The Point Source is a unique single or multiple character string that
is used to identify the PI point as a point that belongs to a particular
interface. The Point Source for FactoryTalk Historian Live Data
Interface is
FTLD. For additional information, see the /ps
command-line parameter description in "Command-line Parameters
(page 39)".
Typically, device point types do not need to correspond to Historian
point types. For example, integer values from a device can be sent to
floating-point or digital Historian tags. Similarly, a floating-point
value from the device can be sent to integer or digital Historian tags,
although the values will be truncated.
The following point types are supported on PI 3 Servers:
• float16
• float32
• float 64
• int16
• int32
• digital
• string
NOTE
For more information on the individual point types, refer to the
FT Historian SE Server Reference Guide, available in the Common
Files > Rockwell > Help folder in your Program Files
directory.
Location1 indicates to which copy of the interface the point belongs.
The value of this attribute must match the
/id startup parameter.
The default value for the FTLD Local Interface is 1.
