Fieldbus control
Contents of this chapter
The chapter describes how the drive can be controlled by external devices over a
communication network using embedded fieldbus.
System overview
The drive can be connected to an external control system via embedded fieldbus.
The embedded fieldbus supports Modbus RTU, BACnet
®
, Metasys
®
N2 and
APOGEE
®
FLN protocols.
Embedded fieldbus connection is either RS-232 (control panel connector X2) or
EIA-485 (I/O terminals 23…26). The maximum length of the communication cable
with RS-232 is restricted to 3 meters.
• RS-232 is designed for a point-to-point application (a single master controlling
one slave).
• EIA-485 is designed for a multipoint application (a single master controlling one or
more slaves).
