Fieldbus Mode
Figure 12 shows the bus health indicator boundaries. The
high level voltage of a bus must be b3.0 V (MIN)
and +15.0 V (MAX). Depending on the measurement
result, the displayed indicator will be:
Result is between 4.2 and 13.8V. (10 % of
f
12 V = 1.2 V)
Result is between 3 V and 4.2 V, or between
d
13.8 V and 15 V.
Result is <3 V or >15 V.
