APPLICATION GUIDEOVERVIEW
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.
