Release Notes for system:inmation 1.74

Fixed a potential problem with history queries made to unreachable MongoDB servers. Improvements to the error handling for different situations where the MongoDB server is unresponsive or not configured correctly.

Improvements have been made to the Audit Trail Display, fixing issues with empty timestamp fields and the export function. JSON viewer option has also been added to context menu for audit entries. Filter time added to toolbar and Query and Returned time fields added to the display footer.

Fixed regression, introduced in 1.74.9, where history displays would show history of referenced item when referencing object is added to a display.

Issue fixed with OPC Classic events not being delivered to the Server component after restart of the Core.

Issue fixed with cursor error message when using the History Sink to sink data to AspenTech IP21 systems.

Improved handling of workspace changes when DataStudio disconnects from Core. Also, improved field layout and sorting behaviour in the Event View Display and resolved issue when restoring HistoryTrend Display from saved config file.

Optimizations have been made to the performance of data transport to the Generic Time Series Buffer.

Issue fixed where in certain circumstances, the lifetime management of Mongo client when performing BPR MongoDB operations could cause problems.

Support for special characters when reading property values. Increased support for authentication against Windows authorization groups. Fixed issue with default Minimum Connections property value.

Multiple improvements to WebStudio including: Diff Editor improvements, scroll bar on Report Viewer Widget, Filters, column width configuration and support for hierarchical structures on Table Widget, added cursor support and root path configuration for KPI Model in Chart Widget. Other small bug fixes and improved error reporting.

The support for OPC UA A+C has been increased with a brand new storage schema specific to UA alarms accompanied by changes to the Lua API geteventhistory function and changes to the Event View display.

It is now possible to select whether to use source or server timestamps on OPC UA Servers connected to the system with the OpcUaUseSourceTimestamp Property of the OPC UA Datasource object.

An issue with the Redundant Stream object has been fixed that caused it to not work correctly with script events.

Improvements have been made to WebStudio including default column sorting in the Table widget and improved widget refresh functionality. An issue with filtering via timestamps in the EventTable widget has been fixed in this release.

Improvements have been implemented to make the querying mechanism for the Production Tracking and Audit Trail data stores more robust.

Data that resides in external Datasources (for example OPC servers, OSI PI systems, SQL servers) can be queried using the Web API without any requirement for data storage within the system. These queries will be passed through the system components allowing for on demand querying of Datasources connected to remote Connectors.

The new Generic Time Series Buffer extends the Store and Forward sub-system to aid the efficiency of transporting data to the cloud using the history transfer chain. The Generic Time Series Buffer allows data transfer from remote Connectors to cloud locations without needing to write data to MongoDB.

PLC and OPC (UA, DA, HDA and XML) Datasources can operate in Read Only Mode. In this mode, attempts to issue external writes will be denied and logged in system log and audit trail (if configured).

The MSI interface offers the possibility, to process incoming data with a user-defined script. Likewise, outgoing data can also be generated using a user-defined script. This mapping option is called Custom Script.

History Transfer Objects now support the use of the PHD Bridge to read data (HistoryTransporter) and/or write data (HistorySink) efficiently using Honeywell’s native PHD API.

Performance of read operations on S7 PLCs has been significantly improved.

The API to retrieve stored batches from the database has been improved. It is now possible to use MongoDB commands like $elemMatch and to return only BPR-IDs instead of complete records.

The dialog has been improved giving the user a better overview of displays with unresolved objects as well as more control over resolving them.

PI Bridge now targets .NET 4.6.2 (previously .NET 4.5.2) and uses the latest SDKs of both PI (1.4.7.618) and AF (2.10.9.593).
