The integration of control and monitoring systems often restricts more advanced monitoring algorithms to be used because of the limitation of hardware resource. This paper proposed a remote on-line model-based monitoring scheme, in which the monitoring and the control are implemented in different stations but synchronised through a Fieldbus network. Moreover, the synchronism period is adjustable so that it allows implementation of various monitoring tasks of different monitoring accuracy. This approach is demonstrated by applying it to a mechatronic control system. The implementation details are presented and the benefits of the approach are highlighted.
