Post by derpaul on Official MQTT-Client: MAX_RECEIVE_BUFFER_SIZE_EXCEEDED ^{CODESYS Forge talk (Post)}
Hello, my PFC200 has run for a few month now without problems. But now it freezed 2 times a day. LEDs were green but the PLC was not reachable. After power off -> on. I found that the MQTT had an error: MAX_RECEIVE_BUFFER_SIZE_EXCEEDED. And MQTT hadn't reconnect since then. I tried a cold and a warm reset but nothing helped. How can I solve this? Regards, Paul

Post by somlioy on CODESYS Control for PFC100 SL Firmware upgrade ^{CODESYS Forge talk (Post)}
Hi We delivered a system with a PFC100 using the CODESYS Control for PFC100 SL runtime a few years back. The system has once been decommissioned and are now to be commissioned again. Back then, there were only single licenses for the runtime. Can I now upgrade the firmware and runtime without purchasing a new license?

Post by jkopicz on How can you get the active frame index from a frame ^{CODESYS Forge talk (Post)}
In my project, I have frames that I would like to read the current active index. I change the frame index using the onclick properties of a button, then change frame index. I need to do some logic based on which frame index is selected. Is there a way to read the current active index of a frame?

Hi liai, I tried it with a fresh CODESYS SP21 Patch 2 installation and SoftMotion 4.18, but cannot reproduce the compile errors. Could you please upload a project archive that has the errors? Then I can have a deeper look. https://dl.codesys.com/s/q4KcbKCcZndg6oR Best regards, Georg

Post by snhatton on How to write a for loop in ladder? ^{CODESYS Forge talk (Post)}
Hi there, little late to the party, but you could also use the ST block for in-line ST code and implement a for loop as you normally would. ST Block is super handy if you just need a small amount of in-line structured text code without creating a new POU. Hope this helps!

Post by rene2 on How can you get the active frame index from a frame ^{CODESYS Forge talk (Post)}
I think I struggle with the same issue. I tried the currentVisu variable but this is the active Visualisation. I have a dialog with a frame with frame configuration like in the picture. I would like to use the index te be used to make a button look like it's pressed/selected.

After a project is opened and I have done some changes, I want to start the build or code generating process by a python script file. After the build is done I a Windows sound/beep should appear. Anyone has an example or hint how the .py file has to look like? Thanks!

Post by siscu on Raspberry Pi: List of available example applications ^{CODESYS Forge talk (Post)}
Could this be turned into a library? I'd love for a way to have the main program call a function block method using the program's I2C_master device. I assume I should be passing the master as a variable for the function block, but I don't see how that could be achieved

I am evaluating a Toradex product for use with CODESYS. Toradex and CODESYS are partners, but using "CODESYS Virtual Control for Linux ARM64 SL" together with a carrier board "Verdin mallow" However it doesn't seem to be a soft container for licenses. So how do I install a license

Post by mascara on CloseTargetVisu ^{CODESYS Forge talk (Post)}
I need to add a button to the Visualization to close it. And create a shortcut on the Windows desktop to reopen the Visualization. This is necessary to configure, for example, a local IP address. Is this possible? What command closes the Visualization? Which program opens Visualization? System: Win10 Codesys: Control RTE V3 x64 Program: Codesys V3.5 SP20 Using only a touchscreen monitor, without keyboard and mouse.

Post by mondinmr on Jitter problems on imx8 ^{CODESYS Forge talk (Post)}
We are experiencing serious jitter issues on an ARM64 imx8. Until now, on rpi and beaglebone derivatives, and on Intel, we never encountered jitter issues unless they were already present on the device. In this case, as can be seen from the attached graph, we have excellent maximum latency. The cyclictest on the isolated core dedicated to IEC CODESYS tasks shows a latency of 37µs, with an average of 14µs. Usually, on all other devices, with an RT kernel, with the appropriate parameters to avoid frequency throttling, with properly managed IRQs, and with the disabling of large page sizes, the jitter measured by CODESYS is very close to the cyclictest latency. However, on this imx8, we are noticing a fluctuating value of +/- 300µs that seems to be added to this latency, as if something occasionally miscalculates the sleep times by exactly +/- 300µs. Two screenshoot attached. - Result of cyclictest - Jitter on CODESYS Tasks are assigned to isolated core!
