Methods and apparatus to provide version control in a process control system graphical user interface development environment

An apparatus comprising:

• interface circuitry;
• machine-readable instructions;
• and
• at least one processor circuit to be programmed by the machine-readable instructions to:
• cause presentation of a first graphical user interface to enable editing of a second graphical user interface of a process control system, the second graphical user interface based on information stored in a database;
• access a user instruction to modify the second graphical user interface from a first version to a second version;
• access user commit information associated with the second version;
• export the second version of the second graphical user interface from the database to a local file repository;
• synchronize the second version from the local file repository to a remote repository, the synchronization to include the user commit information;
• identify a difference between a first file of the second version of the second graphical user interface and a second file of a third version of the second graphical user interface;
• and
• cause display of a textual representation of the difference within the first graphical user interface.

A method comprising:

• causing, by at least one processor circuit programmed by at least one instruction, presentation of a first graphical user interface to enable editing of a second graphical user interface of a process control system, the second graphical user interface based on information stored in a database;
• accessing, by one or more of the at least one processor circuit, a user instruction to modify the second graphical user interface from a first version to a second version;
• accessing, by one or more of the at least one processor circuit, user commit information associated with the second version;
• exporting, by one or more of the at least one processor circuit, the second version of the second graphical user interface from the database to a local file repository;
• synchronizing the second version from the local file repository to a remote repository, the synchronization to include the user commit information;
• identifying a difference between a first file of the second version of the second graphical user interface and a second file of a third version of the second graphical user interface;
• and
• causing display of a textual representation of the difference within the first graphical user interface.
