Release Notes for system:inmation 1.74

1.74.5 - February 8, 2021

Improved in 1.74.5

OPC UA A+C Support

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.

OPC UA Source Timestamp Support

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.

Redundant Stream

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

WebStudio Table and EventTable Widgets

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.

Production Tracking and Audit Trail Data Store Queries

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

Retrieval of Audit Trail Data Store records is only supported in MongoDB versions 3.6 and above.

1.74.1 - January 19, 2021

New in 1.74

Pass Through Queries

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.

History Transfer - Generic Time Series Buffer

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.

Read-Only Datasources

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).

MSI Interface

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.

Store and Forward of data from outdated components

Connectors and local cores that are not up-to-date (i.e., not version 1.74) will be unable to forward historical data or events. This affects only the systems where said components are configured for the manual-permissive software update mode. Until the connector (local core) is updated, the data will be stored locally at the outdated component (within the configured storage limits); then the previously stored data will be forwarded normally.

Improved in 1.74

Honeywell PHD integration

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.

PLC Datasources

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

Batch Tracker

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.

DataStudio Unresolved Objects Dialog

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

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

Compatibility of 1.74 with Visual KPI

For system:inmation v1.74, it is recommended to use version of Visual KPI.

system inmation v1.74 remains compatible with older versions of Visual KPI from onwards. However, due to known issues, Visual KPI 5.57 should not be used.
