PI PerfMon tags to support Timestamp DataType
There are some performance counters that are Date and Time based.
PI PerfMon tags have to be configured as Float32 or Int32 and at PI AF it has to be converted by using PI Analysis or Formulas. Would be easier to configure, maintenance and to build reports if there is a direct way.

Emerson Ovation Interface: Enable the extraction of the full 32-bit overpacked digital tag as opposed to the now max of 16-bit
Customer would like to extract the full 32-bit overpacked digital tag into an int32 pi point.

Replace pipc.log and PI Message logs with the Event Viewer
PI Connectors already use the Event Viewer to log messages. It is time for PI Interfaces to do the same.

Accept the dd-mmm-yyyy format in the absolute time syntax for history recovery start and end times
The PI Interface for RDBMS currently accepts the format dd-mmm-yy but not the format dd-mmm-yyyy for history recovery start and end times.
The former format lacks the century, so the year is ambiguous. The latter format solves this problem and so should also be accepted as a valid time format.

Unregister interfaces in bulk on ICU
In scenarios where we have to move interface instances to a new machine, we will have to perform some cleanup after of un-registering the interfaces in ICU. This includes removing the bat files and services. It would be nice to perform this task in bulk.

Support redundancy with OPC event tags
Currently, with OPC event tags, if the connection between the interface and PI Data Archive is broken and signups lost, the event tags will stop polling the OPC server for data. I would like to see a level of redundancy added whereby if the OPC-PI Server connection is broken, the event tags will default over to a predefined scan class, or alternatively be advise tags.

Batch Framework Interfaces - [TIME] placeholder should consider whether TS=LCL is configured
Batch Framework Interfaces - [TIME] and [TIMESTAMP] placeholders should consider whether TS=LCL is configured (meaning the interface is processing incoming events as Local Time). Currently, values of these placeholders always show up as GMT timestamps.

New start-up parameter /SYNC_TIME defining a floating-window during which the interface will keep a RDB table in sync with PI data archive
The new RDBMSPI param: /SYNC_TIME=rel_start_time,rel_end_time
for instance /SYNC_TIME=*-6h,*+1h
When set, the interface:
- after each execution of a query, which shall have the same "floating" window in its WHERE clause; for instance:
SELECT time, value, status FROM table1 WHERE time BETWEEN GETDATE()-6 AND GETDATE()+1;
reads events for this tag from the PI data archive (for the interval defined by /SYNC_TIME) and compares timestamps from both sets. The "master" is the set from the rel. database; that is, if in the set taken from PI, there are timestamps, which were not returned from RDB, they are deleted (in PI data…0 votes -
Reference a local .csv file with mappings (TagName-InstrumentTag) to shorten start-up times.
The .csv file with TagName-InstrumentTag mappings will allow start the interface without specifying the PointSource, which will potentially shorten the start-up times against systems with larg point count. Once the interface is running it will update this file with corresponding points, which have been created/updated/deleted while the interface has been running.
Note: This was previously Enhancement 125215.

Support for mathematical operations to be performed on timestamps that are stored as SECONDS_GMT
Time manipulations (adding and subracting) can only be performed on standard datetime formats and not on SECONDS_GMT
Note: This was previously Enhancement 118924.

Create a new function signaling the Beginning of the Stream
Create a new function signaling the Beginning of the Stream. For example, BOS() returns 1 if this is the first line of a stream; otherwise it returns 0.

Support Modbus device failover
Enhance the interface to support redundant Modbus devices with different network cards/IP addresses. The controllers would publish a status update on the active device, and the interface should request data from it accordingly.
