Setting the startup behavior
Sets the startup type after POWER ON
Defines the startup behavior when a module in a slot does not correspond to the config-
ured module. You can set this parameter centrally, on the CPU or for each module.
When you change the setting for a module, the setting made centrally for this module no
longer applies.
• Startup CPU only if compatible: In this setting a module on a configured slot has to be
compatible with the configured module. Compatible means that the module matches
in terms of the number of inputs and outputs and with respect to its electrical and
functional properties.
• Startup CPU even if mismatch: With this setting the CPU starts up regardless of the
type of module plugged in.
Specifies a maximum period (default: 60000 ms) in which the I/O must be ready for op-
eration. The CPU changes to RUN.
If the central and distributed I/O is not ready for operation within the configuration time,
the startup characteristics of the CPU depends on the setting of the "Comparison preset
to actual configuration" parameter.
