System(s), device(s), and method(s) provide automated configuration of operator interface(s) in an industrial control system, the automated configuration is based at least on control logic that regulates a process and associated equipment in an industrial environment. A terminal that renders control data can acquire the control logic and associate a set of control data structures therein to one or more display objects, which can be retained in a set of libraries stored in the terminal. Based at least on the association, the terminal automatically generates a rendering project that can render an operator interface that conveys control data according to the control logic. A mapping enables association amongst a control data structure and a display object; the mapping can include relationships amongst display objects for numerous domains of industrial control. The operator interface can be refined autonomously or through external data received at the terminal and associated with predetermined event(s).

A programmable controller for sensing the status of input devices and controlling the state of operating devices in accordance with a stored ladder logic control program includes a step sequencer. A memory is provided for storing data regarding each step of the sequence. This data defines the operating device states for each step, and the legitimate transitions from that step to other selected steps in the sequence, along with the input status conditions which trigger a step transition. A processor responds to a ladder logic instruction by comparing the status of the input devices to the stored input status conditions for the current step to detect if a step transition should occur. Upon such a detection the sequencer advances to the step associated with the detected input status condition. Should an illegal transition from one step to another occur, an error message is generated. A step timer is also incorporated to force a transition when the sequencer remains at the same step longer than a defined period of time.
