Light error

Was bedeutet E3 ?

A light error indicates a problem that may or may not require the user program to be stopped, depending on the application's design. Examples include issues where Flash memory could not be programmed or an I/O module has failed, but the CPU itself remains operational. The user must decide the appropriate reaction, as ignoring it might lead to impaired functionality of specific I/O or program segments without halting the entire system.

• Non-critical error condition requiring application-specific handling.
• Potential issue with peripheral device communication.
• Minor discrepancy in sensor reading.

1. 1

   Check status of connected I/O modules via their diagnostic LEDs.

2. 2

   Verify communication handshake signals between the controller and peripheral devices.

3. 3

   Inspect parameter settings for user program stop conditions (e.g., P0-01).

4. 4

   Review analog input scaling configuration for relevant channels.
