The IPS (Integrated Protection Systems) Communication Application Note contains valuable information for anyone trying to establish serial communication to Beckwith Electric's IPS family of generator or transformer protection relays.

BECO2200 is just one of Beckwith Electric's serial communication protocols. BECO2200 has been incorporated in the M-3420,
M-3520, M-3430, M-3440 and M-3310 line of protective relays. Technical information on this protocol can be found in the BECO2200 Communication Protocol document.

Communication database information for the M-3520 can be found in documents that support various protocols as listed in the title
BECO2200 & MODBUS Comm. Database (Device I.D. = 39).

MODBUS protocol is supported on the
M-3520 control. See the IPS Application Note and the communication database document for more information.

IPScom, Beckwith Electric's PC based communication software package provides an easy to use graphical Windows interface for setting all parameters in the Integrated Protection System relay. At this time IPScom only supports BECO2200 protocol for communication.
