PROBLEM TO BE SOLVED: To prevent the occurrence of a situation where, when a set value synchronized between plural compound machines and a server is changed by an individual compound machine, the set value is also changed in the other compound machines.SOLUTION: Compound machines 120a and 120b holding the set value and a set value management server 110 can be interconnected via a network 100. When a request to change the set value is inputted from a user to a compound machine 120a, the compound machine 120a makes an inquiry about whether the set value can be changed, to the set value management server 110. If the set value is a set value synchronized between the compound machines 120a and 120b, the set value management server 110 transmits to the compound machine 120a information to restrict the change. |
