Rugged Linux box-PC excels at industrial fieldbuses

Nov 7, 2014 — by Eric Brown — 1,818 views

Ixxat’s ruggedized “Econ 100” DIN rail computer runs Linux on an ARM/FPGA Xilinx Zynq SoC, and supports multiple industrial Ethernet and fieldbus protocols.

Ixxat Automation, which was acquired last year by HMS Industrial Networks, has spun a multi-protocol, industrial PC that supports a variety of fieldbus and industrial Ethernet standards. The Econ 100 “combines the machine control expertise from Ixxat with the fieldbus and industrial Ethernet capabilities of HMS Anybus technology,” says Ixxat. The Econ 100 offers extended temperature support and is designed for industrial applications ranging from “small material handling devices to complex robot-based systems for medical use,” says the company.

The Econ 100 runs Linux on the Xilinx Zynq-7020 system-on-chip, which combines dual, 667MHz to 1GHz ARM Cortex-A9 cores with a relatively low end Artix-7 class FPGA. The system ships with 256MB DDR3 RAM, expandable to 1GB, as well as a 256MB SD card, expandable up to 32GB.

Standard interfaces include gigabit Ethernet and EtherCAT 10/100 networking ports, as well as two CAN ports and two USB ports. Serial and DVI ports are optional.

An optional expansion board supports a variety of optional HMS Anybus CompactCom plug-in modules. The modules are available for all popular fieldbus and industrial Ethernet networks, and are supported via an Anybus programming interface, says Ixxat. The expansion board also supplies 24 analog and digital I/Os for connecting sensors and actuators, as well as variety of serial interfaces. In addition, the board integrates 512MB NVRAM for data security and reliability.

The Econ 100 has a rugged, 154 x 105 x 72mm metal case with IP20 protection. It’s available with DIN rail mounting, as well as a desktop case. The computer supports an extended temperature range of -40 to 60°C, according to the press release and -40 to 70°C, according to the data sheet.

The system offers a wide-range 9-32V power supply and runs at between 4-5 Watts, says the company. The Econ 100 is also available as a board-level product that can be integrated in existing applications OEM versions. Specific hardware and software customizations are available upon request.

The system’s Linux–based application development kit includes an “extensive” BSP with interface drivers, sample applications, and the selected protocol software pre-installed on an SD card. The Econ 100 supports C/C++ programming, and ships with a Soft-PLC programming environment “in collaboration with Copalp, which is consistent with IEC 61131-3 for simple programming and configuration of control applications,” says Ixxat. The software supports protocols including CANopen, EtherCAT, Powerlink MN/CN, PROFINET, and EtherNet/IP.
