METZ CONNECT & MBS:
Open I/O modules for more systems
Automatically detect. Integrate directly into BACnet, MQTT, and KNX.
Many I/O modules communicate reliably via Modbus. However, as soon as their data needs to be integrated into other automation and management systems, manual engineering often becomes necessary.
Together, METZ CONNECT and MBS have largely automated this process.
The Challenge
I/O modules serve as the link between sensors, actuators, and higher-level automation systems.
However, integrating them into different system environments often requires:
Manual Device Assignment
Custom Data Mapping
Additional configuration work
Detailed knowledge of data structures
Recurring Engineering Effort
This takes time and increases the likelihood of errors, especially with larger systems or when using different types of modules.
The Solution
METZ CONNECT offers a versatile family of Modbus-based I/O modules.
MBS has integrated the device information for the individual module types into the universal firmware of its gateways. When a scan of the Modbus bus is initiated via the web interface, the gateway automatically detects which of the supported modules is connected.
The appropriate data model is assigned immediately. The Modbus data can then be made available in BACnet, MQTT, or KNX.
The configuration can then be completed in just a few steps.
The result
Automatic detection of supported I/O modules
Automated Assignment of Data Points
Less manual configuration effort
Faster commissioning
Simplified Maintenance and Analysis
Integration with BACnet, MQTT, and KNX
Expanded Applications for Existing Modbus Modules
Other communication protocols, such as PROFINET, are planned.
Typical areas of application

Modernization of Existing Facilities
PLC Connections
Cross-Vendor Automation Solutions
More protocols. Less engineering.
The combination of METZ CONNECT I/O modules and the MBS Universal Gateway brings together proven field technology with open communication standards.
Instead of mapping each module individually, the gateway detects the type of connected device and automatically applies the appropriate mapping. This reduces the effort required for project planning, commissioning, and maintenance.
This allows existing Modbus modules to be integrated into additional system environments—without having to rebuild the field level.
Achieving More Together
METZ CONNECT brings its expertise in the development of reliable I/O modules and electronic components for building automation.
MBS complements this expertise with gateway technology, universal firmware, and decades of experience in integrating various communication protocols.
Together, we create a seamless solution from the field level all the way up to the control system or PLC.
Open to more systems.
And for applications that go beyond traditional building automation.

Frequently Asked Questions
Which METZ CONNECT modules are automatically detected?
The solution currently supports 19 different I/O module types from the METZ CONNECT Modbus family. The MBS gateway uses the communication on the Modbus bus to determine which supported device type is connected.
How does automatic data mapping work?
For supported modules, the relevant device and data point information is stored in the MBS gateway’s universal firmware. Once a device is detected, the appropriate data model is automatically loaded and assigned to the module’s data points.
Which communication protocols are supported?
Data from METZ CONNECT modules can currently be transmitted via BACnet, MQTT, and KNX. Support for additional protocols, such as PROFINET, is planned.
Is manual configuration still required?
Device detection and basic mapping occur automatically. Project-specific settings can then be configured via the MBS gateway's web interface.
What are the benefits of automatic device detection?
It reduces the amount of manual engineering work, shortens commissioning time, and lowers the risk of incorrect data point mappings. At the same time, maintenance is simplified because the device type and data structure are clearly defined.
Can the solution also be used outside of building automation?
Yes. This combination is suitable for any application where Modbus I/O modules need to be connected to supervisory control systems, PLCs, or other automation platforms. This also includes applications in mechanical and plant engineering.
