BMS integration notes: Functional Devices RIBMNW24B-44-BC 4-input / 4-relay module
Command BO1-BO4 and read BI1-BI4; there is no on-board logic.
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 1 command | Command |
| BO 2 | BO2 | Relay 2 command | Command |
| BO 3 | BO3 | Relay 3 command | Command |
| BO 4 | BO4 | Relay 4 command | Command |
| BI 1 | BI1 | Input 1 status | Read |
| BI 2 | BI2 | Input 2 status | Read |
| BI 3 | BI3 | Input 3 status | Read |
| BI 4 | BI4 | Input 4 status | Read |
Network setup
- The PICS prints the device object ID default as DEV277000 (vendor ID 277); it is writable.
- MS/TP master; baud rates are listed in the PICS. Max_Master defaults to 127.

Object ID lookup: Functional Devices RIBMNW24B-44-BC 4-input / 4-relay module 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...). Names are limited to 4 characters.
- Binary input text defaults to OFF/ON (up to 4 characters, writable); polarity can be reversed.
- The PICS header prints the model as "RIBMW24B-44-BC" and Model_Name as "RIBMW24B-44BC".
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 RIBMNW24B-44-BC 4-input / 4-relay module and exports what it actually has to Excel — free.

Questions about the Functional Devices RIBMNW24B-44-BC 4-input / 4-relay module
How many BACnet points does the Functional Devices RIBMNW24B-44-BC 4-input / 4-relay module have?
This list has 8 BACnet objects: 4 binary inputs, 4 binary outputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Functional Devices RIBMNW24B-44-BC 4-input / 4-relay module BACnet points are writable?
4 of the 8 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 RIBMNW24B-44-BC 4-input / 4-relay module BACnet documentation?
The source is RIBMNW24B-44-BC PICS v1.09, revision 2016-06-24, published free by Functional Devices at https://www.functionaldevices.com/sfsites/c/cms/delivery/media/MCZDKKPSSA6VF6NJCMKY5U7KKKC4.
What are the minimum BACnet points to integrate the Functional Devices RIBMNW24B-44-BC 4-input / 4-relay module?
Start with BO 1 BO1 (Relay 1 command); BO 2 BO2 (Relay 2 command); BO 3 BO3 (Relay 3 command); BO 4 BO4 (Relay 4 command); BI 1 BI1 (Input 1 status); BI 2 BI2 (Input 2 status); BI 3 BI3 (Input 3 status); BI 4 BI4 (Input 4 status).
How do I check these points on the real RIBMNW24B-44-BC 4-input / 4-relay module?
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.
