Johnson Controls Simplicity LINC Gateway (YORK / JCI Unitary Products rooftops) BACnet points list

Updated 12 November 2026Unofficial source

Short answer

The Simplicity LINC is a small gateway mounted in the rooftop unit's control panel. It polls the Simplicity unit controller over Modbus RTU and exposes a fixed set of points on BACnet MS/TP; no configuration is needed. The map has 34 analog inputs, 58 analog values (setpoints, sensor values and settings), 65 binary inputs (outputs, safeties, alarms) and 40 binary values (option and mode enables, comm-value selects, redline/loadshed).

This page lists 197 BACnet objects for the Johnson Controls Simplicity LINC Gateway (YORK / JCI Unitary Products rooftops) — 98 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Johnson Controls’s documentation hosted by Distributor web store (Shopify CDN), not by Johnson Controls itself, so treat it as unofficial.

BMS integration notes: Johnson Controls Simplicity LINC Gateway (YORK / JCI Unitary Products rooftops)

Integration in brief

Set the MAC address (1-99) on DIP switches A0-A7 and the baud on B0-B3 (default 38400); the device instance combines the DE modifier 230 with the MAC (default 23001). The BAS writes the occupied/unoccupied cooling and heating setpoints and can supply space temperature, outdoor temperature, humidity and IAQ values once the matching COMM_ accept BV is set. Read supply air temperature, the active alarm and the alarm buffers.

Minimum points to map

The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Integration notes

Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the Simplicity LINC Gateway (YORK / JCI Unitary Products rooftops) and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.

Questions about the Johnson Controls Simplicity LINC Gateway (YORK / JCI Unitary Products rooftops)

How many BACnet points does the Johnson Controls Simplicity LINC Gateway (YORK / JCI Unitary Products rooftops) have?

This list has 197 BACnet objects: 34 analog inputs, 58 analog values, 65 binary inputs, 40 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Johnson Controls Simplicity LINC Gateway (YORK / JCI Unitary Products rooftops) BACnet points are writable?

98 of the 197 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done.

Where is the official Johnson Controls Simplicity LINC Gateway (YORK / JCI Unitary Products rooftops) BACnet documentation?

Johnson Controls does not publish it on its own website. This list comes from Simplicity LINC Gateway Application Guide (ConFig v1.01d) (1031990-UAD-A-0313), revision 2013-03, a copy hosted by Distributor web store (Shopify CDN) at https://cdn.shopify.com/s/files/1/2139/8037/files/Johnson_Controls_Simplicity_LINC_GATEWAY_ee98fa51-0864-41dc-924a-3e68ee281f71.pdf?788. Ask Johnson Controls or its representative for the current revision.

What are the minimum BACnet points to integrate the Johnson Controls Simplicity LINC Gateway (YORK / JCI Unitary Products rooftops)?

Start with AV 1 OCC_COOL_SP (Occupied cooling setpoint, 46-99 °F); AV 50 OCC_HEAT_SP (Occupied heating setpoint, 45-98 °F); BI 16 AIR_PROOF_SW (Air proving switch (1 = air flow)); AI 4 SUP_AIR_TEMP (Supply air temperature); AV 6 SPACE_TEMP (Space temperature (BAS can write it)); AI 15 ACTIVE_ALARM (Active alarm); BI 11 MODBUS_ALARM (Gateway lost Modbus link to the unit).

Can the BMS supply sensor values to the Johnson Controls Simplicity LINC Gateway (YORK / JCI Unitary Products rooftops)?

AV 6 SPACE_TEMP, AV 7 AMB_TEMP, AV 10 AMB_AIR_HUM, AV 12 RET_AIR_HUM and AV 8 IAQ_VALUE are writable; set BV 108 COMM_ST, BV 101 COMM_OAT, BV 100 COMM_OH, BV 99 COMM_RH or BV 109 COMM_IAQ so the controller accepts the BAS value.

How do I check these points on the real Simplicity LINC Gateway (YORK / JCI Unitary Products rooftops)?

Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
