MODBUS BMS INTERFACE

An intelligent interface to Modbus Controllers

FEATURES Activates a BMS event (on a Modbus

device) when an alarm occurs.

Activate an event when a BMS alarmoccurs.

OVERVIEWThe intelligent interface between a Pacom Field Controller and various Modbus

controllers adds another dimension to integrated system management. Modbus is a

protocol developed for use in Building Management Systems (BMS).

The Pacom Field Controller can communicate in Modbus protocol. This enables

bi-directional data to be communicated between the Building Management System

and the Pacom system. The Pacom Field Controller communicates to various Modbus

devices over serial interface by RS 485.

With the Modbus support a BMS event can be activated when an alarm occurs on the

Pacom System. For example, turning the alarm system on/off could activate lighting

and air-conditioning for the appropriate area or oor.

A Pacom event can also be activated when a BMS alarm occurs, for example generating

an alarm when there is a cooling system failure.

In addition to Modbus Pacom also support BACnet, enabling Ethernet communication

between the Pacom Field Controller and the building management system. Please see

separate datasheet for further information concerning the BACnet support.
