Summary of parameters for CPU 410
Default values
All parameters are set to factory defaults. These defaults are suitable for a wide range of
standard applications and can be used to operate the CPU 410 directly without having to
make any additional settings.
You can define the defaults using the "Configuring Hardware" tool in STEP 7.
The responses and properties of the CPU are defined in parameters. The CPU 410 has a
defined default setting. You can modify this default setting by editing the parameters in the
hardware configuration.
The list below provides an overview of the assignable system properties of the CPUs.
● General properties such as the CPU name
● Watchdog interrupts, e.g., priority, interval duration
● Diagnostics/clock, e.g., time-of-day synchronization
● Security levels
● H parameters, e.g., duration of a test cycle
● Startup, for example, times for completed message from modules and transfer of
parameters to modules
Parameter assignment tool
You can set the individual CPU parameters using "Configuring hardware" in STEP 7. For
additional information, see I/O configuration variants (Page 55).
● The rack number of a CPU 410, 0 or 1
Use the selector switch on the rear panel of the CPU to change the rack number.
● The operating mode of a CPU 410, stand-alone operation or redundant operation
You set the operating mode by configuring a SIMATIC 400 station (stand-alone
operation) or a SIMATIC H station in HW Config.
