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 has the following protection mechanisms:
} Cyclical output tests
} Tests for shorts across the output
} Test pulse signals are always buffered for 20 ms.
The module provides the following diagnostic data:
} Start­up error
} Configuration error
} FS communication error
} Bus termination error
} Temperature error: too warm
} Temperature: too hot
} Output error
} Test pulse error
} Input error
4.1.3 Reaction times
Information on the reaction times of the inputs and outputs can be found in the PSSuniver­
sal System Description.
4.2 Configuration
4.2.1 PSSu assignment in system environment A
4.2.1.1 Dual­pole output
Functions for the FS outputs of a PSSu are defined in the PSSuniversal Configurator on the
PSS WIN­PRO system software:
} Read access through the standard bus system (configured per module):
“R” configuration
} Read/write access through the standard bus system (configured per output):
"&" configuration (local enable principle)
} Optimisation of ST process image by combining adjacent bits of the same type.
“*” configuration
4.2.1.2 Input and test pulse output
Functions for the FS inputs of a PSSu are defined in the PSSuniversal Configurator on the
PSS WIN­PRO system software:
} Read access through the standard bus system (configured per module):
Configuration "R"
} Allocation of a test pulse to an input (configured per input):
