Lattice Semiconductor recently introduced their Sercos III real-time Ethernet solution. The Sercos III solution features the Lattice FPGA device. It is a low cost, low power FPGA-based alternative for engineers who need to implement flexible industrial networking solutions. Sercos is a digital bus that interconnects motion controls, drives, I/O, sensors and actuators for numerically controlled machines and systems. It is designed for the high-speed serial communication of standardized closed-loop real-time data over Industrial Ethernet.
The Sercos III real-time Ethernet evaluation kit features two boards (FPGA module and base board) and an optional expansion module. The low cost, low power solution is designed for test implementations and performance measurements of Sercos III slave devices based on the SERCON100S slave IP core in combination with the LatticeMico32 soft microprocessor and other optional system functions.
The FPGA module includes a LatticeECP3-35 FPGA, 8 MB Flash and 8 MB DRAM. The FPGA module can also be integrated as is into Sercos III slave devices. This will reduce cost and decrease the time to market for slave devices like I/O units or drives.
The base board features 16DI and 16DO (all with status LEDs), an RS232 interface, various switches and the standardized bi-color Sercos III diagnostic LED. The board is supplied with 24VDC or 5VDC. In addition, more functions or interfaces (such as analog I/O) can be added via the board’s socket for expansion modules.
The FPGA module is supported by the proven AUTOMATA Sercos III slave communication stack and test tools such as a master simulator for Windows XP. A sample implementation of the Sercos III I/O profile (FSP-I/O) is available.
