SECURITY, SAFETY, AND REDUNDANCY EMPLOYING CONTROLLER ENGINE INSTANCES

摘要

The claimed subject matter provides a system and/or method that facilitates employing safety within an industrial environment. An enhancing component can implement at least one of a security level, authentication, authorization, or an access right to a validated action to at least one of the controller or the controller engine instance. The enhancing component can further separate two or more entities within the industrial environment, the first entity related to process control and the second entity related to process safety. Additionally, the enhancing component can employ at least one of a backup controller or a backup controller engine instance in the event of at least one of a software error or a hardware error within the industrial environment.

主权项

1. An industrial controller, comprising:
a processor; and a memory communicatively coupled to the processor, the memory having stored therein computer-executable instructions configured to implement the system, comprising:
an enhancing component configured to generate a first controller engine instance having a first security level for control of an industrial process and a second controller engine instance having a second security level for control of a safety device; anda redundancy component configured to generate one or more backup controller engine instances for at least one of the first controller engine instance or the second controller engine instance, wherein the redundancy component determines a quantity of the one or more backup controller engine instances based on ratio data maintained in a data store specifying a ratio of backup controller engine instances to primary controller engine instances.
