Data Sharing—LonWorks
Tracer ZN524 allows peer-to-peer data
communication through the use of
LonWork’s technology. Data such as
space temperature setpoint, occupancy,
etc. can be shared from a master con-
troller to a peer controller over a twist-
ed pair of communication wire with or
without the presence of a front end
building management system. (See
Figure 16: “Simple data sharing appli-
cation”) This ability allows units to
operate with the same data to prevent
conflicting control.
Data sharing is established through the
use of “bindings”. Bindings are set up
through the Rover service tool.
The Tracer ZN524 controller includes a
network variable for master/slave oper-
ation. This variable includes all of the
information required for the slave units
to operate with master controller. (See
Figure 17: “More complex data sharing
application”)
For more information on establishing
bindings, see the Rover service tool
manual. For a complete listing on
shared points see
“Appendix—Data
Lists” on page 47.
