TopView PI with AF Support
AVEVA PI System is a data management infrastructure. At the heart of the PI System is a high-performance historian and asset framework that provide access to both current and historical data.
TopView’s PI and PIAF data sources
Our PI data source uses the PI-SDK to monitor PI tag values and PI tag expressions to detect alarm and abnormal events.
Our PIAF data source monitors both PI tag and AF element attribute data. It also supports expressions involving AF element attributes.
TopView for AVEVA PI System includes both PI and AF data sources so you can choose the one that is right for you. Once the PI data values are retrieved by TopView, all other TopView features work the same.
Overview of the TopView PIAF data source
- Efficient and configurable AF attribute and PI tag data monitoring through data pipes, point lists, or polled retrieval
- Monitoring of AF Expression results through a new AFEXP operation. Expressions can contain both PI tags and element attributes.
- Asset/element-based placeholders for asset-relative message content
- %elementpath%: returns full element path for current attribute
- <%attvalue||attname%> returns the value of attribute “attname” for the same element as the current attribute
- <%attvalue||attname||formatstring%> returns the value of attribute “attname” for the same element as the current attribute and formatted according to the passed string
- Data pipe activity monitoring (new events)
- Admin Tools: displays data pipe activity on Performance screen
- piaf_dp_count: status tag and performance counter contains the number of arriving events since last update
TopView PIAF requires the AF-SDK v 2.8.6.7801 (PI AF Client 2016-R2-SP1) or later
