Abstract: An isolation list containing information on a master/slave relation of isolation devices is stored in a history file. A range setting unit sets an isolation range according to a specifying operation with respect to the system diagram of equipment displayed on the screen. A master device registration unit extracts an isolation device present in the set range and registers it as a master device in the isolation list during editing. A slave device search unit successively selects a master device from the isolation list during editing, searches an isolation device which is in a relation of slave device with respect to the selected master device from the history file, and displays a slave device list. A slave device registration unit inserts and places a slave device selected based on the selecting operation of the slave device list after the corresponding master device in the isolation list during editing, thereby completing the list.

A range setting unit sets an isolation range according to a specifying operation with respect to the system diagram of equipment displayed on the screen. A master device registration unit extracts an isolation device present in the set range and registers it as a master device in the isolation list during editing. A slave device search unit successively selects a master device from the isolation list during editing, searches an isolation device which is in a relation of slave device with respect to the-selected master device from the history file, and displays a slave device list. A slave device registration unit inserts and places a slave device selected based on the selecting operation of the slave device list after the corresponding master device in the isolation list during editing, thereby completing the list.
