Hi thanks once again, Yes it supports because using python scripting I'm able to send data from the rasberry raspberry and receive it on my pc and vice versa (Image attached). But when using the CoDeSyS I just got red flags. Any light on this problem?

Seems like you use SIZEOF as size, but you need to use LEN as size of data which you want to write.

Despite working on it for days, I haven't achieved any results. I followed the necessary steps one by one as mentioned in the file you sent, but there hasn't been the slightest change. I couldn't find the step you mentioned "Set the 'Can Board Type' to PCAN USB" in the Word document. There is no such setting anywhere I looked. Is there a more detailed explanation available, or can you explain it in more detail? What am I missing?

Post by youness on No source code available (cip object) ^{CODESYS Forge talk (Post)}
Hi yotaro, hope your problem was resolved. I had the same, but with an other library title. This exception is not detected during compilation, but rather at a given position in the program (when switching to a given visualization). Although the exception is generated at this point, it does not involve the visualization in question. This error is due to one of 3 reasons: 1) A division by zero somewhere: The program is able to detect divisions by zero at compile time. But in the case of a variable, which takes a valid value at init and changes to 0 at a later stage. 2) An invalid pointer: (either because it has a value of 0, or because it points outside the memory reserved for the program) is being dereferenced. Locate any pointers or interfaces you have in the code and check them - you should also be wary of mixing inline modifications and pointers. 3) Array overflow: Generally when a processing operation is executed outside the array's definition range. Example: a write loop with n iterations is executed on an array of dimmension n-1. On the other hand, the error message may not appear. In the latter case, the error may have fatal consequences, as the overflow has induced writing to potentially forbidden memory areas. This problem can be explained by the fact that it's not always the adjacent memory areas of PLC_PRG that are overwritten, but the memory areas that are randomly allocated to the array during compilation. In this case, however, there is no entry in the log, so you need to integrate the "Implicit Check function", which checks the line of code generating the error. To integrate this functions, click on Application --> POU for implicit controls Regards,

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
It's good that you've found a workaround. But it's bad that you need one. The array length auf my struct is 16. My struct also contains other arrays of structs. It contains a total of 1716 variables. I have tested saving and loading extensively under version 4.3.0.0. It looks good. I couldn’t find any problems. Maybe it helps to reinstall the update (see previous post). Otherwise you could try my test project (first post). This should work with version 4.3.0.0.

Post by fless on FB having single input but initialized with Array ^{CODESYS Forge talk (Post)}
Why will it retain the sum value from the last call? This is how PLC work. Usually variables only get initialized after a download or a reset (i.e. power loss). RETAIN variables are saved in a special kind of RAM and keep their value after a power loss. To initialize variables on every call of your FB use the VAR TEMP block. VAR_TEMP sum : INT; END_VAR

Post by corriibme on Setting array values with JSON Utilities SL ^{CODESYS Forge talk (Post)}
It turns out that you can build JSON structures without ever calling the JSONBuilder function block directly. Instead, create a pointer to JSON.JSONData and invoke the necessary methods on its dereference. The parent object has a parent index of -1 (and an index of 0). EVERY other item (including keys, values, empty arrays and sub-objects) created by the setX methods needs the index to increase by 1. Then use the JSONByteArrayWriter FB to generate your JSON string

Post by toffeebonbon on EL7041-0052 - does it run with EL7041 SoftMotion? ^{CODESYS Forge talk (Post)}
Good morning everyone. In my setup I am trying to use a couple of EL7041-0052 (the EL7041 variant without terminals for an encoder) to run stepper motors without feedback. When using the softmotion drivers for the EL7041 (Rev22 and Rev24, even selecting external feedback type doesn't work) the device log shows warnings for the corresponding hardware: "SDO write error 0x1 -> 0x8012:0x08 eError 0x1 AbortCode 0x6090011". 0x8012:0x08 is the register for the Feedback Type. My best guess was setting the the register value in the start parameters to zero, but the result is the same. What else can I try to get the hardware to work? I have screenshots attatched showing the running fieldbus and the log messages. EDIT: One clarification: the "device log" that shows the error is the PLC, not the ethercat terminal. The log of the terminal itself shows neither errors nor warnings. BR Robert

Post by manuknecht on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge talk (Post)}
Hello all I am using an AxisGroup with the Gantry2 Kinematics to move a 2D-Gantry system. When creating the AxisGroup, the SoftMotion_PlanningTask is created automatically with a cycle time of 2 ms in my case. I realized that the maximum cycle time of this task can spike to very high values (up to 60 ms) at lower speeds of the motion, leading to synchronization issues and errors on the axes. The same behaviour - though not as drastic - can be observed with virtual axes too. Is this behaviour intended or to be expected? Can the cycle time or type of the SoftMotion_PlanningTask be changed to prevent these errors? Or is there another fix for this issue? I tried changing the cycle type to Freewheeling, which solved the synchronization issues, but caused an error on the AxisGroup after a while, reading SMC_CP_QUEUE_UNDERRUN. Thanks in advance and best regards Manuel

Hi, I'm trying to monitor a specific PGN which I have it sending a pulse every 500mS Problem: Using the Watchdog for the ECU does not really help me as I have multiple instances with separate PGNs, if a PGN goes ghost, the ECU watchdog won't be flagged as the others will be running. I found the J1939.ReceiveWatchdog & J1939.ReceiveParameterGroup function blocks and they seem like a good solution for my problem, I just can't get them to work from my understanding you just build the J1939.ReceiveParameterGroup once and then connect it's output to the J1939.ReceiveWatchdog, here's my CODE for the setup HEARTBEAT_TIMER(IN:= TRUE, PT:= T#1000MS); //turn-on delay because of initialization race IF HEARTBEAT_TIMER.Q= TRUE THEN Glob_Var.DisplayReceive.xExecute:= TRUE; Glob_Var.DisplayReceive.itfECU:= Valve_X; Glob_Var.DisplayReceive.dwPGN:= 65511; Glob_Var.DisplayWatchdog.xEnable:= TRUE; Glob_Var.DisplayWatchdog.itfParameterGroup:= Glob_Var.DisplayReceive.itfParameterGroup; Glob_Var.DisplayWatchdog.tTimeout:= T#1500MS; END_IF Notes: Glob_Var.DisplayReceive is of type J1939.ReceiveParameterGroup Glob_Var.DisplayWatchdog is of type J1939.ReceiveWatchdog The above code is done once and not cyclically I'm monitoring Glob_Var.DisplayWatchdog.xError cyclically

Post by mubeta on parker servo and position ^{CODESYS Forge talk (Post)}
In general, drives have parameter sets to adjust behaviour in such cases: position recovery, adaptation with resistant torque, out-of-position window failure, etc. (Much depends on the type of configuration set for the axis: positioner, speed controller, torque controller, etc.). I have used that type of drive very little, in only two cases and a long time ago. To tell you what is normal is impossible. I know by reputation they are very simple objects, without too many pretensions and adjustments possible. Try running traces by monitoring actual position, motor current, torque and following error. These are the most sensible curves to understand what is going on. Maybe by fine tuning the motor tuning, the current controller or the speed controller you will get something closer to what you want. For example, from DS, the motor has a standstill torque of 3 Nm. Observe with traces whether this is effective: motor current trend. And afterwards, when you have your own accurate picture of the situation, you can also hear from the product's local support to see if you can steal a few more things from it performance-wise.
