PURPOSE:To improve the efficiency for the development and formation of a program, by calling out and then illustrating a formulated standard circuit form a memory and then giving additions and corrections of data to the standard circuit to form a user program. CONSTITUTION:A standard circuit memory 9 stores a formulated unfinished program in the form of a standard circuit. Then the standard circuit is displayed on the screen of a CRT6 from the memory 9, and the mode key on a keyboard 5 is set in a circuit formation mode to execute a forming routine of a program. Then the number of a certain circuit element in the standard circuit is set by setting a display cursor at its symbol area and then pushing a ten-key. The writing key is pushed to fix the circuit element to which the number is added. Thus the deletions/additions and corrections are given to the standard circuit displayed on the CRT6 in terms of the element number, the change of the circuit element, etc. |
