I M GOING TO IMPLEMENT THE INDUSTRIAL ETHERNET POWERLINK PROTOCOL WITH FPGA, SO PLEASE LEARN THE BAS

Implementing PowerLink on FPGA, in fact, does not require too much hardware knowledge (software solutions), there are many open sources, as long as you build a soft core project according to Wang Jinqiu's tutorial (about 3-4 hours of learning time), the rest of the software porting is also convenient, and ready-made examples can be used directly. The rest of the application modifications and applications are mainly C language programming, so what is needed is mainly C language programming basics.

At present, the open source FPGA project has DirectIO that can be directly used for IO applications, such as IO acquisition, AD, DA applications, or some simple control such as stepper motor control.

PCP AP Engineering, which is used to handle PowerLink communication, AP is used for complex applications such as servo motor control, complex PLC control. The PCP communicates with the AP via SPI, 8 16-bit parallel port.

OpenMac project, which is used for PowerLink communication, can add your own defined interface with AP, such as I2C, AHB and other interfaces.

You'd better build a basic communication network according to the official example, and then modify it based on it, and do some other communication experiments, so that it is faster.

Do you want to add your own private protocol on top of your industrial Ethernet switches?

What kind of main station do you use, there are many types of this situation:

The primary site times out and loses packets.

Packet conflicts.

Wireshark issues with the Omnipeek+ Ethernet analysis module.

FPGA (Field Programmable Gate Array) is a product of further development on the basis of programmable devices such as PAL, GAL, and CPLD. It appears as a semi-customized circuit in the field of application-specific integrated circuits (ASIC), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of gates of the original programmable devices. The uses of FPGAs are as follows:

Circuit design: connection logic and control logic are the areas where FPGA plays a relatively large role in the early stage, and it is also the cornerstone of FPGA applications, which is also an important role of FPGA.

System-level application: The system-level application is the combination of FPGA and traditional computer technology to realize an FPGA version of the computer system, such as using Xilinx V-4, V-5 series FPGA, to achieve embedded Power PC CPU, and then cooperate with various peripheral functions to achieve a basic environment, on this platform to run Linux and other systems. The system also supports a variety of standard peripherals and functional interfaces (e.g., image interfaces), which is very helpful for quickly building FPGAs into large systems.

Isn't it amazing that most of the functions of digital circuits can be realized, and all the circuits that can only be completed with many ICs in the past can be made into FPGA, and they can be modified at will.

FPGA is an abbreviation for Field Programmable Gate Array, which is actually a semiconductor chip that can be programmed using some special hardware description language (e.g., VHDL, etc.). C, VB, etc. are high-level programming languages. Basically, FPGAs and C, VB, etc. are completely unrelated different concepts.

If there is anything to do with it, it can only be said that they are all objects of study in the field of computer science.

Ethernet IP with 1588,1

EtherCAT is similar to 1588 with an accuracy of 1

PowerLink, with SoC frame + measurement compensation, can be reached, and the total accuracy is also within 1 considering the jitter introduced into the hub.

There are many Ethernet chips, EN28J60 and so on.

However, to control it with FPGA, it may be **complicated, unless you run the NIOS soft core.

The EtherNetBlaster configuration FPGA is an Ethernet interface.

FPGA comes with the IP core of the GE port, which can be directly instantiated and called, and I have never seen it written, and there are several mode options in it when instantiating, choose the mode you need.

Because FPGA is a microprocessor for parallel processing, compared to other serial processors, it is very fast, even so, FPGA can also be multiplied to a very high frequency, and in addition to the differential signal transmission of 1km bandwidth, then the bandwidth is high and the speed is fast, and the required chips must also be parallel!
