}
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.
4.1.3
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
4.1.4
Reaction times
Information on the reaction times of the inputs/outputs can be found in the PSSuniversal
System Description.
4.2
Configuration
It is not necessary to configure ST inputs/outputs in the PSSuniversal Configurator on the
PSS WINPRO system software, but ST modules can be selected and displayed.
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.
