Module features

4.2.1

Functions

The module routes the periphery supply from the module bus to the base module ter-
}
minals.
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
}
4.2.2

Integrated protection mechanisms

When the PSSu E F PS1(-T) or PSSu E F PS2(-T)(-R) 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
}
