The two ports of FPNO-21 works as an embedded switch that supports Media Redundancy Protocol (MRP) without the requirement to use an external switch.

The S2 functionality, implemented in FPNO-21, makes it possible for two PROFINET controllers, one primary and one backup, to connect to the ABB Drives.

Easy to configure name via PLC programming environment as PROFINET station is named by index parameter (i.e. abbdrive-xx)

Easy to change the drive without special tools to rename the PROFINET station as PROFINET station is named as a part of drive’s backup file.

PROFINET “drive control” and “PROFIsafe” can be used by separate PLCs through Shared Device support. Shared Device enables accessing one drive from two controllers via one FPNO-21. (i.e.  one PLC to control the drive, other SafetyPLC for safety communication)

Support PROFIsafe over PROFINET. To use PROFIsafe, FSO-12 or FSO-21 with ACS880 is required.

Support SNTP protocol for the time synchronization.

Drive Composer Pro software can be used with FPNO-21 to perform a start-up or maintenance for ABB common architecture drives.
