Abstract

Provided is a control device comprising a communication management part, a computation part, and a result output part. The communication management part is for managing data communication using cyclic communication conforming to a prescribed communication cycle with respect to a field network. The computation part is for measuring a propagation delay time from received data corresponding to actual measurement data for a propagation delay having been transmitted to the field network, and detecting an operation state of the field network using the propagation delay time measurement result. The result output part is for outputting the result of the detection performed by the computation part.
