Post by mubeta on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
How are the servo drives controlled? EtherCAT, step/dir pulses, other? CANOpen, 1 Mb/s, bus load 35%, cycle time 2ms. Another thought is that - if it's step/dir pulse based control - the pulses from the PLC to the drive are getting missed/lost at high frequencies? If that's the case then there would be multiple troubleshooting steps/corrections that could be investigated. Here, it seems to me that we are getting completely off track with the observed problem. You could try to create a simplified program I had already written this elsewhere. The program before being brought into machines was exhaustively tested in SW emulation and the problem did not occur. However, in emulation I was interested in checking other aspects of the process, not this specific one which is for real a correction made necessary after the fact. The part of the program that does this correction with the function mentioned in the topic, came up from its origins, but I didn't know or didn't think it was really useful. A scruple that later turned out to be necessary. However, for now I do not think I will spend any more time on this verification, already lacking any to do my normal. I remain amazed, however, that a function intended to correct the axis position with the motor in motion and that it should not interfere with this, in fact instead changes behavior as the motor speed changes. Mah! When you manually control the motor directly from the servo drive software at the speeds you are calling for, does it move precisely to the target position? The drive and motor have been working fine for about 10 years. In replacing the machine control system, I opted for CoDeSys where before there was something else. But this is not the subject of the problem. What I need to resolve is the fact that a clutch specially placed at a certain point can slip and, therefore, I have the undeniable need to phase the 'prime mover' to the mechanical position of the machine, detected by a cam for each turn, in order to properly stop at its optimum point. Which for now I have ruled out doing. In fact, if I really have to say, since we have now gone brutally OT, I originally thought that this clutch should only come into action in cases of extreme necessity, as happens in most trials. But this one, the way it is made, slips more easily than I could estimate and the servo-controlled 'prime mover,' and the machine, get out of phase, maybe by a little, but frequently, and when the machine work at it's high speed, (in fact all of the time), I can't adjust properly the 'prime mover' position at fly.

Post by ucconversions on displaying all incoming CAN bus messages ^{CODESYS Forge talk (Post)}
Hello Im using CAN API Im receiving CAN messages with no problem. below is my code. METHOD ProcessMessage VAR_IN_OUT ( Incoming message ) Message : CAN.RxMESSAGE; END_VAR VAR i: USINT; END_VAR recvCANid := Message.udiCanID; IF recvCANid = 16#18FF8247 THEN UserVarGlobal.g_countMsg_RPMset := UserVarGlobal.g_countMsg_RPMset + 1; FOR i := 0 TO 7 DO myDataFF82[i] := Message.abyData[i]; END_FOR END_IF but in this way I can only display CAN messages which I know its ID. I want to display all incoming CAN messages for example first incoming CAN message - I assign it into a variable Message1. second incoming CAN message - I assign it into a variable Message2. third incoming CAN message - I assign it into a variable Message3. Can you give me guidance? Thank you BR

Post by mubeta on Reset problem with CMZ SD/SVM drive ^{CODESYS Forge talk (Post)}
In a recent project with SoftMotion 4.15.0.0, where I integrated two SD drives from CMZ (from catalogue EDS and not imported), on CANopen bus, I found that the SoftMotion MC_Reset function does not reset the drive faults. Even if the drive is in fault, either on the device or on the drive at the CoDeSys level, the function does not reset, instead reporting the error code: no error to reset. Finally, I had to connect the reset bit of the ControlWord directly to a tag in my program. Something I never had to do on other drives: Lexium, etc. all reset simply with MC_Reset.

Hallo … ich verwende: SoftMotionLight im Positions-Mode Ethercat-Bus Servoverstärker: Metronix BL4104-C . MC_HALT_SML funktioniert nicht zuverlässig (Achse fährt manchmal zu weit oder bis zum Softwareschalter) Ich habe festgestellt, dass intern beim Aufruf von Positions- auf Velocity-Mode umgeschaltet wird - und dann wird wahrscheinlich intern auf Drehzahl 0 abgeregelt. Kennt jemand dieses Problem? – der Wechsel der Betriebsart ja ist nicht verzögerungsfrei! MC_STOP_SML Der Baustein hat keinen Eingangsparameter "Deceleration" Die Achse stoppt und bleibt im Positions-Mode. Aber die Verzögerung ist nicht wie beschrieben: nicht "Objekt 6085h: quick_stop_deceleration" - sondern "Objekt 6084h: profile_deceleration" - aus zuvor aufgerufenem MC_MOVE_ABSOLUTE_SML Ich wäre dankbar für jeden Hinweis Gruß Bernhard

Liebe Forumsteilnehmer, hat jemand schon die Beckhoff-Multi-Klemme EL8601-8411 am EK1100 zusammen mit dem Raspberry Pi verwendet? Ich bin gerade am Testen und habe festgestellt - dass das mit dem Einstecken der Geräte nur teilweise funktioniert. - DI/DO und AI(U) lässt sich benutzen. - Den Zähler kann ich nicht testen, weil das Gerät nicht einsteckbar ist. Ich kann es zwar einstecken, aber dann läuft der Bus nicht. - Beim Encodereingang fehlt mir vermutlich ein geeigneter Funktionsbaustein um den zu betreiben. Gibts da evtl. irgendwo eine Bibliothek? Ich benutze CODESYS V3.5.19.70, habe die neuesten Gerätedateien (XML) von Beckhoff eingespielt und für den Raspberry Pi benutze ich die Version Codesys Control for Raspberry Pi 4.14. Für Antworten bedanke ich mich schon mal herzlich VG A. Hofer

Post by abuckie on Getting raw value as full resolution for ADS1115 ^{CODESYS Forge talk (Post)}
I just found this and I am getting a value larger than 16 bit, around 81000 something. I am reading a 5 volt value and I am using level shifters for the i2c bus. This is how I have the channel configured: ADS1115.usiAddress := 16#48; ADS1115.ChannelConfigs[0].Active := TRUE; ADS1115.ChannelConfigs[0].PGA := FSR_6144mV; ADS1115.ChannelConfigs[0].InputMux := Single_0; RawAnalogValue := ADS1115.Channels[0].Value; It looks like every value is a multiple of 3. Any idea where to look to fix this? I think i found what I want to change in UpdateChannels Channels[FChannelNo].Value := INT_TO_REAL(WORD_TO_INT(LValue) * GetFullScaleRange(ChannelConfigs[FChannelNo].PGA)) / 2048.0; I try to edit it but I can't, sorry if this is a basic question, I am new to CODESYS.

Hi, I want to use two OneWireMaster on a Raspberry Pi5. I'm running Codesys Control for Raspberry Pi 64SL V 4.15.0.0. Under Linux I've configured two GPIOs for 1w bus usage on GPIO4 and GPIO27. Under Linux both masters seem to work fine and I can readout both sensors connected to both GPIOs. The two masters are 'w1_bus_master1' and 'w1_bus_master2'. In Codesys I've configured to OneWireMasters with the corresponding file paths. But in Codesys the 2nd onewiremaster "w1_bus_master2" doesn't work. Status is showing "OnewireMaster : Not running" What am I doing wrong? Does Codesys on Raspberry support multiple OneWireMasters? Any help is appreciated.

Post by timvh on Profinet fault with codesys control V3 - Receive packet error ^{CODESYS Forge talk (Post)}
Are you using the Control Win SL (installed together with the development environment of CODESYS)? If yes, you might want to consider using the CODESYS RTE instead. This has real-time capabilities (running on separate core(s)). But to be able to use this, you have to install the CODESYS Ethernet driver for your network interface to be able to let the RTE access the network port also in realtime. See: https://store.codesys.com/en/codesys-control-rte-sl-bundle.html https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_windows_rts_v3.html PS, I haven't tested this myself yet, but you could try to use the SetCommunicationState method of the Profinet controller to see if you can reset and start the bus communication: result := PN_Controller.SetCommunicationState(eRequestedState := DED.DEVICE_TRANSITION_STATE.START); PS, if you are located in the Netherlands or Belgium, we could also provide the license(s) for you.

Post by vernon-laurence on EtherCAT fieldbus ^{CODESYS Forge talk (Post)}
The simplest way to do this would be to add a bus coupler dedicated to the expansion IO. The EtherCAT network does not fault when modules connected to the expander are not present. In the image below, nothing below the red line is present in the network - with the network working correctly. In your "base" project, simply include all of the possible modules, and then plug them in as you add pumps to the system. I would also highly recommend against the use of direct addressing. There are other methods to accomplish this, including using the "Optional" checkbox for modules and explicitly addressing them. Although, this would require more upfront work to design the network, and some additional work each time modules were added. https://content.helpme-codesys.com/en/CODESYS%20EtherCAT/_ecat_edt_slave_slave.html

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 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.

Post by paulorb on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
Hi I am trying to use STRUCT to parse commands from Modbus/TCP, Modbus client will fill the bytes related to a specific command (type, parameters), then PLC (Codesys) will access the command parameters. A STRUCT will simplify a lot the process of parsing the data, so I don't need to parse byte per byte, address will be mapped to a struct and I can use it for parsing the data. From what I understood, the compiler does not allow me to specify the location of the struct for a %MW register. VAR_COMMAND AT %MW1002: structGenericModbusCommand; This will throw: Bad declaration, use '%ML' for 'structGenericModbusCommand' variable But If I change it to %ML, when you go online you see that it is actually allocating the struct in another memory address. When we go online, on GVL we can see: VAR_COMMAND. structGenericModbusCommand %ML1002 commandType COMMANDTYPE %MB8016 ... %MB8020 I am not specifying a pointer or a reference it is a struct type, why is it mapping to a %MW location (random one). How can I control where it is mapping to? I need a consistent way to map STRUCT to specific modbus address. Is it possible? Thanks, Paulo Note I am using a Codesys OEM: Schneider Machine Expert Logic Builder (M241)

Post by elektron785 on GPIO mit Codesys Virtual Control for Linux ARM64 SL ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich möchte an einem Entwicklungsboard auf dem der i.MX 8M Plus von NXP aufgesteckt ist die vier zur Verfügung gestellten GPIOs als Ausgänge verwenden. Ich habe mir dazu die Readme-Datei des GPIO-Beispiels von "C:\Program Files\CODESYS 3.5.20.40\CODESYS\CODESYS Control SL Extension Package\4.14.0.0\Examples\GPIO" angeschaut Die Übersicht der verfügbaren GPIOs sieht folgendermaßen aus - wobei ich das auf die reduziert habe, die für mich von Interesse sind: gpiochip0: GPIOs 0-31, parent: platform/30200000.gpio, 30200000.gpio: gpio-0 (SODIMM206 ) gpio-1 (SODIMM208 ) gpio-2 ( ) gpio-3 ( ) gpio-4 ( |sd-vsel ) out hi gpio-5 (SODIMM210 ) gpio-6 (SODIMM212 ) gpio-7 (SODIMM216 ) gpio-8 (SODIMM218 ) gpio-9 ( ) gpio-10 ( ) gpio-11 (SODIMM16 ) gpio-12 (SODIMM155 |regulator-usb1-vbus ) out lo gpio-13 (SODIMM157 ) gpio-14 (SODIMM185 |regulator-usb2-vbus ) out hi gpio-15 (SODIMM91 )** Füge ich nun das GPIO (1 Bit)-Gerät in meinem Codesys-Programm hinzu funktioniert der Bus solange bis ich die Richtung in den GPIO-Parametern von "not used" auf "Output" stelle (siehe Bild gpio_parameter). Dann funktioniert nach Download der Bus nicht mehr. Gibt es noch eine andere Möglichkeit das zu steuern oder muss ich noch Einstellungen tätigen? Für die Zeile mit dem echo (export/unexport) aus dem Beispiel fehlen mir trotz sudo die Zugriffsrechte. "The Kernel Linux has deprecated GPIO user space SysFS. However, the kernel config CONFIGGPIOSYSFS is still enabled on Toradex's BSP to support customers using it in their legacy applications. You can check the configuration by running zcat /proc/config.gz | grep CONFIGGPIOSYSFS. For GPIO access from userspace, the new char device API, also known as libgpiod, must be used." Dies steht in der Verwendung der GPIOs - eine Ausführung des zcat-Kommandos liefert ein =y zurück.
