702DX32 and 702DX42
Discrete Value: The Discrete Value is reported through the gateway to a control host that
requires the true discrete state value, rather than the floating point decimal of the Analog Value.
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. Please reference
Figure 9-3 on page 86
for limit contact switches and
Figure 9-4
on page 87
for opposing contact switches.
