APPLICATION GUIDE

OVERVIEW

The

Simplicity

LINC Gateway operates as a Modbus® Client

providing an interface between a BACnet® MS/TP control system
and devices that communicate using the Modbus RTU protocol.
The

Simplicity

LINC allows monitoring and control by a third-party

BACnet Building Automation System (BAS).

The

Simplicity

LINC is preconfigured to provide an interface to UP

products equipped with

Simplicity

controllers manufactured after

4/2/2008 as well as prior

Simplicity

Elite™ and

Simplicity

with

Intelli-Comfort™ controllers.

The

Simplicity

LINC mounts inside the control panel of the UP

unit and utilizes 24 VAC power from the unit’s control transformer.
One port is connected to the UP controller. The other port must be
connected to the BACnet MS/TP network.

The

Simplicity

LINC Gateway is preconfigured to obtain

operational data points from the controller and expose them on a
BACnet MS/TP network.

NOTE:

Not all

Simplicity

operating parameters are controlled/

monitored by the

Simplicity

LINC.
