Post by pazderai on CanOpen write issue ^{CODESYS Forge talk (Post)}
Thank you for an answer. Unfortunatelly, it doesn't work. The slave needs command byte as follows 0x22. It means expedited transfer where s-bit is not set, therefore data length is not specified. If I use segmented mode by CiA405.SDO_WRITE_DATA it produce command byte as follows 0x21 which is unfortunately supported by the slave and it returns with error 0x05040001 - SDO Abort Code -Client/server command specifier not valid or unknown. I can use CAN API low level to overcome this problem where it is possible to set 0x22 as a command byte, but than I can use user interface to set the communication probably, because I thing that machine expert uses library CiA405.SDO_WRITE for setting the slave. Or am I wrong?

Post by pernockham on How to manage soft container licenses for (remote) multi units? ^{CODESYS Forge talk (Post)}
Using Codesys runtime for Linux and thinking of the process of preparing multiple such systems for my customer. I don't necessarily have physical access to these units, they can be (very) remote. The idea so far is to use an image to install the Linux OS and codesys runtime. Application updates can be done by distribution of the PlcLogic/Application/application.app and application.crc files. But whats the most practical way of managing the license for these units? Do each controller need to be physically connected to a License Manager instance or can licenses be distributed by means of a license file for each unit? I believe that the license should be stored in soft containers for each unit. Help and insights appreciated! Per

Post by dkugler on Codesys SVN ^{CODESYS Forge talk (Post)}
Don't set on SVN. The service phase has started in March 2024 and will be discontinued in 2027. We actually use SVN and have to switch to GIT in the future. As I informed, there is no way of getting a single SVN or GIT licence. I' dont understand, why Codesys forces us customers to pay for an expensive Professional Edition paket from year to year using only one part of it! If you find a way to buy a single licence, let me know.

Post by ranadheer on Implementation of IEC-104 ^{CODESYS Forge talk (Post)}
Hi Everyone, As we didn't have client for IEC - 104 - only server server is available , so because of that we are trying to make establish the communication between the external simulator as a Client and codesys itself as a server. We are looking for the variable behavior from CODESYS has to change according to the message triggered by the CLIENT (we are using simulator Application like Redisant). We are able to see the log data as the status of triggering the SCS from Client received to the Log data of the codesys device(attached screen shot of it) and in simulator panel we had set the details to trigger the data from Redisant to Codesys. Current Status: The project builds and runs successfully, but I need guidance on how to connect this to an external IEC-104 simulator for testing and visualization by using demo mode.

Post by alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
Thank you for your quick response, I have updated to the 4.17.0 (Virtual control and the license server). Now I am able to see the softcontainer from the Codesys IDE. But when I want to activate the license I get the following message: Licensing info not available. The device does not support this service (See picture). I then tried to active it via the WBM service like you suggested. But when I try this is get an error (see picture for error). I also tried to put RTS- in front of the serial number, but when I try this I get an error that the serial number is not correct. I think I'm getting closer, but I'm not there yet.

Post by ofey on Modbus TCP communication ^{CODESYS Forge talk (Post)}
Hi! I tried setting up the PLC I'm working with (Beijer GN-9373) to connect to a modbus master running on a laptop. I have an ethernet connection (via USB-C to ethernet) between the laptop and the controller. I have tried following tutorial on how to set this up. I have added an ethernet device with the IP-address of the PLC. Further I added a ModbusTCP_Slave_Device with default settings. I get the error "Failed to open TCP Port: 1" when I try to go online with the PLC. Earlier I tested the exact same set up with the soft PLC from codesys. I can then read/write values correctly with the Modbus master i have running on the laptop. Hope anybody can help me with this, thanks in advance!

Post by ulvis on CFC Pages Cut&Paste is not working at its best ^{CODESYS Forge talk (Post)}
In the CFC page oriendted editor, if I copy some elements consisting of an input connector, some connected logic and an output connector and then paste this on a another page then the pasted elements get inserted with an offset to the right so that the rightmost connector falls outside of the page, in the grey hatched area. So far so good. Then I mark all the elements and try to drag them into the correct placement, collectively. THIS IS NOT POSSIBLE! I only get the "forbidden" icon tooltip. One has to drag & drop the INDIVIDUAL elements to move the elements around. What am I doing wrong?

Post by timvh on STRING conversions to DWORD ^{CODESYS Forge talk (Post)}
I guess that the printer expects to receive an array of byte values. So where it is described that it expects to receive: Hercules String : 1B4F513030311B7532626C61636B04 it actually expects to receive an array of bytes with the values 1B,4F,51,30,30, etc. So what you can do is create an array of bytes and assign the byte value to each item in the array: VAR abyToSend : ARRAY[0..99] OF BYTE; END_VAR abyToSend[0] := 16#1B; // ASCII Escape character, hexadecimal representation uses 16# as prefix abyToSend[1] := 16#4F; // ASCII 'O' abyToSend[2] := 16#51; // ASCII 'Q' abyToSend[3] := 16#30; // ASCII '0' // you can do the rest yourself // maybe could be created a lot smarter, but gives you an indication how to handle this. Then with the serial communication (or TCP/IP?) you can send a message with the reference to the array (abyToSend) and the number of bytes to send (15 bytes for the string you gave as example).

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?

Post by fdmartello on Unable to compare projects containing alarm manager 4.5.0.0 ^{CODESYS Forge talk (Post)}
Hello. In Codesys version 3.5.19.50 when comparing two projects that have an "Alarm Configuration" obj from the Alarm Manager library vers. 4.5.0.0 the attached error pops up. This originally happened with two projects that I converted from vers. 3.5.17.30 so, thinking it was some conversion issue, I created two clean projects directly in 3.5.19.50 using the Standard Project template and only added the Alarm Configuration objects in them. The result is the same and the only way I found that allowed me to compare them is by deleting the incriminated object in one of the two projects. Has anyone else encountered this issue? Best regards
