Error Information Clear - Mitsubishi Electric MELSEC iQ-R Series User Manual

Error information clear

This section explains the factors causing the ERR LED to be turned ON and the error code initialization (clear) for C24.
Factors causing ERR LED to turn ON
When any of the following errors occurs, its error code is stored in the buffer memory corresponding to the interface (CH)
where the error occurred, and the ERR LED turns ON.
Error factor
Parameter setting error
Mode switching error
On-demand execution error
Data transmission error
Data reception error
Modern function error
MC protocol send error
Monitoring device error
Predefined protocol function
error
Factors causing ERR LED to flash
When any parameter error was detected, the ERR LED flashes, and the buffer memory address which is set out of the range
of the parameter setting value is stored in the error address storage area (Un\G20224 to 20231).
Turning OFF the ERR LED and initializing the error codes
Turn 'Error initialization request' (YE) ON to turn the ERR LED OFF and initialize the error code.
• The buffer memory, which is a factor in turning the LED ON, is initialized.
• The protocol execution logs are not initialized.
