Abstract
A programming device for programming a programmable state controller. The programming device translates a control task into an automation-unit control program to be executed by the programmable state controller. The programming device simplifies the programming of a programmable state controller by using a structured text with several sub-structures to formulate the control task.
Claims4
A programming device for programming a programmable state controller, the programming device comprising:
- a memory for storing a structured text representing a control task, the structured text including a plurality of substructures, each substructure including:
- a first keyword followed by a first character string designating an instantaneous state,
- a second keyword arranged after the first character string and followed by a second character string designating an input vector,
- a third keyword arranged after the second character string and followed by a third character string designating a subsequent state,
- a fourth keyword arranged after the third character string and followed by a fourth character string designating an output vector;
- a display for displaying the structured text;
- means for generating a control table that is executable by the programmable state controller, the control table including:
- an instantaneous state generated in accordance with the first keyword and the first character string,
- an input vector assignment generated in accordance with the second keyword and the second character string,
- a subsequent state generated in accordance with the third keyword and the third character string, and
- a control data vector assignment generated in accordance with the fourth keyword and the fourth character string.
