Use
The DP/LON link facilitates the direct exchange of data between the PROFIBUS-DP
(Decentralised Peripherals) and the LON (Local Operating Network).
The LON devices are integrated with the PROFIBUS DP by connecting the two open
standard communications systems – the PROFIBUS DP for the SIMATIC S7 and the
LON bus for the building automation system.
The DP/LON link is particularly suitable for individual room control functions. Multi-
disciplinary applications such as the operation of lighting, blinds and individual room
controllers from a single room unit are easy to implement. The electrical plant, solar
protection and individual room control disciplines can all be monitored, controlled and
displayed in the uniformly engineered SICLIMAT X building management system.
The DP/LON link has a compact housing, insulated to protection standard IP40. It is
constructed for installation in the field, in control panels and on sub-distribution boards.
The unit is mounted on a standard DIN rail.
It is connected as a DP slave to the SIMATIC S7. Data can be exchanged by over the
LON in a polling process; no engineering is required. There is no need for LON network
variable bindings to the communications interface.
The SICLIMAT Engineering Manager EM incorporates the most common DESIGO RX
applications in the form of "Standard Typicals".
