Post by usacodesysuser on How to connect serial devices ? ^{CODESYS Forge talk (Post)}
@eschwellinger do you have any examples of using a USB barcode scanner? I have read through the forums here and I am unable to find how to get the barcode data to populate in a text field without having to first click into the text field to activate it. Is there a library that allows you to access the barcode data? I am really new to this in general any help is greatly appreciated, hopefully you have a pretty clear example

Hello, I couldn't figure what/where the issue was, so I deleted everything from automation server and reinstalled the edge gateway and did the process again. It worked for about a month and then it stopped working again. It presents the same symptom, edge gateway is online but I can't connect to the PLC. Any idea of what could be the issue? Thank you!

Hi Edwin, The PLC is already in the automation server so nothing happens when I scan the network, however the PLC show offline (not connected). Please see logs below.

Post by sturmghost on Visualization using methods and cyclic ST-calls ^{CODESYS Forge talk (Post)}
I found a way to do it: You can use, for example, the text variable property of any visualization element and call a function in it. Example: Write a test POU as a function (FUN), like MyTestFun which need a boolean Variable as an input value. Now write into the text variable property: MyTestFun(bBooleanValue) Thats it. The function is called at each visu_task cycle.

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 wiresplus on Cannot get INT_TO_TIME working ^{CODESYS Forge talk (Post)}
Hello, I have a simple TON timer. It is watching prime loss for a pump. The operator can set the delay via the HMI, it is an integer (seconds) As the TON uses milliseconds, we then multiply the entry by 1000 to get seconds. Seems simple, but... VAR PrimeTimer : TON; primetime : INT; END_VAR PrimeTimer(in:=State>0 AND FlowRate<MinimumFlow,pt:=INT_TO_TIME(primetime *1000)); For an entered 15 seconds (VAR primetime:=15;) the timer reads 49d17h2m26s760ms !!!! What am I doing wrong?

Post by ojz0r on INT_TO_WORD function not working ^{CODESYS Forge talk (Post)}
That calculation will not work the way you expect it to. If PumpFillSpeed is limitied to 0-50 then the only whole number would be 50/50 = 1 everything else is 0.0-0.9999... and since you are using word and integer only 50 would work since there is no representation for mantissa in integer values. Declare a temporary real variable and do the calculation and then do a REAL_TO_WORD in the DRV2Speed assignment.

Hallo, ich muss im Rahmen einer Hausarbeit die Steuerung einer Geschirrspülmaschine erarbeiten. Leider bin ich mit dem Programm noch nicht so vertraut und habe Probleme bei meinem Zeitschalter und finde leider selber das Problem nicht. Deswegen zu meiner Frage ob mir jemand helfen könnte. Und zwar kommt das meine Variablen nicht deklariert sind und ich finde aber nicht wieso. Die zwei Screenshots zeigen nochmal den Zeitschalter und das Programm wo der Zeitschalter eingesetzt wird. Vielen Dank im Voraus.

Hi, ich ich möchte prüfen ob eine Datei existiert. Wenn diese nicht existiert, soll eine erstellt werden und dort hinein geschrieben werden. Die Datei wird im Programmlauf mehrfach geöffnet und Daten hinein geschrieben. Ich will hier die Funktion File.MODE.MAPPENDPLUS benutzen, das funktioniert aber nicht. fopen.xDone bleibt false.

Post by timl on BacNet Server ^{CODESYS Forge talk (Post)}
Hallo, für einen BacNet2 Server lassen sich mit zwei Ethernet Schnittstellen auch zwei Bacnet 2 IP Datalinks anlegen. Einen Datalink nutze ich für den UDP Port 47808 und einen für den UDP Port 47809. Dadurch ist der Server aus beiden Netzwerken erreichbar, was so gewollt ist. Allerdings verbindet er die beiden Netze auch miteinander, was zu Kommunikationsproblemen führt, da in beiden Netzwerken bereits gleiche Device ID's vergeben sind und diese sich dann doppeln. Lässt sich diese Verbindung der beiden Netze abschalten? Gruß Tim

Try using a password instead of a public key to log into the controller. I have a video showing how to do this on a default installation of Ubuntu server, it should work the same for Ubuntu Core. https://youtu.be/rj0dOhgnGjs?si=352PmveEP7JXZnO- I sign in to the controller at about 6:40 in the video. I have never tried to remove the public key and revert to signing in using a password, but it looks pretty straightforward https://askubuntu.com/questions/745423/how-to-turn-off-password-less-login-for-ssh

Hi, I'm trying to get Scaling working on my axis. An increment produces 36.6mm of movement, so I want to put the units in application as 36.6. However the docs say that I need to change bHiresMode as it doesn't show me the option for Precision in the User Interface. I'm thinking that I need to change the precision so I can enter decimal places. How can I do this, or is my thinking wrong? Thanks,

I have two ethernet Ip drives and created Function Blocks for different motions tasks. I am using same FB for both the drives. When I try to execute the relative move start command on FB for both the drives it is not working. However, if I add 1ms second delay between the execution of each drive it is working. Also when I change the rung order it is working for the first drive in the rung. what could be the wrong here?

I also tried the option to "Perform static analysis automatically after compilation" # get Project values myProject = projects.primary # Creates an active application app = myProject.active_application # build Application and run static code analysis app.generate_code() Could you please offer any insights into why this might be occurring?

If user dev3og5 has same permissions as Owner user; why would it not be authorized. I am at a loss; any assistance would greatly be appreciated. Thank you Mike
