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

Could not find the solution to this issue but I have side stepped this by creating a global variable MAX_SIZE.

okay but will this pass the array by copying it or it will be a reference to original array only.

not sure on which plc you are - there might be the option with: https://forge.codesys.com/drv/sm3raspistepper/home/Home/ but it is more or less Pi restricted and need additional hardware too I guess.

The util.RAMP_INT and util.RAMP_REAL from Codesys have an input for the start value. What is the advantage of this OSCAT ramp instead of the Codesys util lib?

Thank you seoerr for your suggestion. When I implement that line, I get this error: ** [ERROR] 'OSCAT_BASIC.ARRAY_SDV' is of type FUNCTION and cannot be instantiated** Any other thoughts about instantiating these sections of the library which seem to be provided as source only?

Thanks for the answer. So yes I've enabled expert settings, and yes i've added some SDOs, but some of them who are generated are likely making a mess in the network and generated error with my device... From which library comes those 2 function blocks ?

Solved: I started from a fresh project and everything worked. I had a Function Block in the project at one point and deleted it. I think Codesys doesn't fully clean up on deletes.

Which plc type is it: Either use Automationserver to do this or save the project archives instead of projects or use the source dowload function and reopen the application from plc. So you need to chose one of them.

you try to convert a WORD with BYTE_TO_HEX directly? Using https://de.helpme-codesys.com/ lead to the SM3_shared lib. There is a function: https://content.helpme-codesys.com/en/libs/SM3_Shared/Current/SM3_Shared/StringFormat/Word_To_HexString.html

You can use the R_TRIG and F_TRIG function blocks to generate a pulse in Rising or Falling edge of your signal. Have a look here: https://content.helpme-codesys.com/en/libs/Standard/Current/Trigger/R_TRIG.html

Post by grant32 on RAMP_REAL FB is retaining my output value when i try to re use the FB ^{CODESYS Forge talk (Post)}
Hello, I'm relatively new to PLC programming. I am trying to creat a ramp down function, I have an example here of what I am using. I can get the function to work, the issue is that the OUT (variable3) value is being held by the FB so after I use it once it no longer works. In this example i set variable3 to 100 and the rest is as seen, over the course of a minute it ramped down to 10 (as desired). But when I deenergize TEST_START, set variable3 back to 100, and then re-energize TEST_START it immediately jumps back to the previously held value 10. The reset on this block just pauses the function and holds the last OUT. In my case I will need the function to start OUT at a set value, ramp down to the IN (variable2) value, and then accept a new OUT value to ramp down next time the block is energized. Hopefully this made sense, if anyone has any advice that would be awesome!

Try OSCAT_BASIC and Function DW_TO_REAL. DWORD_OF_BYTE my although help. The Lib is open and free. It is not necessary to add this Lib, you can use/copy the source code just to get an idea.
