Easy Integration of Danfoss System Managers with BMS & PLC Systems
Export live data from the AK-SM 800 series to third-party systems via Modbus TCP and BACnet/IP.
SM8X2M1 is a protocol converter that enables data to be read from and written to Danfoss AK-SM 800/800A and AK-SC 255/355 systems from supervisory systems such as PLC, BMS and SCADA – without the need to develop a custom XML driver.
The Challenge
Danfoss System Managers use an XML-based interface for external communication.
For third-party systems, this means:
- Time-consuming development of custom XML drivers
- Increased project complexity
- Higher integration costs
- More difficult servicing and troubleshooting
For many BMS and PLC integrators, this creates an unnecessary technical barrier.
The Solution
SM8X2M1 translates the communication into standard protocols already supported by most control systems.
The unit:
- Exports live data from the AK-SM 800 series
- Enables both reading and writing of parameters
- Supports both Modbus TCP and BACnet/IP
- Maintains access to the AK-SM via WAN
The result is a direct, reliable and future-ready integration without custom development.

Business Benefits
Reduced Project Time
No development of custom XML drivers is required.
Standard protocols such as Modbus TCP and BACnet/IP enable direct integration into existing BMS environments.
Result: Shorter project lead times and lower engineering costs.
Lower Integration Risk
XML integration is project-specific and can be sensitive to version changes.
SM8X2M1 provides structured data through established industrial protocols.
Result: Fewer commissioning issues and easier troubleshooting.
Reusable Solution
The same integration approach can be used across multiple projects, regardless of customer or facility.
Result: Standardization improves efficiency and project margins.
Support & Remote Access
Technical Support
We provide technical support for:
- Network configuration
- Protocol mapping (Modbus TCP / BACnet/IP)
- Commissioning and troubleshooting
You get access to technicians with in-depth knowledge of both Danfoss System Managers and integration environments.
Secure Remote Access
Using the advanced networking capabilities of the RUTM08 platform, we can – when required and by agreement – remotely connect to the unit to:
- Check the configuration
- Adjust network settings
- Update software
- Troubleshoot communication in real time
- Verify data flows to PLC/BMS systems
This minimizes the need for on-site visits and reduces downtime.
The platform supports VPN and secure remote connectivity.
