Post by rodberna on Library for arrays ^{CODESYS Forge talk (Post)}
Hi, I'm creating a program where I need to handle arrays, like: - Declare lenght variable arrays - [array(1..var) of "sometype"]. This is not possible in pure codesys, right? - Know array lenght, min, max, avg values in runtime - append/delete itens in an array - and so on Is there a library know for this in codesys. Is it possible to build our own libraries using some high level language like python or java script?

Post by mejak on Raspberry Pi USB HID RFID Reader - read ID in plc program ^{CODESYS Forge talk (Post)}
Hello, I have an RFID reader that is detected as a keyboard. While looking for information, I came across examples using visualization. I would like to read the ID without visualization or external code in python, only in PLC. I found on the forum that you can try reading directly from potru /dev/... https://forge.codesys.com/forge/talk/Runtime/thread/24b3527036/ How to read values directly in codesys? Or maybe there is another solution? Best Regards

Post by stuartjr on Webvisu IE Page Scroll Bars ^{CODESYS Forge talk (Post)}
Is it possible to get scroll bars to show when displaying a web visualization in V2.3? I've got some big pages that I can scroll around when using the in-built visualization but when they are displayed in IE i can't seem to scroll around. All I can do it drag the window bigger onto my other display to get access to the extra area. I've also tried zooming the page out in IE but this doesn't seem to work at all.

Post by bartg on Open a POU in the editor via scripting ^{CODESYS Forge talk (Post)}
Hi, I would like to automate opening some specific pous and visualisations in the codesys environment I found out that I can open it by using : system.commands["42f6acb9-bd6e-42e7-94bb-6e2a03973b83"].execute() But the POU has to be selected in the Devices or POUs navigator. Does anyone know how I can select a specific POU in the navigator? Or how I can open a specific POU? I can retreive the guid of the POU. Thx

Post by sajid on NMEA Serial data read in Control win v3 x64 ^{CODESYS Forge talk (Post)}
I am using the SerialCom example program from the CODESYS website to read NMEA strings in CODESYS Control Win V3 x64 through a serial-to-USB converter. However, I occasionally receive only partial data or encounter errors in the received string. A screenshot of expected NMEA string attached for reference. Could you please advise on how to ensure the full NMEA string is received consistently? Error in strRead variable is <value of="" the="" expression="" cannot="" be="" retrieved=""></value>

Post by cmj-icsys on Custom configure tab in device editor ^{CODESYS Forge talk (Post)}
Hi everyone, I’m developing a custom CODESYS I/O driver for my company’s device, and I’ve been studying the example projects in CODESYS V3.5 SP20 Patch 5. In the IOMappingExample.project, I noticed that EtherCAT devices provide additional configuration tabs in the Device Editor, such as General, Process Data, etc. However, for custom I/O driver examples (based on IoDrv), the Device Editor only shows the default tabs like <devicename> I/O Mapping or <devicename> Parameters.</devicename></devicename> I’d like to create custom tabs or configuration pages in the Device Editor (e.g., “General Settings”, “Communication”, etc.) to allow users to configure parameters in a more structured way. Could anyone explain: How to define and register custom tabs or UI pages in the Device Editor? What tools or SDKs are needed to create UI elements such as combo boxes or check boxes? How to bind those UI controls to device parameters defined in the XML (device description)? Any example, SDK reference, or documentation link would be really helpful. Thanks in advance!
