• Alarm Event Enable

  • When enabled and alarms are enabled on tags, the contents of the triggered alarms will be transmitted via Sparkplug to MQTT Engine and will be inserted into the Ignition Alarm Journal on the server where MQTT Engine is installed.

• Alarm Journal Name - added in release 4.0.30
  • The pre-configured Ignition Alarm Journal name to use for alarm reconciliation

• Filtered Properties
  • A semicolon delimited list of Tag properties to filter/block from being published

  • By default the filtered properties list contains: 

    Code Block

  • Tag properties are only published if different from the default Ignition tag property settings and are only published in BIRTH messages.
• Rebirth Debounce Delay
  • The amount of time, in milliseconds, to delay before processing Rebirth NCMD requests after one has been processed. Default of 5000 milliseconds.
• Reconciliation Window - added in release 4.0.30
  • The amount of time to perform tag/metric reconciliation during birth publish events (in milliseconds)
  • Default is 5000
• Include Sparkplug DataTypes
  • Whether or not to include Sparkplug DataTypes for Metrics in Sparkplug DATA payloads
  • Enabled by default
• Use Cirrus Link Encoder - added in release 4.0.30
  • Whether or not to use the Cirrus Link encoder for Sparkplug payloads. This is not Sparkplug compliant but will properly encode Ignition properties such as Dataset, Document and Array types.
  • Enabled by default

• Name
  • The name of the History Store.
• Enabled
  
  • Checkbox to enable/disable the History Store. Not selected by default.
• Type
  • The type of History Store.
  • Data stored in an In-Memory History Store will not be persisted across a module configuration change, module disable/enable, module restart or power loss. 
  • Data stored in a Disk-Backed History Store will persist across a module configuration change, module disable/enable, module restart or power loss.
• History Max Size
  • Maximum number of megabytes history can use before dropping the data
  • An In-Memory History store will use the Ignition Java Heap memory
• History Max Age
  
  • Maximum number of minutes to store history before dropping the data.
• Flush Quantity
  • The maximum number of tags to publish in a single message upon reestablishing communication.
  • Default is 40,000
• Flush Period
  • The period to wait in milliseconds between acquisition and publishing of the historical data when flushing messages upon re-establishing communication
  • MQTT Transmission queries the history store and builds up a publish, and publishes it, and then delays by the Flush Period.
    The actual message publish frequency is not deterministic as the time to gather the publish from the history store can vary depending on the frequency tag change events occurring, disk speed, CPU availability, etc. For example, if it takes 5s to gather up and publish that payload, the actual message publish frequency will be it will be 5s + the flush period
