Response when expected and actual configurations do not match
The expected configuration is represented by the configuration loaded into the CPU. The
actual configuration is the actual configuration of the automation system. If the expected
configuration and actual configuration deviate from one another, then the CPU's behavior is
specified by the setting of the hardware compatibility. For additional information about the
hardware compatibility, see the section Operating mode transition (Page 99).
Can
c
eling a startup
If errors occur during startup, the startup is canceled and the CPU remains in "STOP" mode.
Under the following conditions, a startup will not be performed or will be canceled:
● If no SIMATIC memory card is inserted or an invalid one is inserted.
● If no hardware configuration has been downloaded.
Parameter assignment of startup behavior
You can assign parameters for the behavior of the CPU in the "Startup" group of the CPU
properties. Additional information on configuring the startup behavior can be found in the
Operating mode transitions (Page 99) section.
8.4.3 "STOP" mode
Function
In the "STOP" operating mode the user program is not executed.
All outputs are disabled or react according to the parameter settings for the respective
module: They provide a substitute value as set in the parameters or retain the last value
output and thus hold the controlled process in a safe operating mode.
