in the array (200). The solution here is simple, replacing i >= SIZEOF(outs_arr) with i >= SIZEOF(outs_arr)/SIZEOF(outs_arr[0]). In this example when the index increased to 201 and the line outs_arr[201] := input_5s was called, codesys arbitrarily wrote to the address in memory that is where outs_arr[201] would be if the array was that long. I would like to find a way to wrap the codesys array inside of a wrapper class that checks if an input is within the bounds of an array before writing to that value. I know how I would implement that for a specific array, I could create a method or class that takes an input of an array of variable length, ie. ARRAY[*] OF REAL, but I don't know how to make this for any data type. I am wondering if anyone has ever done anything similar to this, or has any better suggestions to ensure that none of the programmers on this application accidentally create code that can arbitrarily write to other locations in memory.
