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, wherein the plurality of operational states comprises a commissioning or maintenance state and a production state, wherein the industrial automation system is configured to not produce a product when in the commissioning or maintenance state and to produce the product when in the production state;
receiving a request to access the industrial automation system from an accessing component configured to 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.

10. A method for controlling access to an industrial automation system, comprising:
-
permitting access to the industrial automation system based upon first criteria when the industrial automation system is in a commissioning or maintenance state, wherein the industrial automation system is configured to not produce a product when in the commissioning or maintenance state; logging accessing components that access the industrial automation system during the commissioning or maintenance state; changing the state of the industrial automation system to a production state, wherein the industrial automation system is configured to produce the product when in the production state; and permitting access to the industrial automation system based upon second criteria during the production state, wherein the second criteria are more restrictive than the first criteria. - View Dependent Claims (11, 12)

13. A system for controlling access to an industrial automation system, comprising:
-
a state determination component configured to determine an operational state of the industrial automation system from a plurality of operating states, wherein the plurality of operational states comprises a commissioning or maintenance state and a production state, wherein the industrial automation system is configured to not produce a product when in the commissioning or maintenance state and to produce the product when in the production state; a receiving component configured to receive 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 automation system; and an access control component configured to determine whether the accessing component is authorized to access the industrial automation system based upon the operational state and to permit or deny access to the industrial automation system based upon the authorization determination. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
