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.Field of SearchState of condition or parameter (e.g., on/off)Sequential or selective Of analog controllers Position responsive Supervisory control Specific programming (e.g., relay or ladder logic) Plural controlled systems, mechanisms, or elements Plural controllers Sequence program response Operator control of remotely located element Having particular position determining apparatue (e.g., portable or handheld) Having operator control interface (e.g., control/display console) Having preparation of program | |
