Post by sercan on Does G75 work when SMC_NCInterpreter is used? ^{CODESYS Forge talk (Post)}
When a G75 command is received in a SoftMotion+CNC project, SMC_NCInterpreter does not generate any error commands, but the command does not continue execution! There is information about SMC_NCDecoder in the documentation of the G75 command. Is this command only supported by SMC_NCDecoder? Can the G75 command be used with SMC_NCInterpreter? Forexample: G75 ; RUNNING G01 X$Settings.X$ Y$Settings.Y$ Z$Settings.Z$ ; - G75 ; - G01 X100.0 Y200.0 Z300.0 ; -

Hello everyone. I have a problem: I installed new version of codesys IDE. When I try open project in this new version, I have many errors about Visu: rectalnge/button/frame/etc does not exist. How update properly project? 20+ pages of visu pages from 100+ frames and all visu elems looks like "Error image". It is not problem of SP20->SP21. Any update has problems from visu side.

Post by gunstr on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
The problem has been resolved. Two findings are described below for future reference. The new RPi hw delivered during August 2025 has a MAC address from a new vendor series that is not supported by old runtimes. 4.17.0.0 or above is required. 4.17.0.0 does not pick up the correct architecture during installation and aarch64 has to be manually configured either in the GUI under operations or in /etc/codesyscontrol/CODESYSControl_User.cfg under the [CmpRasPi] section.

Post by alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
Dear Eschwellinger, Thank you for the response. Does that mean that the license-manager inside the Codesys-IDE does not work with this setup anymore? Because when I use this I get the notification that there is no dongle attached to the device (see picture). And If I insert the license by the deploy tool, can I then redeploy the Codesys virtual control container, or does this erase the license completely?

the TCA9548a does not work in Codesys. In Pyton this is only queried once and in Codesys cyclically. Of course you can also insert a terminating resistor in each port, then you should have no problems. I use this one: https://botland.de/8-bit-multiplexer/12723-qwiic-mux-breakout-8-kanal-modul-mit-i2c-multiplexer-tca9548a-sparkfun-bob-16784-5904422341428.html You can simply set the library to the latest version. You do not need Oscat. Do you need an example project for the BMP280?

Post by ojz0r on INT_TO_WORD function not working ^{CODESYS Forge talk (Post)}
That calculation will not work the way you expect it to. If PumpFillSpeed is limitied to 0-50 then the only whole number would be 50/50 = 1 everything else is 0.0-0.9999... and since you are using word and integer only 50 would work since there is no representation for mantissa in integer values. Declare a temporary real variable and do the calculation and then do a REAL_TO_WORD in the DRV2Speed assignment.

Hello, I need to execute "sudo" commands via CoDeSys 3.5 SP 19 P5 using the "SysProcessExecuteCommand2" function. Commands without sudo are no problem, but as soon as sudo is used in a .sh or a single command, it does not work. Command=AllowAll is entered under "SysProcess" in CODESYSControl.cfg. Nevertheless it does not work. Does anyone know what the problem could be? Greetings, Thomas

Post by kleeswi on SysFileOpen does not work after update to V3.5 SP19 Patch 5 ^{CODESYS Forge talk (Post)}
I use the function SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_WRITE, pErrorFileOpen); to open and write a file. Since the update from Codesys V3.5 SP17 to V3.5 SP19 Patch 5 it does not work anymore. I first had SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_APPEND_PLUS, pErrorFileOpen); in both versions. hFile_Test is a pointer to byte. It gives an exceptional error when dereferencing the hFile_Test pointer. Edit: I use Codesys on a Raspberry pi

Hi, Similar problem, I have license for Raspberrypi Control MC SL. It didn't work with version 4.10.0.0. I have now instaled new version 4.11.0.0. Raspberrypi Control SL. The same behavior, runtime works sometime several minutes, sometime only several seconds. The second problem is with license. There isn't available any runtime MC SL on Codesys shop, not even older version 4.10.0.0. Is it only temporarily or, MC SL will be not available more for rpi?

When I try to execute the relative move start command on FB for both the drives it is not working. However, if I add 1ms second delay between the execution of each drive it is working. Also when I change the rung order it is working for the first drive in the rung. what could be the wrong here?

Just adding some info regarding the issue above. Logged onto the project using dev3og5 user (see screenshots); appeared to be ok although when attempting to logon to the device message says 'currently not authorized to perform this operation on the device' (screenshot). If user dev3og5 has same permissions as Owner user; why would it not be authorized. I am at a loss; any assistance would greatly be appreciated. Thank you Mike

Post by timvh on Device logon problem following fresh install ^{CODESYS Forge talk (Post)}
In your project you selected the "CODESYS Control Win V3" as device, but the device you want to connect to is a "CODESYS Control Win V3 x64". Those are not the same. If you double click on the device during the network scan, you will get information that these are not the same, but that you can change the type in your project to the x64 bit type. Another option is to "right-click" on the device in the device tree of your project and select "update device" then select the x64 type.

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?

Good morning, mecke96. Exactly the same thing happens to me, although I have not done the part of executing a .py file. It only reads the temperature and the counter, but the other values are zero as in your image "no readings". I have tested the MPU6050 device on an Arduino and it works. Could you tell me if you solved it?

Post by food on Beaglebone Black OPC-UA Server ^{CODESYS Forge talk (Post)}
Man, this was a long time ago. I think the problem probably stemmed from not loading the certificates from the client and the server on the server and client respectively in the correct manner. I believe I ended up getting around it just by removing all security on the server. In the end we did not move forward with that architecture so I never had to actually fix it.
