please tell us the exact error message from diagnostic. U can view it at devicetree in the node-element diagnostic from modbus-configuration. u also can activate the function auto-reconnect in master and increase a little bit the timeout and the repetition to male thw communication a little bit more robust

If my application does some kind of violation which makes it cast an exception it will trigger my real watchdog which results in a reboot. Unfortunately the log it seems only shows the boot sequence. Is it possible to see what happen before reboot?

Hello otdeveloper, I am very interested in this topic. I have been dedicated to IEC 61499 for some time and I would like to understand if the time has come to adopt it in the real world of automation or if it will continue to fill up research papers only.

Post by rmaas on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
Hi, Im not sure if this is what you mean, but i do succesfully use the IoDrvEthercatLib.ETCSlave.InputData and IoDrvEthercatLib.ETCSlave.OutputData to read from and write to beckhoff DI and DO cards. Very convenient as you can make an FB with an VAR_IN_OUT of type IoDrvEthercatLib.ETCSlave and only have to pass the slave reference... So i am not using .ETCSlave_Diag but .ETCSlave...

I'm searching a way to print several projects to PDF, in order to correct student exercises. I'm able to open the printing dialog box using system.commands["print", "print"].execute(). But I can't find the prompt names in order to complete the printing with the dialogs Do you have any way to do that?

Thank you for the response! It's a path I had already considered, however, while it has always worked for me on inputs, it doesn't on outputs, because if I enable the option to update all IOs at every scan, the IO tasks overwrite each other. However, I have found something very interesting which I am posting below.

Hello, I don't really know what my problem was, but it's working for me at the moment. All i did was to change my code because of some REAL_TO_INT conversions, like i wrote above. And later a complete new Pi setup (because of 64x support with 4.10.0.0 now).

I'll have a look at this, thanks. Do you maybe know why the C-integration doesn't work? I'm just curious because it was still some effort to create all these files. Ending up with a meaningless error feels very unsatisfying to me...

Post by durstloescher on Library Documentation DocScripting ^{CODESYS Forge talk (Post)}
Hi, I am currently creating a documentation for our library with DocScripting. In the process, I noticed that Visu images are created before the merge and transform, i.e. "screenshots" of the different Visus. Unfortunately, these are not used in the later process (Merge/Transform). Is there a way to set it up so that they are found in the html file?

Damit wir nach einem neuen Raspberry Pi image die gleiche Lizenz für dieses Gerät brauchen können. Die Lizenz ist Geräte spezifisch so viel ich weiss. Bei unseren Geräten bei den Kunden hat es nicht immer eine Internetverbindung.

Dear Forum, I would like to initialize an array input on a method. When I do this, I get the following error: "The type of ARRAY [1..2] OF BOOL cannot have a default value in this context." I attached a picture for more clarity. Is this simply not possible or is there a different way of tackling this problem? Thank you in advance

Dear, We have an issue with SoftMotion and it's licensing. We don't use SoftMotion in this project. But a SoftMotion license is required by it. The License metrics tell's us there is a -1 Axes. Is there a way to reset this? Delete this? There was a MotionControl device in the project, but we have deleted this. But it stayed at -1. Thanks for you help.

Post by smartcoco on Dynamic object release issues ^{CODESYS Forge talk (Post)}
Dear, When I use "__NEW" to dynamically create the object "Object_1", and assign this object "Object_1" to another object "Object_2". At this point, I use "DELETE" to release the object from "Object_2". At this time, I cannot judge whether the object has been released normally through "Object_1" (in fact, the object has been released theoretically). Thanks for you help.

Post by timvh on Limiting Memory Access of an Array to Within its Bounds ^{CODESYS Forge talk (Post)}
Add the object "POU for Implicit Checks" to your application, then select "Bounds check". This will create a function which is automatically called each time an array is write accessed. In the function you can handle "out of bounds" situations. By default it will be limited to its lower or upper bound.

Post by fless on How to change bHiresMode ^{CODESYS Forge talk (Post)}
you need to set the increments to 10 (the screenshot shows 10000 hex = 65536). all the turn settings to 1. and the application units to 366. But usually you use the resolver resolution per motor turn. Insert the gear ratios (1:1 for no gear) and the last field you put the circumference of your drive wheel.

Hi, we did install the real-time kernel patch on the RPI and also performed the additional optimizations including isolating the cores. Changing the configuration of the planning task e.g. running it on a separate core, changing the cycle times and mode from cyclic to freewheeling did not show any improvements.

I've already experimented with two methods, but unfortunately, they only function with projects of type *.project. Consequently, when executing: system.commands["staticanalysis", "run"].execute() For the 2nd Option: You'll need to ensure that in the Static Analysis Settings, the option "Perform static analysis automatically after compilation" is checked. # get Project values myProject = projects.primary # Creates an active application app = myProject.active_application # build Application and run static code analysis app.generate_code()

Post by thewizard8 on Raspberry PI4 Serial Port ^{CODESYS Forge talk (Post)}
Hi All, I finally figured out how to solve it. The only away that I got it to work was to define parity to None on modbus configuration, and now works like a charm. Just for the record I'm using the GPIO port pins (8,10) and a RS485 to ttl shield that you can find online. Thanks all for the support! Regards Ricardo

One workaround is to create a second application which is started after the rested of the main application. The second application starts the main application after time x and is rest after done start of the main application. No problems during the fieldbus re-start by this workaround.

Wow.... I missed this one in the manual - so there is a special syntax to invalidate a reference... Great :) Seems to work. (it's just mentionned in the examples line)... I've always assigned 0 to the variable, with := 0 - like setting a pointer to 0. In theory, that should work as well. Thanks!

Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi all, I want to know if someone has an idea of how I can write on value change in Modbus Codesys. I have a Wago PLC and I was used to work with E-cockpit which it was quite easy to do that without the necessity to trigger any value when there was a change in the variable ( I will put how easy is ). how you can see just changing the trigger in "On value Change" will do that channel writing automatically when It detects a change in those arrays. On the other hand, in Codesys if I enable the rising edge in Codesys It ask me to put a bool variable and if triggers is going to write that value. That is making me that I have to create a function or a logic to detect the change, the problem I have is that doing that is very tedious. I first approach I got it was to create a Function who returns a bool when the value change, but I tried to keep the old value but what is happening is that in Functions all the data is erased every cycle so I can not keep any Old value. so in the Main program the trigger is going to be TRUE all the time due, the old value is cero every cycle. The second approach I got it was using a function Block (POU_1) and it works but I dont want to instance that function for every Channel or value that I want to check if the value change, Basically if I have 200 values to write trhough modbus I have to create 200 instances of that function which I think it is not practicall at all. It should be a better way to implement this as e-Cockpit from Wago Does. However, I haven't been able to know how.
