112 CNT-SVP01C-EN
nviTemp01 …
nviTemp40
SNVT_temp_p Analog Bind to these 40 network variable inputs to communi-
cate temperatures in degrees Celsius to the device.
The valid range is from –273.17°C to 327.66°C with a
resolution of 0.01°C.
nviUnitStatus01 …
nviUnitStatus20
SNVT_hvac_status Enumerated
Analog
Binary
Bind to this network variable to communicate status
of other control units. The enumerated range is from
0 to 11, which indicates the mode of the controller
(see description of SNVT_hvac_mode in this table).
Analog values have a range of –163.83% to 183.83%.
nviVolts01 …
nviVolts08
SNVT_volt Analog Bind to these eight network variable inputs to com-
municate voltages in volts to the device. The valid
range is from –3,276.8 V to 3,276.8 V with a resolution
of 0.1 V.
nviVolt_f SNVT_volt_f Analog Bind to this network variable input to communicate a
voltage in volts to the device. The valid range of this
floating point value is from –1E38 V to 1E38 V.

Variable name SNVT Data type Description
nviOccSchedule SNVT_tod_event Enumerated Bind to this network variable input to communicate
scheduled occupancy to the device.
nviOccManCmd SNVT_occupancy Enumerated Bind to this network variable input to communicate
occupancy overrides to the device.
nviApplicMode SNVT_hvac_mode Enumerated Bind to this network variable input to communicate
the application mode to the device.
nviValveOverride* SNVT_hvac_overid (Structure) Bind to this network variable input to communicate
water valve overrides to the device.
nviEmergOverride SNVT_hvac_emerg Enumerated Bind to this network variable input to communicate
emergency overrides to the device.
nviDuctStatPress SNVT_press_p Analog Bind to this network variable input to communicate
the duct static pressure in Pascals to the device. The
valid range is from –32,768 Pa to 32,766 Pa with a res-
olution of 1 Pa.
nviDuctStaticSP SNVT_press_p Analog Bind to this network variable input to communicate
the duct static pressure setpoint in Pascals to the
device. The valid range is from –32,768 Pa to
32,766 Pa with a resolution of 1 Pa.
nviDAClSP SNVT_temp_p Analog Bind to this network variable input to communicate
the discharge air cooling setpoint in degrees Celsius
to the device. The valid range is from –273.17°C to
327.66°C with a resolution of 0.01°C.
* The variable nviValveOverride contains structures. This variable cannot be viewed on the operator display.
