Wizards / alarm limit optimization in the segment transducer block
Wizards are software functions executed inside the F809F itself.
The segment transducer block contains two methods:
•
The Alarm Optimization Wizard optimizes the alarm limits.
•
The "Reset Retransmissions Count" resets the "Total retransmissions
on segment" parameter to Zero. Resetting this value does not reset the
retransmissions of the devices. A reset of both the segment retransmission
counter as well as all device retransmissions can be performed through the
wizard 'Reset retransmit counters' in the System Transducer Block (see
section 5.4.3).
Select 'Configure/Setup' for the segment 1..8 transducer block node.
In the application area, scroll to the bottom to find the 'Alarm Limits Optimization'
wizard, and slightly above it the 'Reset Retransmissions Count' wizard executable via
buttons.
• Wizard 'Alarm Limits Optimization' (for signal amplitude and noise)
The wizard 'Alarm Limits Optimization' in the segment transducer block will
adjust the following PreAlert limits (Alert limits are not modified by the wizard):
•
low- and high-limits of the fieldbus segment power supply
•
high limit for the noise levels (there is no low limit)
•
low- and high-limits for device signal amplitudes.
It also allows the user to select whether a removed or added device creates an alarm
or not.
