PI Interface to the Baily System

SHUTDOWN
events only for PI points that have their Shutdown attribute set to 0. To change the default behavior, edit the
\PI\dat\Shutdown.dat
file, as discussed in PI Server manuals.
Bufserv
It is undesirable to write shutdown events when Bufserv is being used. Bufserv is a utility program that provides the capability to store and forward events to a PI Server, allowing continuous data collection when the Server is down for maintenance, upgrades, backups, and unexpected failures. That is, when PI is shutdown, Bufserv will continue to collect data for the interface, making it undesirable to write
SHUTDOWN
events to the PI points for this interface.
Output Points
SourceTag
The source tag is the PI tag from which the output point gets the value to send to the Bailey Net / Infi90. For example, the source tag can be a performance equation calculation tag or a lab (manual input) tag. When the source tag is not defined for an output point, the interface will get the output value from the output tag snapshot. In this case, the user is responsible for updating the value directly.
Bailey Point Types
Analog data from Bailey control system should be stored in the PI Server as afloat type
(e.g., Float, Float, or Float) point. If the quality of the value is good, the floating point value from the CIU exception report is stored in the PI point. If the passed quality is bad, the digital code for
BAD INPUT
is stored for that tag.

PI Point Configuration
30
If Bailey analog data is configured to be stored as a digital point in the PI Server, the CIU exception value is interpreted as the offset from the digital starting code of the point. Any value out of the range of the point's digital state set is stored as
BAD INPUT
The different types of Bailey points are further described below:
