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 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 stribor on Passing properties as VAR_IN_OUT variables. ^{CODESYS Forge talk (Post)}
I am designing a custom slider object and i ran into a problem when i want to use properties with it. I can update the basic variables if i have a slider variable defined as VAR_IN_OUT, but it does not work with properties. How can i achieve same functionality that some basic objects have (for example basic Slider that comes withing the codesys libraries) such that i can pass both variables and properties to it and they can be modified within the object? I am using Codesys V3.5 SP20 Patch 5.

I can install the runtime and download the software completly but after a few seconds the connection disconnects with the message no connection to device. Please scan network again. And the object reference was not set to an object instance. See screenshot. Can somebody help me with that? Thanks

Post by simotion on Inheritance of axis ^{CODESYS Forge talk (Post)}
I have developped a function block 'Axis' the inherits from 'AXIS_REF_SM3' -> FUNCTION_BLOCK Axis EXTENDS AXIS_REF_SM3 In my global variable list I define a variable MasterDrive of type Axis and assign Axis1. Axis1 is a virtual drive (AXIS_REF_VIRTUAL_SM3). This type should inherit from AXIS_REF_VIRTUAL. VAR_GLOBAL MasterDrive : Axis := Axis1; However I get the error 'Cannot convert type'. What is the way to obtain what I want : function block inheriting AXIS_REF_SM3 and initialising this function block with a Softmotion virtual or real axis?

Hello, For my delta robot i wil use the MC_MoveCirvularAbslolute function. Every time that i set the execute of this function has my Axis group a error. Thats is: The dynamic limits for the movement are invalid. What can i do that this error go away? I saw a view funcitons with limit dymanics but i don't now how they work. If i use the function MC_MoveLinearAbsolute than i have no error. Does anyone know how i fix this?

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 micik on CAA File, how to check whether file exists or not ^{CODESYS Forge talk (Post)}
Hello, what would be the most efficient way to check whether the file exists or not. I don't want to use file.Open function, it seems like rather inefficiet operaton. I considered GetAttribute function, but this function doesn't accept filename (with path) as an input. Basically I need to check first time when program is loaded to the runtime i.e. when application is started for the first time, whether a file exists on the specific location or not.

Hi We have picked up an issue OSCAT_BASIC.Scale_r function call not working in the old lad and FBD version 4.60. Gives no output on the function call. When we convert this to LAD2 it works. As can be see by the two screenshot in normal LD not working in LAD2 it works. Please confirm if this is an issue with Oscat or with LAD in 3.5.21sp3, is there an workaround. Regards Shaun

here is formula for scale function you can impliment your own scale function Output=OutMin+(Input−InMin)×(InMax−InMin)(OutMax−OutMin) FUNCTION_BLOCK FB_Scale VAR_INPUT xIn : REAL; // Input value (e.g., raw sensor) xInMin : REAL; // Input range minimum xInMax : REAL; // Input range maximum xOutMin : REAL; // Output range minimum xOutMax : REAL; // Output range maximum END_VAR VAR_OUTPUT xOut : REAL; // Scaled output END_VAR VAR xGain : REAL; xOffset : REAL; END_VAR // Implementation xGain := (xOutMax - xOutMin) / (xInMax - xInMin); xOffset := xOutMin - xGain * xInMin; xOut := xGain * xIn + xOffset;
