Redundant alias management

A system comprising one or more processors and memory storing instructions that, in response to execution by the one or more processors, cause the one or more processors to:

• identify an alias registered to multiple nodes of a process automation facility, each node comprising a sensor or actuator;
• using the alias, concurrently subscribe to first and second nodes of the multiple nodes;
• while concurrently subscribed to both the first and second nodes, and while a first criterion is satisfied:
• exchange data with the first and second nodes,
• based on the data exchanged with the first node, contribute to a process control loop of the process automation facility, and
• disregard data received from the second node;
• and
• upon determining that the first criterion is no longer satisfied or that a second criterion is satisfied:
• exchange data with at least the second node, and
• based on the data exchanged with the second node, contribute to the same process control loop or a different process control loop of the process automation facility.

At least one non-transitory computer-readable medium comprising instructions that, in response to execution of the instructions by one or more processors, cause the one or more processors to:

• identify an alias registered to multiple nodes of a process automation facility, each node comprising a sensor or actuator;
• using the alias, concurrently subscribe to first and second nodes of the multiple nodes;
• while concurrently subscribed to both the first and second nodes, and while a first criterion is satisfied:
• exchange data with the first and second nodes,
• based on the data exchanged with the first node, contribute to a process control loop of the process automation facility, and
• disregard data received from the second node;
• and
• upon determining that the first criterion is no longer satisfied or that a second criterion is satisfied:
• exchange data with at least the second node, and
• based on the data exchanged with the second node, contribute to the same process control loop or a different process control loop of the process automation facility.
