v2.2.0 (03.08.2022)

Collector supports join operations on Influx1Measurement and MQTTPublishTopicObject.

Features

• Configured multiple upstreams in Influx1Measurement and MQTTPublishTopicObject are valid
• Join operates by combining the timestamps on a best-effort basis

Bugfixes

• Internal library upgrades
• Prevent Data Collector hanging during shutdown in rare cases

• Linear transformation was not applied in MQTTPublishTopicObject

v2.1.0 (14.06.2022)

Introduction of OPC UA BulkRead input symbol and MQTT connection and two MQTT output symbols that write data points in json format to the broker.

Features

• OPC UA BulkRead symbol
  • OPC UA Server uses trigger mechanism to identify new data point
  • Parallel read of multiple OPC UA nodes into a structure
  • Optional handshake with OPC UA server: collector has read the new datapoint(s), collector has written the new datapoint(s) to the output (Influx and MQTT supported)
• MQTT for writing data points to the MQTT broker
  • Data points are sent using JSON
  • Configuration of MQTT Topics
  • Data points can be sent plainly (MQTTPublishTopicPlain) or as json object including timestamp, status, value and other metadata (MQTTPublishTopicObject)

Bugfixes

• Fixed file structure issues with docker image

v2.0.1 (20.09.2021)

Features

Bugfixes

• Fixed sampling interval issues in OPCUASubscription
• Bumped dependent libraries
• Fixed links information displayed in Collector-App

v2.0.0 (24.06.2021)

• Initial release of version 2.0.
