Touch-Plate Mystique BACnet smart control station MYS-B (BACnet MS/TP) BACnet points list
Updated 12 November 2026
The Mystique MYS-B is an 8-button wall control station that is its own BACnet MS/TP device. Each button shows up twice, as a toggling input and as a press/release input, and each button LED can be switched or given a color/flash mode from the BMS; the list shows the button 1 objects of each range. An Input Change Buffer object lets a front end catch presses without COV.
This page lists 9 BACnet objects for the Touch-Plate Mystique BACnet smart control station MYS-B (BACnet MS/TP) — 6 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Touch-Plate’s own free documentation, linked below.

BMS integration notes: Touch-Plate Mystique BACnet smart control station MYS-B (BACnet MS/TP)
Subscribe COV on the button inputs, or poll AV 1001 Input Change Buffer if the front end can't do COV. Use the maintained inputs (BI 101-108) for press-and-hold logic and the momentary ones (BI 1-8) for toggles. Drive the button LEDs from the BMS through BO 1-8 or AV 1-8 to show load status.
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 |
|---|---|---|---|
| BI 1 | Momentary01 | Button 1 toggle; BI 2-8 for the other buttons | Read |
| BI 101 | Maintained01 | Button 1 held = 1; BI 102-108 for the others | Read |
| AV 1001 | Input Change Buffer | Last press 1-8, release 1001-1008 | Read |
| BO 1 | LED Controls | LED 1 on/off; BO 2-8 for the other LEDs | Command |
Network setup
- Device instance is factory set in 68501-68999 (on a label) and can be changed through AV 1003.
- MS/TP MAC address is set with DIP switches or AV 1004; baud 9600, 19200, 38400 or 76800 by DIP switch or AV 1002.
- Changing the baud rate takes effect after a power cycle; changing the MAC address resets the unit.
- The manual recommends 10 or fewer stations per MS/TP trunk and keeping lighting on its own trunk.
Watch out for
- COV subscriptions expire by default; write 1 to AV 100 to allow a lifetime of 0 (never expire).
- Momentary inputs flip state on every press and start at 0 after power-up; they don't follow the button.
- LED intensity is common to all LEDs: the last intensity written applies to every LED.
Touch-Plate Mystique BACnet smart control station MYS-B (BACnet MS/TP) BACnet objects
Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.
Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.
| Description | States | |||||
|---|---|---|---|---|---|---|
| BImin | 1 | Momentary01 | Button 1, toggles on each press (BI 1-8 = buttons 1-8) | Read | 0=Off, 1=On | |
| BImin | 101 | Maintained01 | Button 1, 1 while held (BI 101-108 = buttons 1-8) | Read | 0=Off (released), 1=On (pressed) | |

Object ID lookup: Touch-Plate Mystique MYS-B point IDs by name
Integration notes
- Per-button objects are printed as ranges with a name pattern: BI 1-8 "Momentary0#", BI 101-108 "Maintained0#", AV 1-8 "Pilot0#" (# = button or LED 1-8), and BO 1-8 for the LEDs. Only the button/LED 1 object of each range is listed; add the button number for the others.
- The manual prints no object name for the LED BOs; the table label "LED Controls" is used.
- The Ultra ULT-B manual has the same table with 6 buttons (BI 1-6, BI 101-106, BO 1-6, AV 1-6) and the same AV 100 and AV 1001-1004.
- There is no read/write column. Access is inferred from the object descriptions; AV 1-8 have a priority array.
- LED mode codes (color, flash, intensity) are in the manual's appendix; intensity is shared by all LEDs.
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 Mystique BACnet smart control station MYS-B (BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the Touch-Plate Mystique BACnet smart control station MYS-B (BACnet MS/TP)
How many BACnet points does the Touch-Plate Mystique BACnet smart control station MYS-B (BACnet MS/TP) have?
This list has 9 BACnet objects: 6 analog values, 2 binary inputs, 1 binary output. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Touch-Plate Mystique BACnet smart control station MYS-B (BACnet MS/TP) BACnet points are writable?
6 of the 9 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. The source has no read/write column, so this is inferred from object type.
Where is the official Touch-Plate Mystique BACnet smart control station MYS-B (BACnet MS/TP) BACnet documentation?
The source is Mystique BACnet Manual, published free by Touch-Plate at https://touchplate.com/wp-content/uploads/product-documents/Stations/BACnet-Mystique/Mystique-BACnet-Manual-Digital.pdf.
What are the minimum BACnet points to integrate the Touch-Plate Mystique BACnet smart control station MYS-B (BACnet MS/TP)?
Start with BI 1 Momentary01 (Button 1 toggle; BI 2-8 for the other buttons); BI 101 Maintained01 (Button 1 held = 1; BI 102-108 for the others); AV 1001 Input Change Buffer (Last press 1-8, release 1001-1008); BO 1 LED Controls (LED 1 on/off; BO 2-8 for the other LEDs).
How do I check these points on the real Mystique BACnet smart control station MYS-B (BACnet MS/TP)?
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.
