This is not possible. Possible solution could be: CASE var1 OF 10: CASE var2 OF 10:; 20:; END_CASE 20: CASE var2 OF 10:; 20:; END_CASE ELSE ; END_CASE

Thanks for the information, I ended up just making a long if else statement as each variable had 3 possible options, I figured at least this way it would still work.

Hi, again after spending a lot of time finding more information with no results, by chance I changed the device ID from 1 to 255 and the transmission works. Unfortunately the documentation is very very poor.

Hi, no guarantee, but this should work with Bipod_Rotary (https://content.helpme-codesys.com/en/libs/SM3_Transformation/Current/SM3_Transformation/Function-Blocks/Positioning-Kinematics/Parallel-Systems/Kin_Bipod_Rotary.html), with dDistance = horitzontalDistanceTop-horizontalDistanceBottom.

Post by mubeta on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
CoDeSys 3.5.19.7 Target Berghof MX6 In a simple SoftMotion programme with two stepperless modular axes from CMZ, one is simply controlled in speed, but a spot must perform a positioning. I use the function MC_SetPosition() both to reference the axis at power-up and also to correct the actual position to a fixed machine reference detected with proximity. The function has only one instance and I actually use a booelan variable to control the ‘Execute’ input. Well, I cannot correctly change the axis position on the fly if it is running at high speed. The servomotor works in a speed range between 0°/s and 720°/s, (gearbox output with a 1:6 ratio). As long as the servomotor is operating at speeds below about 400 °/s, the function is able to correct the position correctly even when forcing values far apart, but at high speeds, from 400 °/s upwards, the correction no longer takes place. For example, trying to correct the position of 280° into 300° with absolute mode, the axis that is moving at speed actually shifts the position by a few degrees, not the expected 20. I don't understand why with the servo drive running slowly the position shift occurs correctly, while increasing in speed it no longer works.

How is that possible to put a Function Block Method in the Task Configurator, as they did in the CNC3DEditor.project example? In that exmaple, I removed the gCNCMachine.SlowTaskCall method from the Task Configuration and I can't put it back. https://us.store.codesys.com/cnc-3d-editor.html Thanks!

Hi, have the same problem. Tried various versions (3.5.17.0 3.5.18.5 3.5.19.0 3.5.20.1) When you compare two functions blocks inside one project, the compare function does work. Regards, Gerco

Thanks, but unfortunately it does not work. I tried also the other function in the Properties window. What i tried also is to change the Visu-Style or looking for options.

You can use function blocks like TCPServer to start the Retro Bowl College server and TCPAccept to handle incoming connections, with CAA.Handle simply acting as a reference ID for each resource.

Post by tk096 on SMC_ReadNCFile2 is always busy ^{CODESYS Forge talk (Post)}
Hi, do you process the sentences subsequently? If not, the function block fills the sentences (queue) and waits for the sentences to be processed, so that new sentences can be read and filled to the queue.

Hi nano, thanks for your answer, it took me some time but finally it works - the make file provided by the SDK takes care of practically everything :)

Update as of 2025: This function (IECStringUtils.FormatDateTime) doesn't make any sense there isn't any parameter that accepts a Date_Time value. I have no idea what's purpose even is. I am going to use StuSprintf from the StringUtils library for this purpose.

Post by joanm on Function block method default arguments ^{CODESYS Forge talk (Post)}
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 eschwellinger on function block output ^{CODESYS Forge talk (Post)}
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.
