The control function sections are connected through a network, and a plurality of logical communication paths are set in the network. Logical connection relationship using independent logical communication paths are established for respective inter-control processes, so that inter-control process communications are executed using packets at high speed. The communication packets are sent to the logically connected control processes, thus realizing control functions of the elevator system.
