Error Log Structure
550
Each time that an error occurs, the CPU Unit stores error information in the
Error Log Area. The error information includes the error code (stored in
A400), error contents, and time that the error occurred. Up to 20 records can
be stored in the Error Log.
In addition to system-generated errors, the PLC records user-defined
FAL(006) and FALS(007) errors, making it easier to track the operating status
of the system.
A user-defined error is generated when FAL(006) or FALS(007) is executed in
the program. The execution conditions of these instructions constitute the
user-defined error conditions. FAL(006) generates a non-fatal error and
FALS(007) generates a fatal error that stops program execution.
The following table shows the error codes for FAL(006) and FALS(007).
Instruction
FAL(006) #0001 to #01FF (1 to 511 decimal)
FALS(007) #0001 to #01FF (1 to 511 decimal)
When more than 20 errors occur, the oldest error data (in A100 to A104) is
deleted, the newest record is stored in A195 to A199, and the other errors are
shifted by one.
