The standard for building services

LonWorks® technology is a standardised communication protocol which is well-established in building and industrial automation systems. Properties such as the decentralised intelligence, modular design, requirement-based interfaces and the capability to adjust to existing infrastructures makes LonWorks® an interesting option for the transfer of data in the field layer and for backbone systems.
The individual network participants, the so-called nodes, are able to exchange event-controlled data among themselves.
LonWorks® forms the platform for manufacturer independent communication in multi-service building automation systems.

Typical applications of a LonWorks® infrastructure

  • Heating, ventilation and climate control
  • Light control
  • Shading control
  • Security
  • Energy management, etc.

PCD systems

LonWorks® is available as a communications option for practically all PCD systems. PCD classic controllers are connected to the Saia PG5® COSinus operating system via IP 852 (Ethernet). LON FTT10 is also possible using a communication module, whereby each module supports max. 254 network variables. The PG5 contains a suitable LON resource configurator for configuring the LON nodes and an FBox library for commissioning, testing, transmitting and receiving network variables.

A LON options module is always required for using the LON-over IP (IP 852). A PCD7.R58x is used for memory slots M1 or M2 for PCD3.M5/M6-, PCD2.M5-, PCD1.M2- and PCD1.M0 controllers. The PCD3.R58x module is available for I/O slots.
A “LON communication module” is also required to connect the LON FTT10. This module provides PCD controllers with a LonWorks® interface but without a router function. PCD1.M2 controllers require the PCD2.F2400 module and PCD3 controllers (see supported PCD3 devices in the table belwo) the PCD3.F240 module.
External LON FTT10- / IP gateways are also required to connect FTT10 devices directly to the management system or other LON IP 852 devices, for example. In place of a router, the application program can also copy network variables on IP 852 via PCD resources from any system. 



PG5 LON Configurator and FBox Library

The FBox library can be used for communication control of LON IP (PCD7.R58x) and LON FTT10 (PCD3/2.F240x) modules. The Help describes the functionality of the different FBox modules. Please note that you'll still use the PG5 LON over IP or Lon FTT10 Configurator to create LonWorks node configurations. For detailed information about the work flow, please check out the Saia Lon Manual 26-883.
