Post by francescoc on Access to the path *** is denied ^{CODESYS Forge talk (Post)}
Hello, I encountered similar problems, and it appears they were linked to certain add-ons. Resolving this issue turned out to be quite complex. However, we managed to find a solution by downgrading both the "CODESYS Communication" and "CODESYS Recipes" components via the CODESYS Installer, accessible under the "Tools" section.

Finally this solved my issue: https://forge.codesys.com/forge/talk/Engineering/thread/3da9ded84e/, and the official documentation https://faq.codesys.com/display/CDSFAQ/SysFile%2C+Persistence+Manager%2C+Datalog+Manager . Add the media folder to the PlaceholderFilePath. Like this: PlaceholderFilePath.2=/media/pi, $usb$ PlaceholderFilePath.2.View=1 PlaceholderFilePath.2.Volatile=1

Post by timvh on Limiting Memory Access of an Array to Within its Bounds ^{CODESYS Forge talk (Post)}
Add the object "POU for Implicit Checks" to your application, then select "Bounds check". This will create a function which is automatically called each time an array is write accessed. In the function you can handle "out of bounds" situations. By default it will be limited to its lower or upper bound.

Post by cihangur on Application has invalid license metrics. ^{CODESYS Forge talk (Post)}
Hi, I have a "CODESYS Control Standard L" license and I use Ethercat and Profinet in my project. The project works seamlessly with two fieldbuses. However, when I add modbus_Com (Serial) or 1 OPC Tag to the project, the program throws an exception (Application app=Application has invalid license metrics!). My license should support 10*Modbus and 512 OPC Tags. Why might this problem occur?

Which plc type is it? Easy connection is to install a Gateway on remote side - this is available for Windows and Linux devices Then just add a new Gateway in CODESYS (with the IP Adress of the remote device) -> then scan the plc via this new added Gateway

There are examples installed when you install codesys. they are located in C:\Program Files\CODESYS 3.5.19.50\CODESYS\CODESYS SoftMotion\Examples The examples won't be specific to your drive, though you haven't specified the exact drive. After you add the device to the ethercat master you can click on it and set pdo etc

Solved! Go to Control Panel -> Windows Defender Firewall -> Allow an app or feature Enable the options to change settings. Scroll down the list of applications to CODESYS and CODESYS ControlService. If you do not see this application, add it to the list. Make sure all checkboxes are checked (Domain, Private, and Public).

Post by timvh on Configuring a 2's compliment ^{CODESYS Forge talk (Post)}
You could create a DUT of the Type Union and add an array of 2 bytes + an Int. Then write the byte values in the array of the Union and read the Int. Or VAR iInt : INT; byHigh : BYTE := 2#1111_1111; byLow : BYTE := 2#1111_1111; END_VAR iInt := TO_INT(byHigh*16#100 + byLow);

Hi if you add in (ttyAMA0 should fit to your HAT's device [SysCom] Linux.Devicefile.1=/dev/ttyAMA0 to /etc/CODESYSControl_Usr.cfg since 4.12.0.0 version /etc/codesyscontrol/CODESYSControl_Usr.cfg then access in CODESYS with Com1 should do it. Keep in mind that only adapters work (for RS485) which do determine the send/receive direction in hardware

Post by climblinne on Calling OPC UA Methods from UaExpert ^{CODESYS Forge talk (Post)}
Hello, I hope someone could help me. I installed the newest Codesys 3.5 SP 20 Patch 1. When loading the demo files from @i-campbell I can upgrade them to the latest version and everthing works on the OPC-UA client side as expected (object "a" is visible, I can use the "ExampleMethod"). Now I * remove the "Information Model", * delete the "OPC_UA_Symbols Objects", * Add "Information Model" again * add "TestRootObjectType" again and "Generate IEC declarations" * and search for mapped instances (to get instance "a" again) Very good still working as expected. Now I delete the OPC_UA_Symbols and add it again referring to the "objecttest" from 16.9.2020. Also I redo the steps from above. The result is now, that I can't see the "a" object in the "Root/Objects" folder. Why ist this and how can I make it running? I think, it could may be a different version of the UA configuration file. I tried to build my own model definition files and got the same problem (but I am really not an expert). When someone has a actual model, which is also running in the actual Codesys I would be very grateful. Or even better, how to make the correct model in e.g. UA Modeler SW (I followed the description https://documentation.unified-automation.com/uamodeler/1.6.0/html/howprojnet_sec.html).

Hello, I have been using CODESYS for a while and after updating to version 3.5.18.50 the code randomly stops with this fault. Why is that ? I have tried to locate the fault in the Call Stack but I dont know what to do now... I have updated the projects properly for the version I am using. This fault started happening after like 14 days of using the new version of CODESYS.

hi! im planning a project on a raspberry with Codesys. For this I'll need a number of relays to control heating and fans, all a max of 24v and about 2a. How would i know if the board / relays i buy will be working with Codesys? Does every hat work or does it need a library/driver? is there a list of drivers/libraries created? as this is a hobby project all tips on a relay board or single boards that works with codesys and not to expensive are very welcome.

Post by timvh on When Keyboard Key is in Hold, then Webvisu is extreme slow and latent ^{CODESYS Forge talk (Post)}
I'm not really sure what you are trying to do, but maybe you are referring to using the CmpCharDevice library? When you "open" the connection to a device, you can pass flags. What helped me is to set the non-blocking flag. I'm not sure if this is what you are referring to, but maybe it helps: dFlags: DINT := CmpCharDevice.ACCESS_MODE.O_RDONLY + DINT#4000; // see details for flags: http://linux.die.net/man/2/open, + DINT#4000 is for non-blocking hDevice := CmpCharDevice.CDOpen(szFilename, dFlags, Result);

Post by mputaggio on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hello, We encountered the same issues on both recipe library versions 4.2.0.0 and the newest 4.3.0.0. The Arrays of structs get saved correctly but loading them restores only some indexes, while others get lost or completely wrong. We have been using the same recipes for the last two years on recipe manager vers. 3.5.17 withoud issues. There also seems to be a different behaviour in vers. 4.3.0.0 but it's still incorrectly loading the recipes. Did you find any workaround or solution? Codesys version used: 3.5.19.50

the TCA9548a does not work in Codesys. In Pyton this is only queried once and in Codesys cyclically. Of course you can also insert a terminating resistor in each port, then you should have no problems. I use this one: https://botland.de/8-bit-multiplexer/12723-qwiic-mux-breakout-8-kanal-modul-mit-i2c-multiplexer-tca9548a-sparkfun-bob-16784-5904422341428.html You can simply set the library to the latest version. You do not need Oscat. Do you need an example project for the BMP280?

@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

Post by miodusy on File transfer via visu and codesys automation server ^{CODESYS Forge talk (Post)}
I have a problem with the file transfer library. Namely, it does not work via the codesys server. (error 5; overtime, and visualization resets). They operate mostly in local chains. I tested different browsers and VPN from the router. It works everywhere, except through access from the codesys automation server. The client, having many machines under one account, prefers to keep it that way rather than use an individual VPN just to download a backup. Does anyone have an idea what the problem is? Sylwester M.

I am assuming that I am doing something wrong with the parent index but have tried a lot and can't get it done. Kind regards, Rob

Post by dagsupport on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
Hi everybody We are currently working on a project with an RS232 serial COM interface and using the CAA SerialCOM library. We have it working fine reading and writing data, although we have found an issue we cannot resolve and any suggestions would be helpful. We have noticed that after a while the RS232 stops working. We have tracked this down to the HANDLE hCom keeps increasing and when this reaches 1023 the COM returns an unknown error "5003". Is there a way to reset this hCom reference? Thanks Richard
