A united BMS interface with S‑Link


Introducing a unified BMS interface, compatible with Modbus, BACnet, and KNX protocols. PAW-AC2-BMS-16, 64, 128.
BMS interface with Panasonic communication bus helps you to get significant savings.
Easy to use and reliable interfaces for a straightforward integration.


Direct connection to S-Link communication bus

One interface for all three protocols!*

The interface can provide faster, cheaper, easier solution in your projects!
· No need for additional gateway (CZ-CFUNC2)
· Significant 50% cost saving for BMS interface*
· Avoid mistakes and reduce configuration time.

* In the case of PAW-AC2-BMS-16 by Panasonic calculation. ** One BMS protocol is available per one interface.


System example with the unified BMS interface.

* U1U2 link is connected directly to IntesisBox. Support from 16 to 128 per each interface.

Easy configuration

· A single device supporting all Modbus, BACnet, and KNX protocols
· Dedicated configuration support tool (MAPs for Panasonic)
· Firmware updates with improvements and features
· Scan: Automatic identification of the units present in the VRF system

Screen examples of MAPs for Panasonic.

Upgraded specifications

· Electricity consumption calculation using three inputs from pulse meters or Modbus meters
· BACnet: Version 14 and BTL Certified
· Modbus and BACnet 128 units now supports IP and RTU/MSTP
