I have a device CAADiagDeviceDefault: IoConfig_Globals.Axis_A In our library, we perform introspection of the Etc_SlaveDiag. In that case, we have connectors, and by searching for them by address, I can find them in the IO mapping using the offset and size provided by EtherCAT. However, a Lenze i700 drive, instead of placing the IO mapping in the Etc_SlaveDiag device, places it in a sub-device CAADiagDeviceDefault. So, when I perform introspection, I cannot find the IO correspondences. Yet, in the CAADiagDeviceDefault, I do not find the connectors and cannot do the matching. Is there a way with a pointer or reference to a CAADiagDeviceDefault to obtain the address of the first input and the address of the first output? This is because we have our own motion library with many EtherCAT devices that automatically configure the mappings, but I can't manage to do so with the Lenze i700.

Hi After much trail and error I think I found the root cause to my OPC UA problem. The problem is that I cannot manage to build and download a program with a a custom OPC UA Information model. We use a Weidmueller WL2000 PLS, but the problem also exsist on the Win V3 PLC. Our custom information model is based on the latest versions of the OPC UA Core Nodeset v 1.05.03 (2023-09-20) and UA/DI nodeset 1.04.0 (2022-11-03) Those nodesets are installed in the Codesys Information Model Repository (3.5.19.6) However, when trying to build I get the following error. [ERROR] Untitled1: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/ is required by http://bos.org/ with a minimal publication date from 15.12.2023 but the device has only a model from 15.09.2021 installed. Probably the information model from 15.09.2021 is missing in the information model repository. [ERROR] Untitled1: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/DI/ is required by http://bos.org/ with a minimal publication date from 03.11.2022 but the device has only a model from 09.03.2021 installed. Probably the information model from 09.03.2021 is missing in the information model repository. Build complete -- 2 errors, 1 warnings : No download possible I think the problem is that the UA Core nodeset is implemented in the PLC firmware (at least that in Siemens S7), and that only includes the "old" nodeset from 2021-09-21 etc. So the question is, how (or if?) can I transfer the new nodeset to the PLS? I have created separate Information models under Communication manager with the newer code nodesets (UA and DI). But it seems that the compiler does not recognize them being excising, neither in the Codesys IDE or on the PLC. Would have guessed that this is a common issue, sine many manufacturers use the latest versions of the OPC UA standard, and that it would be a solution to the problem.

Post by paulg on RasPi CAA Serial example - unexpected behavior during debug
CODESYS Forge
talk
(Post)
I've trimmed down the CAA Serial Codesys example to only listen on one port but, when stepping through the Case structure in debug mode, it jumps out of the structure during a specific point in every scan (I'll point it out below after describing the setup and listing the code). I'm using a Pi 4 Model B, and I have an Arduino Nano Every plugged in via USB which is streaming the following serial message at 1 Hz: Time since opening connection: 1 s Time since opening connection: 2 s ...and so on. The Pi shows the Nano at /dev/ttyACM0 so I edited CODESYSControl_User.cfg to read: Linux.Devicefile=/dev/ttyACM The code in my PLC_PRG is (ignore some of the comments, I hadn't deleted them out from the original example): PROGRAM PLC_PRG VAR xStartTest : BOOL:= TRUE; iState : INT; xTestDone : BOOL;(* True, when the test was done succesfully *) (* Settings to communicate with the COM Port *) aCom1Params : ARRAY [1..7] OF COM.PARAMETER; como1 : COM.Open; comc1 : COM.Close; comw1 : COM.Write; comr1 : COM.Read; //sWrite : STRING := 'Test String!'; sRead : STRING(25); szRead : CAA.SIZE; xCom1OpenError : BOOL; xCom1CloseError : BOOL; xCom1WriteError : BOOL; xCom1ReadError : BOOL; END_VAR //This example shows the communication of two COM Ports with each other. //The first one writes a string of characters, which is read by the second one. //After successful execution, the two COM Ports are closed and the test is done. IF xStartTest THEN CASE iState OF 0: //The parameters are set for the COM Port aCom1Params[1].udiParameterId := COM.CAA_Parameter_Constants.udiPort; aCom1Params[1].udiValue := 1; // the correct Port should be adapted aCom1Params[2].udiParameterId := COM.CAA_Parameter_Constants.udiBaudrate; aCom1Params[2].udiValue := 115200; aCom1Params[3].udiParameterId := COM.CAA_Parameter_Constants.udiParity; aCom1Params[3].udiValue := INT_TO_UDINT(COM.PARITY.NONE); aCom1Params[4].udiParameterId := COM.CAA_Parameter_Constants.udiStopBits; aCom1Params[4].udiValue := INT_TO_UDINT(COM.STOPBIT.ONESTOPBIT); aCom1Params[5].udiParameterId := COM.CAA_Parameter_Constants.udiTimeout; aCom1Params[5].udiValue := 0; aCom1Params[6].udiParameterId := COM.CAA_Parameter_Constants.udiByteSize; aCom1Params[6].udiValue := 8; aCom1Params[7].udiParameterId := COM.CAA_Parameter_Constants.udiBinary; aCom1Params[7].udiValue := 0; //The first Port is opened with the given parameters como1(xExecute := TRUE, usiListLength:=SIZEOF(aCom1Params)/SIZEOF(COM.PARAMETER),pParameterList:= ADR(aCom1Params)); IF como1.xError THEN xCom1OpenError := TRUE; iState := 1000; END_IF //After a successful opening, the next state is reached IF como1.xDone THEN iState := 15; END_IF 15: // the reading process is started comr1(xExecute := TRUE,hCom:= como1.hCom, pBuffer:= ADR(sRead), szBuffer:= SIZEOF(sRead)); IF comr1.xError THEN xCom1ReadError := TRUE; END_IF //After completion the size of the written bytes are saved IF comr1.xDone OR comr1.xError THEN szRead := comr1.szSize; iState := 20; END_IF 20: // If everything was successful the ports are closed and the handles are released comc1(xExecute := TRUE,hCom:= como1.hCom); IF comc1.xError THEN xCom1CloseError := TRUE; END_IF IF comc1.xDone OR comc1.xError THEN iState := 25; END_IF 25: // The first port is closed and the used handle released xTestDone := TRUE; xStartTest := FALSE; iState := 0; como1(xExecute := FALSE); comw1(xExecute := FALSE); comc1(xExecute := FALSE); ELSE iState := 0; END_CASE END_IF I realize as I write this that the .udiPort should be 0 and not 1, but that shouldn't be causing the issue I'm seeing. I'm forcing xStartTest:=TRUE every scan so that I can step into each line and observe what's happening. What I see is that the port parameters are set and the port is opened with no errors, but the code jumps out of the case structure to the last line every time it reaches (and I step into) the iState:=15 line (at the end of the iState:=0 block). So every scan cycle it goes through the block for iState=0 and jumps out at the same spot. I'm a little new to PLC programming so I may be misunderstanding the flow, but shouldn't this case structure keep moving down in the same scan? If it only handles one case per scan, why doesn't the value of iState persist? Thanks! Update: I restarted the Codesys control today and I was then able to see an error for como1.eError of "WRONG_PARAMETER". I tried doing some digging and another post made me think I should add another line to CODESYSControl_User.cfg, so I now have: [SysCom] Linux.Devicefile=/dev/ttyACM portnum := COM.SysCom.SYS_COMPORT1 So now when I set .udiPort to 1, I get "NO_ERROR" but I also don't read anything from the port (i.e. szRead = 0 always). If I try setting the port to 0 (which I'm confused about, because I added a COMPORT1 line but the device shows on the Pi as ACM0), I get the "WRONG_PARAMETER" error again. Is there an easier way to troubleshoot the Pi and view what ports the Codesys runtime is actually able to see while the Pi is running?

Good day All I would like to share some information on this site for the Codesys team as well for the future members using Codesys Control for PLCnext if it is allowed. I hope that i Post it in the correct spot. Subject: Codesys, Codesys Control for PLCnext Objective: Using the following Phoenix components to built a PLC Rack and run it on Codesys: Hardware and Software used 1. 2404267, AXC F 2152 - Controller 2. 1088136, AXL F BP SE6 - Module carrier 3. 1088129, AXL SE DO16/1 - Digital module 4. 1337224, AXL SE PD16 GND - Potential distributors 5. 1088127, AXL SE DI16/1 - Digital module 6. 1337223, AXL SE PD16 24V - Potential distributors 7. 1088123, AXL SE AO4 I 4-20 - Analog module 8. 1088134, AXL SE SC-A - Cover 9. Codesys v3.5 SP19 Patch 4 10. Codesys Control for PLCnext V4.10.0.0 Process: Firstly I built the Rack according to the Phoenix Project+ Software tool. Where I rebuilt it onto my test bench . I used the PLCnext Engineer IDE from Phoenix and all Communications where up and running and my PLC program executed successfully. THEN I tried the same PLC Layout with Codesys and Codesys Control for PLCnext. It was not successful and gave me the "Error: Local Bus not Running". I searched the web for answers but was unsuccessful in finding a solution. So I tried to change my configuration and found that the following Modules COULD NOT be recognized by Codesys Control.

I just installed codesys runtime on a raspberry pi Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz (Compute Module 4) I am running on Codesys control for raspberry pi 64 SL ver 4.13.0 and I keep getting a crash after about five to ten minutes. This program was running fine on a 32bit system with runtime 4.8 previously but they upgraded the panel PC cause it got smashed. Looking at the logs I see this error "ERROR: GetNetLinkSockAndInfoByMac(): could not open netlink socket: Too many open files" at the time of crash. I do have a UDP socket open for a serial to ethernet adapter and im wondering if maybe its opening a bunch of sockets and while receiving messages, Im not sending anything to the device only receiving. Below is the code used for the UDP VAR // Scale Comm fbPeerServer : NBS.UDP_Peer; ipAddress : NBS.IPv4Address; fbReceive : NBS.UDP_Receive; xPeerActiv : BOOL := TRUE; abyReceive : ARRAY [0..255] OF BYTE; sLastValidReceive : STRING(255); udiIndex : UDINT; END_VAR IF xPeerActiv AND NOT fbPeerServer.xBusy THEN ipAddress.SetInitialValue(ipAddress := gvlSettings.sIPAddres); fbPeerServer(xEnable := TRUE, itfIPAddress := ipAddress, uiPort := gvlSettings.uiPort); END_IF fbPeerServer(); fbReceive(xEnable := fbPeerServer.xBusy, itfPeer := fbPeerServer, pData := ADR(abyReceive), udiSize := SIZEOF(abyReceive)); IF fbReceive.udiCount > 0 THEN IF fbReceive.udiCount < SIZEOF(sLastValidReceive) THEN SysMem.SysMemCpy(pDest := ADR(sLastValidReceive), pSrc := ADR(abyReceive), udiCount := fbReceive.udiCount); // Set End of String sLastValidReceive[fbReceive.udiCount] := 0; END_IF END_IF If anyone as seen this I could really use some help figuring it out.

Hi TK_Jenssen did you found a solution I am setting up the samelike gantry only with two z-axes which are mounted on fix position with an X axes between the two z-axes. The movement and position of both z-axes must be very well aligned and calibrated. Maybe also to be adjusted by programming. Can you sent an example of your solution?

When using the FileOpenSave dialog and using the Visu_FbFileListProvider FB as an In/Output I could not manage to detect the difference of pressing the "Load" button on the dialog vs. pressing the "Cancel" button. In both cases, the selected file is updated if the dialog is closed when checking using the Visu_FbFileListProvider.GetSelectedFileName() command. How can I prevent reading or writing of a file when the "Cancel" button was pressed?

SOLVED!!! In this imx8 max_cstate=1 in kernel boot parameters is not working! We found a workaround: #include <stdio.h> #include <fcntl.h> #include <unistd.h> #include <stdint.h> int main(void) { int fd; uint32_t value = 0; fd = open("/dev/cpu_dma_latency", O_WRONLY); if (fd < 0) { perror("Error opening /dev/cpu_dma_latency"); return 1; } if (write(fd, &value, sizeof(value)) != sizeof(value)) { perror("Error writing to /dev/cpu_dma_latency"); close(fd); return 1; } while (1) { pause(); } } This simple code launched before CODESYS do the same work! Now jitter is identical as measured by cyclictest!

If I do online monitoring of code in f.i. a function block, I cannot see if the function block is called or not. In software from other vendors you normally have an indication if the online code you are looking on is scanned at that moment or not. Is there a way in Codesys to determine in the online view if (parts) of the code are scanned or not? Thanks

Hello @eschwellinger, Why not using one of those 2 folders: C:\ProgramData\CODESYS C:\Users\Public\Documents\CODESYS The main reason is depending on the company and the user right, the end user may not have the access to use those folders. Also having a non version dependent folder may help if the end user uninstall a previous version and forgot all its sample project where in this previous version installation. Thanks.

I have developped a function block 'Axis' the inherits from 'AXIS_REF_SM3' -> FUNCTION_BLOCK Axis EXTENDS AXIS_REF_SM3 In my global variable list I define a variable MasterDrive of type Axis and assign Axis1. Axis1 is a virtual drive (AXIS_REF_VIRTUAL_SM3). This type should inherit from AXIS_REF_VIRTUAL. VAR_GLOBAL MasterDrive : Axis := Axis1; However I get the error 'Cannot convert type'. What is the way to obtain what I want : function block inheriting AXIS_REF_SM3 and initialising this function block with a Softmotion virtual or real axis?

There are some ways. One is to use SHR and SHL and it depends on your byte order in the data array. For Motorola byte order: PROGRAM PLC_PRG VAR u : UINT; byte_array_in : ARRAY [1..8] OF BYTE := [16#11, 16#12, 16#13, 16#14, 16#15, 16#16, 16#17]; byte_array_out : ARRAY [1..8] OF BYTE; END_VAR u := SHL(TO_UINT(byte_array_in[2]), 8) + TO_UINT(byte_array_in[1]); byte_array_out[1] := TO_BYTE(u); byte_array_out[2] := TO_BYTE(SHR(u, 8)); If it's Intel byte order just change 1 and 2 in the array indexes.

Hello, We encountered the same issues on both recipe library versions 4.2.0.0 and the newest 4.3.0.0. The Arrays of structs get saved correctly but loading them restores only some indexes, while others get lost or completely wrong. We have been using the same recipes for the last two years on recipe manager vers. 3.5.17 withoud issues. There also seems to be a different behaviour in vers. 4.3.0.0 but it's still incorrectly loading the recipes. Did you find any workaround or solution? Codesys version used: 3.5.19.50

the TCA9548a does not work in Codesys. In Pyton this is only queried once and in Codesys cyclically. Of course you can also insert a terminating resistor in each port, then you should have no problems. I use this one: https://botland.de/8-bit-multiplexer/12723-qwiic-mux-breakout-8-kanal-modul-mit-i2c-multiplexer-tca9548a-sparkfun-bob-16784-5904422341428.html You can simply set the library to the latest version. You do not need Oscat. Do you need an example project for the BMP280?
