} Via a fieldbus with the modular device description file
With a modular device description file it is possible to configure all the values.
} Via the USB port of the head module, using the PSSuniversal Configurator
All the values can be configured using the PSSuniversal Assistant. Any configuration
via the USB port will overwrite the configuration made via the fieldbus.
If a module has been configured via the head module's USB port, it is locked and cannot be
overwritten by the fieldbus. This lock can be deactivated again in the PSSuniversal Config­
urator.
The following options exist for configuring the module in system environment B:
} Via the head module's USB port with PAS4000.
4.2.1 Voltage range
You can configure the following voltage ranges per module:
} 0 ... +10 V single­pole, referenced to earth (single­ended)
} 0 ... +10 V dual­pole, differential input
} ­10 V ... +10 V dual­pole, differential input
INFORMATION
The inputs on the module are connected differently for single­pole and dual­
pole operation.
Please refer to the section entitled "Wiring" for details.
4.2.2 Digital filter
A digital filter can suppress spurious frequencies in the input signals.
} FIR filters specifically suppress certain spurious frequencies (notch mode). In this way,
for example, the residual ripple from the power supply can be filtered out of the input
signal.
} IIR filters suppress all frequencies above a cutoff frequency (low pass mode). This
means that short­term fluctuations can be filtered out of the input signal.
You can select one of the following filters per module:
} 2nd order FIR filter
} IIR filter, cutoff frequency 1 kHz
} IIR filter, cutoff frequency 100 Hz
} IIR filter, cutoff frequency 50 Hz
} IIR filter, cutoff frequency 20 Hz
} IIR filter, cutoff frequency 10 Hz
} IIR filter, cutoff frequency 5 Hz
} IIR filter, cutoff frequency 1 Hz
} FIR filter, notch frequency 50 Hz
} FIR filter, notch frequency 60 Hz
