Embodiment Construction

[0050] Although the FF network has advantages that the traditional control network does not have, the control network at the present stage is still mostly the traditional control network, such as the DCS control network. If the existing traditional control network is completely dismantled and an FF network is built, many network resources will be wasted. In addition, because many users are still accustomed to the traditional mode of controlling the network.

[0051] Based on this, the present invention provides a solution, the basic idea of ​​which is: to connect the traditional network and the FF network through an interface device, so as to realize the control of the FF protocol equipment in the traditional network.

[0052] In order for those skilled in the art to have a better understanding of the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the drawings and embodiments.

Abstract

The invention discloses a control system comprising foundation fieldbus (FF) protocol H1 field-level network. The control system comprises a plurality of FF protocol H1-field network for supporting the FF protocol; a control network for supporting other protocols; and further an interface device for connecting the FF protocol H1 field-level network and the control network, acquiring on-site parameters and information of equipments in the FF protocol H1 field-level network, converting to the information that can be identified by the control network, and providing to the control network; wherein the control network calculates, converts the calculation results to FF protocol information and provides to the equipments in the FF protocol H1 field-level network. The invention discloses an interface device and a communication method at the same time. The invention realizes the information interchange between the equipments in the FF protocol H1 field-level network and the control network through the interface device, and realizes the control of the conventional control network to the equipments in the FF protocol H1 field-level network, so as to take full advantages of and expand the function of the conventional control network, and avoid wasting of resources.

Description

technical field [0001] The technical field of industrial automation control of the present invention relates in particular to a control system including FF (Foundation Fieldbus, Foundation Fieldbus) protocol H1 network segment, an interface device and a communication method based on the control system. Background technique [0002] FF is a bidirectional, serial, multi-node digital communication technology applied to the production site, between field devices, and between field devices and control devices. It has the characteristics of distribution, openness, interconnection and high reliability. FCS (Fieldbus Control System, Fieldbus Control System) adopts one-to-many two-way transmission signal, the digital signal adopted has high precision and strong reliability, and the equipment is always under the remote monitoring of the operator, which is controllable, and the operator can freely Select different brands of smart devices to interconnect according to needs, and the con...
