| 摘要 | 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. | ||

| 主权项 | 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. | ||
