Communication Protocols Buildings - industrial, commercial integrations

ConnectorIO, on August 30, 2023

Below list present integrations, automation solutions and communication protocols possible to integrate with software developed by ConnectorIO.
By design, ConnectorIO solutions are open for extension, modular, multi-protocol, and independent of a specific hardware manufacturer, which is why the integration list will be successively increased.

Supported integrations

ConnectorIO® Agent software can connect devices already installed and available within the building local network. The agent can also handle an assortment that does not conform to the standards. Reasons for expanding and modifying the software may be the age of the equipment, as well as the fact that some modern solutions do not integrate with the equipment of other manufacturers.

Devices or installations that are added later, can be appended to the system by re-running discovery phase (initial commissioning).
After enabling the device in Agent, you can control it functions, visualize its status and create automation rules based on interactions with all other elements of our system.

Systems mentioned below must be reachable by Agent. They do not need to be physically connected to each other in order to use automation features.

Types of connections supported by the agent:

  • network interfaces
  • serial communication
  • radio/wireless communication
  • CAN bus

List of building automation standards

KNX

KNX is open standard for building automation. It is most popular standard for wired installations used in commercial real-estate and households. KNX is based on a two-wire cable.

It is possible to integrate with KNX via IP gateways. While it is also possible to integrate using serial interfaces we recommend IP gateways which are much more reliable.
Common use-cases:

  • “Intelligent” electrical installations
  • Actuators, relays
  • Integration with heating systems

OMS

Open Metering System is european standard for wireless meters covering: gas, oil, water and electricity. It is widely used to track heat costs (via so-called heat cost allocators/dividers).

Common use-cases:

  • “smart” electric meters
  • water meters
  • heat meters
  • heat dividers

ZigBee

ZigBee is a wireless communication protocol. It is used in many areas, but its main purpose is lightweight home automation applications. Sensors based on ZigBee have moderate battery life.

It can be used for many purposes:

  • smart bulbs
  • thermostats
  • valves
  • relays

Modbus

Modbus is a serial communications protocol.

This is common language for industry-wide integrations. Developed in late 70’s – used till today. Despite the evolution of new standards, an undisputed leader in terms of connectivity.

Common use-cases:

  • drivers, process controllers
  • valves, actuators
  • meters and counters
  • industrial equipment

If you are not sure whether your equipment or machine can be integrated, check whether its manufacturer offers an adapter, e.g. for Modbus RTU or Modbus TCP. If it does, then you will be able to integrate it.

M-Bus / Wireless M-Bus

Works in combination with OMS.

Common use-cases:

  • Metering

Z-Wave

Z-Wave is wireless communication protocol. Main advantage of Z-Wave is long battery life.

Common use-cases:

  • Metering
  • Sensors
  • valves, actuators

Siemens S7

S7 controllers are popular PLCs used in automation systems. It can be seen also in building automation.

BACnet

BACnet is communications protocol for Building Automation and Control (BAC) networks. One of most popular protocols in HVAC in continuous development since 90’s.

ConnectorIO supports BACnet/IP as well as serial interfaces with MSTP.

Common use-cases:

  • Air handling units
  • Valves, actuators
  • Process controllers
  • Heating systems

Bluetooth

Bluetooth is a wireless communication protocol. While it is most popular for smart gadgets (watches, phones etc.) it has also its use for automation and home appliances. It is also used to build presence, temperature and climate sensors

DALI

Dali is a common way for digital lighting control. DALI uses two wire bus for communication. It is an early 90’s invention of Phillips, despite its age it is still in use. Multiple revisions of standard available. DALI 2 become an international standard.
