LINC GATEWAY
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
BACnet Building Automation System (BAS).
The Simplicity
products equipped with Simplicity
4/2/2008 as well as prior Simplicity®Elite™ and Simplicity® with
Intelli-Comfort™ controllers.
®
LINC allows monitoring and control by a thi rd-party
®
LINC is preconfigured to provide an interface to UP
®
controllers manufactured after
®
The Simplicity
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
LINC mounts inside the control panel of the UP
®
operating parameters are controlled/
monitored by the Simplicity
®
LINC.

CONNECTION
The Simplicity®LINC has 2 ports, one for connection to the BAS
network (BACnet) and one to the Simplicity® board (Modbus).
BACNET NETWORK
The only connection required in the field is to the BACnet (BAS)
network.
NOTE: Proper termination and grounding of the shields must
be observed.
DIP switches A0-A7 on the Simplicity
selection of the MAC Address. The MAC Address identifies the
Simplicity
99. The default DIP switch setting is 1.
A Device Instance (DE) Modifier is used by the Simplicity
and defaulted to 230. The combination of the DE Modifier and
the default DIP switch setting creates a default DE of 23001.
The default Unit Name is YORK_RTU.

MODBUS CONNECTION
The UP device communicates with the Simplicity
the Modbus RTU protocol on an RS485 connection. Connection
and addressing of the UP product is completed at the factory.
No further adjustment should be done.
The default Simplicity® board address is 1. Do not
engage the Address button on the Simplicity® board.
This changes the address and causes a Modbus
communication failure.
®
If a problem arises with the Simplicity
exposed by the Simplicity®LINC requires modification, the U P
controller software can be manipulated using a Microsoft©
Windows-based PC with the Simplicity
(downloadable from the UP website). To connect the PC to the
UP controller, a FREEnet USB adaptor (Part No.
S103101967000), which is an RS232 to RS485 adapter, and
FREEnet adapter cable (S102538682000) are required and
available through SOURCE1 (Toll-free at 1-800-536-6112).

SOFTWARE SETUP
The control sequence is managed by the Simplicity® controller.
The data points on these systems are mapped to standard AV
and BV BACnet Objects. As a preconfigured application, no
configuration is necessary in the Simplicity
®
LINC Gateway.
DIP switches B0-B3 on the Simplicity®LINC board allow for
selection of the BACnet transfer speed.The default speed is set
at 38.4k baud. Other speeds can be chosen as shown in Table
1.

FLASH MEMORY MANAGEMENT
®
The Flash Memory chip used in the Simplicity
controllers has
a 1,000,000 write cycle rating.
To prevent premature failure of the flash memory, it should not
be written to more often than once every 10 minutes, on
average.
Under unusual circumstances it could take up to two
minutes for newly updated data to be seen.
ADDITIONAL CAPABILITY
MODBUS COMMUNICATION ALARM
One digital point is available to indicate communication
problems between the Simplicity
BI 84 (MODBUS_ALARM) is used to indicate Modbus
communication problems between the Simplicity
Gateway and the UP controller. When "on" this point indicates
loss of Modbus communication. The last data received from the
UP controller remains in the Simplicity
function as if communications were normal.
NOTE: The MODBUS ALARM (BI84) is the only method to
verify communication between the Simplicity
UP controller.
