Problems solved by technology

At present, some domestic equipment uses both Siemens S7-300 / 400PLC and Mitsubishi Q series PLC, which makes it difficult to manage the two PLCs in a unified manner. The two PLCs operate independently and cannot share data, which makes the coordination of the two equipment Greatly reduced, so that the quality of production products and other issues are reduced, causing unnecessary losses
[0004] Due to some intractable problems with the current equipment
The equipment can only be produced manually or mechanically, so that some aspects will reduce the degree of automation

Embodiment Construction

[0022] For the convenience of description, spatially relative terms may be used here, such as "on ...", "over ...", "on the surface of ...", "above", etc., to describe the The spatial positional relationship between one device or feature shown and other devices or features. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if an implement in a drawing is turned upside down, an implement described as "above" or "above" other implements or formations would then be oriented "below" or "over" the other implements or formations. under other devices or structures". Thus, the exemplary term "above" can encompass both an orientation of "above" and "beneath". The device may be oriented in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptions used herein interpreted accordingly...

Abstract

The invention relates to the technical field of converters, in particular to a PROFIBUS-DP and CC-Link protocol converter. The converter comprises a PROFIBUS board card, a CC-Link board card and an MCU chip. The PROFIBUS board card is used for receiving and sending the data of the Siemens S7-300 / 400 PLC. The B40 CC-Link board card receives and sends the data of the Mitsubishi Q series PLC. The PROFIBUS board card and the CC-Link board card are respectively in communication with the MCU chip through the USART1 and the USART2. According to the protocol converter, partial data fusion of two industrial control PLCs of Mitsubishi and Siemens can be effectively solved, so that the production quality, efficiency and the like are improved, and popularization and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of converters, in particular to a PROFIBUS-DP and CC-Link protocol converter. Background technique [0002] PROFIBUS is a field bus standard used in automation technology. It was promoted by 14 companies including German Siemens and five research institutions in 1987 [1]. PROFIBUS is the abbreviation of PROcess Field BUS. PROFIBUS and PROFINET used in industrial Ethernet are two different communication protocols. Profibus stands for "Process Field Bus" and DP stands for "Distributed Device". "CC-link" is the abbreviation of "Control&Communication-link". It is a system that connects scattered I / O modules, special high-function modules, etc. through communication cables, and controls these corresponding modules through the CPU of the PLC. [0003] As a data exchange device, DP / CC protocol converter uses PLC as the controller to complete data sharing through data transmission and reception. At present, some...
