3 Overview
3.1 Functionality
The KUNBUS Gateway is a protocol converter. It allows
communication between networks with different protocols.
Illustration1: Functionality as a slave
A Gateway consists of 2 gateway components that master one
specific protocol each. You can combine these gateway components
as you wish. This design offers you a high degree of flexibility, since
you can exchange the individual gateway components at any time.
The following gateway components are currently available as slaves:
– CANopen
– DeviceNet
– EtherCAT
– EtherNet/IP
– Modbus RTU
– Modbus TCP
– POWERLINK
– PROFIBUS
– PROFINET
– Sercos III
The gateway component for DMX can be operated as a master or
slave.
