Post by joep on Creating Custom Kinematics ^{CODESYS Forge talk (Post)}
Hi John, Coincidentally I also tried creating a custom kinematics model for a parallel delta2 like the picture I added. bipod_rotary doesn't seem to do the job. Have you accomplished a working model? I'm stuck on error: "smc_cp_invalid_path_elem" while im certain my math is correct since we made it work using single axis movements. Maybe we could help each other Best regards, Joep

Ok, this is a test programme with ADS1115. It is currently configured for the TCA9548 muxboard. If you want to run the ADS1115 single, then change the settings to the default values: ‘Is Multiplex:’ False ‘Stage mux channel numbers:’ [0,0,0,0,0,0,0,0,0] It is also important that the libraries are installed correctly here. But should be in this project

Post by imdatatas on Problem with edge gateway config mode ^{CODESYS Forge talk (Post)}
I encountered the same problem. (Windows10 x64 single language OS). As @eschwellinger mentioned, I uninstalled the latest EdgeGateway version and installed version 3.5.20.0. Now, when I right-click and select "Allow Edge Gateway...", Config mode is activated without any error or warning window and I do not need to manually type [CmpEdgeGateway] for EdgeGateway version 3.5.20.0.

Enabling Anonymous Login 1. Navigate to 'Device' > 'Communication Settings' > 'Device'. 2. Next, click on 'Change Runtime Security Policy'. 3. In the new window, find and check the box for 'Allow anonymous login'. After completing these steps, you should be able to communicate with the OPC UA server.

Try changing the port mode to digital input for each port you want to have 2 inputs in the connection settings for the device. I've successfully used ports for inputs on an AL1920 this way, I think the procedure should be the same for an AL1332.

Good morning dear codesys users. I'm using 3.5.20.40 and I get this warning C0195 when I assign an initial value to xyz. However, if I do it on a single byte (abc), it doesn't display any warning. Why? VAR_GLOBAL abc : BYTE := 100 ; xyz : ARRAY [1..10] OF BYTE := [10(100)] ; END_VAR

So none of the images from the 64bit archive work with any Codesys Control versions? I have tried the last Pi OS with every Codesys Control version and they don't work. I was wondering if there's any stable combination of versions.

Hey, ist es nicht möglich die WagoApp Biblitoheken in zusammenhang mit dem Codesys Control for Win zu nutzen? Wenn ich so eine Bibliothek im Projekt habe, lässt sich das Programm nicht auf das Device Control for Win nicht laden. Entferne ich die Bibliotheke geht es ohne Probleme. Hat damit schon jemand Erfahrung gemacht? Viele Grüße!

Post by superjojo2002 on Licensing info not available. ^{CODESYS Forge talk (Post)}
I recognized that I have to start the two services "/etc/init.d/codemeter" and "/etc/init.d/codemeter-webadmin" in the docker container as well. If I do so, then the command "cmu -x" returns root@sensoredge-field-netfield-produktmanagment:/# cmu -x cmu - CodeMeter Universal Support Tool. Version 7.60c of 2023-Aug-09 (Build 5625) for Linux/ARMHF 64-Bit Copyright (C) 2007-2023 by WIBU-SYSTEMS AG. All rights reserved. So this time there is no indication any more that "Codemeter is not running". But still we are getting the error when using the license manager in CODESYS development system.

Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge talk (Post)}
Good morning @eschwellinger, After some research I found out that the problem is the preinstalled CodeMeter on Raspberry Pi. As I mentioned the CodeMeter was installed on the Raspberry because I use a license from other vendor that needs the CodeMeter to be installed. The problem is that when I uninstall the CodeMeter from Raspberry I am able to detect the dongle from CODESYS and everything works as it should be but now the other product can not detect its own license. When I reinstall the CodeMeter I am back to the initial problem. Is there a way to overcome this conflict through CODESYS?

Post by reinier-geers on License problem gateway ^{CODESYS Forge talk (Post)}
16.4 Epis What has it to do with the manufacture? It just a licence more not. So basicly the idee of codesys sucks. 3s acts like its posible to add a license. And then it depence on the manufacturer. Why ?? Its a computer !! has nothing to do with the manufacturer. Most dont what a basic licence because they have to pay for that. 3s is the problem not the manufacture of the hardware. Its like the licence of the raspberry pi. HMI is not working. Sorry you get a refund. Why suggest that its possible wen its not !!. It cost me a lot of time. Who pays my time. Why do i have to pay for somting thats not working.

Post by arundara on Variable Sync Issue In Soft Plc Redundancy ^{CODESYS Forge talk (Post)}
Hello, I was trying to create a redundancy POC for our application where we read data from few modbus tcp devices. As there is a limitaion that modbus tcp device support only for single master device, we wanted to test how the variable sync happens in redundancy mode. For that i have used the redundancy sample code added a variable "b" under a condition. What i observed was while active controller is running, if passive controller is powerup, passive controller is able to sync all the data configured for redundacny. But after that the variable data which resided under a condition is not synching from active to passive controller. I have attached the image where i have highlighter the variable. Can some help me to understand how redundacny work in codesys soft plc and if there is a solution to sync variable which are under condition, please explain the same or suggestion to achieve the same. Hardware - Raspberry Pi (2 qty) Redundancy licence used - yes in both controllers. Codesys runtime - 4.9.0.0 Codesys software version - V3.5 SP19 if i have posted this question in wrong section, please do let me know in whcih section i have to post this question.

Post by timvh on Unable to Connect to Modbus RTU Device ^{CODESYS Forge talk (Post)}
If your Control Win is the Modbus "Master" then your configuration should be something like: Modbus_COM (Serial port) - Modbus Master (this is the Control Win SoftPLC actively setting up the communication) - Modbus Slave (this is then your WAGO 750-315) You need to add channels to the Modbus Slave configuration to inform the master which variables to read/write from the Wago module. The way you configured it now, the Control Win is also a slave. PS, don't forget to put the PLC (Control Win) in Run.

Post by flappyman on licenses question ^{CODESYS Forge talk (Post)}
I hope this tread will be able to help me. I got your new licenses and it was working perfectly fine. Unfortunately, my PLC got severely damaged and it can not run anymore. Is it possible to somehow release the license so I could use it again. I have all information for the device and can provide it.

Hello to all. I am testing the Codesys KNX package using a raspberry pi to determine if it fits my needs. Does anyone know the limitations of the package when you use it without a license? I searched for it myself but couldn't find any information on the matter. Thank you all for your help.

Post by atone on Change IO-Link Device Interface connected to a Profinet-Slave at Runtime ^{CODESYS Forge talk (Post)}
OK, I figured out that I can simply define all the sensors as 16 bytes IN/OUT, even if they are not all used. EDIT: The negative effect is that each bit is taken into account as an I/O for the license, even if not used.
