Scan monitoring function
(Watchdog timer setting)
(Watchdog timer setting)
Detects an error in the hardware and program of the CPU module by
monitoring the scan time.
monitoring the scan time.
Clock function
This function is used for the time management in the function which
the system operates such as the date of the error history.

Online change
Changing ladder blocks
while online
while online
Writes the part of a program edited on the ladder editor using the
engineering tool to the CPU module in units of ladder blocks. Edited
contents spanning multiple portions can be written to the CPU
module at once.

Interrupt function
Multiple interrupt function
When an interrupt occurs while an interrupt program triggered by
another cause is running, stops the program if its priority is lower
than that of the new interrupt, and runs the higher-priority program
whenever its execution condition is satisfied.

than that of the new interrupt, and runs the higher-priority program
whenever its execution condition is satisfied.
PID control function
Performs PID control by the PID control instruction.
Constant scan
Keeps the scan time constant and executes program repeatedly.
Remote operation
Remote RUN/STOP
Changes the CPU module status to the RUN/STOP/PAUSE status
externally while the RUN/STOP/RESET switch of the CPU module is
in RUN status.

RAS function
Self-diagnostics function
Self-diagnoses the CPU module to see whether an error exist or not.
Error clear
Batch-clears all the continuation errors being detected.
Security function
Protects resources stored in PCs and resources in the units in the
system of the FX5 from illegal access by a third party such as theft,
alteration, accidental operation and unauthorized execution.
