Functional Devices RIBTWX240xB-BC / RIBMNWX240xB-BC BACnet relay (1 relay, 2 inputs) BACnet points list
Updated 12 November 2026
A BACnet MS/TP relay with one relay (BO1) and two binary inputs (BI1, BI2). All three objects are plain I/O with user-writable names; there is no on-board control logic.
This page lists 3 BACnet objects for the Functional Devices RIBTWX240xB-BC / RIBMNWX240xB-BC BACnet relay (1 relay, 2 inputs) — 1 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Functional Devices’s own free documentation, linked below.

BMS integration notes: Functional Devices RIBTWX240xB-BC / RIBMNWX240xB-BC BACnet relay (1 relay, 2 inputs)
Write BO1 to switch the relay and read BI1 and BI2 for the inputs.
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.
| Object | Name | Why | Access |
|---|---|---|---|
| BO 1 | BO1 | Relay command | Command |
| BI 1 | BI1 | Binary input 1 status | Read |
| BI 2 | BI2 | Binary input 2 status | Read |
Network setup
- The PICS prints the device object ID default as DE277000 (vendor ID 277); it is writable.
- MS/TP master; the PICS lists 9600-115200 baud. Max_Master defaults to 127.

Object ID lookup: Functional Devices RIBTWX240xB-BC / RIBMNWX240xB-BC BACnet relay point IDs by name
Integration notes
- Object names are user-writable and the PICS prints no factory default name, so each object is listed by its printed ID (BI1, BO1...).
- BO1 has a 16-level priority array and writable minimum on / off times (0-65535 s); polarity and active / inactive texts are writable on every object.
- The PICS lists AnalogInput among the supported object types, but the object list has only BI1, BI2 and BO1.
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 RIBTWX240xB-BC / RIBMNWX240xB-BC BACnet relay (1 relay, 2 inputs) and exports what it actually has to Excel — free.

Questions about the Functional Devices RIBTWX240xB-BC / RIBMNWX240xB-BC BACnet relay (1 relay, 2 inputs)
How many BACnet points does the Functional Devices RIBTWX240xB-BC / RIBMNWX240xB-BC BACnet relay (1 relay, 2 inputs) have?
This list has 3 BACnet objects: 2 binary inputs, 1 binary output. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Functional Devices RIBTWX240xB-BC / RIBMNWX240xB-BC BACnet relay (1 relay, 2 inputs) BACnet points are writable?
1 of the 3 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 Functional Devices RIBTWX240xB-BC / RIBMNWX240xB-BC BACnet relay (1 relay, 2 inputs) BACnet documentation?
The source is RIBxW240xB-BC PICS v1.1, revision 2016-06-24, published free by Functional Devices at https://www.functionaldevices.com/sfsites/c/cms/delivery/media/MCAB425QWSPFEJ5NM76IFS54YAME.
What are the minimum BACnet points to integrate the Functional Devices RIBTWX240xB-BC / RIBMNWX240xB-BC BACnet relay (1 relay, 2 inputs)?
Start with BO 1 BO1 (Relay command); BI 1 BI1 (Binary input 1 status); BI 2 BI2 (Binary input 2 status).
How do I check these points on the real RIBTWX240xB-BC / RIBMNWX240xB-BC BACnet relay (1 relay, 2 inputs)?
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.
