Compute platforms are achieving incredible power in very small form factors. I’ve been contemplating where we could go with industrial applications built on Raspberry Pi. Then I saw this note from Hilscher. This is the world where that company plays. Here is a complete industrial communications application on the new M.2 format for PCI Express that adds real-time communications to PC-based systems.
In just a few minutes, you can connect PC-based devices, such IPCs, HMIs and robotics, to Real-Time Ethernet and Fieldbus networks. The comprehensive package has all necessary hardware and software components, including protocol stacks, device drivers and network connectors. The M.2 card can be simply installed in new and existing devices to connect with industrial automation networks on the fly.
PCI Express M.2, briefly named M.2, is smaller than the Mini PCI Express format and was designed for very thin computing platforms like notebooks and tablets. Since its introduction, automation manufacturers of PC-based systems, such as Industrial PCs, vision systems, robotics, and human machine interfaces (HMIs), have integrated M.2 sockets into their devices for one simple reason. The tiny M.2 format allows many add-in functions to be included into their systems in very tight spaces. Now, with this Hilscher offering, M.2 cards can provide real-time automation network connectivity.
M.2 formats come in various widths, lengths, and socket keys. For this first M.2 card release, Hilscher is using the A+E key socket arrangement, as that is the PCI Express specification’s generic form factor for connectivity add-ins, such as WiFi and Bluetooth. The M.2 2230 Key A+E card, with Hilscher product name CIFX M223090AE, is part of Hilscher’s cifX family of PC Cards. cifX PC Cards are intended for easy integration of a network interface and fast time-to-market of the manufacturers’ products and features.
At the heart of the M.2 2230 card is Hilscher’s netX 90 multiprotocol communication chip. M.2 card users can choose among loadable firmware for PROFINET IO-Device, EtherNet/IP Adapter, EtherCAT Slave and OpenModbus/TCP. Available in Q4 2020 is firmware for CC-Link IE Field Basic and Ethernet POWERLINK Slave. The appropriate network connector is included with delivery. There are adapters available from third-party vendors for other key formats, if required by the application. Additional firmware options, more card and key formats, and OPC UA and MQTT functionality will be released in the future.
Other benefits of the netX 90 ASIC include its small size, low power draw, reduced heat waste and extended temperature range. These features make CIFX M223090AE the smallest multiprotocol card in the market, at 22 mm X 30 mm, and allow it to operate in conditions from -20 deg C to +70 deg C. With its low power consumption, the M.2 2230 is ideal for energy saving applications.
Choosing the Hilscher M.2 card allows users to future-proof their designs. Hilscher continuously provides new firmware for Real-Time Ethernet, traditional Fieldbus and IIoT protocols. Besides a wide range of industrial protocols, Hilscher also provides device drivers for all major operating systems used in the industrial environment, including Windows, Linux, INtime, RTX, and QNX, as well as a C Toolkit for custom device drivers.
