Post by mascara on JOG continues in WCS ( SMC_GroupJog2 ) ^{CODESYS Forge talk (Post)}
I'm using the SMC_GroupJog2 block from the SM3_Robotics library for manual movement of an AxisGroup in WCS coordinates. The observed behavior is: When pressing X+, the X-axis starts moving correctly. If I press Y+ during the movement, the block interrupts the current movement and starts a new movement in X and Y. If I release any button, all axes stop, even if another button is still pressed. Example: Pressing X+ → X moves Pressing X+ and Y+ → X stops momentarily and starts XY movement Releasing X+ while holding Y+ → all axes stop The expected behavior would be: to allow simultaneous continuous movement on multiple axes to not interrupt movement when another axis is added or removed. Is there a correct configuration of SMC_GroupJog2 to achieve this behavior, or is there another block more suitable for continuous manual jog in AxisGroup (WCS)?

Two issues. Ive been struggling to get the user management the way I want it. I want to protect the device from unauthorized upload/download, but I do not want login requirement on webvisu. The combination that seems to work is to use "runtime device user management" while keeping the visu user management in "legacy mode"? Initially this seemed to work, but now images are not loaded when using direct access, while they are still shown if I access the webpage via Automation server. Im guessing its connected to the authorization changes? Anyone able to help out? Thanks Also, I read that legacy mode should be avoided, is it possible to use "runtime based visu user management" while keeping direct access to the webpage without login.

However when using static IP I have not managed to reach functioning state. Trying to replicate the situation on my desk. Having a static IP on the "debian host" and a connection to my computer which then routes traffic on to internet. I have entered settings for gateway and netmask. I can ping from my "debian plc host" to internet and also do "curl google.com" so traffic seems to find its way through and back, still "Automation server" will not find the gateway. Any hints how a manual configuration should be done? Is it possibly a "firewall" issue of my "normal router"? Thanks for any help! Per

Post by timvh on CPU + EtherCAT redundancy ^{CODESYS Forge talk (Post)}
It works well with two Wago 750-8210's. I helped a few customers setting this up. But it should work with any device which can control EtherCAT I/O, is real-time and has sufficient network interfaces. Two network adapters can be used to create a redundant EtherCAT network (you need 2 additional switches for this). The other network adapters can be used to interconnect the 2 PLC's (synchronization). We noticed that if you exchange variable lists that there could be some issues if you have long lists. So what we did is use a SoftPLC on a server that contains all the settings which continuously sends network packages (GVL sender) and which is received by both PLC's (network receiver). Switching over is done in milliseconds. The bus doesn't notice the change-over. EtherCAT communication works flawlessly.

Post by timvh on EXCEPTION [watchdog] how to find position cause ^{CODESYS Forge talk (Post)}
Monitor what your current cycle time is (in the Task Configuration when you are online). If this is sometimes close to 200ms, then change your code (e.g. limit the loops, or prevent copying a lot of data between objects). Or just set the Watchdog time (or sensitivity) higher if you don't care that it sometimes takes longer than 200ms. If you want to find out which objects in your application consume the most time, then buy a PDE (Professional Developer Edition) license. With this you get a license for the Profiler. This can help you a lot to find the root cause, because it will create a nice overview of all objects, their calls and the time (percentage) it takes to execute it.

Post by konstantin on CAM Motion Recover after STO ^{CODESYS Forge talk (Post)}
Hello, one of the projects I work on is about a racetrack collator with two independent belts on it - two different servo motors. Both motors share the same mechanical frame and there is a train on a belt that collects items from the input conveyor. The way the motion is performed is the following - there is a virutal master axis and both real axis are synchronised with different cam motion profiles. The problem is when an STO is triggered on any of the slave axis, the synchronization process starts from position 0 of the slaves. How can I force the slaves to retain their current position until the master passes their position? Then the slaves should catch up with the master according to the profile, the slaves should not start synchronization from 0 position. Best Regards Konstantin Kolev

It seems the homing mode is in CiA402 Advanced mode but how can you not have the homing mode in both modes? It is a vital part of any servo system. If I use the SoftMotion standard demo mode, I can move the servo absolute and relative but cannot home it. But in SoftMotion Light mode, I cannot execute any motion function. Here is the official manual for i950 servo drive - i950 Documentation Best Regards Konstantin Kolev

Post by gseidel on CAM Motion Recover after STO ^{CODESYS Forge talk (Post)}
Dear Mr. Kolev, I'm not sure I understood correctly. But this is my take on your question: When the STO of the slave is triggered, store the current master position (e.g. 225 units) After the reset of the slave error, call MC_SetPosition on the virtual master and reset it to the stored position (225 units) Optionally, before MC_CamIn is restartet, move the slave back to the slave position corresponding to the stored master position. (If you do this, no ramping in will be necessary) Restart MC_CamIn, with absolute master position and absolute slave position. Choose the StartMode that is appropriate for your machine.

Post by poliautomacao on Absolute movement controlled by an external encoder. ^{CODESYS Forge talk (Post)}
Hello, I made this configuration, I'm moving the encoder value to SM_Driver_PosControl.in.wActPosition. When I make the absolute movement of my PosControl axis, my physical drive axis rotates perfectly, but I noticed that the movement is not followed by the encoder. That is, if I hold the encoder and keep it in position 0, the PosControl axis makes the absolute movement of 314 mm and stops, which is strange because the encoder is at 0. Theoretically, the PosControl axis should accelerate to try to compensate for the movement error. I haven't yet achieved perfect functionality.

When I compile my library on its own, no errors occur. However, when I use this library in a project and compile the project, I get an error indicating that the SysTime data type is not recognized. This happens even though the SysTime library is visible as a dependency under my library. Does anyone know how to correctly include a library within another library so that the project recognizes the sub‑library without causing compilation errors?

Post by thommy54 on CODESYSControl_User cfg richtig konfigurieren ^{CODESYS Forge talk (Post)}
Hallo, nach Erwerb eines neueren Raspberry pi 4 (V1.5) musste ich zwangsläufig von Codesys 3.5.16 hochwechseln - ich habe auf 3.5.20.1 geupdated. Da schlugen mir plötzlich ne Menge Einschränkungen entgegen, deren Behebung einige Zeit dauerte. Eine davon ist, das ein SysFile.SysFileOpen nicht mehr funktioniert. Ich habe das Problem mit Einträgen in der /etc/CODESYSControl.cfg behoben: [SysFile] FilePath.1=/etc/, 3S.dat IecFilePath.1=/proc/, cpuinfo IecFilePath.2=/proc/, iomem PlaceholderFilePath.1=/sys/devices/w1_bus_master1, $OneWire$ PlcLogicPrefix=1 ; ; ---------------------- ; selbst eingefügt PlaceholderFilePath.2=/home/root, $my_home_root$ PlaceholderFilePath.3=/etc/init.d, $my_conf$ PlaceholderFilePath.4=/var/lib/mpd, $my_music$ PlaceholderFilePath.5=/root/Rasp_SPS_Filesystem, $my_Rasp$ Ob die Einträge sich etwas überlappen, kann mir gern jemand sagen, das ist aber nicht das Problem. Ich habe bei den vielen Versuchen, das Teil zum Laufen zu bringen, bemerkt, daß die Einträge auch ganz schnell mal verschwinden. Das ist ja auch so beschrieben, wenn die nächste Version kommt, sind meine Einträge weg. Da ich ähnliche Probleme mit dem Funktionieren von "SysProcessExecuteCommand2()" hatte, die ich ebenfalls mit Einträgen in die /etc/CODESYSControl.cfg hätte beheben können, habe ich gelesen, das man "private" Einträge lieber in die Datei /etc/CODESYSControl_User.cfg machen soll. Gesagt getan und "SysProcessExecuteCommand2()" lief: [SysProcess] Command=AllowAll Command.0=shutdown Aber auch irgendwo stand, das so ein Beteichner wie [SysFile] oder [SysProcess] nur einmal in den beiden Files /etc/CODESYSControl.cfg oder(!) /etc/CODESYSControl_User.cfg vorkommen darf. Das ist nun die eigentliche Frage! Ist das so ? Bei [SysProcess] ist das kein Problem, das gibt es in /etc/CODESYSControl.cfg nicht. Aber bei [SysFile] sieht das anders aus. Da sind 5 Zeilen schon in /etc/CODESYSControl.cfg drin. Würde ich diese in die User-Datei rüberschieben, könnte beim nächsten Update was fehlen oder, oder... Lasse ich es so wie es ist, sind meine Einträge beim Update weg - das sollte ja verhindert werden. Kann da jemand genaue Auskunft geben ?? Vielen Dank Thomas

Die Url-Streams habe ich gelassen wie sie vorgegeben waren: urlStream := CONCAT('http://', CONCAT(sIPAddress, '/video.htm')); urlPicture := CONCAT('http://', CONCAT(sIPAddress, '/cam_pic.php')); In der Webvisu im Browser komme ich maximal dahin wie im Screeshot Video_Visu_1 zu sehen. Also scheint der Link zu video.htm zu klappen. Das der zu cam_pic.php nicht klappt, wundert mich nicht, denn es existiert nicht und wird auch nicht evtl. am rechten Ort angelegt. Ich bin mir vollkommen im Unklaren: muss da was auf dem Raspberry Pi im Hintergrund laufen , z.B. raspivid . Welcher Programmteil bedient die Cam ?

Post by otbeka on CAA File Handling: "Read only" error ^{CODESYS Forge talk (Post)}
Hi, On CODESYS V3.5.19.50 I am using the latest 3S File Access library (CAA File & CAA Types) to save and retrieve configuration data from the User Data section of an SD card, via file called config.txt. The application reads the file to memory once upon initialisation, and then the only other operation is overwriting the file with the updated configuration whenever the user changes the settings. An issue is ocurring, seemingly randomly, where the config.txt file, and all surrounding directories, cannot be written to by the unit, returning a READ_ONLY_CAA error upon file open. This sometimes does not clear even after power-cycling the PLC several times, yet checking the file permissions with ls -l shows normal read, write, and execute access. I am wondering if this is caused by the PLC itself or by an issue in my application. I have included my CAA File handler function block (SD_Card_Bin(FB).txt) and any associated types/calls below: TYPE ConfigData : STRUCT Config : ARRAY[0..256] OF STRING(64); NumberOfStrings : UDINT; END_STRUCT END_TYPE TYPE Buffer : STRUCT Data : ARRAY[0..SIZEOF(ConfigData)] OF BYTE; DataLength : UDINT; END_STRUCT END_TYPE A case within my MAIN PRG: mode.WriteConfigDataToFile: VisuElems.CURRENTVISU := 'Screen_Write'; IF xModeHasChanged THEN iErrorCount := 0; iRoute := 0; END_IF CASE iRoute OF 0: inBuffer := ConfigData_To_Buffer(GVL.UnitData); xConfigError := FALSE; xDataConfigured := FALSE; iRoute := 1; 1 : //Read Data from Card SD_Card_Bin.strFileName :=FileName; SD_Card_Bin.iFileOperation := 2; SD_Card_Bin(xExecute :=TRUE, WriteBuffer := inBuffer, xDone =>xDataConfigured, xError=>xConfigError, strErrorCodes=>strError); IF xDataConfigured THEN SD_Card_Bin(xExecute :=FALSE); IF xConfigError THEN iRoute := 32767; ELSE iRoute :=100; END_IF END_IF 100: // The end bCurMode := mode.DisplayProcessVariables; 32767: // Config error iErrorCount := iErrorCount + 1; IF iErrorCount > 2 THEN // Repeats 3 times, if no progress abandons and returns error bCurMode := mode.WriteError; ELSE iRoute := 0; // Try again END_IF END_CASE I'd like to rule out my application as the cause of this bug - help via comments or criticism would be greatly appreciated.

Post by dnordenberg on BOOL variable in OPC UA and modbus simultaneously ^{CODESYS Forge talk (Post)}
How can I have an BOOL variable that is read/write in both modbus TCP server and from OPC UA at the same time? Variables with %MX.n %QX.n addressing which is used for BOOL/coils in modbus server is not allowed in OPC UA symbol list on Schneider M251 controllers. I have already asked on Schneiders forum but there are not a lot of codesys experts over there :( So OPC symbols can't have a address and the modbus TCP server needs a address. So how should I do it then? It seems like an impossible combination. Since I want read/write access from both ways I can't just simply make a second variable and assign it the value of another since it would be a one way assignment. I also tried using VAR_CONFIG which then makes the address syntax %Q or %M in my main variable list and that fools OPC UA Symbol Configuration to allow it and then I add the complete %MX.n address of it in the VAR_CONFIG list. This semi works, I can toggle the BOOL from modbus but the OPC UA symbol seems to be read only. It displays symbol status but nothing happens when I toogle it. I think I need another way to have the variables and symbols pointing to the same bits in memory... My plan B is to write a BOOL array compare FB that saves a history bit from previous cycle and if that does not match current status at next cycle for either the OPC symbol or the modbus variable then it copies the new status over to the other. Maybe ugly but it's like my last alternative. Kind regards David
