POWERLINK master station

The invention provides a POWERLINK master station. The POWERLINK master station comprises a CPU and an FPGA; and the CPU comprises a CANopen protocol stack, an application layer and an industrial control middleware, and the FPGA comprises a POWERLINK protocol stack, wherein the application layer achieves communication connection with the POWERLINK protocol stack through the industrial control middleware and the CANopen protocol stack, and the industrial control middleware comprises a variable monitoring module, a periodic task management module and a variable mapping module. The industrial control middleware provides functions such as periodic task management, variable monitoring and variable mapping for POWERLINK protocol-based industrial control software, therefore, a user does not needto care about details of underlying hardware and an operating system and can concentrate primary energy on development of an application program. 本发明提供了种POWERLINK主站，包括：CPU和FPGA；所述CPU中包括：CANopen协议栈、应用层和工控中间件；所述FPGA包括：POWERLINK
