Hello, I'm having the same issue.. were you able to solve this? Anything in particular in the other thread that you linked that helped you solve it?
Is there a way to have both a Public No Login Screens with Screens that do require login and File Transfer? My Idea is to have the default page be View Only with a Login Button in the Corner and then Once Logged In you can change settings and download files depending on your user group.
Hi, I'm trying to accomplish the same, have you had any success? Kristian
VarAccGetAddress does not return the correct address for TYPE_ARRAY or TYPE_USERDEF. When you use VarAccGetNode, it returns a proper IBaseTreeNode if you provide the full path of an array element or structure element, and it even provides the correct data type. The problem is that with TYPE_ARRAY, it returns the start address of the array rather than the indexed element. With TYPE_USERDEF, it only returns the offset of the element instead of the actual address. This causes many issues with nested...
Hi, I imported an old project created with version 3.51.20.50 into the new version 3.51.21.20. I'm using ModbusFB.ClientTCP v4.5.0.0. Strangely, I can no longer download the project due to a licensing issue I didn't have before. The number of Modbus channels has gone from 1 to 54!, and there's no license that would work. Can anyone tell me where I'm going wrong? Thanks Sandro
Hello, I am attempting to implement unit tests for my POUs. When building and running the unit tests I receive error C007: Unknown Type for all types defined in the library, Standard, 3.5.18.0. Which is included in the POU Library Manager. Any input would be appreciated. TIA.

The Special characters that I need to inclue inside the string are as follows; Null Bell Carriage Return I have a TCP_Write command that I am sending to an external device. In order for that device to function properly it needs to see the string with the null and bell characters as the header, followed by the desired command, terminated with the carriage...
I am struggling with this issue right now (again). I have nested structures with configurable array sizes. In the past I ever used parameter list. Very easy way! As of now I cannot find any solution. Ridiculous that they deprecated it without an alternative solution.

Hello, I have a Raspberry Pi 3 which has a printer connected to his USB port. I have a PiFace Board on the Raspberry. I have a python script file (.py) to print a logo + a text. The script is working because when I execute it from the Raspberry terminal it works. Now, when I push a button on the PiFace I would like to execute the python script file to print. How can I do that ? Many thanks for your help and advices!

Change the actual time of your PLC. How to do this sometimes depends on the PLC you use. Please contact the vendor of the PLC to get this information. Or see the following example for using CODESYS date and time functions: https://forge.codesys.com/prj/codesys-example/date-and-time/home/Home/
You don't have to create 2 libraries. CODESYS will handle it automatically based on the selected device in your application.
Which device do you use? Does this have persistent memory (e.g. NVRAM) available? Maybe first ask your PLC vendor about the possibilities and how they advice to use persistent variables? If you have no NVRAM available, CODESYS will store the variables in a file when the device gracefully shuts down. But on an abrupt power failure, this is not possible. If you have no NVRAM and you want to use persistent variables, then consider using a UPS. In this case when the power is lost, the UPS can keep the...
Hello everyone, I downloaded the "Example: PLC Chat Net Base Services" example from the Codesys help site to review and try it out. https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_cds_plc_chat_net_base_services.html However, when I open and compile the example program with SP21 Patch2, I get the strange error message below regarding Visualisation component, and it fails to compile.

Maybe your slave device didn't properly closed its socket port and CODESYS is unable to reconnect? Did you restart your slave device?
I'm not sure, but maybe you need to install or update the "CODESYS Communication" add-on through the CODESYS Installer.
I'm beta-testing a new EtherCAT drive for a rotary (modulo) axis in a system where the encoder resolution is 81920000 counts per rotation. If I enter this in the SoftMotion Scaling/Mapping tab for "increments <=> motor turns", I get the error below on the Commissioning tab. Is SM unable to handle a high-resolution encoder? The bus cycle is currently set to the default of 4 msec (Control Win V3 x64), although I plan to reduce that to reduce latency, possibly by switching to the realtime (RT) master....
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...

Thank you, so "Remote TargetVisu" is the same thing as "TargetVisu"? I think there needs to be more documentation about this, its very confusing.
The fix for this is when you install the control SL license, there is a checkbox for the Visu S license option. You must click this option. The Visu M is technically an upgrade to the Visu S, if this is license is not installed them the Visu M will fail as shown above. Thanks JoJo for the solution!
Hello How to update the dates from timestamp to the actual time? THX!
Hello How to update the dates from timestamp to the actual time? THX!
Looking for thoughts on creating libraries that can be used on both 32-bit and 64-bit controllers. We are currently writing software in CoDeSys for both target types and will continu to do so for the near future. Projects are always unique, no straight forward copy/paste, yet there is enough similarity between them to use libraries for recurring logic. I do not want to create and maintain twice for both platforms if this is not absolutely necessary. I am aware of useful datatypes like __XWORD, __XINT,...

It is not needed to add Targetvisu connector - for using the TargetVisu for Linux. The reason is - TargetVisu for Linux is basically a remote TargetVisu which could connect to any CODESYS plc not only the loacal one - therefore only a Webvisu connector is needed to have it work. & it seems a bug with this anoying update proposal.
When I open the project, I always get this notice. It never actually updates the CmpTargetVisu.. Is this a bug?
Ok, think I understand. The reason for the error is I try to include complex variables (FB) in the persistenced data. I will try to use {attribute 'ac_persist_exclude'} to exclude those elements.
In CODESYScONTROL_User.cfg I have [SysFile] FilePath.1=/etc/, .dat FilePath.2=/home/pi/DataLog/, .sqlite, .sqlite.metadata, .sqlite-journal, .sqlite.tmp PlcLogicPrefix=1 Should that not write the Application_DataLog.sqlite in the /home/pi/DataLog/ directory? Or how do move the working directory for AC_Datalog ?
I still cannot enable persistent manager for my project (and successfully login to a device). Project compiles with no errors but during download/login it fails with the fairly limited message "one or more errors occurred". The only clue I get from the system that this messages is displayed during "Generating code..: relocation pou". Any tips pointing me in a direction how to solve this very much appreciated!
I am currently having the issue that Codesyscontrol only runs for 10 seconds on my Raspberry Pi 4. I believe the problem is because the MAC address range is of the Raspberry is 88:A2:9E:XX:XX:XX. When will Codesys Control For Raspberry Pi 4.17.0.0 be released to fix this issue?

This is what is on the device, is this correct? I did not see an option to install TargetVisu, is this needed?
I have installed both the Codesys Control for Linux SL 4.16.0.0 and Target Visu for Linux 4.16.0.0 packages in Codesys 3.5 SP21 Patch2. When I try to add a target visu, it is missing. I have spent hours on this and tried different machines, all behave the same way. Is this a bug?

This is from sometime ago but below might help someone else; this could be done via POINTERS. Make sure you protect for NULL pointers etc if you take this approach. // DECLARATION myEnumValue : enumMyEnum; u8 : USINT; pmyEnumValue : POINTER TO enumMyEnum; pu8 : POINTER TO USINT; // CODE pu8 := ADR(u8); pmyEnumValue := pu8; myEnumValue := pmyEnumValue^; // dereference the pointer

I'm trying to use an fbMsSQL_compact function to read data from an SQL database. It works with some databases, but there is one database that I can't seem to get it to work on. It's set up the same as the other databases that I've tested with the only difference I see is that the name of the database is cut off in the status message. I'll get a message like "User: User logged out succesfully from database: 12345" But the whole name of the database is something like 1234567.
This solution did not give me peace of mind, so I decided to check other options again, especially since artifacts appear on some controls in WebVis. The solution is to enable the Multitouch handling option in the additional settings tab.
ich meine mich zu erinnern, dass ich schon FB's hatte, die Fehlermeldungen mit löschen des Enable/Execute Bits abgelöscht haben. Dann würde bei dir sobald das Error Bit gesetzt wird, nichts mehr drin stehen. Vielleicht wäre es ein Versuch wert, den String vor dem zurücksetzen des Execute in eine Variable zu speichern, ob dann was drin steht und danach erst ablöschen?

I had this code working in a previous version of CoDeSys to read variables from a GVL that were added to the Symbol configuration. The problem now is that when I get the _IBaseTreeNode_Parent, it returns a valid interface, but none of the methods or properties work. If you monitor the _IBaseTreeNode in the watch window, it does show the correct child count. However, it fails at step 30, where the child count incorrectly returns zero. In the image, you can see that the watch window displays the correct...

Hallo zusammen, ich habe folgendes Problem. Ich möchte mit der Lib Mail_Service_SL ein Mail versenden. Manchmal funktioniert es auch aber nicht zuverlässig. Wenn ich den Funktionsblock sendmail mit den entsprechenden Daten aufrufe bekomme ich die Fehlermeldung CHECK_RESULT_FAILD. Laut Dokumentation sollte im sServerMessage der Grund stehen, dieser ist aber leer. Was kann der Grund hierfür sein? Gibt es eine ander Lib mit der ich Mails versenden kann? Viele Grüße Micky

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...

Hi, Did you find a solution to the problem?
For anyone with this issue, you may need to: Open the text list properties (right-click the text list once you create it). Select the Text List tab. Change the Download by option to Visualization. I was fighting this for so long. Once you do that, you should find your text list appears in the drop down when editing a visualisation.
Hi, I’m currently managing over 50 PLCs running Codesys version 3.5.18.60. At seemingly random intervals, some of these devices experience a failure where: All persistent variables are lost. Attempting to log in results in the message: “The application does not exist on device. Do you want to create it and proceed with download?” The log shows: “Loading retain-data/bootproject failed.” From what I’ve gathered, this may be due to a corrupted persistent data file, but I’m not entirely sure how to confirm...

ditto I'm just getting my codesys wheels on and the modbus stuff is confusing.

I have come across this. The only way i could get it to work would be to define a word that is also the same address as the Bools. eg %MX600.0 through to %MX600.15 would be individually defined in the variables and them have another variable word defined at %MW300. You still need to break out the word in what ever program you are using to read/write the OPCUA tags.
Put %f in the "text" field and rValue in the "Text variable" field. You could also have a look at the possible placeholders: https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_placeholder_with_formatting_sequence_in_a_string.html
i want to make a frame for use multiple places for showing pressure and temperature. ive tried to decleare a variable in the frame config, if i put a fixed value in the value text field it show correct until i simulate. and if i point to a variable i gvl it show the name of the variable, and when i simulate it shows rValue. is there a way to do what i want?
