Introduction
As described in section 5.1.7, you can use three methods for configuration:
Manual
Via DCS template
Using Wizards/Methods
The segment transducer blocks allow all parameters to be configured through
wizards/methods. A manual configuration is possible but not necessary.

Manual or via DCS template
Fieldbus Power Supply
Limits for the fieldbus power supply should be according to minimum and maximum
output voltage as listed in the datasheet of the respective FFPS. Default values and
the input value range are as shown in the following table.
Default
Low-low limit, low limit: 18 V
High limit, High-high limit: 32 V
Minimum value
0 V
Maximum value
40 V
Alarm hysteresis (no alarm

1 V
Note that the limit values have to be in rising sequence at all times:
Low-low-limit
≤
low-limit < high-limit
≤
high-high-limit
and high limit must be at least 1 V higher than low limit.
Noise Limits
