Post by gseidel on The default ramp type selection in SoftMotion V4.18.0.0 is Quadratic ^{CODESYS Forge talk (Post)}
Hi imdatatas, thanks for your feedback. This change was intentional, as the quadratic ramp type has many advantages over the trapez ramptype. Sorry to hear it causes problems in your situation. Can you please shortly explain the nature of the problems? Best regards, Georg

I have exactly the same problem and tried entering “ForceIecFilePath=0” in the file “CODESYSControl.cfg” ([SysFile]). Unfortunately, this was unsuccessful. Can anyone help in the meantime, e.g., with some sample code or with the FAQ that TimvH refers to above (link no longer works)? Many thanks and best regards

Post by gseidel on can not new a cam table in codesys V3.5 SP20 ^{CODESYS Forge talk (Post)}
Hi liai, is it possible, that SM3_Basic is missing in the library manager? (It should be inserted automatically when adding a Cam table, along with the other motion libs.) You can add it manually and see if that solves the compile errors. Best regards, Georg

Hi, I have a question. Does anyone know a way to change latch alarm variables from the PLC runtime? In the help there is a method described: https://content.helpme-codesys.com/en/libs/AlarmManager/Current/Interfaces/pou-IAlarm3/SetLatchVarValue.html but I don’t know how to use it correctly.

Hi liai, I tried it with a fresh CODESYS SP21 Patch 2 installation and SoftMotion 4.18, but cannot reproduce the compile errors. Could you please upload a project archive that has the errors? Then I can have a deeper look. https://dl.codesys.com/s/q4KcbKCcZndg6oR Best regards, Georg

Post by cer-wa on Not able to connect multiple profinet encoder in codesys Linux ARM64 ^{CODESYS Forge talk (Post)}
Hello, currently im working with a RevPi connect 5 on a codesys project. Up until now I was having a blast because things were going really smooth but for like almost a day im kind of stuck on the integration of multiple profinet sensors into my project. This is kind of a bummer because that should be an easy thing to do. What I tried so far was to create and additional ethernet adapter where I then tried to connect my devices. in the beginning I tried to connect the devices directly which was not working because I could assign the IP-adress only to the ethernet adapter and not to the devices but the device was found in the device repository (this gets important in the second part) So what I tried next was to setup a PN-Controller and connect my devices subsequently to the Controller. Sadly now the devices wont show up in the device repository anymore. To me its not clear why this is happening. And the worst thing is: I went ahead and setup a device completely like I would want to have it in the project and when I then click on scan devices I can even find the device. But it can not be added to project for whatever reason eventhough im 100% certain that the gsdml file is the correct one. Can anyone help me with this. Like I said this seems like an easy thing to do and its taking me way longer than expected already. The only thing that came to my mind why this might not work is because I have codesys license which only allows one profinet instance. Could that be the case? The error message seems then pretty unfit but ok. I will be grateful for every advice. Thanks in advance! Best regards!

Hello. I'm using Visualization XY Chart, and when I mark a circle through XY position data, a blue line is displayed in the circle with a red circle. At this time, can't I set the blue line not to be seen in the circle? Currently, whenever XY position is drawn, the line follows.

Post by dogulas on numeric text box control ^{CODESYS Forge talk (Post)}
Ok, this is how I made a numeric text field: use a Text Field properties -> Texts -> Text := %f (or %d or whatever you need) properties -> Text variables -> Text variable := (your numeric variable) properties -> Input configuration -> OnMouseDown -> Configure: Write Variable Input type := VisuDialogs.Numpad Use another variable (your numeric variable) Min val Max val etc. Please tell me there is an easier way to do this.

Post by jzhvymetal77 on Special Chars in Visualizationfor QR code string ^{CODESYS Forge talk (Post)}
Ok, I got UTF-8 encoding working by encoding the full block character using [16#E2, 16#96, 16#88], which corresponds to U+2588 "█". Moving forward, I’ll use this for creating a QR code with Version 10-M (byte mode). This version allows up to 213 characters to be encoded.

Post by snhatton on How to write a for loop in ladder? ^{CODESYS Forge talk (Post)}
Hi there, little late to the party, but you could also use the ST block for in-line ST code and implement a for loop as you normally would. ST Block is super handy if you just need a small amount of in-line structured text code without creating a new POU. Hope this helps!

Hi, I’m evaluating CODESYS for our devices. If I buy a standard runtime and the Toolkit, can I create a custom device descriptor so users can select my device (instead of just “CODESYS Control for Linux ARM64 SL”) when starting a new project? Has anyone done this or know if it’s possible? Thanks!

I think I struggle with the same issue. I tried the currentVisu variable but this is the active Visualisation. I have a dialog with a frame with frame configuration like in the picture. I would like to use the index te be used to make a button look like it's pressed/selected.

Post by snhatton on Testing of Codesys program ^{CODESYS Forge talk (Post)}
There is a tool called test manager that is part of the Professional Developer's Edition of CODESYS. I would take a look at this tool for your testing purposes. There is a free 30-day trial so you can evaluate if the tool will meet your needs before investing in the license.

Post by snhatton on OPC UA: How to change NodeId ?! ^{CODESYS Forge talk (Post)}
You can change the node id by adding the following to /etc/CODESYSControl.cfg: [CmpOPCUAProviderIecVarAccess] CustomNodeName=MyPLC123 Then restart the runtime and the new Node name will appear with the connection. I don't know if it's possible to remove the |var| from the name. I hope this helps!

Post by ph0010421 on TCP/IP client ^{CODESYS Forge talk (Post)}
Hello TCIS_Send needs to be longer than 4 bytes because idata is 28 bytes long. There may be other ways, but I would make a UNION with string/array of bytes. Write your STRING into the AsString part then copy the AsBytes part into TCIS_Send (Elements [3] to [30]) then 252 would be in [31] (I've assumed the idata is always the same length)

Ich bin leider auch über den Fehler gestolpert, aber selbst in Version 3.5.19.50 ist dieser noch enthalten. Bis 3.5.19.20 kann ich meine Programme noch nutzen. Ab 3.5.19.30 ist der Fehler anscheinend vorhanden. Ich habe leider auch schon einen Haufen Programme mit meiner Library erstellt, somit wäre ein umbenennen nur mit sehr viel aufwand möglich.

Post by sebastian-hk on Codesys auf einen Cortex M4 lauffähig machen ^{CODESYS Forge talk (Post)}
Wichtig ist zudem auch noch zu wissen, ob der Cortex M4 Prozesser für eine Codesys Laufzeit ausreicht, oder ob es einige Einbußen gibt. Hat da jemand Praxiserfahrungen sammeln können? Wie es bei Codesys steht, wird kein Betriebssystem wie Linux oder Windows bei diesem Prozessor benötigt. Somit müsste dieser performant genug sein oder sehe ich das falsch?

So none of the images from the 64bit archive work with any Codesys Control versions? I have tried the last Pi OS with every Codesys Control version and they don't work. I was wondering if there's any stable combination of versions.
