Abstract

The invention provides a fieldbus control system based on a Siemens controller and an Omron controller and belongs to the field of automatic control. The problem is solved that at present, the fieldbus control system based on the Siemens controller and the Omron controller cannot be established. The fieldbus control system comprises an upper monitoring PC, an upper master control system, a field lower control subsystem, a protocol converter, a field monitoring PC and several field devices. The upper master control system is a Siemens PCS7 system, and the Siemens PCS7 system adopts a PROFIBUS-DP fieldbus communication protocol. The field lower control subsystem is an Omron PLC system, and the Omron PLC system adopts a DeviceNet fieldbus communication protocol. The protocol converter is a gateway PD-100S. The upper monitoring PC and the Siemens PCS7 system are connected via Ethernet, the Siemens PCS7 system and the gateway PD-100S are connected through a PROFIBUS-DP bus, the Omron PLC system and the gateway PD-100S are connected through a DeviceNet bus, the Omron PLC system and the field monitoring PC are connected via Ethernet, and the several field devices are respectively connected with input terminals of the Omron PLC system.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a fieldbus control system based on a Siemens controller and an Omron controller. Background technique [0002] Fieldbus is a bi-directional all-digital communication bus from the control room to field devices. The field bus control system is an open interconnection model, which can be combined with Ethernet to realize remote monitoring, control, debugging, diagnosis, etc. through the Internet. Compared with DCS and PLC remote I / O, Fieldbus Control System FCS (Fieldbus Control System) realizes the local collection, local processing and local use of detection and control information by directly digitizing a large number of on-site detection and control information , so that many control functions are moved from the control room to the field equipment. While the system accuracy is improved, the information of the field equipment is increased by dozens of times, which can ...
