IoT Sparkplug EIE

The IoT Sparkplug EIE communicates with an MQTT server through the MQTT Comm EIE. The CygNet IoT Sparkplug EIE subscribes to data that is published to the MQTT server. For more information, see Installing Link. Like most CygNet EIEs, the IoT Sparkplug EIE is a template-driven EIE.

The IoT Sparkplug EIE uses the Sparkplug B version of the specification. It is capable of processing metric items with aliases, historical data, and null values.

This EIE does not support all features of the Sparkplug B specification:

• Complex objects as defined by the Sparkplug template data type are not supported.
• Arrays of records as defined by the DataSet data type are not supported.
• The metric components metadata and is_transient are not used.
• The metric component properties are not used, except for those where name = "units". Units are stored in the DDS transaction; "units" is used in point processing.
