Hi mate, With this snippet i was able to see the lastusage variable count, but it would not iterate between clients? i was only able to access the data of the target visu. it threw an error with the array of pointers stating it was not able to convert etc. also when i tried it with the while loop it created an endless loop and crashed the program. any ideas? Thankyou

Post by amy123 on JSON Utilities ENUM to STRING ^{CODESYS Forge talk (Post)}
Hello, Is it possible to get the string returned from the ENUM JSONType? I read that with regular enumerations you can add '{attribute 'to_string'}' and access it. However, this is from the compiled library, so I can not add that attribute. When I try to use TO_STRING(JSONType) it returns the integer as a string. Ex. jsonType :=TO_STRING(pJSONData^._aJSONData[i].eType); gives '8' instead of NONE Thanks!

Post by marciohogenelst on stablish CAN communication through the PC's USB port ^{CODESYS Forge talk (Post)}
I'm using Codesys v3.21SP4 on my PC via ControlWin to establish CAN communication through the PC's USB port. The software works fine. The CAN/USB converter works fine and is validated. However, there is no communication. Which folder and file should be modified to allow the CAN/USB converter to work and thus achieve the connection? Converter used: PCAN-View Information not yet processed: Access the folder: C:\Program Files (x86)\3S CODESYS\GatewayPLC\CODESYSControl.cfg Uncomment the line: Component.5=CmpPCANBasicDrv Any help would be appreciated.

Post by pernockham on Slider instance value when accessed through "execute ST-code" ^{CODESYS Forge talk (Post)}
I have a time which I want to modify with a slider. I have confirmed it is possible to set the value of the slider by to_real(time) (I can see that the slider changes according to 'my_time_value's value). Slider variable: to_real(my_time_value); However I fail to access the current slider instance value when I want to write back the value as time (write to a variable will not work as I need a type-conversion before assignment). my_time_value := to_time(slider-instance-value); I tried with this^.? but could not see anything interesting and also THIS^.GEN_Instance.? but nothing resemble what could be the sliders value. Anyone that knows? Thanks!

Post by pernockham on How to manage soft container licenses for (remote) multi units? ^{CODESYS Forge talk (Post)}
Using Codesys runtime for Linux and thinking of the process of preparing multiple such systems for my customer. I don't necessarily have physical access to these units, they can be (very) remote. The idea so far is to use an image to install the Linux OS and codesys runtime. Application updates can be done by distribution of the PlcLogic/Application/application.app and application.crc files. But whats the most practical way of managing the license for these units? Do each controller need to be physically connected to a License Manager instance or can licenses be distributed by means of a license file for each unit? I believe that the license should be stored in soft containers for each unit. Help and insights appreciated! Per

Post by valec on Connect local Asem HMI runtime to local Codesys Control Win V3 x64 ^{CODESYS Forge talk (Post)}
I have a project made on a PL700 PLC with Codesys and an Asem Premium HMI panel. I don't have access to the physical PLC right now, so I'm trying to use Codesys Control Win V3 x64. I created the application and loaded "Codesys Control Win V3 x64" without errors, then I activate "Start PLC" from the tray. Asem cannot connect. I tried to use "localhost" or the local IP address and it doesn't work (it's the "CoDeSys Soft PLC Communication Driver"). I need to connect my local Asem runtime to a virtual Codesys application on my PC. How can I do it?

Post by tecnocons on Trouble Writing Files to External Paths in CODESYS ^{CODESYS Forge talk (Post)}
Hello everyone, I'm encountering an issue in CODESYS regarding writing files to external paths. Despite correctly configuring the placeholder in the CODESYSControl_User.cfg file to allow access to an external folder, CODESYS doesn't seem to write any files, and no errors are reported. The issue on the older versions was absent with no placeholders. I've checked the operating system permissions, and they seem to be in order, but the issue remains. Has anyone faced a similar situation or has any suggestions on how I might resolve this problem? Any help would be greatly appreciated. Thank you in advance for your support. I'm using raspberry PI as a logger. RPI3 Buster Codesys 32bit SL V4.11 Codesys Win64 3.5.20 [SysFile] PlaceholderFilePath.1=/home/pi/scan, $SCAN$
