4.1 Module features
4.1.1 Function description
Module supply
} The module supply provides the module with voltage.
Signals at the output
} “0” signal (0 V) at the output:
} Output is high impedance
– No current to the load
} “1” signal (+24 V) at the output:
} Output is low impedance
– Current is supplied to the load
Periphery supply
} The Periphery Supply is not provided via the module bus, but it has to be fed via the
connectors.
} The periphery supply is used to supply the outputs.
Outputs
} The head module sets the output status via the module bus.
4.1.2 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:
} Start­up error
} Configuration error
} ST communication error
} Bus termination error
} Temperature error
4.1.3 Reaction times
Information on the reaction times of the outputs can be found in the PSSuniversal System
Description.
4.2 Configuration
4.2.1 PSSu assignment in system environment A
It is not necessary to configure ST outputs in the PSSuniversal Configurator on the
PSS WIN­PRO system software, but ST modules can be selected and displayed.
