Post by installwhat on raspistepper error after install ^{CODESYS Forge talk (Post)}
I've had issues getting the raspistepper installed, all due to errors upon installation. The closest I get is the pictured error. The functions are in the sm3_shared library. I can add this library but that leaves 2 issues. I don't actually know, and I really want to understand this, why the required dependencies haven't been installed correctly. If I add the library it's only available with through the namespace. What can I do to both understand and resolve this? Thanks edit codesys 64 3.5.20.0 - same error on other versions too sm3 raspi stepper 0.0.0.5

The generic sensor FB is for controlling the sensor via its cyclic input (PDI) and output (PDO). In this case, ifm raw cyclic input and output data are WORDs (16 bits total) The PDO data from the Buerkert unit are SINT (8 bits) In this case, I would use the unpackword fb from the CAA memory library to unpack the valve feed back value into the appropriate location.

Post by alex2 on Codesys SVN ^{CODESYS Forge talk (Post)}
Hello Everyone. I have a question about the SVN module on Codesys. I am using Codesys V3.5.10 and installed Codesys SVN 4.2.5.1 but when i try to connect my SVN to codesys i have a message saying that there is no license for accessing the Url. I searched on the codesys store and it seems that "CODESYS Professional Developer Edition" is needed? Am i right? Do i also need to buy a USB key? Is there another edition but only for the SVN? I thank you in advance for your answers.

Post by timvh on OSCAT Scale_r function not working in LD 4.60 works in LAD2 on 3.5.21sp3 ^{CODESYS Forge talk (Post)}
It seems like a bug in FBD. Work-around: If you click on the small line between the box and the output variable and delete this, the variable is removed. When you then assign a variable again (Ctrl-A), then you will see that the line will be a bit longer. If you then select the previous variable, you will see that it works.

Post by jonasz on Deploy LicenseServer for Linux SL ^{CODESYS Forge talk (Post)}
Hello, I'm asking for help with installing the license server for Linux SL 4.18.0.0. When I try to install it, I get a message that the WIBUCodeMeter package is missing. I checked the package manager tab to see if the package is installed, and it is - Codemeter 8.40.7120.501. I've checked the CodeMeter Runtime on the target machine, and everything seems to be working fine. One thing caught my eye: the Device Architecture tab says "None" Please help me solve this problem.

Post by kenth1973 on MC_Phasing state explenation ^{CODESYS Forge talk (Post)}
My MC_Phasing FB was stuck in iPhasingState=1 and error output HIGH on one axis. I could manually overwrite the state to 0 in the instance data. During normal run I see the state change from 0 to 10 to 100 back to 0 (maybe more states that I couldnt catch with the naked eye) But - what are the states numbers and their different explenations? This is not explained in the FB guide on codesys. (the pictures show state = 0 after I reset)

Post by ara32 on CODESYS 4 Linux: ^{CODESYS Forge talk (Post)}
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?

Have you looked at this? https://forge.codesys.com/prj/codesys-example/element-collect/home/Home/ It's not exactly what you're looking for, but I've been able to make some things work more efficiently using this library.

I believe the reason that I eventually lose my ability connect is because of exceeding the time limit for demo mode. Still unsure why I cannot update the edge gateway though.

Thanks very much for the explanation. I am basically new to the rpi world, but somewhat familiar with the indraworks/CtrlX versions of codesys. Appreciate your help.

Post by sturmghost on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
You could work around this problem by implementing some sort of "state machine". Each dialog sets a boolean variable when they are closed so you know which dialog was closed. Then you can react to this accordingly.

I solved it by creating a new element of IElement according to the ElementExample (MyElement) in the ElementCollectionsExamples project. The variables in this element can then be defined in any properties as needed.

Is this issue of idling before loading libraries resolved in Codesys 3.5.18.40 ? I am also curious about this version as there seem to be huge difference in the compiler versions which don't recognize the versions with older storage format.
