The new IXXAT CAN@net NT 200 is a CAN-to-Ethernet gateway which allows users to connect CAN and Ethernet. Thanks to its two operating modes, CAN@net NT can be used as CAN-Ethernet-CAN bridge and as CAN-to-Ethernet gateway. Equipped with two CAN interfaces, it supports an even wider range of use cases compared to the well-known CAN@net II.
Linking of CAN networks
One of the key features of the CAN@net NT – which is especially useful in e.g. building automation – is the ability to separate CAN networks that are distributed over large areas. CAN@net NT couples the CAN networks via a backbone Ethernet system, allowing existing infrastructures to be used. This segmentation also increases the reliability and stability of the overall system.
Enables remote access
Designed for high performance in harsh environments, another common application for CAN@net NT is remote access to CAN networks via Ethernet – e.g. in wind power plants or in the manufacturing sector. CAN@net NT enables service staff to get access to plants all around the world, simplifying control, service and monitoring of CAN-based plants, reducing costs and downtime significantly.
Besides the bridge operation, linking two CAN networks via Ethernet, the CAN@net NT 200 can also be directly accessed from Windows, Linux, VxWorks or QNX based systems as well as from embedded systems, by using a simple ASCII protocol over a standard TCP/IP socket.
CAN@net NT supports all CAN baud rates from 5 kBit/s to 1 Mbit/s, as well as simultaneous use of 11 and 29 bit identifiers. The TCP/IP-based protocol ensures that no CAN messages are lost when transmitted over Ethernet. The device configuration is easily made by using a Windows configuration tool.
More variants of the CAN@net NT, with PC interface operation mode, 4 CAN channels and CAN FD support will soon be released.
Adding to the existing and proven IXXAT IEEE 1588 solutions, HMS now presents protocol software for IEEE 802.1AS – the first commercially available software package for highly accurate time synchronization of AVB and TSN networks.
IEEE 802.1 AS is an adapted version of the IEEE 1588 profile – specially designed for AVB and TSN systems (audio/video broadcasting and time sensitive networking). As the most important core technology for AVB and TSN systems, IEEE 802.1AS enables high-precision time synchronization of devices and systems.
Using the IXXAT IEEE 802.1AS protocol software, customers benefit from a proven and tested software package as well as from a professional product maintenance and further development.
The 802.1AS protocol software offered by HMS comes as ANSI C code – inspired by MISRA-C – and has a modular structure with a clear separation of the media dependent and media independent layers. This enables easy porting and fast implementation into various target systems. As a time-aware, slave-only end station, the software is the receiver of time-synchronization information provided by a grandmaster and enables synchronization of local Real Time Clocks (RTCs). The software supports the Best Master Clock algorithm, which can be optionally disabled.
In addition to meeting the requirements of AVB and TSN systems, special needs within automotive systems are supported such as fast synchronization times (< 1 microsecond within one second) and optimization of memory usage.
Besides other IXXAT IEEE 1588 products such as the IEEE 1588 protocol software, the IP Core and the manager tool, HMS also offers a wide range of services based on the deep experience in the IEEE 1588 area. HMS assists the customers in all phases of the development process, from consulting and specification, to implementation, target adaptation and testing of the final product.
The following procucts have entered the limited phase:
Product lifecycle policy
HMS Industrial Networks (HMS) develops products that are meant to stay on the market for a long time, typically more than 10 years. The products are designed to be used in industrial applications, which brings high demands on reliability and availability. Product life times are influenced by many factors such as component availability and technology development. HMS always strives to keep the products up-to-date with maintained backwards compatibility.
In order to manage the products in a structured way during their lifetime, HMS has established a product lifecycle policy over a series of product lifecycle phases. Within this scope, HMS is committed to notify customers of any changes in product lifecycle status well in advance, in order for customers to be able to plan their operations in an efficient way.
The key element of the lifecycle policy is that HMS will always notify customers at least 24 months before a product in the Active phase becomes obsolete.
