AFAIK it just means, that the interrupts are not calculated on those CPUs. When the other CPU(s) are not blocked, and have enough time, it has no negative effect on the interrupt performance. It might even have positive effects, as interrupts are not blocked by high priority realtime tasks of CODESYS. So this setup sounds really great!
Hi Rafael, sadly not. The files contain mainly generated machine code. So you can't really see the difference between the projects from the binary files. Cheers, Ingo
I can agree with Tim. This is the problem. But when changing the pack mode, your program will not work on all controllers. For instance, when you have an ARM CPU, with a bit bad luck at the way the memory is connected, it is likely, that your DINT will not be correctly copied, when the memory is not aligned. So I really can't recommend to use this pragma, if you don't know exactly what you are doing. I think you can say, that only in two cases, this is no problem: you access the memory only with...

Please let us take part. Because the solution sounds fairly simple. What did you need to do manually, and is so much work?
gateway configuration for successful device scan
Please use CODESYS Talk for such questions
I agree with m.prestel. As you didn't write with which PLC you tried it, I would recommend to test it with the Control Win Soft PLC under windows. This way you can prove, that you did everything right in your project. If it doesn't work on the target, it would be interesting, which target that is. Cheers, Ingo
No tutorial I know of. But AFAIK the GPIO driver, which is included fits for all analog and digital GPIOs, which are accessible through the sysfs. And other external busses, like ethernet or CAN should also work, when there is a linux driver for the device. Cheers, Ingo necatibilgin forge@codesys.com schrieb am Sa., 11.

Trend auto axis not working with exception values
This is a question for CODESYS Talk
Hi! Those events are scanned in the Scheduler interval, which is by default 1ms on most systems. But those events are not useful for fast reactions. Some systems provide so called "external events". Those can be better compared with " interrupt handlers". But the raspi has no support for that. Your only chance is a quick cyclic task, in which you execute your code. Cheers, Ingo
Hi Guilherme! You may have more luck, getting an anwers, when you ask your question in CODESYS Talk
skip compile-library step, as this doesn't work atm
Currently I know no real successor. But (as a teaser) for SP18 I saw already concepts for defining constants per FB instance. With this it will be possible to scale buffers for each FB instance. I believe that this will substitute most uses for library parameters in a much better way.
Control Loop Library - no source code available
Hi Martin, sorry, but this question is not CODESYS Forge related. Maybe you want to ask this question in CODESYS Talk?
AFAIK the IEC61131 standard defines, that all variables are 0 initialized. It's more or less the other way around. You can define noinit if you want to avoid this initialization.

Did you try to define a watchdog for the task? Usually an expired watchdog should show you the endless loop: https://www.youtube.com/watch?v=Aeihipp6U4I
Hey! Very good idea. Sure, you can do it like that. I don't know why I didn't come up with that. Because, this is the most straight use-case for union 😉

Maximum screenshot limit
Hi! Sadly this is not that easily possible. Allura has a fix limit for the screenshots. This is not configurable: if len(screenshots) >= 6: flash('You may not have more than 6 screenshots per project.', 'error')
Unfortunately this is right at the moment. Seems like this feature for "Allura" (the underlying framework of forge) was never fully adapted to CODESYS Forge. For the moment: When somebody has a problem, please initiate the export, and ask here to get a link to it. We'll check, if you have the rights, and provide you the export.

OK, then you need to glue them into an LINT or DWORD first. The "glueing" is actually a shift left, by 16Bit, and an OR of the two types. The shift is necessary to move the bits of the upper to bytes to the correct position. And the OR "merges" the two datatypes into one. With an implicite 32 bit intermediate value: real3 := TO_REAL(SHL(int2, 16) OR int1); And if you want to make it very explicit: dword4 := SHL(int2, 16); dword4 := dword4 OR int1; real3 := TO_REAL(dword4);
Do you mean...? real3 := TO_REAL(int2 - int1); Didn't understand what exactly you meant with "diff" type.
AFAIK it is not. Maybe a workaround: drive your GPIOs from one task only (double check this in the 'task deployment' view). Do this in an Event task, which you trigger from a cyclic task, but only when you want to use those GPIOs. This way you have control over, what's written to the GPIOs during runtime. The initialization is still done by the CODESYS driver, but then you are able to reconfigure them in your external application. Cheers, Ingo
You are right. I also already heavily searched for the correct post, but didn't find it. The problem seems to be in the linking of the posts. Keeping links between the posts and attachments was the most tricky part, when we migrated the forum. @eschwellinger do you have the old projects still around? Maybe you can at least upload them?

If your question is about python scripting, then this thread is totally the wrong place 😉 Maybe you want to explain your problem in more detail in the "Engineering" forum. But just in case, that I got your question right, here is a pointer: simimar to read_value, you can do a write: https://forge.codesys.com/tol/scripting/snippets/14/
Go to /var/opt/codesys and search for .User*.csv files. And for the future, you can disable it like this: https://youtu.be/9tfm0y_Bwis

make versions for CODESYS and EDGE overloadable
Hi Sven, thanks for your contribution! What you've done sounds interesting! I just want to please you to publish the source library, too. The whole CODESYS Forge platform is about open source and the community. So others should profit from your source code.
Hi! This actually can be very easy, when I got your question right 😉. I would intuitively use Write8, as you did. The interface is roughly: Write8(usiRegister, usiValue) So, to write your bit 4 to register 1, you need to call s.th. like this: // when you start counting with 1 // => 0000 1000 Write8(1, 16#8); // when you start counting with 0 // => 0001 0000 Write8(1, 16#10); Alternatively, you can write it in binary form, instead of hex: // when you start counting with 1 Write8(1, 2#00001000); //...
Hey, that's an amazing project. I'd be very proud, if parts of our software would make this beast move. Are you already using CODESYS in it, or is it a new modification, on which you are working? Regarding your question: You always need to return s.th. in IEC. So usually you return a BOOL, if you have nothing else to say. There is no such thing, like a void function. It doesn't also feel natural in IEC, as the function represents more or less its return value. When you return a resilt, you assign...

Hi! The tool doesn't support it. But you already figured out how to start it w/o any UI. So you just need to write a script, which acts as such as server, and executes the other scripts. To execute them, I'd recommend to import them and call a method from them. This can be done with native python. Cheers, Ingo

Sorry for the problems! Attachments are working again.
Thanks a lot for this report, and even tracking down the problem this far. I appreciate this!
I have only theoretical knowledge. But, what you need is a Socket CAN driver for your CAN device. The interface of the socket can driver then needs to be up, wehn the runtime starts. The rest should work, I guess.
It depends. First you need to know more about the exact format. Is it a 32bit IEEE floating point number, which is just packed into an array of 4 bytes? Then, s.th. like this: byValue : ARRAY OF BYTE; prValue : POINTER TO REAL; rValue : REAL; prValue := ADR(byValue); rValue := prValue^; Actually you use pointers to the data to cast it to the correct data type.

Hi Kodiac, which PLC are you using? I remember, that we had such a report with the Raspberry Pi. And there it seems to be related to the GPIO driver, which has timing issues, when it's called from different tasks.

PDO mapping parameters
Hello Beember, sorry to ask. But how is this question related to the MCP3008 driver? Maybe you wanted to ask this in CODESYS Talk!?
Hehe, super veranschaulicht mit dem KOP! 😉 Aber da verschiedene Leute unterschiedlich denken, noch meine Merkregel. In der Mathematik gilt immer Punkt vor Strich. Bei logischen ausdrücken gilt "und" vor "oder". Doch! Ich würde auch immer Klammern, und manchmal lieber verschachtelte IFs oder noch besser, mehrere IF Blöcke hintereinander nutzen. Denn das macht den Code schlicht besser lesbar, und man kann auch klarer kommentieren, was dieser komplexe Ausdruck überhaupt prüfen soll.
TCP Verbindungen haben einen recht langen Timeout. TCP/IP stacks können recht schnell reagieren, wenn man das Kabel zieht. Wenn die Verbindung aber irgendwo zwischendrin unterbrochen wird, merkt das der Stack recht spät. Ich weiß nicht ob das dein Problem ist. Aber das Symptom klingt danach, finde ich. Falls es das Problem ist, hilft m.E. nur wenn der Client die Verbindung neu aufbaut. Wie du das erreichen kannst, hängt natürlich vom Client ab.
DLL library issues
Hi tesla! This is a very good question. And it is not easy to answer. But actually there is no easy way to open a C-Library from a CODESYS application. PLC manufacturers can do this with the Runtime Toolkit, or you can use an own process, written in c, which opens the library and communicates with your CODESYS application via shared memory or sockets. But on the other hand, such questions should be asked and discussed on CODESYS Talk. So I will close that ticket.
