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 eozupek on File Transfer Error 4 ^{CODESYS Forge talk (Post)}
I couldn't exactly solve the file transfer when I wanted to do multiple transfers while the compiler was open in a way that I couldn't understand. Notification from target: runtime received SIGABRT - system may be in an inconsistent state * We recommend a reboot of the controller now! * details of the target component that sent this notification: [CmpName=SysExcept, CmpId=0x00000103, ClassID=0X0001008, ErrorID=0X00000001, InfoID= 0X0000000j] I see the warning. I couldn't find out why error code 4 is coming or what kind of measures I need to take to prevent it from coming within the application. Can you help me? regards Emre OZUPEK

Post by mkintegration on Reading Absolute Encoder Position From Yasakawa Drive ^{CODESYS Forge talk (Post)}
I am looking to read in the absolute position of a yaskawa servo drive Sigma 7 that is using absolute encoder. It looks like yaskawa outputs this across there CN1 I/O connecter and during operation just outputs encoder pulses. But at boot up transmits the Multiturn data position and the Position within one rotation (pulse train) on two different wires. Once the drives are enabled it just uses incremental pulses. Does any one have experience with what IEC blocks to use to read this information in. I attached the Yaskawa Manual section that talks about the format.

Post by viksym on How to get the motor scaling value from code ^{CODESYS Forge talk (Post)}
If anybody finds this in the future, I managed to do it like this: scalingValue := EncoderPulseCountPerRev / ABS(AxisName.fScaleFactor); No need to use MC_ReadParameter as I am able to read this value directly from the axis object. Using an absolute value of the fScaleFactor is there in case the axis is set as inverted, in which case it would be a negative value. I was not able to figure out how to get EncoderPulseCountPerRev programatically, but since all my servos use an encoder with pulse count per revolution of 16#800000, the final equation looks like this: scalingValue := 16#800000 / ABS(AxisName.fScaleFactor);

Post by jzhvymetal77 on IecVarAccessLibrary.IBaseTreeNode methon ^{CODESYS Forge talk (Post)}
I got this code working again. 3S/CoDeSys, your level of obfuscation and lack of documentation turns a simple task into a monumental complex challenge. The issue was that at some point the IecVarAccessLibrary changed and no longer allowed using IBaseTreeNode to retrieve a child or the number of children. The attached code has been updated to use IIecVarAccess6.VarAccBrowseGetChildByIndex instead. The code was also cleaned up but is still a work in progress. The current example only works one layer deep. This means native data types, arrays, and single-layer structures are supported. However, structure arrays and nested structures are not yet supported.

Post by kevinl on RevPi Connect RS485 ^{CODESYS Forge talk (Post)}
I figured this out on my own with this logic: usually the Serial port on a Raspberry pi is on /dev/ttyUSB0 then you need to set linux.DeviceFile=/dev/ttyUSB in codesys you then must set com port to 1 so i assumed codesys subtracts 1 from the number and adds this to the filename... (in code it would look like this: var comPort : byte := '1'; linuxDevice : string := '/dev/ttyUSB'; filename : string; end_var filename := concat(linuxDevice, (to_string(comPort-1)); filaname then is /dev/ttyUSB0 RevPi uses ttyRS485 as Serial port so you must remove the last number from the name and set the com port to this number +1 i hope this is understandable ;-)

Post by timvh on CODESYS V3.5 SP15 Patch 2 won't open ^{CODESYS Forge talk (Post)}
This is almost always related to previously working with an additonal monitor. If you have placed CODESYS on that monitor, later start your laptop again and open CODESYS without that monitor, then Windows still places it in the previous position, but then it is not visible. So the solution by cehermanstad can be used to move it to the main screen to make it visible again. PS, another way to move it, is by pressing SHIFT and then right-click on the icon in the task bar, then select move. You can then move it with the arrow keys or your mouse.

Post by mp9876 on Problems with simulation in Window 10 ^{CODESYS Forge talk (Post)}
Hi Automa, it seems the solution you were bringing up on 2022-04-06 could really help me as I did not remember the password I initially set. My problem though is that I am using Codesys Control Win V3.5 SP19/60 (64 bit) and I cannot locate any of the files you listed up there. I have been looking inside folder: C:\Program Files\CODESYS 3.5.19.60\CODESYS\ and they appear not to be present at all neither in the CODESYS folder or any sub-folders. Uninstalling and re-installing unfortunately does not do the trick. Any idea how I could get out of the ditch on this issue ? Anyone else maybe ? Thanks

Post by garrian on How to sort JSON object in codesys ^{CODESYS Forge talk (Post)}
Hi there, I'm testing out MQTT from my Wago PLC using JSON object. I have managed to publish this {"Temperature":15.6,"Setpoint":38.0} to my broker. Now I', trying to subscribe to the same message. The result is this: '{"Temperature":15.6,"Setpoint":38.0}95}ê$10šå$04$Nå$08²Ÿå$0B` á$08@šå' First, why do I see 95}ê$10šå$04$Nå$08²Ÿå$0B` á$08@šå' at the end of the message? Second, how Can i sort out this data to use it in my program? I followed a youtube tutorial which gave me the attached result, which works. But I need some other smart way of doing this when the object gets even more data in it. Any help is very appreciated :)

Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
I don't know why the EtherCat fails, but what happens is: First I have only one 1WireMaster running on my Raspberry Pi and EtherCat is running fine. Then I'd like to add a 2nd 1WireMaster. Therefore I enable a 2nd GPIO Pin on the raspberry in the file "/boot/firmware/config.txt". dtoverlay=w1-gpio,gpiopin=4,pullup=0 dtoverlay=w1-gpio,gpiopin=23,pullup=0 To be able to use this 2nd 1WireMaster in Codesys Runtime I Adjust the CODESYScontrol.cfg file and add there: PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ After a reboot the EtherCat Master is not working any more. I didn't even add a 2nd OneWire Master in Codesys, but still if I do the EtherCat does not work. Do you have an idea why?

Post by fari on Configure J1939 I/O Mapping via Scripting ^{CODESYS Forge talk (Post)}
Hi everyone, With the latest version of Codesys, it’s now possible to import DBC files directly into the J1939 Manager, which is great. However, I’m trying to achieve the same thing programmatically and can’t find any scripting functions related to import_dbc or any host_parameter that would let me configure PGNs and signal mappings automatically. So far, I’ve managed to add the J1939 Manager and an ECU, and I can pass the DBC database to it, but I’m stuck when it comes to adding the signals. Has anyone figured out if this can be done through scripting? (Attached is an illustration of what I am trying to accomplish programmatically). Thanks in advance.

Post by timvh on Version management ^{CODESYS Forge talk (Post)}
This depends on what you want to achieve with installing the latest version and how you manage your projects and repositories. Maybe you also want to update your device (right click on it to update) or maybe your device is depending on certain versions of libraries (go to the library manager in your project and download the missing libraries). An option is also to first create a projectarchive of the current project you have before you install a new version of CODESYS. Then you can open this projectarchive in the new CODESYS version. Especially if you install the latest version of CODESYS in a Sandbox.

Post by dkugler on Visualisierung: Tastatur vergrößern? ^{CODESYS Forge talk (Post)}
mir ist kein Scallierungsparameter bekannt bisher. Als Workaround fällt mir folgendes ein: für keypad und numpad jeweils eine zusätzliche Visualisierungen erstellen, welche lediglich einen Frame enthält, der wiederum das originale numpad und keypad aufruft. Über die Eigenschaft relative Bewegung X & Y könnte dann der Frame sogar zur Laufzeit über eine Variable in der Größe angepasst werden. Die beiden ersellten Visualisierungen muss man dann noch im Visumanager unter Dialogeinstellugen als zu verwendende Numpad und Keypad entsprechend zuweisen. Nachteil: Visu-Scallierungen sind oft Spritfresser, sprich gönnen sich ordentlich Rechenleistung. Viel Erfolg!

I've got a Weintek HMI with CodeSYS built-in. I've got it connecting to CodeSYS and downloaded. The connection guide says I need to add a symbol configuration by right-clicking on the application and adding it, but it does not show up in the available objects. Is there something else I have to do to create a symbol configuration object?

Post by timvh on Send file from codesys to...... ftp, cloud, etc ^{CODESYS Forge talk (Post)}
You can use the (open source) FTP client in Forge. This works on 64 bit systems. See: https://forge.codesys.com/prj/ftp-client/code/HEAD/tree/ As this is open, the idea is that when you use it and make improvements to the source code, that you also commit this in a branch so others can also benefit from it.

It seems that there is a limitation with the STRUCTs. Does anybody know, what’s okay to save (add to the recipe) and what’s not okay? Or is there another problem with my project? If I have only an array in the recipe definition everything works perfectly (see project).

I have created an EtherCAT slave code and fixed two slaves (IDs written in the 0xF050 object dictionary). The module IDs are 0x1 and 0x101, respectively. It can be scanned normally in TwinCAT, but when scanning in CODESYS, it reports an error. Why is this happening？text in the second pic means 'device cannot be found in repository'
