Modbus TCP/IP Subsystem for Altera-Intel FPGA

Switch IP Core and Communication Processor for the Integration of Modbus TCP/IP Server on Altera-Intel FPGA

  • Simplifies Modbus TCP/IP connectivity for field devices with Altera-Intel FPGA
  • Optimized switch IP core and pre-installed software handle the entire protocol
  • Modbus TCP/IP and other industrial networks are supported by the same API
  • Fast and robust operation by hardware/logic support
Modbus TCP/IP Subsystem for Altera-Intel FPGA

Overview

Easy-to-Integrate Modbus TCP/IP Server Subsystem for FPGAs

  • Entire protocol is handled by pre-installed software, no need for any porting
  • Example project for fast hands-on experience
  • Adaptation to the application requirements by extensive configuration options
  • Large choice of supported FPGA families and sizes

Low Total Cost of Ownership

  • No dependency on special ASICs
  • Risk-free implementation thanks to Softing‘s consulting, integration, and pre-certification services
  • Re-configuration and extension possible even after production
  • Simple addition of further protocols

Pre-certified to Latest Standards

  • Compliant to current Modbus/TCP specifications
  • Tested against Modbus.org’s latest conformance test tool (version 3.0)

Fast and Robust Operation

  • Industrial switch IP core with cut-through forwarding and filtering (firewall)
  • Device application software is separated from protocol software
