Hello! I managed to correctly launch CODESYS Developer Studio 3.5.17, almost all functionality works. The only issue remaining is that when connecting to a device and obtaining its public key, the NCryptEncrypt function is called, which is not fully implemented in the DLL source code, resulting in the connection not being established. Currently, the code of this function in the Wine repository looks like this: SECURITY_STATUS WINAPI NCryptEncrypt(NCRYPT_KEY_HANDLE key, BYTE *input, DWORD insize, void *padding, BYTE *output, DWORD outsize, DWORD *result, DWORD flags) { struct object *key_object = (struct object *)key; TRACE("(%#Ix, %p, %lu, %p, %p, %lu, %p, %#lx)\n", key, input, insize, padding, output, outsize, result, flags); if (flags & ~(NCRYPT_NO_PADDING_FLAG | NCRYPT_PAD_OAEP_FLAG | NCRYPT_PAD_PKCS1_FLAG | NCRYPT_SILENT_FLAG)) { FIXME("Flags %lx not supported\n", flags); return NTE_BAD_FLAGS; } if (flags & NCRYPT_NO_PADDING_FLAG || flags & NCRYPT_PAD_OAEP_FLAG) { FIXME("No padding and oaep padding not supported\n"); return NTE_NOT_SUPPORTED; } if (key_object->type != KEY) return NTE_INVALID_HANDLE; return map_ntstatus(BCryptEncrypt(key_object->key.bcrypt_key, input, insize, padding, NULL, 0, output, outsize, result, flags)); } The program crashes due to the NCRYPT_PAD_OAEP_FLAG flag. I'm not proficient in C++, but I attempted to add handling myself, and here's the result: SECURITY_STATUS WINAPI NCryptEncrypt(NCRYPT_KEY_HANDLE key, BYTE *input, DWORD insize, void *padding, BYTE *output, DWORD outsize, DWORD *result, DWORD flags) { struct object *key_object = (struct object *)key; TRACE("(%#Ix, %p, %lu, %p, %p, %lu, %p, %#lx)\n", key, input, insize, padding, output, outsize, result, flags); if (flags & ~(NCRYPT_NO_PADDING_FLAG | NCRYPT_PAD_OAEP_FLAG | NCRYPT_PAD_PKCS1_FLAG | NCRYPT_SILENT_FLAG)) { FIXME("Flags %lx not supported\n", flags); return NTE_BAD_FLAGS; } if (flags & NCRYPT_NO_PADDING_FLAG) { FIXME("No padding not supported\n"); return NTE_NOT_SUPPORTED; } BCRYPT_OAEP_PADDING_INFO oaepInfo = { 0 }; oaepInfo.pszAlgId = BCRYPT_SHA1_ALGORITHM; NTSTATUS status = BCryptEncrypt(key_object->key.bcrypt_key, input, insize, &oaepInfo, NULL, 0, output, outsize, result, flags); if (key_object->type != KEY) return NTE_INVALID_HANDLE; return map_ntstatus(BCryptEncrypt(key_object->key.bcrypt_key, input, insize, padding, NULL, 0, output, outsize, result, flags)); } Now, when calling the connection, it crashes with the error "bcrypt:BCryptEncrypt flags 0x4 not implemented." Can anyone help with enhancing this functionality or at least point me in the right direction?

Maybe try going back to step one and: Var Reg1: WORD; Reg2: WORD; Reg12: DWORD; Value: REAL; end_var // program Reg1:= 4096; Reg2:= 14884; Reg12:= (reg2 * 65536) + reg1; Value:= DWORD_TO_REAL(Reg12);

The issue s the byte order typically in this case. Can be especially problematic with floating point numbers - even more tricky if transferred with a word based protocol. It is a peasant way to try out the alternatives, dword order can be a-b-c-d, b-a-d-c, c-d-a-b, d-c-b-a where a is the most significant, d is the least significant byte. So all you need is to swap the bytes in your dword, until you get the expected result. If you don't want to mess writing code for this, I'd recommend CAA_Memory library for that: MEM.ReverseBYTEsInDWORD and MEM.ReverseWORDsInDWORD functions would definitively do the trick. Otherwise, can do like this: VAR dwIn : DWORD := 16#11223344; dwOut : DWORD; rOut : REAL; pIN : POINTER TO BYTE; pOUT : POINTER TO BYTE; END_VAR pIN := ADR(dwIn); //pOUt := ADR(dwOut); pOUt := ADR(rOut); pOut[0] := pIN[3]; pOut[1] := pIN[2]; pOut[2] := pIN[1]; pOut[3] := pIN[0]; Ugly, but does the job...

@Strucc.c: thanks very mutch. Yes, I think that was the problem. I tried yesterday a similar function, i have found: IEEE32 in REAL FUNCTION IEEE32_TO_REAL : REAL VAR_INPUT IN:DWORD; END_VAR VAR PTREAL:POINTER TO REAL; END_VAR PTREAL:=ADR(IN); IEEE32_TO_REAL:=PTREAL^; END_FUNCTION REAL in IEEE32 FUNCTION REAL_TO_IEEE32 : DWORD VAR_INPUT IN:REAL; END_VAR VAR PTDWORD:POINTER TO DWORD; END_VAR PTDWORD:=ADR(IN); REAL_TO_IEEE32:=PTDWORD^; END_FUNCTION http://www.oscat.de/community/index.php/topic,357.0.html And this works perfect. Now, the only thing that isn't clear is the libary "FloatingPointUtils, 3.5.17.0 (System)"... For me, the libary doesn't work. But the problem is now solved. Thanks a lot.

How can i swap an output in a frame ? Ive got a frame of a mixer. use this twise. I want to turn these on and of. i can Get in the frame as dwAdr_Mixer : DWORD; . as Var_IN_OUT. Then Adress as Adr(Output ) But in the frame i cant swap dwAdr_Mixer^ :-= not dwAdr_Mixer^ ;

Hello just to give more feedback the error I get is "ERROR_UNKNOWN :represents raw value of 5110" in File.DirOpen. The xDone never gets true, and I never get the listing of files (csv files in this case). In the hDir i get the value of 0 for a DWord!?

Hallo Zusammen, ich versuche die Bibliothek FloatingPointUtils.compiled-library-v3 zu benutzen. leider kommt dabei folgende Fehlermeldung: Kein Quellcode für dieses Objekt... (siehe Anhang) Wie kann ich diese Bib einbinden? Kann ich diese irgendwo herunterladen? Mein Ziel ist es ein DWORD (float) in ein REAL umzuwandeln. ICh hoffe, dass ich dies mit der Funktion HexStrToReal machen kann. So wie hier: https://gregstoll.com/~gregstoll/floattohex/ convert to float... Oder gibt es bei Codesys einen anderen Weg? Ich verwende v3.5 SP20 Patch 1 + (32Bit) Grüße Sebastian
