Problems solved by technology

The most commonly used upgrade method is to use the JATG interface to reprogram the processor program. This method requires disassembling the device shell, or reserving a JTAG interface on the shell to upgrade the device. This update method requires recalling the device or Developers go to the site to update, especially inconvenient when updating in large quantities, which increases the update cost of the equipment and the time to market, etc.
There are also some special hardware circuits and interfaces for upgrading and updating in the equipment design, and these methods also increase the cost of the equipment.

Abstract

The invention provides a remote online data updating system of a soft PLC module. The system comprises a far-end EtherCAT main station, an EtherCAT bus, a storage module and an FPGA module. The invention also provides a remote online data updating method of the soft PLC module. The method comprises that the far-end EtherCAT main station sends update data upgraded remotely, an EtherCAT IP core module receives the update data transmitted by the EtherCAT bus, an NIOS II processor writes the update data in the storage module, and controls remote updating of the IP module, reconfiguration of the FPGA is initiated, and the FPGA is reconfigured by utilizing the update data.

Description

technical field [0001] The invention relates to a soft PLC module update system and method in the field of automation control, in particular to a remote online firmware data update system and method for the soft PLC module. Background technique [0002] Applying EtherCAT bus technology to the field of industrial automation control is an important development direction of current industrial control field bus technology. It has the characteristics of high speed and high data efficiency, and supports a variety of device connection topologies. Its slave nodes use dedicated control chip. [0003] Most of the EtherCAT devices currently on the market are implemented with a dedicated EtherCAT chip plus a microcontroller processor. When there is a defect in the design of the device software program, we need to upgrade the program of the microprocessor. The most commonly used upgrade method is to use the JATG interface to reprogram the processor program. This method requires disasse...
