4.1.4 BMS
Interface
The
E2
series controller may incorporate a BMS network
card with a communication port (Figure 10). This can be
fi eld connected through a RS-485 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.
