5.8.2 Latching feature
The Rosemount 702 has a latching feature that, when enabled, allows
detection of momentary state changes to be held for a configurable latch
period. The latching feature can be configured to detect either high or low
state changes. By default, the Plunger state (channel 1) is enabled to latch
high state changes for a period of one minute.
The following are some examples to demonstrate how the latching time
works.
Note
Hold time is set to four seconds for illustration in the following examples.
