Post by manuknecht on Using SMC_MOVTYP.INITPOS without specifying the start position ^{CODESYS Forge talk (Post)}
I am using the object SMC_GEOINFO to generate a trajectory and move a system accordingly using the SMC_INTERPOLATOR function block similar to the sample project CNC10_DynamicPath.project. According to the documentation, the movement type INITPOS does not require a start position in the SMC_GEOINFO object, which is confirmed in the documentation of the SMC_GEOINFO object. When using the movement type INITPOS however, the motion will still start from the starting point defined in the SMC_GEOINFO object (0,0,0 if not specified otherwise). Does someone know how to resolve this or is there an example project that makes use of the INITPOS movement type without specifying the starting point? Thanks in advance!

Post by felipemsgarcia on Generic EtherCAT slave ^{CODESYS Forge talk (Post)}
Hello Edwin, Thank you foryour answer but, I believe I was not very clear in my question, sorry. What I wanted to know is if there is a generic EtherCAT slave object already in CODESYS that I can use for anything, remote IO, Drives, VFD's and so on, as long as I match PDO's. Is there such an object? Thank you again!

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 Visualization using methods and cyclic ST-calls ^{CODESYS Forge talk (Post)}
Im looking for a way to implement ST-code into the visualization element without creating a helper POU or method in my device/application tree. Like visualization properties are evaluated at each VISU_TASK cycle I want to be able to create own ST code which interacts with the visualization interface variables. To be more specific I want to have a property which executes user defined ST-code at each VISU_TASK cycle exactly like its already possible for Input Configuration on various mouse and dialog events. Also a property for initialization (so only executed once) and a timed property would be nice. With the situation right now I'll have to create a POU function which handles the ST-code and misuse a property, like the text variable, to execute this POU function at each VISU_TASK cycle. Or does it exist and I don't know it?

Das ist normal. Nicht alle Properties gehören der Cyclegroup Entweder du führst manuell die Methode Read aus oder änderst die Gruppe für das Property explizit.

That time it was not answered. But yes, it is possible. Search for "Relative movement" properties of the rectangle element. Might need to enable advanced features in the property browser. https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_elem_rectangle.html

Post by garrian on How to sort JSON object in codesys ^{CODESYS Forge talk (Post)}
Hi there, I'm testing out MQTT from my Wago PLC using JSON object. I have managed to publish this {"Temperature":15.6,"Setpoint":38.0} to my broker. Now I', trying to subscribe to the same message. The result is this: '{"Temperature":15.6,"Setpoint":38.0}95}ê$10šå$04$Nå$08²Ÿå$0B` á$08@šå' First, why do I see 95}ê$10šå$04$Nå$08²Ÿå$0B` á$08@šå' at the end of the message? Second, how Can i sort out this data to use it in my program? I followed a youtube tutorial which gave me the attached result, which works. But I need some other smart way of doing this when the object gets even more data in it. Any help is very appreciated :)

Post by jonasz on Discontinuity of A/B/C axis movement. ^{CODESYS Forge talk (Post)}
Hi, My problem was related to the behavior of the modulo axis, but maybe you will find something useful from what I write. The solution lies in path processing. Codesys offers a G-code analysis tool. Insert a CNC object into the project. The CNC settings object will be added automatically. By inserting appropriate processing modules into the CNC settings object and parameterizing them, you can test the behavior of the axis. When the effect is satisfactory, remember to add the module from CNC settings in the correct order in the processing path. Each CNC machine case is different. You need to spend some time to get your design tailored like an Armani suit. Good luck.

Post by timvh on How to implement an interface (IElement)? ^{CODESYS Forge talk (Post)}
See: https://forge.codesys.com/prj/codesys-example/element-collect/home/Home/ This contains an application "OnlineChangeSafeLinkedListExample". What you should do is create a new interface which has your "Priority" property. Then your FB should extend the base element function block and implement your own interface: E.g. FUNCTION_BLOCK MyElement EXTENDS COL.LinkedListElementBase IMPLEMENTS I_MyInterface Then the __QUERYINTERFACE does the magic to check if your "element" also implements your interface. Something like this: // Compares this element with itfElement. // Returns 0 if the elements are equal, < 0 if the element is less than itfElement, // > 0 if the element is greater than itfElement. // This method will be called from sorted collections (e.g. |COL.SortedList|) to sort the elements. // IMPORTANT: The underlying value to be compared with MUST NOT be changed during the lifecycle of the object. METHOD ElementCompareTo : INT VAR_INPUT (* The element to compare*) itfElement : COL.IElement; END_VAR VAR itfIntElement : I_MyInterface; xResult : BOOL; END_VAR // We use integer iInt1 for sorting. xResult := __QUERYINTERFACE(itfElement, itfIntElement); IF xResult THEN IF iInt1 < itfIntElement.Priority THEN ElementCompareTo := -1; ELSIF iInt1 > itfIntElement.Priority THEN ElementCompareTo := 1; ELSE ElementCompareTo := 0; END_IF ELSE ElementCompareTo := -1; END_IF

Hey, Sorry this isn't super helpful, but i had this problem once and was able to resolve it. I can't recall how I solved it and whether it was a problem with my codesys installation or the project itself. If it is the codesys installation, make sure all your required libraries and plugins are installed and available. compare with a colleagues installation if possible. I vaguely recall saving a copy of my project and deleting things one by one until the error went away...

Post by narius on OPC-UA object instances preexisting in imported xml information model ^{CODESYS Forge talk (Post)}
Hi all, is it possible to use object instances that are not instantiated by codesys itself, e.g. have been defined in UA-Modeler ? When I browse the plc with UA-Expert I see those instances, but I have not seen information in codesys or the web if these are writable in codesys. So far, I am under the impression, that it is not possible, but would like to hear from others. Also, is it correct, that it is not possible to create references inside codesys ? Thanks in advance and kr

Post by drml on How to implement an interface (IElement)? ^{CODESYS Forge talk (Post)}
I'm struggling with the implementation of the IElement interface (in the ElementCollections library), which I will use to create a SortedList. I created a class (FB) "Device" that implements this interface and that has a "Priority" property that I want to use in order to compare the devices in my implementation of the ElementCompareTo method. Unfortunately, the IElement.ElementCompareTo method needs an IElement as an input, which doesn't know about the "Priority" property of "Device". I tried to define the input itfElement as a Device, but then it doesn't want to compile, because the type in the implementation doesn't match the interface.

Hallo zusammen, ich habe Schwierigkeiten manche Properties in der Codesys-Application (3.5.19.2) auszulesen. Die Richtung Codesys->Bacnet funktioniert einwandfrei. Für manche Properties, wie z.B. PresentValue funktioniert auch die Richtung Bacnet->Codesys. Beispiel: GVL_Automationstation.udiWartungszeit_Probe := BACnetBinaryValueObjects.BINARY_VALUE_10.udiTimeDelayNormal; oben gelistete Property ändert sich nie in der Codesys Applikation. Hätte jemand einen Ansatz woran es liegen könnte? Grüße Jozef
