Synch manager for high availability controller

A method of synchronizing corresponding application tasks executing on an active controller and on a standby controller, the active controller and the standby controller each configurable for use in an electrical substation, the method comprising:

• identifying an application task executing on the active controller and the standby controller capable of synchronization;
• defining, for the application task, one or more synchronization points at which execution of the application task is to be synchronized;
• synchronizing execution of the application task on the active controller and the standby controller at each of the synchronization points;
• determining a first state of execution of the application task executing on the active controller at the synchronization points;
• transmitting the first state from the active controller to the standby controller via a communications channel established therebetween;
• and
• verifying a successful synchronization of the application task on the active controller and the standby controller based on a comparison of the first state with a second state of execution of the application task executing on the standby controller at the synchronization points.
