Post by aria13 on Has anyone fed ESP32 sensor data into CODESYS (via MQTT/Modbus)? ^{CODESYS Forge talk (Post)}
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 MQTT brokers and Raspberry Pi projects that bridge MQTT→Modbus, so I’m mainly curious about real-world issues: reliability, message latency, and simple patterns you’d recommend for safe PLC integration. Any tips, examples, or gotchas from folks who’ve done this?

Post by akos on Soft motion kinematic zones ^{CODESYS Forge talk (Post)}
Hello Everyone, Is there any solution to define safety/forbidden zones in the coordinate system of the kinematics? Its not enough, to define only limits in my servo axes! I need zones in 3D! :) Thanks for the help!

Post by drml on Array to String ^{CODESYS Forge talk (Post)}
If a size is not specified, CODESYS allocates 80 characters by default for a string. After 7 seconds, does your Json_string contain all of your 20000 key/values? Or is the result truncated to 80 characters?

I am using the Innomaker USB2CAN-C device to communicate via CAN in the Windows version of CODESYS, but I am encountering error code 27E2, which indicates that the driver is not found. Could you please advise on how to proceed with the CODESYS settings?

I also had this problem connected CODESYS to UAExpert for the first time. In the device, I need to allow anonyomous log in. Follow steps 14 - 17 of the following tutorial: https://docs.factoryio.com/tutorials/codesys/setting-up/codesys-opc-ua-sp17/#creating-the-project

Hello mos89p, I had the same problem. There is a lot of threads about this, but not one up to date. Your solution worked and I was finally able to use my software again. Thank you!
