Purpose
Maintenance Changing the program
and Debug- while it is being executed.
ging
Sampling I/O Memory data.
• Periodic sampling
• Sampling once each
cycle
• Sampling at specified
times
Confirming there are no
errors in instruction execu-
tion.
Recording the time that
power was turned on, the
last time that power was
interrupted, the number of
power interruptions, and
the total PLC ON time.
Replacing the program
without stopping operation.
Reading the time/date
when the user program
was changed.
Reading the time/date
when the parameter area
was changed.
Programming/monitoring
the PLC remotely.
• Programming or monitor-
ing a PLC on the network
through Host Link.
• Programming or monitor-
ing a

• Fatal errors (PLC opera-
tion stops.)
• Not recording
defined alarms and errors
in the error log.
Analyzing time and logic in
execution of an instruction
block.
Recording the time/date of
errors and error details.
Reading recorded error
details.

Use the online editing function from a
Programming Device.
(Several instruction blocks can be
changed with CX-Programmer.)
Data trace at regular intervals
Data trace at the end of each cycle
Data trace each time that TRSM(045)
is executed
Set the PLC Setup to specify the
desired operating mode at start-up.
(Startup Mode)
Read the Auxiliary Area words con-
taining power supply information.
Startup Time: A510 and A511
Power Interruption Time: A512 and
A513
Number of Power Interruptions: A514
Set the PLC Setup so that instruction
errors are treated as fatal errors.
