Integrated protection mechanisms
When the PSSu E F PS1(-T) is used to supply the system, the module supply is buffered
for 20 ms if the supply voltage is interrupted.
The module provides the following diagnostic data:
} Start-up error
} Configuration error
} ST communication error
} Bus termination error
} Output overload
} Temperature error: too warm
} Temperature error: too hot
Reaction times
Information on the reaction times of the outputs can be found in the PSSuniversal System
Description.
Configuration
PSSu assignment in system environment A
It is not necessary to configure ST outputs in the PSSuniversal Configurator on the
PSS WIN-PRO system software. Overload detection and temperature monitoring can be
configured: The entries in the status byte can be deactivated.
The ST process image can be optimised by combining adjacent bits of the same type into
bytes.
Further information on configuration is available in the PSSuniversal Configurator's online
help.
Addresses in the process image
The module occupies 4 consecutive bit addresses for the outputs in the process image of
outputs. If the status byte is activated, it occupies an additional 8 consecutive bit addresses
in the process image of inputs.
