A programmable logic controller for use as part of an industrial control system or as part of an automated system and a corresonding method, the controller including an interface to the Internet, and including a web server allowing a remote computer to access web pages maintained by the controller providing information relevant to the control function of the controller such as control sensor readings and, optionally, information about the status of the control system. The web server is implemented as part of the controller in such a way that the controller scan rate (the rate at which the ladder logic for all associated control system devices is repeated) is unaffected by execution of the web server.
