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 martinlithlith on Device User Logon and No device is responding.. Pi4b codesys 3.5 SP19 2 + (64-bit) ^{CODESYS Forge talk (Post)}
Hi! Im slowly starting to loose it and i need som help! After a few night of reading up and testing i´m still stuck as a rock and you guys and girls are my last resort for this project. Basic facts; Win 11 Codesys 3.5 SP19 2 + (64-bit) Raspberry pi 4 model b 2 gb Raspian release 11 aarch64 What keeps me up late at night; Username and Password when trying to connect to device and device only beeing connectable for a few seconds. Some of the things I have tried; Username and passord; Credientials from the raspberry Administrator Administrator admin admin Admin Admin administrator administrator Usernames and passwords that I sometimes use (this was a longshot i know, but i was running out of ideas and energy). :) Epand filesystem, activating i2c, spi, 1-wire I can start the gateway and start the runtime. I cant install the edgearm64, arm64 runtime package eventhough I guess i should, i get code [ERROR] Error output: dpkg: error processing archive /tmp/codesysedge_edgearm64_4.8.0.0_arm64.deb (--install): [ERROR] Error output: package architecture (arm64) does not match system (armhf) [ERROR] Error output: Errors were encountered while processing: [ERROR] Error output: /tmp/codesysedge_edgearm64_4.8.0.0_arm64.deb code as a respons. I have tried to Reset Origin Device - no change. I have tried to remove the /etc/CODESYSControl_User.cfg [CmpUserMgr] but i could not find it and i was not sure if i should add it instead but i did not want to mess somthing up. I have tried to create a second gateway with the specific ip if the pi, that did not help. Could it be that i´m currently connected to the pi through WIFI? I can ping the pi and I can connect and control it through VNC. When i scan to select gateway target (scan edge gateway) i find 17-21 devices but can find the pi throug the mac adress. I started of trying to use the "CODESYS Control for Raspberry Pi SL" (I have a license sience earlier) as i read somewhere that this could be used on a Pi4 as well but now i´m trying with the MC SL, no changes, same problem. Right now - gateway version 4.8.0.0 (edgearmHF, armhf), Runtime Package 4.5.0.0 (raspberry, armhf). Any sugestions are very welcome! As mentioned above, theese are some of the things that i have tried/done - but i have been going at this for a while. Best, Martin

Post by dantheman on Connecting to SoftPLC Only Works By Turning Off Modbus Ethernet Port ^{CODESYS Forge talk (Post)}
I have an IPC with 2 ethernet ports and 1 Wi-Fi. I'm using ModbusTCP with the ethernet port named "enp2s0" connected to my remote I/O. This works fine when testing with Python and also works with CODESYS, but CODESYS is only able to scan for the Linux SoftPLC when I turn off the "enp2s0" interface. In other words, I can't get online with the IDE if I want my ModbusTCP comms to run with CODESYS. I'm using a Linux SoftPLC that has the following entry in CODESYSControl.cfg, hoping that this will allow me to connect with "enp1s0" or "wlp3s0", and leave "enp2s0" for field comms, but this seems to only make the source IP of the ModbusTCP comms to be bound to "enp2s0". That last point is the case only if I don't restart the service, but if I do restart the service after changing the config file, the source IP for the ModbusTCP comms then becomes the one for "enp1s0", which is very confusing to me: [SysSocket] Adapter.0.Name="enp2s0" Adapter.0.EnableSetIpAndMask=1 On the device list, I only have "enp2s0" given as the ethernet device that has the ModbusTCP master & slave beneath it, shown in Screenshot 1. On the IPC, I can ping the ModbusTCP client (remote I/O) from "enp2s0", and I've attached a Wireshark capture of running ModbusTCP from the CODESYS runtime as Screenshot 2, 3 & 4 (again, I can't get online when this is running, I have to turn off "enp2s0" to connect even when it's idle and I don't have an active TCP session with my Python tests). Like I explained above, the source IP is "enp1s0", even though the ethernet device on the project is "enp2s0". I was lucky to catch the red message that showed the source IP that makes sense to me (the one for "enp2s0"), but for some reason that connection was reset and I never saw that packet again. I've also tried this with Auto-reconnect both enabled & disabled, for the ModbusTCP Master device. I also have to turn off "enp1s0" and then turn it on, just so that I can have the ModbusTCP comms running from "enp2s0" (which is not intuitive in any way to me, I'd love some help understanding that phenomenon as well) in the weird manner that I've described above. I would be very appreciative if someone can help me figure out this pickle. I'd love to just connect to CODESYS through my Wi-Fi interface and leave my ethernet ports for field comms.

Post by mubeta on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Hello everyone, I have a very simple program for the process, but it's driving me crazy and I can't see the problems I'm left with: Short topological description: Dual Core Berghof controller with softmotion runtime version 3.5.19.30; Two axes with servodrive on canopen bus, clocked distributed from master; Ethercat I/O node; 2 ms ethercat task, 2 ms canopen bus cycle time; I/O objects of the canopen master and canopen drives connected to the ethercat task cycle; Problem 1: Two separate programs each manage their own axis and drive, with separate state machines. A first axis moves primarily in velocity, except having to position itself absolutely at a predetermined point at the end of the job; the second axis, on the other hand, is a paper unwinder that changes, for each job cycle, from actions in absolute, relative, and cam displacement with the master axis. Well, the state machine of both axes was written in such a way as to call running the useful FB and change it on state change in this way: CASE i_stateMachine OF 0: o_Power(Enable := TRUE, bRegulatorOn := FALSE, bDriveStart := FALSE, Axis := o_PaperUnwinderAxis); o_MoveAbs(Execute := FALSE, Axis := o_PaperUnwinderAxis); o_MoveRel(Execute := FALSE, Axis := o_PaperUnwinderAxis); o_CamSelect(Execute := FALSE, Master := o_MachineAxis, Slave := o_PaperUnwinderAxis, CamTable := cam_PaperUnwinder); o_CamIn(Execute := FALSE, Master := MachineEncoder, Slave := o_PaperUnwinderAxis); o_CamOut(Execute := FALSE, Slave := o_PaperUnwinderAxis); o_SetPosition(Execute := FALSE, Axis := o_PaperUnwinderAxis); IF ... THEN i_StateMachine := 10; END_IF; 10: o_Power( Enable := TRUE, bRegulatorOn := TRUE, bDriveStart := TRUE, Axis := o_PaperUnwinderAxis ); IF o_Power.Status THEN i_StateMachine := 20; END_IF; 20: (* Avanzamento carta *) o_MoveAbs( Execute := TRUE, Position := o_Somewhere, Velocity := 25.0, Acceleration := 3666.7, Deceleration := 3666.7, Jerk := 48000.0, Direction := MC_DIRECTION.positive, Axis := o_PaperUnwinderAxis ); IF o_MoveAbs.Done THEN o_MoveAbs(Execute := FALSE, Axis := o_PaperUnwinderAxis); i_StateMachine := 30; END_IF 30: d_HomingPosition := ...; o_SetPosition( Execute := TRUE, Position := d_HomingPosition, Mode := FALSE, Axis := o_PaperUnwinderAxis ); (* ... *) IF o_SetPosition.Done = TRUE THEN o_SetPosition(Execute := FALSE, Axis := o_PaperUnwinderAxis ); o_LogServer.Append(sMessage := '...', lscClass := LOGSERVER_CLASS.ALWAYS, sdt := o_CommonsMgrData.systime.sdtLocal); i_StateMachine := 40; END_IF; 50: ... The code above is a sketchy example of what I wanted to write. But it gives me a spot problem: in some, the state change results in a drive error, which is unrecoverable except with a reinitialization via SM3_ReinitDrive(). Things are improved a little if in the program I always run the call of all softmotion blocks in this way: o_Power(Axis := o_PaperUnwinderAxis); o_Jog(Axis := o_PaperUnwinderAxis); o_Halt(Axis := o_PaperUnwinderAxis); o_MoveAbs(Axis := o_PaperUnwinderAxis); o_MoveRel(Axis := o_PaperUnwinderAxis); o_CamIn(Master := MachineEncoder, Slave := o_PaperUnwinderAxis); o_CamOut(Slave := o_PaperUnwinderAxis); If I don't execute all the calls of all the motion FBs used, when exchanging machine state often (but not always), the axis goes into error with event id THE_FB_WASNT_CALL... Done a little diagnostics it seems that the FBs return the bDone, before they are completely terminated. I tried doing the machine state exchange not with the bDone bit of the FBs, but with the 'standstill' state of the axis. It didn't seem to change anything. Problem 2: During the use SM3_ReinitDrive() I get the erro in the log: "NetID 0: SDO read error for object 16#607C..." Assuming that the device involved it's one of the two servodrive, (no others device are present in the network), I don't found any object 0x607C in the 'possible object list in/out' of the two drive, and I don't understand where this object can be listed. So any ideas and suggestions regarding these two issues will be very, very welcome. If you need the source project, I am willing to send it.

Post by ihatemaryfisher on Sorting array of any-sized structure ^{CODESYS Forge talk (Post)}
In my machine's operation, I need to display multiples tables containing arrays of structured variables. The arrays change during operation, and my supervisor has advised me to write a new bubble-sort for each array. I think I can make a function to sort an array of any data type. This was my own project, and I'm a relatively new coder. I want to know the weaknesses in my approach, and a better method, if one exists. As far as I can test, the function accepts an array of a structured variable of any size, and sort it by any VAR in that structure. But it relies heavily on pointers, which I've heard are bad practice? Function call: // SORT BY BYTE-SIZED VAR IF xDoIt[6] THEN FUNBubbleSortSansBuffer( IN_pbySourcePointer := ADR(astArray[1]), // address of first byte in first element of array IN_pbyComparePointer:= ADR(astArray[1].byCompByte), // points to first byte of the comparing variable (variable you sort by) IN_uiStructureSize := SIZEOF(TYPE_STRUCTURE), // size, in bytes, of the structured variable IN_uiCompareSize := SIZEOF(astArray[1].byCompByte), // size, in bytes, of the comparing variable (variable you sort by) diArrayElements := UPPER_BOUND(astArray,1), // number of elements in array IN_xSmallToLarge := xSortOrder // whether to sort by small2large or large2small ); END_IF Function: FUNCTION FUNBubbleSortSansBuffer : BOOL VAR_INPUT IN_pbySourcePointer : POINTER TO BYTE; // points to beginning of array (first byte of first element) IN_pbyComparePointer: POINTER TO BYTE; // points to first byte of the comparing variable (variable you sort by) IN_uiStructureSize : UINT; // size, in bytes, of the structured variable IN_uiCompareSize : UINT; // size, in bytes, of the comparing variable (variable you sort by) diArrayElements : DINT; // number of elements in array IN_xSmallToLarge : BOOL; // whether to sort by small2large or large2small END_VAR VAR j : DINT; // repeat iteration over array until array ends i : DINT; // iterarte over array, swapping when necesary k : DINT; // iterator from 1 to size of structure (stepping 'through' a single element in array) dwSize : DWORD; // internal var for use in MEMUtils.MemCpy(<size>) // FOR SORTING BY BYTE VAR pbySourcePointer : POINTER TO BYTE; pbySourcePointer2 : POINTER TO BYTE; pbyComparePointer : POINTER TO BYTE; pbyComparePointer2 : POINTER TO BYTE; pbyPointerToBuffer : POINTER TO BYTE; // pointer to single byte buffer byBufferByte : BYTE; // single byte buffer END_VAR dwSize := UINT_TO_DWORD(IN_uiStructureSize); // get structure size (number of bytes) pbyPointerToBuffer := ADR(byBufferByte); // assign pointer to address of buffer byte (because MEMUtils.MemCpy requires a pointer input) CASE IN_uiCompareSize OF // depending on the size of the VAR to sort by (current functionality for BYTE and WORD/INT 1: // BYTE (8 BIT) FOR j := 1 TO diArrayElements DO // for number of elements in array FOR i := 1 TO (diArrayElements-1) DO // same thing, but row[i+1] row is included in swap logic pbySourcePointer := IN_pbySourcePointer + dwSize*(i-1); // point at #1 byte in array element[i] pbySourcePointer2 := pbySourcePointer + dwSize; // point at #1 byte in array element[i+1] // NOTE: because of memory locations, each array element is offset from one another by a number of bytes equal to the size of the structure // We can "walk" from array[i] to array[i+1] via steps equal to the size of the structure // e.g., ADR(array[i+1]) == ADR(array[i]) + SIZEOF([array datatype]) pbyComparePointer := IN_pbyComparePointer + dwSize*(i-1); // point to sorting variable in array element[i] pbyComparePointer2 := pbyComparePointer + dwSize; // point to sorting variable in array element[i+1] // using sort order (small -> large/large -> small) IF SEL(IN_xSmallToLarge, (pbyComparePointer2^ > pbyComparePointer^),(pbyComparePointer2^ < pbyComparePointer^)) THEN // This is where it gets tricky. We've identified pointers for the starting bytes of aArray[i] and aArray[i+1] // and we know the size of aArray[i]. We are going to swap individual bytes, one at a time, from aArray[i] and aArray[i+1] // this allows us to use only a single byte var as a buffer or temporary data storage // e.g., consider a structure consisting of a word, a byte, and a string. it is stored like this // |------WORD-------| |--BYTE-| |STRING------...| // astArray[1] == 1000 0100 0010 0001 1100 0011 1010 1010.... etc // astArray[2] == 0001 0010 0100 1000 0011 1100 0101 0101.... etc // performing a single swap (copy into a buffer, etc.) of the first byte of each array element creates this // astArray[1] == 0001 0100 0010 0001 1100 0011 1010 1010.... etc // astArray[2] == 1000 0010 0100 1000 0011 1100 0101 0101.... etc // incrementing the pointer adresses for the swap by 1 and swapping again swaps the next byte in each array element // astArray[1] == 0001 0010 0010 0001 1100 0011 1010 1010.... etc // astArray[2] == 1000 0100 0100 1000 0011 1100 0101 0101.... etc // continuing this from k to SIZEOF(TYPE_STRUCTURE) results in a toally swapped row FOR k := 1 TO IN_uiStructureSize DO // copy single byte[k] of array element 1 to buffer MEMUtils.MemCpy(pbyDest := (pbyPointerToBuffer), pbySrc := (pbySourcePointer+k-1), dwSize := 1); // copy single byte[k] of array element 2 to 1 MEMUtils.MemCpy(pbyDest := pbySourcePointer+k-1, pbySrc := (pbySourcePointer2+k-1), dwSize := 1); // copy buffer to byte[k] array element 2 MEMUtils.MemCpy(pbyDest := (pbySourcePointer2+k-1), pbySrc := pbyPointerToBuffer, dwSize := 1); END_FOR END_IF END_FOR END_FOR
