Sequence program display apparatus

A method of executing, debugging and displaying a sequence program executed by a programmable controller used to control a machine tool, comprising:

• imputing an address of related data stored in said programmable controller is associated with a rung of said sequence program used to control said machine tool;
• storing said input sequence program and said address of said related data;
• controlling an operation of said machine tool by executing said rung of said sequence program in conjunction with said related data stored at said address;
• and
• displaying on a single screen a result of said machine tool executing said rung of said sequence program and executing said related data stored at said address.

A sequence program display apparatus displaying a sequence program controlling a machine tool, said sequence program display apparatus comprising:

• a keyboard to input an address of a related data associated with at least one rung of said sequence program;
• a programmable controller, coupled to the keyboard, controlling an operation of said machine tool by executing said rung of said sequence program in conjunction with said related data stored at said address in said programmable controller;
• and
• a display unit, coupled to the programmable controller, and the keyboard, displaying on a single screen thereof a result of said machine tool executing said rung of said sequence program and executing said related data stored at said address in said programmable controller.

A sequence program display apparatus displaying a sequence program used to control a machine tool, said sequence program display apparatus comprising:

• a keyboard inputting an address at which related data is contained which is associated with a rung of said sequence program;
• a storage unit, coupled to the keyboard, storing said input sequence program and said address of said related data;
• a programmable controller, coupled to the storage unit and to the keyboard, controlling the operation of said machine tool by executing said rung of said sequence program in conjunction with said related data stored at said address;
• and
• a display unit, coupled to the keyboard, the storage unit, and to the programmable controller, displaying on a single screen thereof a result of said machine tool executing said rung of said sequence program and executing said related data stored at said address.
