Running Modbus TCP Reference Design on SmartFusion2 Using IwIP and FreeRTOS

IntroductionMicrosemi® offers a reference design for SmartFusion2 SoC FPGA devices that demonstrates the tri-speed ethernet medium access controller (TSEMAC) features of the SmartFusion2 SoC FPGA andimplements the Modbus Protocol. The reference design runs on the SmartFusion2 AdvancedDevelopment Kit. This demo guide describes:

• Usage of SmartFusion2 TSEMAC connected to a serial gigabit media independent interface (SGMII) PHY.

• Integration of SmartFusion2 MAC driver with the lwIP TCP or IP stack and the FreeRTOS Operating System.

• Application layer with industrial automation protocol, Modbus on TCP or IP.

• How to run the reference design

The microcontroller subsystem (MSS) of the SmartFusion2 SoC FPGA has an instance of the TSEMACperipheral. The TSEMAC can be configured between the host processor and the Ethernet network at thefollowing data transfer rates (line speeds):

• 10 Mbps

• 100 Mbps

• 1000 Mbps

Refer to the UG0331: SmartFusion2 Microcontroller Subsystem User Guide for more information on theTSEMAC interface for SmartFusion2 devices.

Using the Modbus ProtocolModbus is an application layer messaging protocol present at the level seven of the open systemsinterconnection (OSI) model. It enables client or server communication between the devices connectedin different types of buses or networks. It is a service protocol that offers many services specified by thefunction codes. The Modbus function codes are elements of Modbus request or reply protocol data units.The components of the Modbus protocol include:

• TCP or IP over Ethernet

• Asynchronous serial transmission over a variety of media

– Wire

• EIA/TIA-232-E

• EIA-422

• EIA/TIA-485-A

– Fiber

– Radio

• Modbus PLUS, a high-speed token passing networkSup
