Description
Updates the module's firmware version.
Detects errors in the hardware and program of the CPU module by
monitoring the scan time.
This function is used for the time management in the function which
the system operates such as the date of the event history function,
and data logging function.
Writes the portion edited on the ladder edit window of the
engineering tool to the CPU module in increments of ladders.
Edited contents spanning multiple portions can be written to the
CPU module at once.
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.
Performs PID control by the PID control instruction.
Keeps the scan time constant and executes program repeatedly.
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.
In addition, resets the CPU module externally while the CPU
module is in the STOP status.
Sets the capacity of each area in the device/label memory.
Set to change program capacity.
Sets the capacity of the area (internal buffer) used by the system to
temporarily store the results of data logging and memory dump
processing.
Sets the initial values of devices used in the program directly (not
via the program) to the devices.
Holds the contents of the device and label of the CPU module when
the power is turned off and on.
Makes the SD memory card unavailable without turning off the
power even when the function accessing the SD memory card is
executed.
Transfers the file stored in the SD memory card to the transfer
destination memory judged automatically by the CPU module when
the power is turned off and on, or the CPU module is reset.
Sets the number of execution times of the device/label access
service processing executed by END processing, with parameter.
Collects data at the specified interval or any desired timing, and
stores them as a file on the SD memory card.
Saves the data in the devices of the CPU module at a desired
timing.
Monitors the content of the specified device of the CPU module at a
specified interval or at a desired timing in real time.
Checks if a problem exists with the CPU module.
Batch-clears all the continuation errors being detected.
Collects operations executed and errors detected from the
modules, and saves them in the CPU module, expansion board,
expansion adapter, and intelligent function module. The saved logs
can be checked in chronological order.
