Use the individual data entry page to enter tour run data on a per tag basis, and in the tag sequence established during tour configuration. This is the default display for PI Manual Logger Web.

Individual data entry

Individual data entry page layout

On the individual data entry page, the following information and data entry fields are available.

Field	Description
Name and Description	The value for the tag attribute Tag Name is displayed immediately below the navigation buttons. The full group path to which the tag belongs in the tour is displayed under the tag name. If defined, the tag attribute Tag Descriptor is displayed on another line.
Instructions	If defined, operator instructions are displayed.
Value	If defined, the value for the tag attribute UOM (unit of measure) is displayed in parentheses. If the tag is a digital tag or if SYSTEM digital states are associated with the tour configuration, you select to view allowed digital states. If you enter an invalid value for the current tag type, an error message is displayed. You cannot navigate to any other area until you clear or correct the value.
Limits	If defined, limits are displayed under the Value field: HiHi (HiHi limit) Hi (High limit) Lo (Low limit) LoLo (LoLo limit) Delta (Delta limit)
Previous	The previous tag event (value, timestamp, and comment if defined) is displayed after the Previous label. When you expand See historical values, the previous tag event is also displayed at the top of the list.
Timestamp	The timestamp associated with the current tag event is displayed. Depending on tour configuration settings, you can change the timestamp. See Change timestamps.
Comment	A comment is optional unless a limit is configured that requires a comment when violated. If a comment is entered for a tag that has a value, the comment is written to Annotations in the PI system. The comment is also written to a Comment tag if configured for a tag in Tour Configuration (in PI Manual Logger PC).
Historical data	Expand See historical values to view historical tag events. The number of historical tag events displayed for a tag is determined by the cached number set in Number of PI Tag Values to Cache (per tag) field in PI Manual Logger PC Tools > Global Options. Historical tag values are updated directly from Data Archive.
Attributes	Expand See attributes to view attributes associated with the current tag (such as UOM, Zero, Span, Point Type, or Digital Set).

Note: Only one of the historical data or attributes controls can be expanded at a time. Once selected, the control remains expanded as you navigate from one tag to the next, unless you select the control header again to close it.

Harmful characters in Values and Comment fields

All input strings from the Value and Comment fields on the Data Entry page are checked to prevent harmful characters (some of which can harm the browser) from being added to the SQL Server database. The following non-alphanumeric characters are allowed, but other special characters are replaced with blanks:

Character	Description
.	period
-	hyphen
_	underscore
@	at sign
...	ellipsis
(	open parenthesis
)	close parenthesis
