Tracer MP503 bindings
CNT-SVX09B-EN 17
Sending data
A network variable output (nvo) sends data to other devices on the Lon-
Talk network. The network variable outputs (including their SNVTs) that
are commonly used in Tracer MP503 bindings are shown in Table 2.

Variable name Data type Description
nvoTemperature1 SNVT_temp_p Universal input 1 sta-
tus output
Indicates the value of universal input 1 if it is
configured as thermistor.
If universal input 1 is not configured as ther-
mistor, this output is invalid.
nvoTemperature2 SNVT_temp_p Universal input 2 sta-
tus output
Indicates the value of universal input 2 if it is
configured as thermistor.
If universal input 2 is not configured as ther-
mistor, this output is invalid.
nvoTemperature3 SNVT_temp_p Universal input 3 sta-
tus output
Indicates the value of universal input 3 if it is
configured as thermistor.
If universal input 3 is not configured as ther-
mistor, this output is invalid.
nvoTemperature4 SNVT_temp_p Universal input 4 sta-
tus output
Indicates the value of universal input 4 if it is
configured as thermistor.
If universal input 4 is not configured as ther-
mistor, this output is invalid.
nvoBIP1Status SNVT_switch Universal input 1 sta-
tus output
Indicates the value of universal input 1 if it is
configured as binary.
If universal input 1 is not configured as
binary, this output is invalid.
nvoBIP2Status SNVT_switch Universal input 2 sta-
tus output
Indicates the value of universal input 2 if it is
configured as binary.
If universal input 2 is not configured as
binary, this output is invalid.
nvoBIP3Status SNVT_switch Universal input 3 sta-
tus output
Indicates the value of universal input 3 if it is
configured as binary.
If universal input 3 is not configured as
binary, this output is invalid.
nvoBIP4Status SNVT_switch Universal input 4 sta-
tus output
Indicates the value of universal input 4 if it is
configured as binary.
If universal input 4 is not configured as
binary, this output is invalid.
nvoCurrent1 SNVT_amp_mil Universal input 1 sta-
tus output
Indicates the value of universal input 1 if it is
configured as 0–20 mA.
If universal input 1 is not configured as 0–20
mA, this output is -3276.8.
nvoCurrent2 SNVT_amp_mil Universal input 2 sta-
tus output
Indicates the value of universal input 2 if it is
configured as 0–20 mA.
If universal input 2 is not configured as 0–20
mA, this output is -3276.8.
