SAUTER modulo 6 System Integrated Building Automation M Bus Control Instruction Manual

The modulo 6 system integrates various communication protocols including BACnet, Modbus, M-Bus, MQTT, and RESTful API for seamless connectivity in building automation.
The system can communicate with traditional BACnet networks and IoT devices using MQTT protocol on a secure connection.

The integrated moduWeb Unity web server enables access to BACnet objects and relevant information.

INTRODUCTION

Modulo 6 sets new standards in building automation. SAUTER modulo 6 combines tried and tested building technology with the latest digitalisation trends.

Modern building automation must integrate different data sources and process large amounts of data while at the same time being simple to operate.
It must be possible to plan projects and put them into operation quickly and easily.

The modulo 6 system meets these requirements and integrates seamlessly with the Internet of Things (IoT).
It uses the latest cloud techno-logies while meeting stringent security requirements.

In times of fast-moving technological trends, high availability of system components is expected. Modernisation of existing systems and efficient commissioning without interrupting operations make a significant contribution towards protecting investments.

Everything combined in a stable and safe overall system

Thanks to native support for BACnet, the modulo 6 solution integrates seamlessly into the overall system.

The modular design of the modulo 6 components and the wide range of I/O modules, COM modules, and stations provides maximum flexibility for the realisation of building automation projects.
IoT protocols such as MQTT and RESTful API extend the scope of functions and enable IoT components to be implemented and modulo 6 to be incorporated into IT solutions such as reservation systems, ERP systems and information channels, for example, for weather forecasts.

Selected cybersecurity features:

BACnet Secure Connect

On-board firewall
Network separation IT/OT

Protected access to the web server

Integration from the field level to the IoT and cloud

modulo 6 integrates all communication protocols for heating, ventilation, air conditioning, lighting, blinds, and energy. The open communication standard BACnet (Building Automation Control Network) is the backbone of SAUTER building automation and the interface that our automation stations use to communicate. All modulo 6 automation stations are BTL-certified and ensure interoperability and compatibility with other BACnet devices.

Plugin modules for extending the modulo 6 automation stations support the Modbus and M-Bus communication protocols. Systems such as chillers and air conditioning units can be connected using Modbus.

The M-Bus module for reading electrical and heat meters provides data for energy optimisation and billing.

modulo 6 brings together heating, ventilation and air conditioning into a single system. The analysis of operating and usage data in the cloud allows continuous optimisation and forms the basis for sustainable economic operation. The automation station can optionally communicate simultaneously with the traditional BACnet building network and with IoT devices using the MQTT proto-col on a secure, encrypted connection.

RESTful API
The integrated moduWeb Unity web server is parti-cularly suited to small and medium-sized installations. In addition, a standard RESTful API can be en-ab-led so that gateway functionality is also possible.The API allows access to BACnet objects and vari-ous BACnet-relevant information of the automation station.

Operation options

Local operating interface LOI
The universal local LOI, featuring a high-resolution graphic colour display, allows for both viewing and operation. The LOI for priority operation (as per ISO 16484-2) is plugged into an I/O module and immediately shows all the relevant data of the module in real time. The compact device is operated using 4 buttons. The I/O signals are displayed graphically and numerically. The small display can also map and show the course of analogue and digital signals over time.

Security by Design

Integrating IoT devices and intelligent systems makes modern building automation systems more efficient, but also more vulnerable to cyber attacks. In line with the Defence in Depth security concept, SAUTER incorporates multiple security solutions to protect your building automation from threats.
Defence in Depth ensures that security measures are implemented at different levels, such as network, soft-ware, hardware and physical access. This minimises the risk of security breaches and ensures the protec-tion of sensitive data and systems that are essential to the operation and security of buildings.

BACnet Secure Connect (BACnet/SC)

BACnet Secure Connect, the new BACnet connec-tion, is based on TLS 1.3 and allows an encrypted communication between devices. Customers get a private building automation network where they can control certificate issuance and access, or hand it over to SAUTER. BACnet/SC is ideal for enterprise IT. Seamless integration into the existing infrastructure is facilitated by the SAUTER modu630-RT BACnet router.

BACnet/SC scenario: Headquarters for building management of multiple properties with BACnet/IP SAUTER Vision Center can take on the role of the primary hub. This is the central element of the network and configures and controls the communication of the encrypted BACnet objects. The modu630-RT BACnet router can be used both as a BACnet/SC primary hub and as a BACnet/SC failover hub.

Safety measures related to IEC 62443

This international standard, focused on cybersecurity for industrial automation and control systems (IACS), provides guidelines for securing systems by addressing both technical and process-related risks. The standard emphasizes a risk-based approach. It categorises security levels based on potential threats and defines requirements for secure product development and integration. The standard is in line with various official directives, such as the EU General Data Protection Regulation (GDPR), the NIS and NIS-2 guidelines, the Cyber Resilience Act (CRA), the UK‘s PSTI and the Swiss Data Protection Act, to name a few.

Network access control (NAC)

The NAC functionality, according to IEEE 802.1X / RADIUS requires authentication of devices and users to ensure that only authorised entities have access to network resources. It also ensures the traceability of device and user actions for complete monitoring and control.

moduWeb Unity, the embedded web visualisation
The integrated web server functionality allows for installation, system visualisation, operation and optimisation as well as remote access to all administrative tasks from any location, in accordance with building technical standards. Intuitive, flexible and budget-friendly.

The moduWeb Unity graphical user interface makes it possible to display and operate entire buildings, zones, individual rooms and technical systems.
The structured representation of BACnet objects and a self-explanatory graphical calendar, time programmes, and trend logs allow building technicians to carry out their daily tasks easily and efficiently.
The functions contribute to compliance with the factors pro-posed in EN 52120 regarding building automation and control systems (BACS).
As a BACnet client, moduWeb Unity can query and display BACnet objects from other stations. This pro-vides a local building management solution for small and medium-sized installations.
