Post by timvh on When Keyboard Key is in Hold, then Webvisu is extreme slow and latent ^{CODESYS Forge talk (Post)}
I'm not really sure what you are trying to do, but maybe you are referring to using the CmpCharDevice library? When you "open" the connection to a device, you can pass flags. What helped me is to set the non-blocking flag. I'm not sure if this is what you are referring to, but maybe it helps: dFlags: DINT := CmpCharDevice.ACCESS_MODE.O_RDONLY + DINT#4000; // see details for flags: http://linux.die.net/man/2/open, + DINT#4000 is for non-blocking hDevice := CmpCharDevice.CDOpen(szFilename, dFlags, Result);

Post by ndzied2 on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
This is a consequence of how computers store floating point numbers. 0.1 cannot be exactly represented in a computer. This is not a CoDeSys thing. Here is a link to a converter to show you the exact value that is represented when you use a REAL data type (which is a 32 bit float). https://baseconvert.com/ieee-754-floating-point If you really need to keep track of 0.1 increments. use INT OR DINT and then add 1 each time and assume that there is one decimal place.

You can try this setup: DINTVar := SHL(INT_TO_DINT (Low_Word_INT_Var),16) + INT_TO_DINT(High_Word_INT_Var);

Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
maybe this would be a better approach, then you don't have to pass the constant at all. FUNCTION fun : INT VAR_IN_OUT arr: ARRAY[*] OF INT; END_VAR VAR lower: DINT; upper: DINT; END_VAR lower:= LOWER_BOUND(arr, 1); upper:= UPPER_BOUND(arr, 1); see here as well https://help.codesys.com/api-content/2/codesys/3.5.12.0/en/_cds_datatype_array/
