Post by gesc on Unable to compare projects containing alarm manager 4.5.0.0 ^{CODESYS Forge talk (Post)}
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 :)

Post by bnewman on IECStringUtils.FormatDateTime ^{CODESYS Forge talk (Post)}
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.

Hi Lamine97, if you are struggling with the LD implementation it would be more helpful for us to see that code in a screenshot.

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).

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.

Post by apurv on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
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.

Post by dkugler on Ramp function ^{CODESYS Forge talk (Post)}
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?

Post by fcmtw on SDO generation ^{CODESYS Forge talk (Post)}
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 ?
