Post by sturmghost on Visualization using methods and cyclic ST-calls ^{CODESYS Forge talk (Post)}
I found a way to do it: You can use, for example, the text variable property of any visualization element and call a function in it. Example: Write a test POU as a function (FUN), like MyTestFun which need a boolean Variable as an input value. Now write into the text variable property: MyTestFun(bBooleanValue) Thats it. The function is called at each visu_task cycle.

Post by sturmghost on Find visualization elements that require a lot of computing time ^{CODESYS Forge talk (Post)}
I found out that the Codesys simulation mode is not good to measure performance. As soon as I upload the code onto the hardware PLC I can see that my visu-task needs around 60 ms to complete. I'm wondering if there is a possibility to find out which visualization/visualization element takes a lot of computing time? Then I would look for ways to decrease the long computing time.

I'm getting this error on one of my projects. Searching for it I came across this https://www.codesys.com/fileadmin/data/Images/System/Releaseinformation/Patch-Note-CODESYS-Visualization-4300.html which says it was a bug VIS-1394, fixed in Visualization 4.3.0.0. I'm using a previous visu version, what is the cause of this error, and what can be done to work around it?

Hello, I'm new here so if I do something wrong please bare with me. I am using raspberry pi touchscreen made by comfile (CPi-C070WR4C). I also have a window 11 pc where I would like to have a second visualisation, but when I run a TargetVisu with it, all elements of the visualisation end up in the top left corner stacked on top of each other. I have same results running targetVisu on my laptop. Maybe someone had same issues and know the solution? Simas

Post by larboardinner on Alarm Table Issues ^{CODESYS Forge talk (Post)}
Variable for Selected Alarm ID only updates when the visualization is actually configured to send the alarm’s ID back to the control. On some devices/visualization profiles this isn’t enabled by default. Make sure your Alarm Table element has “Send Selected Alarm ID” activated in the visualization properties. you could check this example: https://store.codesys.com/alarm-manager.html Geometry Dash Lite If that option isn’t available in your version, then unfortunately the “Selected Alarm Group” is the only one that updates reliably in older 3.5.x builds.

Post by john-robinson on Limiting Memory Access of an Array to Within its Bounds ^{CODESYS Forge talk (Post)}
Recently we had an issue regarding some simple code to calculate a rolling average. The code indexes from zero to 199 to properly store the current input into a circular buffer which then allows us to calculate a rolling average: VAR input_5s : REAL; outs_arr : ARRAY[0..199] OF REAL; i : USINT := 0; END_VAR ___ //this code runs every five seconds, calculating a rolling average outs_arr[i] := input_5s; i := i + 1; output := OSCAT_BASIC.ARRAY_AVG(ADR(outs_arr), SIZEOF(outs_arr)); IF i >= SIZEOF(outs_arr) THEN i := 0; END_IF There is a simple bug in this code where the index will be set to 0 when it has surpassed the length of the array in bytes (800 in this case) rather than larger than the number of reals in the array (200). The solution here is simple, replacing i >= SIZEOF(outs_arr) with i >= SIZEOF(outs_arr)/SIZEOF(outs_arr[0]). In this example when the index increased to 201 and the line outs_arr[201] := input_5s was called, codesys arbitrarily wrote to the address in memory that is where outs_arr[201] would be if the array was that long. I would like to find a way to wrap the codesys array inside of a wrapper class that checks if an input is within the bounds of an array before writing to that value. I know how I would implement that for a specific array, I could create a method or class that takes an input of an array of variable length, ie. ARRAY[*] OF REAL, but I don't know how to make this for any data type. I am wondering if anyone has ever done anything similar to this, or has any better suggestions to ensure that none of the programmers on this application accidentally create code that can arbitrarily write to other locations in memory.

Post by mubeta on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
This is normal and correct since in CoDeSys static addressing of variables uses the IEC method. A LONG tag has the size of 8 bytes, so %ML0 coincides with %MB0 ... %MB7; %ML1000 with %MB8000 ... %MB8007. (Similar reason for word and other formats). Also the reason the compiler won't let you map the structure to a %MW depends on the fact that the individual base elements are manipulated to 64 bits regardless of the smaller size. That said, it makes me strange that you cannot write a parser without making use of static memory allocation.

Post by hismoon on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Using a UNION instead of a STRUCT alone should give you that flexibility and only occupy memory once. And if you want to be really elegant, you could use an FB, which only holds PUBLIC VAR. Because a POU can use "EXTENDS"/inheritance. In CODESYS V3, an FB has a lot in common with C++ classes. Using ANY or ALIAS is rarely a good idea. It neither won't be pretty, nor have good readability and requires you to create a lot of error-prone things around it.

Bonjour, La librairy est SYSMEM en Codesys v3.5. Pour accéder à la fonction : SysMem.SysMemSet. Il y a plein d'autres fonctions intéressantes : SysMemSwap, SysMemMove, SysmemCpy, ... Cela évite de créer des Boucles et permet de bien utiliser ADR() et SIZEOF() Il existe aussi une librairie CAA Memory qui mérite intérêt; Par exemple MEM.MemFill pour remplir un tableau d'octets. Bons développments! Il suffit d'ajouter ces bibliothèques dans le gestionnaire de bibliothèque pour les utiliser. JM

The generic sensor FB is for controlling the sensor via its cyclic input (PDI) and output (PDO). In this case, ifm raw cyclic input and output data are WORDs (16 bits total) The PDO data from the Buerkert unit are SINT (8 bits) In this case, I would use the unpackword fb from the CAA memory library to unpack the valve feed back value into the appropriate location.

Post by alexgooi on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi Duvan, You could make this in 1 single object (FB), Indeed don't use a function for this beacuse you need some memory to keep the old value. For i := 0 TO 200 BY 1 DO //Check if the value has been changed IF Old_Value[i] <> Value[i] THEN //Set the trigger to TRUE Trigger[i] := TRUE; Old_Value[i] := Value[i]; END_IF END_FOR If you define the Value array as an In_Out and the Trigger as an In_Out you arn't claiming any aditional memory to your system. You ofcourse then need to add some code arround it that does something with the trigger and writes it back to FALSE again. If you want more flexability you also could use pointers instead of using the IN_OUT FOR i := 0 TO 200 BY 1 DO address := address_Input + i * SIZEOF(*Put type here); IF Address^ <> Old_Value[i] THEN Trigger[i] := TRUE; Old_Value[i] := Address^; END_IF END_FOR

I would figure out, how to create a simple html webpage with 2 frames. One frame with buttons to select the plc. A second frame with hyperlink to the webvisu of the plc ("XXX.XXX.XXX.XXX:8080/webvisu.htm"). Selecting other PLC Button has to change the hyperlink in 2. frame. Costs only some time to figure out :-) Or setup a raspberry Pi with small visualization. Set up a button for each plc and add one browser element. Each button writes the URL of the depending plc to the URL setting of the browserelement. Costs 55€ for runtime licence and a Raspberry Pi.

hello everyone I would like to try to better understand how persistent variables work. I created some boolean variables in the PersistentVars section initialized to the value TRUE. I have tied these boolean variables to toggle switches placed inside the HMI interface pages. Once the PLC program is started, the lever selectors, if operated, change their state, at least at a graphical level, but the persistent variables do not undergo any variation. Initially the above variables were declared as simple global variables, in this case the operation with the levers was correct; I then tried to transform them into persistent ones with the aim of using them as "settings saver" Thank you for support Bye

the magic option is named "Use CurrentVisu variable" activate this option in the Visualization Manager an have a look: https://help.codesys.com/webapp/_visu_obj_manager;product=core_visualization;version=3.5.14.0 if your button is pressed, "feed" the string varable VisuElems.CurrentVisu := 'visu1'; with the correct name of the depending visu. alternative: place a frame element at a empty main visu, konfigure all visus to be shown by this frame. With setting the switching variable of the frame to the index value of the depending visu, it will switch to it. Advantage: the visu names are not hardcoded as string in the ladder lodgic. Good luck! Hint: If you have multiple VisuClients(Target, WebVisu,...) all will show the same visu. Independent switching is much more difficult, but there is a example from codesys.

But, it seems that are occurring some memory leak problem in a "high" frequency (more than 10 Hz) subscribe process. I follow the same method as in IoT Lib exemples, and at first looks perfect but my PLC was rebooting frequently and when I check its memory usage that was increasing as fast as the subscribe massage was sent. I'm using a WEG PLC410 and a WEG PLC500, and this error occurred in both of them (including in CODESYS Control Win x64). The application sends to the system a message JSON with the float payload Ex. {"data" : 0.8500}, but this happens with a INT, or BOL as well.

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hallo, I have a strange problem with the recipe manager. ISSUE: When using RecipeManCommands not all values are loaded correctly. Saving a recipe with CreateRecipe(), ReadAndSaveRecipe() or ReadAndSaveRecipeAs() works without any problems. BUT: LoadRecipe(), WriteRecipe() or LoadFromAndWriteRecipe() do not load the data correctly. It is Interesting that we have a different error pattern with LoadRecipe() than with WriteRecipe() or LoadFromAndWriteRecipe(). LoadRecipe() does not load all data and WriteRecipe() or LoadFromAndWriteRecipe() overwrites some data or assigns it incorrectly. And it is also strange that LoadRecipe() writes the values to the PLC. Normally it doesn’t do it. It makes no difference whether the memory type is textual or binary. I have an object consisting of STRUCTs which is inserted in the recipe definition. Environment: Codesys V3.5 SP19 Patch 4 (64Bit), Recipe Management 4.2.0.0 *Add a project (reduced to the problem)
