Abstract
A ladder program device includes circuitry which stores a register value to be used in a ladder program, displays the register value in a register value display area, and receives a selection for one of a first rewrite input and a second rewrite input for the register value displayed in the registered value display area, the circuitry receives the selection by accepting the first rewrite input if a value to modify the register value is entered and accepting the second rewrite input if at least one portion of the register value display area is selected to modify the register value.
Claims20
A ladder program device, comprising:
- circuitry configured to
- store a register value to be used in a ladder program,
- display the register value in a register value display area, and
- receive a selection for one of a first rewrite input and a second rewrite input for the register value displayed in the registered value display area, the circuitry configured to receive the selection by accepting the first rewrite input if a value to modify the register value is entered and accepting the second rewrite input if at least one portion of the register value display area is selected to modify the register value.
A method for monitoring a register value, comprising:
- storing a register value to be used in a ladder program;
- displaying the register value in a register value display area;
- specifying which one of a first rewrite input and a second rewrite input for the register value displayed in the registered value display area is to be selected for the register value;
- receiving a selection for one of the first rewrite input and the second rewrite input the register value by accepting the first rewrite input if a value to modify the register value is entered and accepting the second rewrite input if at least one portion of the register value display area is selected to modify the register value;
- and
- specifying a mode of display for the register when the second rewrite input is selected.
A machine control device, comprising:
- a non-transitory computer readable medium having stored thereon a program that when executed by an external electronic device causes the external electronic device to execute a method of monitoring a register value, comprising storing the register value to be used in a ladder program, displaying the register value in a register value display area, specifying which one of a first rewrite input and a second rewrite input for the register value displayed in the registered value display area is to be selected for the register value, and receiving a selection for one of the first rewrite input and the second rewrite input for the register value by accepting the first rewrite input if a value to modify the register value is entered and accepting the second rewrite input if at least one portion of the register value display area is selected to modify the register value;
- and
- circuitry configured to connect to the external electronic device, determine whether the program is installed on the external electronic device, and transfer the program to the electronic device if the program is not installed on the external electronic device.
