An engineering tool is used for editing data of program components of programmable logic controllers which form a programmable logic controller system which enables a plurality of users to simultaneously edit the program components, and for writing the edited data of the program components to the programmable logic controllers. The engineering tool includes a program component editing method setting unit configured to set the timing at which the data of the program components changed by the editing is transmitted to other engineering tools in which the data of the program components is being edited, for each of the program components. |
