Post by seler on Custom button with output status ^{CODESYS Forge talk (Post)}
Hi, Im struggle with making custom button. The idea is simple grey light bulb after touch (input var) it changes to yellow but shows output var status not switch status. So if light is physically on, switched by physical switch, bulb is also yellow. How to do it?

Post by althafu on Codesys v 3.5 to factory IO ^{CODESYS Forge talk (Post)}
I have been following the steps shown in the RealPars video to connect CODESYS with Factory I/O. The connection works correctly when I use Ladder Diagram, but when I try the same simple input–output logic in Structured Text, the simulation does not behave as expected. Has anyone experienced this issue or knows what might be causing it?

As I see from your logs I think the Timeprovider is not accurate enough in your case. Things to check - at the moment you run it on the same device? (for tesing purpose ok) I would set 127.0.0.0 as IP and set it not really to Core 0 ( many other stuff is there)

https://forge.codesys.com/forge/talk/Engineering/thread/632c29cb93/#8d94 The above comment is the best, but if you just want to see it work you can try disabling the distributed clock. It's not the right thing to do but it should resolve that error.

Post by blitz on Can't get SMC_SmoothPath to work ^{CODESYS Forge talk (Post)}
Hi @bertus I have a similar situation: just like in your case I can see that rounding works correctly only for the first element, additionally in my case on a path made of lines where I am testing this every second line is skipped. The interpolator jumps to every second iActObjectSourceNo.

When the deploy of the run time begins, an error box pops up with an unhandled exception - Index was out of range. Attached is an image of the error. I am unable to expand the complete error because the software is locked up.

Did you test this with the latest version of the CODESYS Visualization add-on? Something that you might want to test is if it works better when you disable the "Support client animation and overlay of native elements". Double-click on the VisualizationManager in your project to find this setting.

Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
Took me a while to work on this again. I testes today with a fresh setup and it works now. My OneWireCycle tasks runs for around 10seconds. I guess my mistake was that I put the cycle task for the OneWire Task to a too small number. Thx for the support!

Post by eschwellinger on NO SIGNAL ON POWER_ON FOR STEPPER MOTOR ^{CODESYS Forge talk (Post)}
Hi, how should that work? You need to download the example project and you need that structure of the project and one of the additional hardware sets https://forge.codesys.com/drv/sm3raspistepper/home/Home/ L298N or A4988, DRV8880. Important to have no GPIO in the project and have this additional tasks.

Post by josepmariarams on Limit Axis CNC Jerk using SMC_Polynomial_AbsMaxLocs ^{CODESYS Forge talk (Post)}
I am using both functions for: I override SMC_LimitDynamics o calculate the individual axis jerk on polynomial movements. LimitDynamics only controls acceleration and velocity, it's not enought to create smooth movements. To solve the problem when smothing path create loops. It seems that polynomial passes two times by the same point and smc_smooth path chooses incorrect one.

Post by dmb-fan on Hilscher cards CoDeSys Control RTE ^{CODESYS Forge talk (Post)}
Hi! I'm currently trying to make my way through this jungle... Hilscher CIFX 50E PCIe cards: DP Master + CANopen Master If I want to run these under Control RTE, do I need a master license from Hilscher for each card? Or do they run entirely with CoDeSys drivers and parameterization tools? I can’t find any clear information on this from either manufacturer. Thanks

Post by ilarioimi on Date Picker ^{CODESYS Forge talk (Post)}
Hello, I am new here and need some help. I have added the Date Picker to a visualization page. The date selection works, but the current day is not highlighted. The date and time are displayed correctly by the system, which is set by default to “VisuElems.Visu_DateTime.DisplayUTC:= FALSE;”. Is there some project setting or Visualization Manager setting that I am missing? Thank you. Ilario.

Post by danwoodlock on RPI Zero w - Edge gateway cant install ^{CODESYS Forge talk (Post)}
Hello all, First post. I recently acquired an RPI zero W from amazon, and have been using it with Codesys v3.5 SP19 patch 2. I first got it working yesterday, and after installing the runtime on the Pi, I was prompted to install the edge gateway. Installation of the edge gateway failed because of unsupported architecture, undeterred I was able to connect to the pi and program as I wanted. The issue I've noticed is that if I do not load anything to the pi overnight, I can then no longer connect to the pi and download, although I can still ping it from my pc. I found that if I power cycle the PI, I am then able to connect again, and it works as normal. I did some googling and found instances where people recommended downloading the newest edge gateway, which brings me here. Wondering if there are any suggestions, or if this is a known issue. I actually tried installing all 3 versions of edge gateway for science, but all fail with the same message. Thanks -Dan
