CONTROLLER, CONTROL SYSTEM, AND CONTROL METHOD
First Claim
1. A control device that uses first data, transmitted thereto via a network, to generate second data for controlling a controlled object via the network, comprising:
- an adjustment unit that considers a maximum delay time tolerated by the network, and adjusts a time from a reception of the first data until a start of generating the second data using the first data; and
a delay compensation unit that is designed using a model of the controlled object and the maximum delay time tolerated by the network, and compensates delays in the first and second data that can occur in the network.

Abstract
A controller for using a first data item transmitted via a network to generate a second data item for controlling an entity to be controlled over the network, wherein the controller is characterized in being provided with: an adjustment unit for adjusting, with respect to the maximum delay time permissible on the network, the time by which generation of the second data item is started using the first data item after the first data item has been received; and a delay compensation unit, designed using a model of the entity to be controlled and the maximum delay time permissible on the network, for compensating for the delay of the first and second data items that can be generated using the network.

3. A control system that controls a controlled object via a network, comprising:
-
a control device that uses first data, transmitted thereto via a network, to generate second data for controlling a controlled object via the network, the control device including; an adjustment unit that considers a maximum delay time tolerated by the network, and adjusts a time from a reception of the first data until a start of generating the second data using the first data; and a delay compensation unit that is designed using a model of the controlled object and the maximum delay time tolerated by the network, and compensates delays in the first and second data that can occur in the network; and a field device having a timing adjustment unit that considers the maximum delay time tolerated by the network, and adjusts a timing of a manipulation of the controlled object based on the second data transmitted from the control device. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11)

12. A control method that uses first data, transmitted thereto via a network, to generate second data for controlling a controlled object via the network, comprising:
-
considering a maximum delay time tolerated by the network, and adjusting a time from a reception of the first data until a start of generating the second data using the first data; and compensating delays in the first and second data that can occur in the network by using a model of the controlled object and the maximum delay time tolerated by the network. - View Dependent Claims (13, 14, 15, 16, 17, 18)
