Summary:To provide an arrangement which allows use of time by using a conventional control counter.SOLUTION: A control system for factory automation has a first unit and a second unit exchanging data with each other, and synchronizing means for synchronizing a control counter held by the first unit with a control counter held by the second unit. Each of the units stores information which is the information shared by the units and relating to conversion for calculating time from a counter value of the counters of the units.SELECTED DRAWING: Figure 9 【課題】従来の制御用のカウンタを用いて時刻を利用可能な構成を提供する。【解決手段】ファクトリオートメーションの制御システムは、データを遣り取りする第１のユニットおよび第２のユニットと、クロックを用いて、第１のユニットが備える制御用のカウンタと第２のユニットが備える制御用のカウンタとを同期させる同期手段と、を備え、各ユニットは、ユニット間で共有される情報であって、当該ユニットのカウンタのカウンタ値から時刻を算出する換算に関する情報を格納する。【選択図】図９
