Abstract

The invention provides a Profibus-DP communication manager capable of supporting a programmable algorithm. The Profibus-DP communication manager comprises a redundant Ethernet communication module used for carrying out data communciation with a master controller in a DCS (Distributed Control System) through a communication protocol; a Profibus-DP equipment communication module used to be in data communication with Profibus-DP equipment; a polling scheduling module used for distributing inputted / outputted data to other modules; and an IEC (International Electrotechnical Commission) standard algorithm execution module used for processing the received data. By use of the embodiment of the invention, the computational burden of the DCS master controller can be reduced, and the response time of the Profibus-DP communication manager can be shortened, thus the practicability and flexibility of the DCS can be increased.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a Profibus-DP communication management machine supporting programmable algorithms. Background technique [0002] Profibus-DP is an international, open, field bus standard that does not depend on equipment manufacturers. It is widely used in manufacturing automation, process industry automation and automation in other fields such as building, transportation and power. [0003] Profibus-DP is also a field bus technology used for automated workshop level monitoring and field device level data communication and control. It can realize the distributed digital control and field communication network from the field equipment layer to the workshop level, thus providing a feasible solution for the realization of the field equipment intelligence of the comprehensive automation of the factory. [0004] Technically, the existing Profibus-DP communication equipment only realizes the mechanism...
