Codesys has a motion libraries (SoftMotion), but you need to buy a licence keys for them to work. the most basic one is SoftMotionLight. you just have to select your drive in the device view and add a SoftMotionLight CiA402 axis. then the library is added to your project. You can use the SML_* motion FBs and configure the axis now.

Post by wind-11 on Simulation Modubus ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich bin über die Arbeit auf ein Problem in der Simulation gestoßen. In einem Test-Projekt haben wir eine Modbus Verbindung aufgebaut. Dies wollten wir mit Test-Werten simulieren. Verbindung hat auch funktioniert, jedoch sind leider die Werte eingfrohren und melden keine "laufenden Daten". (Bild im Anhang) Da es meine ersten Berührungspunkte mit Codesys sind und mein Kollege an anderer Stelle weiter arbeitet, hatte ich gehofft, dass vielleicht hier jemand eine Idee hat. MfG und schon jetzt ein Danke vorweg.

One workaround is to create a second application which is started after the rested of the main application. The second application starts the main application after time x and is rest after done start of the main application. No problems during the fieldbus re-start by this workaround.

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 clabaldo on Open dialog from ST previous to version 3.5.16 ^{CODESYS Forge talk (Post)}
I have found a similar topic but tried to run it in C3.5.16 and the visualization crashed. https://forge.codesys.com/forge/talk/Engineering/thread/8be0f6f14a/ My question is what is the easiest way to run a dialog from ST, as we need an external device to open the dialog so we cannot use the button on the display itself.

Thank you very much Florian The SoftMotionLight package is actually more expencive than the normal SoftMotion. What is exactly the difference? Does my PLC need to be compatible with SoftMotion or does this work with any PLC?

Hello That's certainly CiA402. I'll attach a part of the manual for my servos, but the state diagram should be the same at yours. To be sure, get one from your manufacturer. Look at the bits in the StatusWord to see where you are in the diagram, then twiddle the bits in the ControlWord to get you to the next step. Then there are other bits in the StatusWord to tell you 'InPosition' and things like that. From the screenshot, as it mentions only 'PositionProfile' the driver will create the motion profile. So you need to put a target position in here - there should be profile velocity somewhere? Possibly, you need to write these with SDO's? At the minimum, you need to write a value to 0x6081, 0x6083 and 0x6084 (velocity, accel, decel)

Post by tk096 on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge talk (Post)}
Hi, under this circumstances the performance of a Raspberry Pi 4 should be sufficient to run a Softmotion robotics application. A closer look at the project would be required. Maybe you could contact the codesys support? Usually it is recommended to run the planning task cyclically every 2ms with task priority of 0 on a dedicated core. In the task configuration you can have a look at the average and maximum execution time of the planning task. You could use the function block SMC_TuneCPKernel (https://content.helpme-codesys.com/en/libs/SM3_Robotics/Current/SM3_Robotics/POUs/AdministrativeConfiguration/Computation/SMC_TuneCPKernel.html) to define suitable values for the parameters 'fSyncBufferDuration' and 'fPlanningInterval'. However, as previously mentioned, the performance of a Raspberry Pi 4 with realtime patch should be sufficient. The 'fPlanningInterval' parameter specifies the maximum planning step width in seconds. The cycle time of the planning task should not permanently exceed this value. A higher value reduces the computational effort, but can lead to a violation or no full utilization of the set limit values for velocity, acceleration and jerk. From a starting value of 0.016 seconds, the value should be increased gradually until the performance is acceptable. The parameter 'fSyncBufferDuration' specifies the size (in seconds) of the buffer between the planning and fieldbus task. The cycle time of the planning task must not exceed this value at peak times (this will lead to the error SMC_CP_QUEUE_UNDERRUN). A higher value can compensate for peaks in the cycle time of the planning task. At the same time, however, this also increases the latency for executing interrupts and aborting movements.

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?

Hi, thanks a lot for the response. I did check all these parameters, but if the PlanningTask takes up to 60 ms, I can't increase the Buffer to such values. I contacted the Codesys support with a projectarchive. Let's see if they can help. Thanks again for your great support!

Post by dagsupport on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
Hi everybody We are currently working on a project with an RS232 serial COM interface and using the CAA SerialCOM library. We have it working fine reading and writing data, although we have found an issue we cannot resolve and any suggestions would be helpful. We have noticed that after a while the RS232 stops working. We have tracked this down to the HANDLE hCom keeps increasing and when this reaches 1023 the COM returns an unknown error "5003". Is there a way to reset this hCom reference? Thanks Richard

Post by timvh on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
You should only open de COM port once and then leave it open. This hCom should not keep on incrementing. (off course when you are done communicating, you need to close the COM port)

Post by phoward131 on Text List Fallback Value ^{CODESYS Forge talk (Post)}
I am relatively new to Codesys and I'm trying to develop an HMI that displays what mode a particular device is in based on an integer value. I am currently using dynamic texts with a text list which works fine but I am looking for a way to display a particular string (ie 'Unknown') when the index doesn't match any of of the indices in the text list. I can enter 'Unknown' in the text property of the text field element which works as expected but it displays the single quotes on the visualization. How can I escape these quotes to simply display the word Unknown? Thanks!

Post by struccc on Release SP20 - Changes in behaviour? ^{CODESYS Forge talk (Post)}
Dear all, I've just started to migrate some of my ancient projects to SP20. There is one strange error (?) I have noticed so far. In a method call, depending on the circumstances I would like to return reference to an object, or an invalid reference: METHOD Add_EVT_OUT : REFERENCE TO FB_MSG VAR END_VAR IF __ISVALIDREF(refMSG_Entry) THEN Add_EVT_OUT REF= MANAGER.AddMsg_EVT_OUT( refMSG_Entry, _Get_EVT_Message(MSG_EVENT.OUT), _Get_EVT_AddCode(MSG_EVENT.OUT) )^; ELSE Add_EVT_OUT := 0; END_IF So far setting a reference variable to 0, did this. But now, the expression Add_EVT_OUT := 0; gives an error: [ERROR] DB_WTP_370: Add_EVT_ACK MSG_TRIGGER_EXT: C0032: Cannot convert type 'BIT' to type 'REFERENCE TO FB_MSG' Naturally... I can write: Add_EVT_OUT := DWORD#0; But is this the correct way? Is there any constant I could use instead, like "NULL"? Or this is totally wrong and to be avoided?

You should use this method: VAR NULL:REFERENCE TO FB_MSG END_VAR Add_EVT_OUT REF= NULL;
