OVERVIEW
(2) The safety CPU operation mode is equipped for safe system operation
The CPU module is equipped with two safety CPU operation modes. "SAFETY
MODE" for safe system operation and "TEST MODE" for system construction and
maintenance.
These two modes prevent the user's erroneous operations for safe system operation.
(a) SAFETY MODE
SAFETY MODE is a mode for safe system operation. This mode prohibits the
write operation from a programming tool and the device test operation during the
system operation.
(b) TEST MODE
TEST MODE is a mode for maintenance. This mode enables the write operation
from a programming tool and the device test operation to debug or maintain the
sequence program.
For the details of operations available in the SAFETY MODE and TEST MODE, refer
to the following manual.
QSCPU User's Manual (Function Explanation, Program Fundamentals)
(3) Enriched operation history and error history
The CPU module can record a total of 3000 details of the CPU module operation by
the user and errors occurred in the CPU module or CC-Link Safety as operation/error
history data.
Recording the details of the CPU module operation by the user into the operation/
error history clarifies the occurrence order of operations and errors.
Troubleshooting becomes easier by confirming the operation/error history.
The contents recorded in the operation/error history are shown in Table1.2.
