Plugged Impulse Line

Configuration in EDDL

Host systems that support Electronic Device Description Language (EDDL)

may use labels for the PIL configuration parameters that are slightly different

from the Fieldbus parameter names described previously in this section.

Table 6-2 below shows the correspondence between the fieldbus parameter

names used in this document, and the labels used in EDDL hosts, such as

AMS Device Manager.

Viewing the Indication of

a Plugged Impulse Line

When a plugged impulse line is detected, a PlantWeb alert is generated, and

this alert can be seen in AMS Alert Monitor. Also (optionally), using the “Affect

PV Status” parameter, the status of the pressure measurement can be made

to change from “Good” to “Uncertain” when the line plug is detected.

Dependent upon the DCS configuration, the uncertain status of the

measurement may be indicated within the Operator Interface.
