major enhancement to the X-gateway
family from HMS Industrial Networks releases 10 completely new
designed CANopen master (manager) gateways in small slim-line housings. Using
built-in dual port Ethernet, the new designs allow any CANopen enabled device
with slave functionality to communicate with almost any other fieldbus or
industrial Ethernet network.
"What we have done is redesign the
X-Gateway to centralize the application configuration and to slim down its physical
profile so it takes up less space in the panel," says Jason Block, a Channel
Manager for HMS Industrial Networks, Inc. "But the most unique
aspect of the product is support for dual port Ethernet with all of our gateway
For engineers designing systems, dual
port technology will keep the Ethernet backbone a little slimmer. If there is a
need to integrate other fieldbus technologies into an existing Ethernet architecture,
this approach avoids adding more bulk to the network by requiring additional
external switches. Building the switch into the gateway product itself allows
use of more linear and ring-based topologies, versus the standard star
topologies used in most Ethernet installations.
"Dual port Ethernet provides greater
network integrity when used in ring topologies as the ring configuration
dual paths to devices. Failure of a single switch can no longer
compromise entire segments of a network," says Block.
With all of the new Ethernet-based gateways supporting
dual port technologies, users can more fully leverage the advantages of the Ethernet
"We have actually had CANopen slave support
for several years where users could take lower level networks and integrate
them up to CANopen," says Block. "But with the CANopen master, we can take all
of these CANopen field devices and bring those up into higher level
The CANopen gateway series includes versions
for all popular fieldbuses such as Profibus, DeviceNet, Modbus and ControlNet.
Support for industrial Ethernet includes the Profinet, EtherNet/IP, EtherCAT
and Modbus-TCP protocols.
Embedded into a small plastic housing, the
slim-lined devices for standard DIN rail mounting and 24 Volt power supply.
Based on the Anybus communication modules, the CANopen X-gateways act as
intelligent links between two industrial networks. On the CANopen side, they always
function as a master (manager), while they work as slaves (servers) on the
uplink network side.
The implementation is based on HMS NP30
microprocessor and is certified by CAN in Automation (CIA) for full conformance
to the CANopen DS 301 v4.0.2 standard.
the configuration of the CANopen master interface, any standard CANopen
configuration tool can be used. The uplink fieldbus or Ethernet slave interface
is configured with a standard device description file (GSD / EDS) and the
standard engineering tool of the PLC. No programming is required. The gateways transmit
I/O data completely transparent between the two networks. I/O data from the
uplink fieldbus or Ethernet network is mapped into CANopen PDOs and vice versa.
Future revisions of the Anybus gateway will
include an SD memory card slot, beginning in Spring 2011. The memory card will
allow users to centralize intelligence, so that one person retains ownership of
the configuration intelligence. Using the SD memory card, users will be able to
port applications across multiple devices, and users will be able achieve transferability
of applications throughout a machine or multiple user installations. Instead of
multiple users needing the configuration utilities, a SD memory card with the
configuration already on the card will be inserted into the gateway.
