PCU-Module-Block = 25-2-49
Location3
For inputs, Location is the Bailey module portion of the Bailey address. For outputs, Location should be 1.
Location4
For inputs, Location is the Bailey block portion of the Bailey address. For station blocks, use the block number of the station block for all parameters of that station. For example, the process variable, setpoint, mode, and control output would all have the same block number however, they would have different Bailey point types (Location. For outputs, Location should be 1.
Location5
Location5 is the Bailey point type. A section named Bailey Point Types later in this chapter describes these point types. For RCMs and device drivers, Location maybe something other than the Bailey point type. See Bailey point type A Location value of 12, 13, or 22 (for CIU04) indicates that a PI point is an output point.

29
The Infi90 Interface does not use the InstrumentTag attribute.
ExDesc
The Infi90 Interface does not use the ExDesc (Extended Descriptor) attribute.
Scan
The Infi90 Interface does not use the Scan attribute. Thus, a user cannot remove a point from the Interface simply by setting its Scan attribute to 0. This behavior is different from that of the vast majority of OSIsoft interfaces.
Shutdown
The Shutdown attribute is 1 (true) by default. The default behavior of the PI Shutdown subsystem is to write the
SHUTDOWN
digital state to all PI points when PI is started. The timestamp that is used for the
SHUTDOWN
events is retrieved from a file that is updated by the Snapshot Subsystem. The timestamp is usually updated every 15 minutes, which means that the timestamp for the
SHUTDOWN
events will be accurate to within 15 minutes in the event of a power failure. For additional information on shutdown events, refer to PI Server manuals.
SHUTDOWN
events can be disabled from being written to PI when PI is restarted by setting the Shutdown attribute to 0 for each point. Alternatively, the default behavior of the PI Shutdown Subsystem can be changed to write
