codesys is in hex and starts at 0 your other program is set to decimal and maybe starts at 0 or 1, I can't tell.

Post by davidmic on What is this ST syntax? ^{CODESYS Forge talk (Post)}
I found some structured text code which contained this statement: bHidden:= TRUE(*NOT _somevariable*) I haven't seen TRUE() used like a function before, and I also haven't seen the enclosing asterisks * * before. What do they do? (sorry if this is a duplicate question, I don't know what words to use to search for this syntax)

https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_st_comment.html it is a comment. I guess it used to be NOT _somevariable and someone want it to always be true.

Hello Everyone, I have 5 images with same position in the screen. I would like to pass around them with giving an GlobalIndexImageId how can I do it. In properties part I don't understand the which one is doing that. Best Regards

Post by z870623 on About CPU Loading ^{CODESYS Forge talk (Post)}
I am running a runtime environment on an ARM A35 dual-core processor (1.5GHz) and have encountered some issues. The CPU load (both CPU0 and CPU1) occasionally spikes above 50% before returning to normal, and this happens around 2-3 times per minute. At the same time, I’ve noticed that the Max Cycle Time in the Codesys monitoring screen shows much worse performance compared to the A53 (1.2GHz), with nearly double the cycle time. The optimizations I have made so far are as follows: Set the CPU to performance mode. Isolated CPUs: CPU0 is dedicated to running Linux services and the runtime itself, while CPU1 runs the EtherCAT task and the MainTask. Despite CPU1 only running these two tasks, the utilization still increases above 50%, which I find unreasonable. Additionally, I performed tests using cyclictest both without and with the runtime running. The performance is shown in the following image: From the results, I believe the CPU performance should be fine, but I am unsure why the monitoring results are not as expected. The testing outcomes should ideally be as close as possible to the cyclictest results. Does anyone have related solutions to this issue?

Hi all, in the online help it written, that array of reference to data type is not possible. Ok... but if I create array of struct of reference to - everything works fine - please see the screenshots: and it works this way OK. Is it intention or error in compiler 3.5.18.20 and we should avoid it? Thanks a lot, Jan.

Hi all, I’m new to codesys and working on some project. Codesy 3.5 V20 patch 3 Every time I try to use refactor codesys hang and not respond. I was trying to use repair function in installer but this is not helping at all. Wonder if anyone experience this behaviour? Sometimes I have Popup saying : Cannot insert ‘CreateTextFile’ bellow ‘<root>’</root>

I updated the Codesys version from “V3.5 SP20” to “V3.5 SP20 Patch1” and that solved the problem.

Post by mondinmr on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Good day, I’m writing this message out of frustration regarding the current way project files are saved as encrypted XML and single-file format in CODESYS. I find this approach to be quite tedious for several reasons: Limited Access to Structured Text: Not being able to access Structured Text (ST) externally makes it impossible to work with alternative editors like VSCode. Tools like VSCode are incredibly responsive and feature advanced systems such as GitHub Copilot, which would be a real game-changer when working with ST IEC. While CODESYS works well for small code snippets or debugging, when the codebase grows, switching to VSCode to boost productivity becomes essential, and copy-pasting between environments is a cumbersome workaround. Poor Integration with Git: This file format also makes it very difficult to integrate effectively with Git. I have tested the internal demo, but for advanced merges, it is unusable. Without properly formatted plain text, it’s impossible to leverage the vast ecosystem of external tools around Git that allow smooth merges in heterogeneous teams. File Corruption on Network Drives: I often work from multiple locations with shared network drives. When the development environment saves a file and something goes wrong midway (which can occasionally happen when using VPNs and network drives), the entire project becomes irrecoverable. There’s no way to cancel the save process, and the development environment freezes. This has happened to me at least four times over the past two weeks, and one of those incidents cost me an entire day of work. All of this is particularly disappointing because I truly believe that the libraries, runtime, and overall work done by CODESYS are exceptional. I find it fantastic that there is a platform allowing development of PLCs and control systems using OOP, which is a huge advantage in modern control engineering. I apologize for the rant, but this issue has been extremely frustrating. Best regards.

Post by jarnok on How to know if output if function block is used ^{CODESYS Forge talk (Post)}
Hi, Is it possible to know of an output of a function block is used? I've found there is a way to find unused inputs of a fb, through the attribute: is_connected. But I'm wondering if the same can be done for an output. Thanks in advance!
