Table 9-2. State Table for Reported Values
Note
Changing logic option from direct to inverted has the effect of changing “Open Switch” to “Closed
Switch” on the table above.
Variable reporting, limit contact or opposing contact logic
If the Rosemount 702 Transmitter has two inputs and is set for limit contact or opposing contact logic,
there is a different list of reported values.
Table 9-3 describes the values that are reported as a function of
the Reported Value setting, and the four possible discrete states of True, False, Fault and Travel.
Reference
Figure 9-3 on page 81 for limit contact switches and Figure 9-4 on page 82 for opposing
contact switches.
