Fieldbus Control with Embedded Fieldbus
System Overview
The drive can be connected to an external control system via
embedded eldbus. The embedded eldbus supports Modbus
RTU, BACnet
®
, Metasys
®
N2 and APOGEE
®
FLN Protocols.
Embedded eldbus connection is either RS-232 (control
panel connector X2) or RS-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). RS-485 is designed for a
multipoint application (a single master controlling one or more
slaves).
