• Block Property Changes
  • Whether or not to block incoming properties from modifying MQTT Engine tag properties. This is false by default so property changes will be applied if not included in the Filtered Property list under 'Advanced'.
• Store Historical Events
  • Whether or not to write historical change events directly to the Historian (if history is enabled on a Tag) instead of updating the live Tag value.
  • Note: Store and Forward does not guarantee all data is stored and forwarded. There are some edge cases that are not currently handled with regard to data loss in the event of connection failures related to MQTT keep alive timeouts. This window of potential missed data can be reduced by decreasing MQTT Transmission and MQTT Engine configurable keep alive timeouts.
• Reordering Timeout
  • Sets the Sparkplug Reordering Timeout in milliseconds.

  • When enabled (greater than zero), MQTT Engine will wait up to the specified number of milliseconds after receiving an out of order message for the expected message to arrive before considering it a failure.

    Note
    If upgrading from a pre 4.0.14 module with a "reorderingTimeout" custom property configured, the upgrade will migrate the value for the custom proprty property to the Reordering Timeout property. The "reoderingTimeout" custom parameter will be deprecated.
