Post by tk096 on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work). In general: - Motion function blocks have to be called until they report 'Done', 'Error', 'CommandAborted' or a subsequent motion FB with BufferMode=Aborting is started in the current cycle. - Setting the Execute input to FALSE will not abort any ongoing motion of the motion function block. For example, one case that is often problematic is the execution of the Axis Halt instruction. When, after a MoveAbosulte instruction this returns the event as 'done' and indeed the axis is in standstill, the state machine first sets the move instruction to FALSE, and the next cycle sets the Halt request to TRUE. Some of the time everything works out fine. Occasionally, however, in this exchange, the axis goes into fault, also losing the OPERATIONAL state. I think the error SMC_FB_WASNT_CALLED_DURING_MOTION is only a follow-up (and misleading) error that results from the axis not being in operational state anymore (bus problems). Is there an error 'regulator or start not set' in the device log before the error 'motion generating FB wasn't called for at least one cycle'? Which error does the respective function block (Halt.ErrorId) report?

Yes, you can use the CODESYS ControlWin V3 Soft PLC. However, if simulation is enabled on the device this will disable all communication, so you need to turn off simulation to view the visualization in a web browser. In simulation mode, all IO and communication is disabled for standalone testing. In addition, make sure to set the start visualization in the WebVisu object in the application tree. I hope this helps!

Post by jarnok on How to know if output if function block is used ^{CODESYS Forge talk (Post)}
Hi, Is it possible to know of an output of a function block is used? I've found there is a way to find unused inputs of a fb, through the attribute: is_connected. But I'm wondering if the same can be done for an output. Thanks in advance!

Post by timvh on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
You have declared the function block in a function and call the instance also from a function. This is not correct, because a function is initialised with every call. The http client function block should be declared as Global Variable if you want to cal it from a Function, but probably it is better to declare it in a Program and also call the instance of the http function block from the same Program.... The variables of a Program are not initialised with each call.

Post by moksan on Unconnected_Send Explicit message with Route Path ^{CODESYS Forge talk (Post)}
I have been trying out Unconnected_Send Explicit Message with route path.(The Unconnected_Send service shall use the Connection Manager object in each router to forward the message and to remember the return path. Vol 1.3 / 3-5.6.7) However, I could not see the correct path on Wireshark. I want to see the Unconnected_Send Message Service Code as 0x52 and also the last of the message should have the route path. I want to ask some questions about this topic. The IIoDrvEIPAcylicServices Interface has the IoDrvSendUnconnectedMessage Method. And there is a struct (EIP_SendUnconnectedMessage) for this service. But there is no information about how to implement to project, and if it is successful, does it send a message with 0x52 Unconnected_Send Service Code or not? If that is not a solution, how can I set the Unconnected_Send Explicit Message struct on Codesys? Also how can I send explicit message with route path?

Post by mubeta on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Thank you for your interest. Your answers are in line with what I knew, so at least it comforts me that I did not misinterpret the situation. However, I don't have an exact match as, for this project over the past few days I have: 1) I have gone back to leaving the various FBs of the motion always called, all of them, and in the state machine I use a boolean to activate the various useful Execute. (But in the future I want to go back and try the programming technique with which I wanted to develop this project); 2) For the occasional error: SMC_FB_WASNT_CALLED_DURING_MOTION perhaps it was due to the fact that I had set the Ethercat bus synchronism only at the CAN master level, but not at the level of individual drives. I have now also activated it for the individual drives and it does indeed seem to have been resolved, but having also adopted the programming technique mentioned in point 1), I cannot say whether this was the solution to the problem, or instead the previous point. Is there an error ‘regulator or start not set’ in the device log before the error ‘motion generating FB wasn't called for at least one cycle’? I can't answer that right now. By now the machine is running and I am no longer there, at this one. Also, I seem to remember that the 'fbeFBerror' drive structure (5-element array), does not cycle, BUT ONCE THE 5 EVENTS AFTER SWITCHING ON, IT DOES NOT UPDATE ANYMORE (but that's another issue), so diagnostics were not easy.

Post by wind-11 on Problem with simulation Modbus ^{CODESYS Forge talk (Post)}
Hello everyone, I encountered a problem in the simulation while working. In a test project we set up a Modbus connection. We wanted to simulate this with test values. The connection also worked, but unfortunately the values are frozen and do not report any “current data”. (Picture attached) Since these are my first points of contact with Codesys and my colleague continues to work elsewhere, I was hoping that someone here might have an idea. Kind regards and thanks in advance.

Post by macros8 on Translation - How to get text as reference in Frames translated? ^{CODESYS Forge talk (Post)}
Hi, thanks for the link. Maybe I create elements in incorrect way. I always use Interface Editor to create variables which are used inside element (see pics). After that I place element in my visu and use Reference property to link variable or set the value. In that case the value of string is not transferred to general text list for translation as I mentioned before. Do I have to all properties which influence behavior of my element create in Frame configuration instead? What´s the difference to the Interface editor? Thanks a lot. M.

Post by joanm on Programmatically change the IP addresses of the Modbus TCP slave devices ^{CODESYS Forge talk (Post)}
Hello all, I am working in a project in which there are multiple Modbus TCP slaves. I need to be able to change the IP addresses of those devices from the HMI and I was planning to use the process depicted here: https://faq.codesys.com/display/CDSFAQ/Modbus+TCP+Slave%3A+Dynamic+Setting+of+the+IP+Address I can see the port number is what is used to specify which slave device we want to modify the IP address of. This said, can I freely set arbitrary port numbers to each device? I mean, can I set the first device to be at port 502, the second one at port 503... Any drawback or restriction? Is there any other way to reference to the device without having to change the port numbers? Thank you all in advance.

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 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?
