1.1.2 Introduction
The frequency converter control board is program selectable for use with the Johnson Controls Metasys N2 protocol. Metasys N2 is a master/slave control network.
The physical layer is RS485 compatible, half duplex 9600 baud shielded twisted pair. The N2 software protocol is designed to be general in nature to accommodate
the unique properties each device type may have. Every device connection to the N2 network can be thought of as a small data manager. Data points in the
database are classified as analog I/O (floating point), binary I/O or integer data points - floats, integers or bytes. Each data type has its own unique structure
defined in the Metasys N2 system Protocol Specification for Vendors.
The information in this manual is intended to provide you with comprehensive information on how to install and set up the frequency converter for communication
over a Metasys network.
For specific information on operation of the drive, refer to the AF-600 FP Operating Instructions
