Post by adamrobotic on llcallback() iec exception caught cmpid=0x00000002, eventid=0x00010008 ^{CODESYS Forge talk (Post)}
Hi All, Recently I have been experiencing a issue in CodeSys SP16 Patch 3, with a exception which comes up after I have made several online changes. callcallback() iec exception caught cmpid=0x00000002, eventid=0x00010008, after I experience this fault then I receive a error message for any subsequent online change "online change failed, no task gap within 10000ms". To recover either the controller needs a orgin reset, which will allow online edits thereafter until falling back into the loop. I am using a TURCK TX707 product which is controlling robot trajectory, We have hard coded the coordinate data rather than using persistence variables so hence the need to do online changes consistently. I have read on the forum other people have experienced similar issue with the online task gap, but I have no task which have same priority and also monitored the CPU usage and have not seen it go above 13%. Anyones help would be much appreciated, thankyou.

Post by danieldiaz on Problem with FB execution ^{CODESYS Forge talk (Post)}
Hello everyone, I've been working on a system which needs an error function, with this purpose I've created a FB programmed in LD, after debugging I run the simulation. It seems that the variable linked to a coil doesn't change the value when the contacts are associated to input variables. When I use internal variables the logic works properly. I don't know if the problem is related to the variables definition or with the logic program. As you can see in the image, I1 and I2 are variables declared on the FB, the rest are input variables. If I force the eStop and Reset signals to TRUE the coil value should change, but it doesn't. However in the second network if I1 is TRUE the coil change to TRUE as it has to be. To sum up, my doubt is why that coil doesn't change its value? I would like someone to shed a light on this. Thanks!

Post by joel214 on OPC-UA / Unterschied Symbolkonfiguration, IEC-Symbolveröffentlichung und Informationsmodell ^{CODESYS Forge talk (Post)}
Hallo liebe Community, im Rahmen einer Studienarbeit gilt es ein OPC-UA-Informationsmodell in eine existierende CODESYS-Steuerung zu implementieren. Dabei sind wir auf die Frage gestoßen welcher Unterschied zwischen den folgenden Objekten besteht: - Symbolkonfiguration (veraltet?) - IEC-Symbolveröffentlichung - Veröffentlichung über zuvor erstelltes Informationsmodell In unserem Verständnis erfüllen alle Objekte die Gleiche Aufgabe nur mit unterschiedlicher Vorgehensweise und Darstellung im OPC-UA-Server. Während durch die Symbolkonfiguration die Variablen und Instanzen über lange und verschachtelte Pfade abgelegt werden, wird durch die IEC-Symbolveröffentlichung ein Ordner im Pfad der Objekte erstellt. Dort sind die Variablen und Instanzen anschließend zu finden. Bei der Verwendung von Informationsmodellen hingegen, werden die Instanzen direkt unter den Objekten abgelegt. Für welchen Anwendungsfall ist welche Vorgehensweise am besten? Vielen Dank vorab und viele Grüße Joel

Post by ferrim on IEC 61499 ^{CODESYS Forge talk (Post)}
IEC 61499 is probably something more complex than what you have correctly said so the prospects are interesting but we cannot ignore that it came out almost 20 years ago and has not won many hearts. I started to explore this world with a PLCnext controller because I love these devices based on RT Linux and Codesys is somehow usable with them but I have made little progress and I feel like inside a nutshell in the middle of the sea ;-) Gary's voluminous and precious book is always on my desk...

Post by jf-fischer on PFC200 als Protokollumsetzer ^{CODESYS Forge talk (Post)}
Hallo, ich möchte IEC 104 Protokolldaten von einem Gerät über Ethernet empfangen, in ein Modbus-TCP Protokoll umwandeln und weiter geben (lesen und schreiben) an andere Modbus Geräte. Dies soll auch in die andere Richtung funktionieren, so dass daten aus dem Modbus Register vom IEC Gerät ausgelesen werden können. die Umwandlung soll eine pfc200 sps von wago durchführen. am Ende sollen die Daten in einer Webansicht visualisiert werden. das Programm der wago möchte ich in codesys 3.5V programmieren. Kann mir jemand helfen, meine Erfahrung mit Codesys ist leider bis jetzt nur sehr grundlegend.

Post by fless on Warning C0564 when compiling CNC project with variables program ^{CODESYS Forge talk (Post)}
Hello, we are porting a CNC project from codesys 3.5.16 to codesys 3.5.19. The project has lots of CNC programs with variables. now we get hundreds of messages like this. [WARNING] CNC Test SP19: TestCNC SPS: PLC Logic: Application: C0564: A reference to uninitialized variable varCNC is used for initialization of TestCNC_D. Accessing the uninitialized variable may result in unexpected behavior. The objects program_name_D are implicit generated by codesys. I see no way to generated them after the variables. Is there a way to correct the initialization order? We know how to suppress this warning. But we need a clean solution as the warning already saved us in a other nonCNC project. Attached a small demo of the problem.

Post by sachem on Problem retain values Weidmuller UC20-WL2000 ^{CODESYS Forge talk (Post)}
Good afternoon. I am working with a weidmuller uc20-wl2000 controller, using a codesys license. We made a ladder code to control a process, and it works well, but we want some variables to remain stored even when the controller is turned off. We tried to use retain variables, but at the time of loading the program, when we went offline from the controller, the program was deleted, it did not remain in the controller, and in the same way if we turned off the controller. In addition to this, when we tried to program it again, the program would not stay loaded and began to present errors with the opc-ua communication. What could be causing this problem? How can we maintain the values of the variables without damaging the program or affecting the controller? thank you

Post by westcountryewe on Persistence Variables missing and DO NOT retain from Persistence Channel when using Boot Application ^{CODESYS Forge talk (Post)}
We've been experiencing an issue through SP18, SP19 and now SP20 where the Persistence Variables do not retain if we upload our program via a Boot Application. If we use the exact same program, and perform a Direct Upload via the Laptop and Ethernet connection, the Persistence Variables work exactly as expected. I have submitted 2 bug support tickets but I haven't had a response back from Codesys. Has anybody experienced the same issues and discovered a workaround? We have a requirement to utilise the Boot Application method because of logistical restrictions of being able to get out to every site, so at the moment it's a bit restriction.

Post by ofey on Symbol configuration / GVL ^{CODESYS Forge talk (Post)}
Hi! I have som variables that I communicate to a Modbus Master. These variables are declared in a "Global Variable List" where I have assigned them memory addresses. To organize this mapping I want to make a MODBUS list where I show all the variable names together with the memory address. Is there an easy way to export this list from CODESYS? Either through script or some export function maybe?

Post by timvh on Management of a PLC network from a remote station ^{CODESYS Forge talk (Post)}
Maybe the CODESYS HMI is a good solution. https://store.codesys.com/en/codesys-hmi-sl-bundle.html Run this on the remote main control station. In the HMI application you can add the data source manager and to this manager you can add Data sources. A data source has a reference to the PLC you want to connect to and can get access to the variables of the PLC application. You can then use these variables in the visualization of the HMI application.

Post by pietrobalint on Retain / Persistent Variables in Codesys for Raspberry Pi ^{CODESYS Forge talk (Post)}
Hi micik, I am not sure I am using well the code, because I checked the directory and there is no retains.ret file. Now I deleted the code from my project and the values are still works as persistant variables after ssh reboot it seems to me they retain as their previous value. So I am a bit confused, maybe 4.12.0.0 Raspberry Pi SL solved the persitent variable problem...

hello edwin i have did the same and i could connect the opc-ua server but i dont see anything in the resources tree, in the application i linked my variables to the symbol configuration but i dont see that in the uaexpert. if i use the same application with a non linux system i can get those variables values and see the complete tree structure. What could be the problem ?

Post by shooxplc on How to call the same program from library and get the vars updated. ^{CODESYS Forge talk (Post)}
Hi, I am writing to you today because I would like to create a library that would contain a program with its various subprograms, in my example "PLC_PRG" with "a", "aa", "aaa". But once the library is created as shown below: I would like to be able to drag and drop my folder as many times as I want (let's say I manage the same system multiple times). Once the drag and drop is done, we can see the second folder with the variables renamed successfully. As shown below: But my variables in CAD_1 remain the same as for CAD, so it's PLC_PRG instead of PLC_PRG_1, for example. Is there a solution to automate this? I wouldn't want to have to rename all my variables manually, considering that in the program where I want to do this, the number of variables is substantial. Lucas.

I solved it by creating a new element of IElement according to the ElementExample (MyElement) in the ElementCollectionsExamples project. The variables in this element can then be defined in any properties as needed.
