Function description
}
The module routes the periphery supply from the module bus to the base module termi-
nals.
}
The periphery supply is available at the outputs.
The module provides advanced diagnostic data, which is also available in a status byte in
the ST-PII (not in system environment B):
}
Output overload/short circuit
}
Excess module temperature
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
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.
Further information on configuration is available in the PSSuniversal Configurator's online
help.
Addresses in the process image
The module occupies 8 consecutive bit addresses for the status byte in the ST-PII, if the
status byte is configured.
