ACS/ACH 400 Direct N2 Bus Interface 4-1
Chapter 4 – Programming
This chapter describes the programming of the
ACS/ACH 400 drives for communications on
the N2 Bus. The reader should be familiar with
the ACS/ACH 400 drive and the Johnson
Controls Metasys system.
Programming of
the Drive
The ACS/ACH 400 drives are programmed
through the local programming panel. The
operation of the panel is described in detail in
the ACS/ACH programming manual.
Supported Features
An ACS/ACH 400 drive looks for the N2 Bus
protocol as a “virtual object” shown in
Figure:4-1 “ACS/ACH 400 Virtual Object”. A
virtual object is made up of:
• Analog Inputs
• Binary Inputs
• Analog Outputs
• Binary Outputs
• Internal values for Floating point,
Integer, and Byte values.
