6.8 Recording the operation contents and self-diagnostics error occurrence contents (operation/error history
function)
6
FUNCTIONS
(b) Self-diagnostics error
The contents of the self-diagnostics error detected by the CPU module are stored.
For details on self-diagnostics errors, refer to the following manual.
QSCPU User’s Manual (Hardware Design · Maintenance and Inspection)
(3) Operation · history capacity
The contents of 3000 operations and errors can be stored in the operation/error
history of the CPU module.
When the total number of operations and errors exceeds 3000, the oldest content is
overwritten with the latest one in order.
Table6.13 Operations stored in the operation/error history
Classification Operation code Operation message Operation description
System
OP001
SYSTEM INITIALIZE OPERATION
MODE
Because the safety CPU operation mode is
not retained correctly, the CPU module
initialized the safety CPU operation mode
in TEST MODE.
OP002
SYSTEM INITIALIZE PROGRAM
MEMORY
Because the program memory contents
are not retained correctly, the CPU module
formatted the program memory.
OP003
SYSTEM INITIALIZE OPE./ERROR
LOG
Because the operation/error history
contents are not retained correctly, the
operation/error history was initialized into 0
incidents.
OP004 SYSTEM INITIALIZE SYSTEM CLOCK
Because the system clock data is not
correct, the CPU module initialized the
system clock data.
OP005 SYSTEM INITIALIZE PLC MEMORY
The CPU module executed the PLC
memory initialization function.
OP006 SYSTEM INITIALIZE ROM WRITE INF.
Because the write to ROM information is
not retained correctly, the CPU module
initialized the ROM information.
