System response for a modified hardware configuration

The system response of the SITOP PSU8600 after modifying the system configuration is
explained in this section.
Modifying the system configuration involves changing, adding or removing individual
components.
Risk of electric shock
Before starting to make changes of any kind to the system configuration, the main switch of
the system must be opened and measures taken to prevent it from being reclosed. If this
instruction is not observed, touching live parts can result in death or serious injury.
NOTICE

SITOP PSU8600 does not check that the wiring is correct.
After making any changes to the system configuration, ensure that the wiring is correct in
order to avoid damage to the system.
Comparison of the system configuration by SITOP PSU8600
When the system starts or a configuration is loaded, the system compares the saved system
data with the actual system configuration:
● Article numbers of the individual components installed
● Serial numbers of the installed individual components
● Positions of the individual components in the system configuration
● Firmware versions of the installed individual components
MANUAL operating mode
In the MANUAL operating mode, when the system starts, SITOP PSU8600 compares the
existing system configuration with the system configuration that existed at the last complete
system start.
For an unchanged system configuration, all outputs are activated with the last operating
status before the shutdown.
REMOTE operating mode
In the REMOTE operating mode, when the system starts, SITOP PSU8600 compares the
existing system configuration with the last hardware configuration loaded from a control
system in the REMOTE operating mode.
For an unchanged system configuration, all outputs are activated with the parameters and
operating states saved in the configuration. If, before the shutdown, the last operating state
of an output was "Manually switched off (LED is lit yellow), "Automatically switch off due to
