Note: A number 1 through 7 comes in place of * depending on the position where the functional module is mounted, such
as OpenNet interface module or analog I/O module. Consequently, operand numbers are automatically allocated to each
functional module in the order of increasing distance from the CPU module, starting with L100, L200, L300, through L700.
Error Data (Status Area) L*12
L*12
b15 b14: unused b13
When an error occurs, the I/O or ERR LED on the L
responding bit in the link register goes on. The status LED goes off when the cause of the error is removed. The error data
bit remains on until the CPU is powered up again or reset.
b15 (initialization error)
This bit goes on when the CPU module fails to acknowledge the completion of initialization for communication with the
L W interface module. When this bit goes on, the I/O LED also goes on.
ON ORKS
b13 (I/O error)
This bit goes on when an error occurs during communication with the L
When this bit goes on, the I/O LED also goes on.
b12 (transaction timeout)
This bit goes on when the CPU module fails to receive an acknowledge reply during communication through the L
W network, with the acknowledge (ACKD) service enabled. When this bit goes on, the ERR LED also goes on. The
ORKS
transaction timeout is enabled only when the ACKD service is selected.
b11 (transmission error)
This bit goes on when a CRC error is detected while receiving incoming data from the L
goes on, the ERR LED also goes on.
