These are the new features and known and resolved issues for Predix Edge Applications and Services, version 2.1.0.

New Features

This release contains the following new features:
ARM-based Predix Edge Applications
ARM versions of all protocol adapters and cloud gateway components are now available. These will enable Raspberry Pi devices to run these components, providing an accessible, low cost and developer friendly device platform.
Cloud Gateway Enhancements
A new simplified and unified Cloud Gateway component has been implemented with store and forward data buffering capability to transmit data to both Predix Cloud Event Hub and Predix Cloud Time Series.
New Historian Applications
The following new Historian applications have been added:
  • Historian Web-admin Console – dashboard for Historian Data Archiver.
  • Historian S2S Collector – Data Streamer between Historian servers.

Known Issues

This release has the following known issues:

Raspberry Pi
  • Cloud Gateway on Raspberry Pi is known to fail after running for an extended priod of time, due to insufficient memory on the Raspberry Pi device.
  • When the MQTT protocol adapter on Raspberry Pi loses its connection/signal with the Broker, the adapter will not come back online/establish a connection by itself and will be in a locked state. Should this occur, restart the MQTT protocol adapter container.
Transmitting Frequently Changing Data
  • When using OSI-PI to transmit frequently changing data to the Cloud or to an internal application, Edge Engineering guarantees the OPC-UA protocol adapter will transmit up to 100 tags per second. If you are transmitting data at a rate higher than 100 tags per second for an extended period of time, the stability of the application is not guaranteed.
