1. A method for controlling access to an industrial automation system, comprising:
- determining an operational state of the industrial automation system from a plurality of operational states;
receiving a request to access the industrial automation system from an accessing component that can interact with the industrial automation system or an industrial automation component of the industrial automation system;
determining whether the accessing component is authorized to access the industrial automation system based upon the operational state; and
permitting or denying access to the industrial automation system based upon the authorization determination.

Abstract
An improved system and method for controlling access of components to industrial automation system resources by reference to the various operational states of the industrial automation system. A central access control system includes a processing circuitry, interface circuitry configured to receive information pertaining to the operational state of an automation system, memory circuitry, and a display and user interface. In operation, access to automation components are either allowed or denied based on the designation of an operational state of an automation system.

11. A method for controlling access to an industrial automation system, comprising:
-
permitting access to the industrial automation system based upon first criteria during a first operational state of the industrial automation system; logging accessing components that access the industrial automation system during the first operational state; changing the state of the industrial automation system to a second operational state; and permitting access to the industrial automation system based upon second criteria during the second operational state, the second criteria being more restrictive than the first criteria. - View Dependent Claims (12, 13)
