Embodiment 1

[0028] In this embodiment, a general-purpose inverter control module based on the DeviceNet field bus is specifically provided, and the inverters that do not support the DevcieNet field bus are connected to the DevcieNet network. Such as figure 1 As shown, it includes an input and output interface, an embedded processor, a DevcieNet protocol conversion module, and a DevcieNet network interface. One end of the input and output interface is externally connected to a frequency converter, and the other end is connected to the embedded processor. The embedded processor and the DevcieNet protocol The conversion module is connected in communication, and the DevcieNet protocol conversion module is connected with the DevcieNet network interface and communicates with the DevcieNet network through the DevcieNet network interface to communicate with the PLC automation control system through the DevcieNet network to realize the function of automatic control. The frequency converter mention...

Abstract

The invention discloses a general frequency converter control module based on a DeviceNet field bus, and belongs to the technical field of communication control. The device comprises an input/output interface, an embedded processor, a DevcieNet protocol conversion module, and a DevcieNet network interface. One end of the input/output interface is externally connected with a frequency converter, the other end is connected with the embedded processor. The embedded processor is in communication connection with the DevcieNet protocol conversion module. The DevcieNet protocol conversion module is in communication connection with the DevcieNet network interface and is in communication with the DevcieNet network through the DevcieNet network interface. Due to the fact that the digital quantity input and output interface and the analog quantity input and output interface are provided, the module is directly connected with the frequency converter in a simple connection mode, control signals ofthe frequency converter are converted into DeviceNet field bus control signals, and all PLC systems supporting DevcieNet field buses can be conveniently connected to achieve automatic control.

Description

technical field [0001] The invention belongs to the technical field of communication control, and in particular relates to a general frequency converter control module based on DeviceNet field bus. Background technique [0002] With the development of industrial automation level, fieldbus has been widely used with the advantages of simplicity, reliability, economy and practicality. Among them, DeviceNet bus is a fieldbus standard used in automation technology. It was developed by Allen-Bradley Company of the United States and entered China. It has become one of the national standards for automatic control fieldbus in China. Frequency converter is an important stepless motor speed regulation drive equipment. DevcieNet fieldbus is only configured on some imported frequency converters. Most domestic general-purpose frequency converters, especially Some cheap inverters do not have DevcieNet field bus communication interface, so that they cannot be directly connected to the PLC a...
