Description
Detects a hardware failure or program error by monitoring
that the END processing is performed within a set scan
time.
Self-diagnoses the CPU module to see whether an error
exist or not.
Displays the FB hierarchy information of the function
block with an error in the "Module Diagnostics" window.
Batch-clears all the continuation errors being detected.
Collects operations executed and errors detected from
the modules, and saves them in the CPU module. The
saved logs can be checked in chronological order.
Replaces the module/unit without stopping the system.
Automatically detects and recovers the data stored in the
program cache memory of the CPU module at the time of
program execution if the data is overwritten due to the
factors such as excessive electrical noise.
Remotely controls the operating status of the CPU
module without switch operation.
Transfers files in the SD memory card to the built-in
memory of the CPU module when the CPU module is
powered off and on or reset.
Checks the status of a running program on the program
editor.
Monitors values in devices and buffer memory using the
engineering tool connected.
Registers devices and labels, and checks the current
values.
Monitors the execution time of each program and the
number of executions using the engineering tool
connected.
Monitors the number of executions of interrupt programs
using the engineering tool connected.
Forcibly turns on/off the external input/output from the
engineering tool.
Changes a device value for the specified step of a
program, using the engineering tool.
Collects data at a specified interval or a desired timing,
and stores them as a file.
Executes programs written in sequential function chart
(SFC).
Performs PID control by using the PID operation
instruction.
A process control program can be easily created by using
process control function blocks.
