NI Introduces Test Solution for 802.11ax High-Efficiency Wireless

National Instruments, the provider of platform-based systems that enable engineers and scientists to solve the world’s greatest engineering challenges, announced today an early access version of the WLAN Measurement Suite with support for the IEEE 802.11ax (draft 0.1) high-efficiency wireless draft standard. The WLAN Measurement Suite, combined with NI’s RF vector signal transceiver (VST), empowers engineers to measure the performance of their 802.11ax designs confidently in the presence of significant new changes to the 802.11 physical layer specification.

The WLAN Measurement Suite gives researchers, engineers and technologists the power and flexibility to generate and analyze a wide range of 802.11 waveforms, such as 802.11a/b/g/n/j/p/ac/ah/af. Now, with the measurement suite’s latest update targeting 802.11ax, these users can speed up development work on 802.11ax devices. The software supports key features of 802.11ax including narrower subcarrier spacing, 1024-QAM and multi-user orthogonal frequency division multiple access (OFDMA). The updated measurement suite also includes LabVIEW system design software example code to help engineers automate WLAN measurements quickly and easily.

“The fast pace of evolving wireless standards demands instrumentation that can evolve at the speed of software,” said Charles Schroeder, vice president of RF marketing at NI. “Our support for the latest 802.11ax draft standard in the WLAN Measurement Suite is part of the evolution of a platform that scales with changing connectivity standards and provides our customers with superior RF performance in lab and production environments.”

NI’s platform-based approach helps ensure that engineers can update their existing PXI RF test systems to support 802.11ax device testing with a simple software update, and continue to do so as the 802.11ax standardization process evolves. Engineers can take advantage of this smarter approach to RF test to help lower their cost of test and better prepare for future connectivity and cellular standardization initiatives, such as 5G.


AnyBus Edge Gateways enable communication between IT-systems and the factory floor

The new Anybus .NET gateways enable real-time data from industrial machinery to be presented to .NET-based IT applications. This means that .NET programmers can get data directly from a PLC system on the other side of “the edge” to be used in applications for statistics, analysis or maintenance. The first .NET gateways are available for PROFIBUS and PROFINET.

A quick and easy way to realize IIoT:
The basic prerequisite for Industrial IoT is that industrial applications are able to communicate with IT systems. However, the operational technology (OT) on the factory floor uses fieldbus and industrial Ethernet networks, which are designed for real-time communication by default separated from the IT-infrastructure.

The Anybus .NET gateways address this situation by acting as translators which send and receive data between PROFIBUS- or PROFINET-networks and IT platforms using .NET as a framework.

The communication is set up in a couple of minutes and the .NET gateways are therefore a very fast way to realize IIoT.

The result is that IT systems get unprecedented access to real-time data from the factory floor which enables predictive maintenance, KPI-follow-up, machine analytics, data mining, big data processing, production statistics and much more – without interfering with the industrial processes.

The solution can be used for a wide range of use cases, from simple transfer of KPI values, advanced messages with structured data types, or ultra-fast transfer of I/O data for “big data.”

How it works:
In addition to connecting the data from the industrial processes to the IT-systems, the .NET gateways make the data understandable on the IT-side. The information exchange between the Operational Technology (OT) side and the Information Technology (IT) side is defined in a spreadsheet template which defines how the data is mapped, tagged and presented to IT-applications.

The spreadsheet is uploaded to the HMS code generator which automatically creates a customized high level C# API (events and Post methods) that is easy to integrate directly into a .NET application. It also generates a customized GSDML file for the PLC.

New IIoT gateways from HMS allow industrial equipment to communicate with power grids

HMS Industrial Networks now introduces a new family of Industrial IoT gateways for Smart Grid applications. The Anybus SG-gateways enable communication between industrial applications and energy protocols.

This communication is the very basis for the so called “Smart Grid” where power plants and energy equipment are interacting with industrial applications. The SG-gateways are yet another example of how HMS realizes the Industrial Internet of Things.
Anybus SG-gateways make the Smart Grid possible
The new SG-gateways enable communication between industrial devices running Modbus, PROFIBUS, PROFINET, EtherNet/IP, or M-Bus and energy protocols (IEC61850 and IEC60870-5-104).

This means that a power plant control room which is using the IEC protocols, can connect to industrial devices such as generators, drives, filters and protection equipment.

Since the SG-gateways can act both as a master and slave, it is also possible to connect Intelligent Electronic Devices (IEDs) which communicate over IEC-standards, to industrial networks, allowing them to be controlled by PLCs from e.g. Siemens, Rockwell or Mitsubishi.

Moxa introduces Smart Remote Data Acquisition Devices with Wi-Fi

Moxa has announced a new data acquisition solution that brings greater versatility for the Industrial Internet of Things (IIoT). The new ioLogik™ 2542-WL1 and ioLogik 2512-WL1 both feature 802.11a/b/g Wi-Fi connectivity, which will serve the growing number of devices and M2M applications that require wireless communication. The ioLogik 2542-WL1 supports analog I/O connections over Wi-Fi, whereas the ioLogik 2512-WL1 supports digital I/O connections over Wi-Fi.

With the addition of these two models, Moxa now offers a range of flexible data acquisition solutions for wired Ethernet, Wi-Fi, 2G GPRS, and 3G HSPA networks. “We want to make it as easy as possible for industrial users to collect and share sensor data in different environments and circumstances,” said Wenyuan Niu, Product Marketing Manager. “Wi-Fi is becoming a useful and popular mode of communication both on the factory floor and in remote locations. Our new wireless models will help users leverage Wi-Fi for their data acquisition requirements.”

Both ioLogik units feature automatic tag generation and reporting for connected sensors and devices. This function enables operators to monitor a large number of field devices with great efficiency, and also works in conjunction with Moxa’s MX-AOPC UA Server on the cloud to minimize network bandwidth and latency.

Moxa to Introduce 8/16-port Redundant Modbus Gateways

MGate_MB3660.jpgMoxa has announced the release of the MGate MB3660MGate_MB3660 series of high density Modbus gateways that convert between the Modbus TCP and Modbus RTU/ASCII protocols. The gateways can be accessed by up to 256 TCP master/client devices, or connect to 128 TCP slave/server devices simultaneously without decreasing performance. Each serial port can be connected with up to 31 serial devices. In addition, the MGate MB3660 gateways are designed with dual Ethernet interfaces and dual power modules for addressing redundancy concerns. This strong collection of benefits make the MGate MB3660 gateways a perfect fit for power monitoring, environmental monitoring, and data center infrastructure management (DCIM) in large-scale industrial applications.

“The main characteristic shared by these applications is that they are required to collect data from a large number of Modbus devices. The MGate MB3660 can actively communicate and collect data with end devices continuously to obtain up-to-date information; a SCADA system can retrieve all of the data from end devices in just 1 second. By using a high density Modbus gateway, you no longer need to use large numbers of low-port-density Modbus gateways, which come with the added burden of extra wiring and installing hardware and software one gateway at a time,” said Sean Chen, product manager of Moxa’s Industrial Ethernet Gateway division. “Moxa’s MGate MB3660 is designed with innovative command learning, which allows the gateways to actively and continuously retrieve data from Modbus devices in parallel through all serial ports; you won’t even need to key in one Modbus command, resulting in a dramatic reduction in the amount of time a Modbus device needs to wait to be accessed.”

The MGate MB3660 Modbus gateways support redundancy for both the power input and Ethernet connection, and come with dual AC or DC power inputs built in for power redundancy, and dual Ethernet ports (that support the same IP or different IPs) for network redundancy. In addition, the MGate MB3660 series isolation model provides 2 kV isolation protection suitable for power substation applications.
