Communication options

Devices with Mervis Runtime are able to communicate with other devices. The different communication ways use different hardware communication channels, and different communication protocols. Some protocols are only able to run on certain communication channels.

  • Channel types: serial line (COM port), Ethernet based channels like TCP, UDP etc.
  • Communication protocols: Modbus, M-bus, BACnet etc.

Most protocols support two different communication roles:

  • Server (or slave)
  • Client (or master)

The availability of communication channels and protocols depends on the hardware platform used. The communication protocols are added continuously. However, some of the simple protocols may be implemented on a customer basis in the ST language.

Tomdefine communication with particular devices, it is possible to create templates, or communication maps. The maps may be exported.
