CONTROL PROGRAM MANAGEMENT SYSTEM AND METHOD FOR CHANGING CONTROL PROGRAM

摘要

A control calculation device causes the contents of a new control program received from an editing device to be displayed on an approval-receiving device. The approval-receiving device receives an input from a manager comprising approval information expressing whether or not a change to the control program is approved. The control-calculation device changes the control program to the new control program when the approval information received from the approval-receiving device is information indicating approval of the new control program.
