Zusammenfassung:To provide a server device, a communication device, and a control system that can more stably perform control via a network.SOLUTION: According to this embodiment, a server device includes a communication unit, a determination unit, and a control calculation unit. The communication unit sequentially receives a plurality of first packets each including the same first signal for each of a plurality of different pieces of connection information via a network. The determination unit determines whether the first signal included in the first packets has been received already. The control calculation unit generates a second signal corresponding to the first signal if the reception has not been done yet based on the determination.SELECTED DRAWING: Figure 1 【課題】本実施形態における課題は、ネットワークを介した制御をより安定的に行えるサーバ装置、通信装置、及び、制御システムを提供する。【解決手段】本実施形態によれば、サーバ装置は、通信部と、判定部と、制御演算部と、を備える。通信部は、複数の異なる接続情報毎に同一の第1信号をそれぞれ含む複数の第1パケットを、ネットワークを介して順に受信する。判定部は、第1パケットに含まれる第1信号が受信済みであるか否かを判定する。制御演算部は、判定に基づき、受信済みでない場合には、第1信号に応じた第2信号を生成する。【選択図】図1
