This article explains how the MaintainX® Ignition Module works with Ignition Gateway Redundancy to ensure high availability and continuous data streaming.

Redundancy refers to running two Ignition Gateways, a Master Gateway and a Backup Gateway (also called master node and backup node), in a paired configuration so your integration keeps running even if one server fails.

For more information, see the Ignition Redundancy Documentation.

Prerequisites​

This feature requires Ignition master and backup nodes configured with redundancy.

Installation and Configuration​

  • Before you enable redundancy, manually install the MaintainX module on both the Master and Backup Gateways.
warning

If you install the MaintainX module on the Master Gateway first and enable redundancy later, the Master and Backup Gateway pair enter a redundancy error state.

  • After you enable redundancy, any configuration changes on the Master Gateway are mirrored to the Backup Gateway.
warning

Install the .modl file on the Backup Gateway using the same steps described in Set up the Ignition Module before you turn redundancy on. This prevents redundancy errors when the Backup node comes online.

Configuration Restrictions​

  • You cannot modify the MaintainX module settings directly on the Backup Gateway. All changes must be made on the Master Gateway.
note

The only action allowed on the Backup Gateway is enabling or disabling the module. Disabling the module on the Backup Gateway prevents tag values from being sent to MaintainX if the Master Gateway fails.

Normal Operations​

  • The Backup Gateway remains in standby mode until a failover occurs, regardless of the Standby Activity Level (Cold or Warm)
  • During normal operations, only the Master Gateway actively sends new tag values to MaintainX.

Failover Behavior​

  • In the event of a failover, the Backup Gateway takes over seamlessly, ensuring continuous data streaming to MaintainX.
  • The Backup Gateway starts monitoring tags and transmitting any new tag values to MaintainX.

Failback Behavior​

  • When the Master Gateway is back online, it automatically resumes its role, and the Backup Gateway reverts to standby mode.
