Zusammenfassung:To reduce the communication load associated with duplication, and realize data transmission that does not require consideration of switching of the duplicated data transmission destination system in a device.SOLUTION: There is provided a communication system including a first aggregator configured with an active IP address for receiving data from a device and a second aggregator configured with a standby IP address that is not used to receive data from the device, and each of the first aggregator and the second aggregator includes system determination means for determining whether the system is an active system or a standby system, state determination means for determining whether the own state is normal or abnormal, and address setting means for setting either the active IP address or the standby IP address on the basis of the determination result by the system determination means, the determination result by the state determination means, and the state of another aggregator different from itself.SELECTED DRAWING: Figure 2 【課題】二重化に伴う通信負荷を軽減する。また、機器において、二重化されたデータ送信先の系の切り替えの考慮が不要なデータ送信を実現する。【解決手段】機器からのデータを受信するための稼働系用IPアドレスが設定された第1の集約器と、前記機器からのデータの受信に用いられない待機系用IPアドレスが設定された第2の集約器とを有する通信システムであって、前記第1の集約器及び前記第2の集約器は、自身が稼働系又は待機系のいずれであるかを判定する系判定手段と、自身の状態が正常又は異常のいずれであるかを判定する状態判定手段と、前記系判定手段による判定結果と、前記状態判定手段による判定結果と、自身とは異なる他の集約器の状態とに応じて、前記稼働系用IPアドレス又は前記待機系用IPアドレスのいずれかを設定するアドレス設定手段と、を有する、ことを特徴とする。【選択図】図2
