2.1 General
The Anybus Communicator is designed to exchange data between a serial subnetwork and a higher level
network. Unlike most other gateway devices of similar kind, it does not have a fixed protocol for the
subnetwork, and can be configured to handle almost any form of serial communication.
The gateway can issue serial telegrams cyclically, on change of state, or based on trigger events issued by
the control system of the higher level network (i.e. the fieldbus master or PLC). It can also monitor cer-
tain aspects of the subnetwork communication and notify the higher level network 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 gateway 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 serial communication.
