Post by paulpotat on cm4 runtime problem ^{CODESYS Forge talk (Post)}
Hello again, After looking into it, I noticed that the release note of "CODESYS Control for Raspberry PI 4.13.0.0" mentions a bug fix titled "Support Compute module 4". Is it possible to have more details about this fix from the CodeSys team please ? Because I have several CM4 boards with the same hardware revision / OS but some of them works with the 4.10 runtime and others only works with the 4.13 runtime...

Post by dkugler on TargetVisu Freezing ^{CODESYS Forge talk (Post)}
The only weird situation i remeber with particular or complete frozen target visu was after the rtc clock was fallen or set back to the past. It looked like after running a while the alarm history database crashed during writing entries at a date lot of years in the past. After setting the rtc clock to actual date/time and deleting the alarm db every thing worked fine. I don't know, if this is/was a problem of our PLC hardware/firmware? Maybe check date/time at your system?

Post by garmusd on Raspberry Pi 5 GPIO not working. ^{CODESYS Forge talk (Post)}
I paid money for the RPi runtime because the Product Description says that GPIO is supported. It is also written in the Versions that since 4.11 RPi5 is supported. And I use 4.13. Nowhere is it mentioned that GPIO is still not supported... It's a pity that the Codesys developers still can't find a way to fix it. Are there plans for when it will be fixed or are the developers too weak? Just wondering, is there anyone with a working GPIO? Can you share the details of your system?

Hello, I have a Exor HMI with 2 seperatred ETH interface's. It is Configured as PN Master on ETH interface 1 and the IO's are working, as long as the development PC is connected to the ETH 0 interface. When the PC is disconnected, the PN communication drops and a reconnection is started. I installed the newest device description for Codesys and Firmware for the Panel. The IO Gateway is from Weidmueller What could cause the Problem?

Post by pernockham on Is there a pragma for init/instantiation of local variables in FB (like in Methods) ^{CODESYS Forge talk (Post)}
Im using a pointer as input for a FB and for convenience I like to use 'referenced' variable internally. I use this setup in methods which works because internal variables are instantiated for each call. In a FB these variables are instantiated and initiated for the first call only. Is there a pragma/attribute available that changes this behaviour to mirror a 'method'-call?

Post by ben1 on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
When you say it does not work, does nothing happen or do you get an error? I have not used this function in codesys but from my past experience with Modbus I believe the coils need to be contiguous, which may be why yours is failing? Have you tried using Write Registers (16) to do the job? Or is their data in-between you do not want to edit in the transaction?

Post by garrian on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
Thanks for your reply. I belive it is contiguous, I'm writing to adress 0 to 4. Or, do you mean something else? Well, something is happening. If I on the client set adress 1,2,3 to true, only 1 is set to true on the server side. On the client side, the data is array of word. But on the server side, the coils are array of bool. Holding register is array of word on server side. Can this be a problem? Attached screenshot of how it looks at the server side.

Post by ph0010421 on Task time too fast? ^{CODESYS Forge talk (Post)}
Hello I've made an FB which is a TCP server. It uses the excellent CAA NetServices library. If I have the FB in a task <4ms, then the RT crashes immediately at boot up. If the task >=4ms, it starts and runs perfectly. This is even if the block is not doing anything; just instantiated. Am I missing something silly? Why would a low task time cause this? 4ms is perfectly adequate, but I'm just interested why... thanks PH

Post by dsa28 on EL6910 as a PROFIsafe F-Host in Codesys ^{CODESYS Forge talk (Post)}
Hello All, Does anyone have experience configuring a PROFIsafe communication between EL6910 (F-Host) and and a F-Device in Codesys? I would expect that the PROFIsafe configuration process would be pretty similar as the FSoE configuration. Although, when an F-Device is included under PN-Controller, Codesys doesn't allocate a PROFIsafe logical device automatically under EL6910, as it happens when a FSoE slave is added under EtherCAT master. I thank anyone in advance who can help me on this.

Post by micik on PLCOpenXML Export/Import with Visualisation ^{CODESYS Forge talk (Post)}
I have noticed that Codesys doesn't provide option to Export any Visualization objects even though there is option to check to export VISU_TASK, which is strange because when Import in another empty project, user will end up with build errors. I understand that probable reason for this is that PLCOpenXML specification includes only "PLC" parts of the project (POU, PRG, variable lists, device ....), but not sure about it. Perhaps, there is some option to include visu objects also in the plcopen xml export list??

Hello, I'm using Codesys 3.5.20.0 version and I noticed that even with the most basic standard project create, there are error messages like shown in the acttached picture. The similar questions are already asked here on the CODESYS Forge Talk, but remained unanswered. Exact screenshot is attached, but essentially I would like to know which component in the Codesys has CmpID = 0x00000019 and what this Timeout means?

hi, i used another way declaration: pApp : POINTER TO APPLICATION; pAppInfo : POINTER TO APPLICATION_INFO; ProjectName : STRING (24) ; CodesysVersion : STRING (15) ; code: //library : // CmpApp // IoDrvEthernet // // Get Pointer to current application pApp := CmpApp.AppGetCurrent( pResult:= 0 ); // Get Pointer to Application information pAppInfo := CmpApp.AppGetApplicationInfo(pApp:= pApp, pResult:= 0 ); ProjectName := pAppInfo^.pstProjectName^ ; //convert codesys version to string CodesysVersion := IoDrvEthernet.UDINT_TO_IPSTRING ( udiIPAddress := pApp^.udiPSVersion ) ; so i think you need to convert your dwVersion in a UDINT and after convert UDINT_TO_IPSTRING

gatto, That works. Thanks. Typically I use my mouse more than my keyboard. That's why I was looking for a delete option from the right-click context menu or a delete button on a toolbar at the top. It never occured to me to use the keyboard. It might be a little more user friendly if they allowed a mouse wise ability to remove a line from the grid as well as the DEL key. Just a suggestion. Thanks for your help.

Post by eoahe on Problem Reading Registers via Modbus from non Codesys device ^{CODESYS Forge talk (Post)}
Hey Guys :) I have the following Problem using Modbus via Codesys: I'm trying to implement a Modbus Device into my codesys project. The device is a Router from Teltonika (RUT956) and it can communicate via Modbus. Currently I'm trying to implement it into my codesys prject as a slave and I'm using my windows computer as master. As it is not a codesys device (the codesys application is not uploaded to device as it has its own software) I'm having problems requesting and reading registers from the router. I've set up my windows computer as Master and implemented the router as slave. When I go online on my master device it sais that it has established a connection to the slave (router)(So I'm thinking this could work as there is a connection?). The goal is to read the GPS (latitude and longitude) data and on the homepage of teltonika you can find the register address and number of registers (adress 143 for latitude and 145 for longitude; both have a number of two registers). I've found tutorials how to read specific registers via their register address with other modbus programs (like modbus-cli), but as my entire project is established in codesys I was hoping to read these specific registers via codesys so that I can show the GPS data on my dashboard. I've tried establishing slave channels but that hasn't been working. I tried read input register channels of the length 4 but it's not possible to define specific register addresses to read via codesys so that didn't work (I jsut get a slaves device failure) and I've also tried establishing 516 (total number of registers the router sends I think?) read inputregister channels but that has the samle failure... So i guess the problem I'm having is establishing slave channels to read these specific registers. Does anyone know how to tackle this problem and has maybe had the same problem? Or maybe someone knows a workaround? I'm quite new to codesys so maybe I'm also lacking expertise...

Post by pistola on Pause Tab Order ^{CODESYS Forge talk (Post)}
I'm programming an HMI, and on a settings page I have external buttons allow the operator to tab between various elements to select which one they want to adjust. I then use "Input Configuration" > "OnMouseClick" to select which variable to adjust. The problem is, when adjusting the variable the pointer will move to the other elements within the tab order. Is there a way to pause or prevent the pointer to move to the other elements when a variable is TRUE?

Post by atone on Change IO-Link Device Interface connected to a Profinet-Slave at Runtime ^{CODESYS Forge talk (Post)}
I need to be able to update (change) the interface of an IO-Link device at runtime. The reason is the connected sensor can be selected at runtime, and some sensors we use have a 2 byte IN interface, others have a 4 byte IN interface, others 16 byte IN, others 16 byte IN/OUT (see attached screenshot). Is it possible at all? When yes, which function should I use? Thank you!

Post by simone on Preferred way of managing Ip-adress/es for linux (debian) host? ^{CODESYS Forge talk (Post)}
Hi pernockham, I think you should ask your device vendor. For some time I used one from an Italian company where they had made a library where you can manage the ip with a function (something like SetIPAddr...), it was based on connmann on linux. From my little experience is better to use the "default" way, so for me is to manage the config file on interfaces or use the ip addr utility
