The Difference between Fahrenheit / Celsius
Although initially defined by the freezing point of water (and later melting point of ice), the Celsius scale is officially derived among Kelvin
scale: Zero on the Celsius scale (0 ° C) corresponds to 273.15 K, with a temperature difference of 1 ° C which is equivalent to a
difference of 1° K - the size of the unit in each scale is the similar. Therefore 100 ° C, the previously defined boiling point of water,
equates to 373.15K. Due to the fact the Celsius scale is an interval system, but not a ratio system, means it follows a relative and not an
absolute scale.
This is indicated by the fact that a temperature interval between 20 ° C and 30 ° C is the same as between 30 ° C and 40 ° C, but
essentially 40 ° C does not have twice the air heat energy like 20 ° C. A temperature difference of 1 ° C therefore corresponds to a
temperature difference of 1.8 ° F.
There both scales are used worldwide, it is important to know in advance which measurement scale to use for configuration.
Note
The CS141 recalculates the values when rescaling the scale and adjusts the settings automatically - but a higher-level system
configured to Fahrenheit will inevitably receive incorrect information from a web manager set to Celsius.
This small problem may lead into a big impact, especially if teams are placed inside an international co-operation.
As an example, on December 12, 1998, the Mars Climate Orbiter has entered as programmed the mars orbit, but 170 kilometers lower
than planned. Investigations found the reason for this incident: There was a communication issue between two different groups of NASA
scientists who performed the trajectory calculations - one used inches and the other meters. They simply forgot to communicate this
small fact…:
„The „root cause “… was the failed translation of English units into metric units in a segment of ground-based, navigation-related
mission software … “
Provided services
For this configuration step, navigate to the following menu:
The CS141 uses separate system services for communication, which can be started and stopped independently to each other:
This allows activating and deactivating the functions without having to restart the CS141 completely.
While Modbus and SNMP are used as the industry standard inside almost all higher-level monitoring systems, the UNMS server is only
necessary if you use the monitoring software UNMS 2 from GENEREX.
To enable or disable the according service, use the buttons.
