1.2 Anybus Communicator CAN Concept
1.2.1 General
The Anybus Communicator is designed to exchange data between a subnetwork, running CAN, and a
higher level network. The CAN protocol uses frames, that are individually configurable, offering great
flexibility.
Through the configuration of the CAN frames, the Communicator will adapt to a predefined CAN net-
work. It will be possible to send data to and receive data from the subnetwork, but also to act as a relay
for data on the CAN subnetwork.
The Communicator can issue frames cyclically, on change of data, or based on trigger events issued by
the control system of the higher level network (i.e. the fieldbus master or PLC) or by the CAN network.
It can also monitor certain aspects of the subnetwork communication and notify the higher level net-
work when data has changed.
An essential part of the Anybus Communicator package is the Anybus Configuration Manager, a Win-
dows™ application which is used to supply the Communicator with a description of the subnetwork
protocol. No programming skills are required; instead, a visual protocol description-system is used to
specify the different parts of the CAN frames.
