4.1.4 BMS
Interface
The
E2
series controller may incorporate a BMS network
card equipped with a communication port (Figure 12).
This can be fi eld connected through a serial interface to
a Building Management System via Modbus, BACnet,
SNMP or HTTP protocol as confi gured by the factory. A
controller interfaced to a network must be confi gured for
BMS communication.
BACnet IP, BACnet Ethernet,
HTTP, SNMP, & Modbus IP
BACnet MS/TP
Modbus RTU
