Tracer MP503 bindings
The principal purposes of a Tracer MP503 I/O module are to gather data
(sensor readings) for use by a BAS or peer device and to allow a BAS or
peer device to control Tracer MP503 binary outputs. Therefore, the use of
bindings is very important in Tracer MP503 applications.
The examples in this chapter illustrate some common applications in
which bindings are used with the Tracer MP503.
Receiving data
A network variable input (nvi) receives data from other devices on the
LonTalk network. Network variable inputs (including their SNVTs) that
are commonly used in Tracer MP503 bindings are shown in Table 1.
