Historically developed networks generally cause problems at some time in their lifespan.
Where previously a classical fieldbus like CANopen, PROFIBUS, or
DeviceNet was the preferred network, Ethernet-based bus systems are
nowadays. In addition, a protocol change from one fieldbus to
another also frequently occurs in many applications.
A complete exchange of the
communication modules is expensive or often not possible, as the
communication circuit board is a part of the control circuit board.
Communication gateways (or sometimes called “protocol converters”) were
developed as an investment protection. The gateway compresses all data
that the target network can transmit. Furthermore, it drops data that
cannot be transmitted or adds required data.
such as the KUNBUS Gateway family enables continuous and reliable communication
between different networks and systems. The KUNBUS Gateway converts all
data that the target network can transfer. It omits non-transferrable
data and adds necessary data in the new network. Thus, the operators can
transfer all necessary data from one closed network to another.
With this Gateway series KUNBUS offers a protocol converter that can be attached to DIN rails and detached again easily by
means of plug and play. The protocols themselves are located in compact
modules, whose housings are just 22.5 x 101.4 x 115 mm in size. The modules
are connected via a jumper to a gateway. The user can exchange the
protocol modules easily and conveniently to connect one network to
another. Customized solutions are also possible. The KUNBUS Gateway are
equipped with an integrated web server; program parts are updated via
FTP server. The maximum output of the series is three Watt; the voltage
tolerance ranges from minus 15 to plus 20 percent.
new modular KUNBUS Gateway System allows simple configuration of Gateways
by plug-in linkage or adaption by exchanging the module. By using a
jumper you connect two protocols to a complete gateway. A big
advantage of the Gateway is the reducing of stock-costs. Due to the
modular structure you can wait with the configuration till the time of
delivery to your customer.
