A network system includes a synchronous master device to output a cooperative-operation timing signal in a cooperative-operation cycle, a time master station connected to a network, and a time slave station connected to the network. The time master station includes a master clock to count a time, and a master generation unit to generate master cooperative-operation-time information on the basis of the cooperative-operation timing signal and the time counted by the master clock. The time slave station includes a slave clock to count a time, and a slave generation unit to generate slave cooperative-operation-time information on the basis of the master cooperative-operation-time information and the time counted by the slave clock.
