METHOD FOR PROVISION OF ACCESS TO CONFIGURATION DATA WITHIN AN INDUSTRIAL AUTOMATION SYSTEM AND WEB SERVER COMPONENT

摘要

To provide access to device configuration data of an IPv4-based automation device within an industrial automation system, upon requesting a web document with device configuration data, a check is made as to whether the request originates from an IPv6 subnetwork or is associated with a web server component from a requesting communication device Target resource identifier with an IPv6 address or with a device name. For a positive verification result, the web document is provided with a reference to the device configuration data that includes an IPv6 address expression or a device name of the particular automation device. In contrast, the reference to the device configuration data in a web document request originating from a requesting communication device from an IPv4 subnet and / or comprising a destination resource identifier having an IPv4 address includes an IPv4 address expression.
