SOFTWARE DESCRIPTION

The Node Object monitors and controls the functions of the
different objects in the device. It supports the basic functions
Object-Status and Object-Request required by LonMark.
Refer to Fig. 7 for a basic illustration of Node Objects. The
following objects are monitored by the Node Object.

nvoLow switch over when the hysteresis is expired (factory
setting 2 Kelvin).5; 1. counted measurand = 1.
Temp_1- 8 Objects

nvoTemp_1...8
The output variable supplies a value with format ° C
depending on the input signal of 0 to 10.0 V and the settings in
UCPTTempHigh and UCPTTempLow and/or the resistance of
the selected temperature sensor.
nvoTemp_1...8
See Temp_1...8 but with 0.01° C format.
nvoPercent_1...8
The output variable supplies a value with format 0 to 100.0%
for voltage measurements depending on the input signal of 0
to 10.0 Volt.
nvoVoltage_1...8
The output variable supplies a value with format 0 to 10.0 Volt
for voltage measurements depending on the input voltage.
nvoResistance_1...8
The output variable supplies a value with format Ohm
depending on the input signal of 40 Ohm to 4 MOhm.
