Hi, I guess you don't have the right xml file. Download Beckhoff_EtherCAT_BKxxx_MDP.zip from https://download.beckhoff.com/download/configuration-files/io/ethercat/xml-device-description and install these in Device Repository.

thank you, i tried your library and device description but i don't get analog values. Do i something wrong? i also got an library error at the I2C_BASE functionblock the calcCycleTime gave an variable size error, so i added thet conversion from ULINT_TO_UDINT.

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
your driver is not running. All libraries must be present first! Then you can try the following. Delete the ADS1115 and the I2C_maseter from the device tree. Create everything again.

I also installed your codesys version with the codesys for raspberry pi package version 4.7.0. but with no succes, only the TCA multiplexer has a constant green turning circle, the ADS1115 still changing from running to not running.

Agree! Me and my customers are buying SL Licences from the store but we don't get proper documentation of the runtime! Only a few hints of the entries in CodesysControl.cfg are spread all over the Internet.

Same here. plcload in my case is about 7% while running. Watchdog ENIPScannerIOTask was about 200ms. Max cycle around 6ms, normal cycle time 4ms. Probably just increase the watchdog to 2000ms? or so... (Hardware: A Panel from Weintek)

Hi, again after spending a lot of time finding more information with no results, by chance I changed the device ID from 1 to 255 and the transmission works. Unfortunately the documentation is very very poor.

Given the response to your API request, I don't think this is a CODESYS issue. The response says ... Please provide a valid API token ... so you must get a valid API key from enever.nl

Post by jddaigle on A method in the Task Configurator ^{CODESYS Forge talk (Post)}
How is that possible to put a Function Block Method in the Task Configurator, as they did in the CNC3DEditor.project example? In that exmaple, I removed the gCNCMachine.SlowTaskCall method from the Task Configuration and I can't put it back. https://us.store.codesys.com/cnc-3d-editor.html Thanks!

You can download the missing libraries by clicking on the "Download Missing Libraries" button. However, if you were unaware of this and accidentally downloaded the latest version of the library from the Library Repository, you may need to uninstall it first to avoid conflicts.

Post by ojz0r on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
One thing you could do is create an object with the variable as field with a function and procedure to get the variable (read) and set the variable (write). These are then called from your program and the vizualization.

Solution: VAR itfAlarmConfig: AlarmManager.IAlarmConfiguration; itfAlarmConfig7: AlarmManager.IAlarmConfiguration7; SCRIPT itfAlarmConfig := AlarmGlobals.g_AlarmHandler.GetAlarmConfiguration(0); IF __QUERYINTERFACE(itfAlarmConfig, itfAlarmConfig7) THEN itfAlarmConfig7.ClearHistory(FALSE); END_IF Works perfectly for me.

Post by pernockham on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
Started playing with the idea of ditching windows for linux, one of the obstacles would be Codesys development. Alternatives: - linux with wine? - Run windows/codesys through virtual machine I guess a vm is the way to go? Anyone out there that could share their experience?

@eschwellinger - We are experiencing the exact same issue. RunTime 3.5.19.70 and IDE V3.5 SP21. It's 100% reproducible. All you have to do is disconnect the network cable for about 10 minutes. OPC UA Crashes and requires a reboot to fix.

It is not an error, but just an information message. You need to select the correct location in your device tree where you want to import the objects. E.g. select Application below your Device.

You can write any expression that evaluates to TRUE/FALSE in that property, you can also call a method from the property.

Post by mondinmr on Why SysPipeWindows is not implemented in RTE? ^{CODESYS Forge talk (Post)}
This library would be very useful for IPC communications. Using a UDP socket on localhost is unpredictable, as with slightly loaded machines it does not even guarantee packet delivery locally. Using TCP creates a lot of overhead. Message named pipes would be an excellent solution for Windows RTE. On Linux, since the release of the extension package, there is no issue, as it is sufficient to develop a component. However, although now 90% of our clients understand that Linux runtimes are better in every way compared to Windows RTE, especially from the security aspect (Not in kernel space) and the issues with Windows updates, 10% stubbornly insist (sometimes for trivial commercial reasons) on using Windows. Managing IPC with circular buffers in shared memory is quite ugly, or rather really ugly and unaesthetic. In the manuals, I saw the SysPipeWindows libraries, so I decided to test them, but unfortunately, I noticed that they are not implemented for RTE devices. Technically, I could try to open them as regular files, but SysFileOpen returns 16#27 or 16#39 depending on how I set the name (direction of the slashes). Here is the code to create shared memory and named pipes. Shared memory work great, named pipes no! #ifdef Q_OS_WIN32 SECURITY_ATTRIBUTES sa; SECURITY_DESCRIPTOR sd; InitializeSecurityDescriptor(&sd, SECURITY_DESCRIPTOR_REVISION); SetSecurityDescriptorDacl(&sd, TRUE, NULL, FALSE); sa.nLength = sizeof(SECURITY_ATTRIBUTES); sa.lpSecurityDescriptor = &sd; sa.bInheritHandle = FALSE; const wchar_t* name = L"Global\\ShmTest"; HANDLE hMapFile = CreateFileMapping( INVALID_HANDLE_VALUE, NULL, PAGE_READWRITE, 0, sizeof(SharedData), name); if (hMapFile == NULL) { qCritical("Error creating shared memory"); return 1; } data = static_cast<SharedData*>(MapViewOfFile(hMapFile, FILE_MAP_ALL_ACCESS, 0, 0, sizeof(SharedData))); if (data == NULL) { qCritical("Error mapping shared memory"); return 1; } HANDLE hPipe = CreateNamedPipe( TEXT("\\\\.\\pipe\\MyPipe"), PIPE_ACCESS_DUPLEX, PIPE_TYPE_MESSAGE | PIPE_READMODE_MESSAGE | PIPE_WAIT, PIPE_UNLIMITED_INSTANCES, 1024 * 1024, 1024 * 1024, NMPWAIT_USE_DEFAULT_WAIT, &sa); if (hPipe == INVALID_HANDLE_VALUE) { qCritical("Error creating named pipe"); return -1; } if (!ConnectNamedPipe(hPipe, NULL)) { qCritical("Error connecting to named pipe"); return -1; } checkPipe(hPipe); #endif

Post by garyl on Comments in arrays and assigning RST coil's to 600 outputs ^{CODESYS Forge talk (Post)}
Hello all, im working on a project that requires me to convert an old automation direct DirectSoft PLC d2-250-1. One of the problems im encountering is that all of the comments are attached to members of the different addresses. When i convert the addresses (1777 "C" registers, 777 X registers, and 20,0000 V registers) im running into difficulties keeping the inputs/outputs correct since they are missing documentation. Is there a good way to retain the comments of the indexes in the array? Secondly, initially i was declaring the "C" and "V" addresses individually and this worked to retain the comments as to which register did what, however i ran into a problem when one rung reset (or set to 0) approximately 600 C Addresses. Since each tag is separately declared this proved to be nearly impossible without a literal wall of code that attempted to crash the program. So i converted all of the registers (C,X,Y,V) into separate structs, declared them as arrays and pointed all of the original call outs in the program to the newly defined structs. However i have now lost comments and the program is very hard to follow. Thanks for any help with this issue.

Post by dhumphries on Minimum system requirements for codesys control standard S ^{CODESYS Forge talk (Post)}
I'm working on a low cost project and I'm considering installing the Codesys runtime on a PC running Linux Debian instead of buying a PLC with a pre-installed runtime. For my needs the Control Standard S license should be capable of running some IO over ethernet/ip, and a webvisu. The PC I am considering has a AMD GX-424CC 2.4GHz processor (4 core/4 thread) and 4GB RAM. This may compare to a raspberry pi4, but I know an X86 processor doesn't directly compare to an ARM processor, and a processor can have a high clock speed but other factors like L2/L3 cache can influence the overall performance. I can't find any published specs for the processor and RAM requirements to run the Codesys Control runtime, does anybody have a link to the minimum system requirements or experience using devices that are at or below the minimum system requirements. A raspberry pi with the control for raspberry pi SL runtime license would be the lowest cost option, but the license is not for commerical use. This restriction is somewhat vague, can anybody clarify if this means I can use a raspberry Pi runtime for in-house automation, what about if I am selling an integrated system that uses a raspberry Pi as a controller?
