A program editor creates a program-edit screen for a control system based on element data for representing circuit elements and operators and their attribute values. Here, the circuit elements and operators are components of sequential programs which constitute functions of the control system. The program editor which edits the element data on the created program-edit screen judges whether the data for representing the circuit elements and the operators is protected-function data or non-protected-function data and displays assembly sets of programs for implementing predetermined functions constituted by circuit elements and operators to which accesses are authenticated on the program-edit screen in a display mode different from those of the other assembly sets.
