Post by hijackpager on RS232 Communication in CODESYS Control RTE V3

Based on your description, this issue is usually caused by differences in runtime configuration rather than the PLC code itself. To fix it, ensure the COM port is not used by another application, verify that CODESYSControl.cfg is correctly configured for the serial port, and confirm baud rate, parity, and port settings match the connected device. Testing the port with a simple loopback can help isolate hardware vs. configuration problems. Also check that the RTE runtime version matches the IDE and that required drivers and libraries are available. If the problem persists, creating a minimal test project and sharing configuration details on the forum can help others diagnose it quickly. Gud Luck! geometry dash

Hello, pls help!!! Is there a more detailed manual (for dummies) for writing your own IO drive device in C? Another question: how can I add diagnostics to the IEC IO Drive device so that a red triangle lights up in the project tree in the event of a malfunction?
