I know I'm thinking about this wrong -- too many decades of procedural and event-driven programming and only a few months of PLC ST programming...... I've created a visualization with a button that when pushed calls a method. I want the method to take a pressure reading, wait one minute and then take another pressure reading. I'm looking for leaks. I'm using TON for the delay. It seems like what is happening is that the method gets called once and it takes the first reading and starts the TON. But...
Greetings to all, I'm working on a webvisu project on control win V3 x64 runtime, and have purchased 3 licenses for my application. -Codesys Control Standard M -Codesys Visualization L -Codesys Communication M I have them installed on a Codesys usb dongle When I try to download the program, a login error window appears with the message "No valid license found for the webvisualization". The control win v3 communicates with 3 plc, and have enabled communication over codesys V3 communication by adding...

Call 10 FB instances. Connect Motor_1_Fault to the i_xHW_FaultDetected pin of FB 1, Motor_2_Fault to FB 2... By doing this, your FB will be flexible. The programming will be smooth like a perfect Drift Boss, instead of "hitting the wall" because it can't be reused!
I've been playing with the code using the Windows soft master and the ReadNbrSlaves function block seems to work here: https://content.helpme-codesys.com/en/libs/EtherCATStack/4.8.0.0/EtherCATStack/pou-ETCMasterStack/DynamicConfig/fld-DynamicConfig.html
While trying to install CODESYS 3.5.17.30 (64-bit) on my Windows 11 computer, I'm getting the errors below. The first error occurs near the end of the installation. Once you bypass it, the installation returns the second error. Do you have any suggestions for a solution? By the way, I've tried this on several PCs, but I haven't found a solution.
Thank you for your answer. The build > Generate Code start the code of the application but does not modify the compileinfo. I work with .projectarchive to avoid this kind of problem. I would like to have the possibility to modify the compileinfo by myself so I can indicate the losses information.
Hi, What is exactly the difference between using symbol configuration as OPCUA server or using the Codesys object OPCUA server? What are the advantages and disadvantages of using symbol configuration and OPCUA server object. Please let me know
Has anyone tried sending live sensor data from an ESP32 into a CODESYS runtime (for example via MQTT gateway or a Modbus bridge) to trigger PLC logic? I was reading an ESP32 → MQTT tutorial (https://www.theengineeringprojects.com/2021/11/esp32-mqtt.html) that shows how easy it is to publish sensor data from an ESP32, and I’m wondering how practical that is when tying the stream into industrial control software like CODESYS. I’ve also seen Arduino forum threads where people relay sensor streams to...
