Post by trprsmn on "Scan Network" doesn't find CR1140 device (ifm) CODESYS Forge talk (Post)
Hi, I'm watching an ifm tutorial on how to setup an industrial controller in CODESYS. I'm using an 'ecomatDisplay43inch_64bit) controller. CODESYS Gateway and PLC are both runngin (systray). However if I click "Scan Network" I can't find my controller. The only thing it finds is a "desktop" it seems (I'm using a Windows 10 on a Mac Book using VMWare, so maybe it has something to do with that?). How can I fix this? Thanks in advance!

Post by andrej on Creating, using an external Function. CODESYS Forge talk (Post)
Hello all, could you tell me whether I need an additional license in order for v3x64 to execute the DLL? Is there some manual on how to proceed? Other than the rather generic message loading Component failed Lib_XMATH.dll I have no further hints. Many thanks for your feed back. PS: I tried a similar experiment (i.e. generating a native dll for windows and having it executed by the Python VM this worked without an issue).

Post by cd-tt on cannot connect ot linux runtime: device does not answer the scanrequest CODESYS Forge talk (Post)
I have the following setup: Proxmox PC with a debian 13 VM running CODESYS Control Linux SL and Edge Gateway. Installation method was through the Deploy Control SL and went rather smoothly. In my Device Tab I find the gateway and when scanning my network I also find my runtime. I want to connect and get promted that I should add a user. After setting up the user I get an error saying, that the device is not responding my scanrequest. Deploy Control SL Operation saying everythings up and running. I can confirm that from the terminal on the VM with "systemctl status codesyscontrol" and "systemctl status codesysgateway". I am running out of ideas how to fix that issue. Can anybody help? Screenshots attached.

Post by wiresplus on INT_TO_WORD function not working CODESYS Forge talk (Post)
Hello, I need to take an INT input, and convert it to a WORD value. VAR DRV2Speed : WORD; //IO card takes a WORD where 16000 = full 10V output (equivalent to 50Hz) PumpFillSpeed : INT; //Users enter a value between 0 and 50 END_VAR IF <conditions> THEN DRV2Speed :=INT_TO_WORD((PumpFillSpeed/50)*16000); END_IF </conditions> According to me this should work - but it stays at 0, no matter what. What am I doing wrong?

Post by eschwellinger on License problem gateway CODESYS Forge talk (Post)
I just try to help. Anyway it is a big difference if a Store SL runtime or an oem plc and licence is used. These licenses need to be activated on plc side - so you have dependencies to the version (CODESYS and Runtime Version) Did you ever ask Epis out for this situation? They should know which license fit to their device. Even they should know if the device is capable for Softmotion and see the requiremnts in the CODESYS store: Runtime 4.9.0.0 - how should this work with Epis 3.5.16.x? Anyway refund is not a problem.

Post by bertcom on Converting each character to a string into ASCII CODESYS Forge talk (Post)
Good afternoon, I have a project where i need to split a string and send it in ascii code to an Domino Printer. Concept: i get an String from an Zebra scanner looking like this : " R002043;5410761402862;Oil Plus 2C Comp.A - Gris Belge;1286193824;" To start is the ";" the seperator. i found some functions to delete the ";" in a string. this is okay but now i want to convert each digit in the string into ascii like this: R=82 0=48 0=48 2=50 0=48 ... This because the printer wants to receive a string like this: <esc>OQ001TE 82 48 48 50 48 ...<eot></eot></esc> Anyone who can help me with setting me on the right track with some advice?

Post by hemuv on Dialog Open CODESYS Forge talk (Post)
I'm programming an HMI for a machine. I want to log all the parameter's changes (used text field for displaying and changing) for particular User levels. Created a Numpad and want to log oldvalue and Newvalue on 'ok' Button press. To retrieve the oldvalue, i check if the dialogue opened is my Numpad, Then I retrieve the dialogue interface via GetDialogInterface(ADR(myNumpad)) --> numpadData.stVariableValue which contain my oldvalue and save it locally. Problem is sometimes i retrieve the data and sometimes not. Also observed when Numpad Dialogue is Opened, VisuDlgUtil_IsDialogOpen returns False in some cycles.Attached you will find my Project. please let me know what went wrong or if there is a better approach to collect old and New Value of a textfield. Thank you.

Post by alex-at-xana on EThercat Dynamic configuration CODESYS Forge talk (Post)
Ah - forgot another question as it may be related to the PLL problem: I am executing a 4ms cycle. I do not call (from what I know) the Ethercat_MAster periodically in my program. The bus cycle task is set to the Ethercat task. I would assume that the master should send 250 frames per second. Yet, the status of the master says it transmits 500 frames per second which would indicate that the master is called twice. Any ideas there?

Post by winki on Modbus TCP & RTU with Control for Linux SL CODESYS Forge talk (Post)
For small project, I would like to use my industrial computer as a PLC + Industrial Computer. Like that I can save the cost of one PLC. That why I am using Codesys on Linux. With the nic it is not working. I already set the IP adress with /etc/network/interfaces. Can it comes from there ? looking to "Control Linux SL" docuemntation it should work with rtu.

Post by kirsipr on Color of empty table and table header CODESYS Forge talk (Post)
I have managed to change my dynamic visu table colors with the template for each column to dark like my rest of the webvisu background is. How ever the empty table (when not populated) and the table header stays white / gray. Is there same way to modify the colors of header and empty table?

Post by timvh on CAN Open Manager - varible of SYNC CODESYS Forge talk (Post)
You can enable "Sync Producing" in the configuration of the CANopen Manager. Then this manager will send a SYNC message every interval you set. Depending on your PDO configuration, the CAN nodes can send a PDO on every Sync (cyclic-synchronous). If this is not possible, then as alternative you can send a low level CAN message with COB-ID 16#80.
