It's probably because you have an INT in the input to the MUL function, which will then try to output an INT as well. INT variables can only handle values of -32768 to 32767. Your value of 523000 won't fit in an INT, so it turns into an invalid number. Use a DINT. This is usually better for working with time values anyway, because time values are all 32 bit. Or if you can't, use INT_TO_DINT(gvlp.detectie_nalooptijd_s) in the input to the MUL function.

This works for me in Schneider Machine Expert 2.2, which is based on Codesys 3.5.19. It did not work in Machine Expert 2.1, which was based on Codesys 3.5.16.

you might have some slight inaccuracies with using a REAL. See here for an explanation: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019ZSMSA2&l=en-US It might not matter, depends on how accurate you need it. I usually stick with integer types for something like this

thnx, meanwhile I added a INT_TO_REAL, now it works. Can I leave it like this or better DINT ?

The new TwinCAT 4026 will add those default parameters, as TwinCAT drinks from Codesys I guess that will be implemented soon (or maybe, it already is given what tvm says in the previous post).

Post by jmohre on External file with relative path ^{CODESYS Forge talk (Post)}
I try to add a simple text file to my PLC application, so that is download everytime the application is downloaded to the target. What I did is to add an external file to the application and this works perfect as long as the external file location does not change. It looks like the external file path is stored absolute in project. But if different users work on the project they may have different locations where for their working directory. Is there an option to store the external file path relative e.g. to the project file? Or does s.o. know a different solution to add a text file to application in order to download automatically with the application? Thanks

So none of the images from the 64bit archive work with any Codesys Control versions? I have tried the last Pi OS with every Codesys Control version and they don't work. I was wondering if there's any stable combination of versions.

Hello Mr. Schwellinger, why is there no release note at a central point with such incompatibilities? I also wasted a whole day until I found this thread by chance. best regards Andreas

Post by vformanek on irq-set piority is not working in plc-shell ^{CODESYS Forge talk (Post)}
Hello, I am currently having issues on CODESYS Control for linux SL with DTH expiring. I have followed several tutorials of creating a proper RT linux. Then I further configured the linux based on this tutorial: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_performance_optimization.html Currently I am getting DHT expires in the communication and I am trying to increase of the priority of the network task which manages the PROFINET network adapter. I am following this tutorial: https://content.helpme-codesys.com/en/CODESYS%20PROFINET/_pnio_trouble_connection_failure.html But the irq-set is not changing the priority. See the image bellow....

Post by anderson on function block output ^{CODESYS Forge talk (Post)}
I'm trying to make a CNC machine, but I'm having problems because the drive I'm using only has the option of communicating through digital inputs. In this case, I should use the CLP's digital outputs to communicate with it, correct? However, in the function blocks it seems that they are already pre-programmed and I didn't find the pulse output options, for example, so that I could associate a digital output from the PLC to connect this to the drive's pulse input. My question is: is it possible to associate the pulse output of the function block with a digital output of the PLC? and how to do this?

Post by spiessli on Softmotion axis to CANopen Maxon IDX drive ^{CODESYS Forge talk (Post)}
Hi, I want to use Maxon IDX drives for some simple robotic applications. I have used Maxon's Epos for generating a DCF file to import in Codesys (attached). Then I can add the IDX motors under a CANopen manager in the device tree. Unfortunately, I cannot add a "softmotion axis" to the IDX motors. Now I am wondering, why? Without being able to attach a softmotion axis to the device in the device tree, the use of the motor is greatly reduced... spiessli

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hello, according to Codesys, the problem should be solved with version 4.3.0.0. After the update to version 4.3.0.0 I had the problem that the recipes weren’t saved correctly, but loading was okay. Return to the version 4.2.0.0 didn’t change the behavior. Strange… So I uninstalled the update, cleaned the project and built it new. The known behavior of version 4.2.0.0 was back. Update to version 4.3.0.0, clean and build it new, it works. Even with version 4.2.0.0. Strange, but okay. Notice: ManCommands.LoadRecipe() no longer writes into the PLC. Just as it should be. As of now, I can use the new version.

I think you should use a piece of hardware in between your drive (pulse/direction) and the plc like for example Beckhoff EL2521 - so Ethercat might be to choice if you need CNC and SoftMotion. EK1100 and EL2521
