Post by wbj0t on Global variable access by Programms and Modbus Devices (attach device to bus) ^{CODESYS Forge talk (Post)}
Hi everyone. I use Raspberry Pi 4, one core codesys SL. I have a question about global variable access via programm when I glued the same variable to MODBUS SERIAL/TCP DEVICE holding register. So, the question: what behavior of this modifying? When I set "Always update variables (in bus cycle)" and set some task as bus for the Device, then in another task I cant change this varible (can, but immediatly the old value setted again). But the same things works with MODBUS SLAVE: again "Always update..." and master attached to some task, then I change variable in another task and all works. I cant set up my variables from retains file at PrepareStart event because of this behavior with MODBUS SERIAL/TCP DEVICE. Thanks, wbj0t.

Most FBs clock on the rising edge so if they are never called with xExecute = False then subsequent actions will not be performed.

Post by ucconversions on displaying all incoming CAN bus messages ^{CODESYS Forge talk (Post)}
Hello Im using CAN API Im receiving CAN messages with no problem. below is my code. METHOD ProcessMessage VAR_IN_OUT ( Incoming message ) Message : CAN.RxMESSAGE; END_VAR VAR i: USINT; END_VAR recvCANid := Message.udiCanID; IF recvCANid = 16#18FF8247 THEN UserVarGlobal.g_countMsg_RPMset := UserVarGlobal.g_countMsg_RPMset + 1; FOR i := 0 TO 7 DO myDataFF82[i] := Message.abyData[i]; END_FOR END_IF but in this way I can only display CAN messages which I know its ID. I want to display all incoming CAN messages for example first incoming CAN message - I assign it into a variable Message1. second incoming CAN message - I assign it into a variable Message2. third incoming CAN message - I assign it into a variable Message3. Can you give me guidance? Thank you BR

Yes, this point is part of my misunderstanding. Why, after the execution ot the motion FBs is set to FALSE and exsecuted at lest one time, it must be continuosly called, even if the motion control it's take from another subsequent instruction. This is what I really don't undertand, but what in fact it's happening. For example, in case of stopping a MoveVelocity FB, then Halting the motion by the related FB, the axis at spot goes into error. If there was bad trigger management, the various instructions would NEVER work.

I was answering your last paragraph Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work).

Maybe the example posted it's not so clear, but this is not the problem. The execution of every motion methods is well triggered.

Hallo, ich möchte einen Datenlogger schreiben für den Webdatenplotter der Wago. Ich habe jetzt das Problem dass der Baustein keinen Zugriff auf die Festplatte oder SD-Karte hat. In der Codesys kann ich über die Dateienansicht auch die Speicherkarte nicht sehen. Über FTP in Windows jedoch schon. Kann ich in der Webvisu vom Controller etwas ändern um daran zu kommen? orientiert habe ich mich an dem Anwendungshinweis von Wago und dem Video welche in E-Cockpit sind. Daten werden über Real normal geschrieben. Firmware ist die 26. Codesys ist die SP19 Patch 2.

Post by nico-hefr on Python script command for "Access Control" ^{CODESYS Forge talk (Post)}
Hi everyone, I use Python Script to generate some POU in Codesys V3.5 SP19 and I would like to limit the "Access Control" to them thanks to the Python command. Is there any commands that allow to edit the "Properties... >> Access Control" of the POU? The other possibility is to set the permissions with "Project >> User Management >> Permissions... >> Project objects >> Modify >> ... >> myPOU", but I did not find the related Python commands. Otherwise, is there a global setting that allows to set the permissions by default? For example, Modify = Denied for everyone user by default. Thank you in advance for your help, Nico

Hi Ricardo. I was having the same problem with Codesys and a Raspberry Pi 2W while using the GPIO uart. Your post helped me a lot. Thanks! But could not understand why MODBUS parity bit makes Codesys MODBUS COM driver stopping to work after first request transmission. Did you see this @eschwellinger ? Regards, Nelson

Post by trusty-squire on Confused by dwIpoTime input for SMC_Interpolator ^{CODESYS Forge talk (Post)}
Hi, Learning Codesys CNC, and I am confused by the dwIpoTime parameter. I have a basic demo application, using SMC_Interpolator feeding into SMC_TRAFO_Gantry2Tool2, which then sets the position of the x/y SM_Drive_Virtual axis. I also have a C axis which revolves the tool, which is controlled using a simple tangential angle calculation SMC_CalcDirectionFromVector. The GCode I'm using has feed/accel set at 500. The axis configuration limits are well above that (2000). What's strange is that, when I run the simulation, the feed speed changes drastically when I update the variable dwIpoTime. The larger the number, the faster it moves. What's going on here? The documentation only says "This variable has to be set for each call. It represents the cycle time in μsec." Why does it change the feed speed I'm seeing the in simulation? What is a good number to use? The example I was looking at set it at 5000. Screenshot attached.

Post by mmpl on Array to String ^{CODESYS Forge talk (Post)}
I would like to create one large JSON string from an array of objects, where each object contains a value. My current approach involves using a for loop and string concatenation, but with 20,000 elements in the array, this method takes almost 7 seconds and negatively affects the PLC scan time. Is there a more efficient way to accomplish this?

Post by programmierer on UDB Block in Codesys V2.3 implementieren um Werte an bestimmte IP-Adresse zu senden ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich möchte mich hiermit an euch wenden, in der Hoffnung, dass ihr mir bei meinem Problem behilflich sein könnt. Ich bin neu in der Programmierung und arbeite aktuell mit einem Wago Controller in unserem Labor, der eine Wärmepumpe steuert. Mein Ziel ist es, vier spezifische Werte an eine bestimmte IP-Adresse zu senden. Dazu habe ich versucht, in das vorhandene CODESYS-Programm der Wärmepumpe zusätzliche UDP-Blöcke einzufügen, um die Datenübertragung zu ermöglichen. Leider hat das Senden der Daten bis jetzt nicht funktioniert. Ich habe auch Bilder der Blockkonfiguration beigefügt, um einen besseren Einblick in den Aufbau zu geben. Über jegliche Hilfestellung würde ich mich sehr freuen. Vielen Dank im Voraus!

Post by drml on How to implement an interface (IElement)? ^{CODESYS Forge talk (Post)}
I'm struggling with the implementation of the IElement interface (in the ElementCollections library), which I will use to create a SortedList. I created a class (FB) "Device" that implements this interface and that has a "Priority" property that I want to use in order to compare the devices in my implementation of the ElementCompareTo method. Unfortunately, the IElement.ElementCompareTo method needs an IElement as an input, which doesn't know about the "Priority" property of "Device". I tried to define the input itfElement as a Device, but then it doesn't want to compile, because the type in the implementation doesn't match the interface.

Post by peterned on Programatically restart Codesys OPC UA server? ^{CODESYS Forge talk (Post)}
Hi, I'm using a Festo Codesys PLC (CPX-CEC-C1-V3), which is connected to a HMI panel. Both exchange data via OPC UA. Occasionally, the HMI stops displaying data, and looks as if there is no connection. If the HMI stops, the only way to make it work again is to restart the PLC. Restarting HMI has no effect. When the PLC is restarted, HMI starts working normally again. Is it possible to restart the OPC UA server from PLC code? I hope this will make fixing the HMI possible without a PLC restart. Thanks
