The offline programming device according to claim I, wherein:

• the receiver receives input of a command including the teaching point and an indication of a movement direction of the robot at the teaching point,
• the GUI screen includes a command list area in which a plurality of symbols respectively indicating a plurality of the commands are arranged in a row,
• the first display area is located parallel to the row of the symbols in the command list area, and
• the first display area displays the teaching point at which an error occurs in a manner corresponding to the symbol in the command list area.

An offline programming method, comprising:

• receiving input of a plurality of teaching points;
• determining one or more intermediate points located between adjacent teaching points and creating an operation program for a robot, the operation program including the plurality of teaching points and the intermediate point;
• simulating a movement trajectory of the robot when the operation program is executed;
• and
• displaying a GUI screen representing the movement trajectory,
• wherein:
• the GUI screen includes a first display area showing a time series sequence of the plurality of teaching points and a second display area showing a time series sequence of a plurality of the intermediate points between some of the plurality of teaching points included in the first display area on a larger scale than the first display area, and
• when an error is detected in the movement trajectory, the first display area indicates a section between the teaching points, the section including a point in time when the error occurs, by a first error display method, and the second display area indicates the intermediate point corresponding to the point in time when the error occurs, by a second error display method.
