1. About the Anybus Communicator for

PROFIBUS

The Anybus Communicator for PROFIBUS acts as a gateway between virtually any serial application

protocol and a PROFIBUS DP-based network. Integration of industrial devices is enabled without loss

of functionality, control and reliability, both when retro-fitting to existing equipment as well as when

setting up new installations.

Subnetwork

The Anybus Communicator can address up to 31 nodes, and supports the following physical standards:

•RS-232

•RS-422

•RS-485
