You can definitely pull the actual system time into CODESYS without too much trouble. Take a look at the SysTimeRtc or SysTime library—both let you read the current date and time from the Raspberry Pi. You can call SysTimeRtcGet() or SysTimeGetTime() in your PLC code and then format the hours, minutes, and seconds into variables that feed your 7-segment visualization. Once you’ve mapped those values, your Visu display will update automatically each cycle. It’s a pretty common approach for clocks in CODESYS, so you should be able to get it working quickly. golf hit

Hi, based on your description (device reachable via ping but Geometry Dash connection actively refused), it sounds like the issue is likely not network-level but service-level on the target machine. Which port is Deploy Control SL trying to connect to? Have you confirmed it is open and listening?

To display the current time, you’ll need to retrieve it from the system clock. In CODESYS, you can use the built-in function SysTime to get the current system time. Here’s an example of how you can use it: VAR dtCurrentTime: DATE_AND_TIME; sTime: STRING(8); END_VAR dtCurrentTime := SysTime(); sTime := TIME_TO_STRING(dtCurrentTime.t); The sTime variable now contains the current time in the format “HH:MM:SSuno online".

Hello, I made this configuration, I'm moving the encoder value to SM_Driver_PosControl.in.wActPosition. When I make the absolute movement of my PosControl axis, my physical drive axis rotates perfectly, but I noticed that the movement is not followed by the encoder. That is, if I hold the encoder and keep it in position 0, the PosControl axis makes the absolute movement of 314 mm and stops, which is strange because the encoder is at 0. Theoretically, the PosControl axis should accelerate to try to compensate for the movement error. I haven't yet achieved perfect functionality.

Hello, im using dynamic memory allocation with the NEW()-operator. When i instanciate a class with the NEW()-operator and want to debug/watch the interface of the class, the watch is only showing "Hidden Instance" (See attached screenshot). Is there any possibility to debug the interface data ? The interface is working properly but the debugging by the watch is not possible, what is a big disadvantage. Thank you. Best Regards, Alexander

Post by lukasz on Unresolved reference when trying to upload to Codesys Runtime V3

Hello! I'm working with Codesys SP21 Patch 4. The project builds without any errors. When trying to upload my project to Codesys Runtime V3 x64 I get a lot of Unresolved Reference errors, all with FU- at the start and then -CLOSELAYER2, -GETBUSINFO, -GETFRAME etc. I also get a error pop-up that I should 'update device' in the project but it's not specified to which version or anything useful really.There's also not much to choose from. When I check Runtime version in the systray I get 3.5.21.40 and it's the same as I have set up in the project as the device. All information I get is that it should be clear from the errors but no useful information is provided in the errors. Do I need to install some library? I checked other posts and for different reference error and this was the answer. Thanks in advance!

Post by tommyk-mar on Smooth path is not working with SMC_NCInterpreter
CODESYS Forge
talk
(Post)
Hello, Im using SMC_NCInterpreter and SMC_NCReadFile2 to read gcode program for CNC machine and what I have observed is that G51 and G52 is not smoothing the path. Machine stops in every point, what could I do to make machine pass through the points without stopping or what could allow me to use smooth path corretly if I use NCInterpreter. Im using it because I want to add variables to my gcode and its not possible directly from the CNC editor thats why I do use external file. Any ideas?
