HTTP - XML tags
XML tags, TCP/IP communicationThe values, monitored by measuring sensors are displayed in the defined .XML page (for example values.xml) and they can be read easily from XML tags by any application. It represents the most efficient way of retrieving data for Machine-to-Machine TCP/IP, because values from all sensors are stored in one file. XML entry is comprehensible for a man as well, process independent on SW platform and information can be retrieved even without a special software.
Note: We recommend using XML as the input interface for your SW applications.
Example of XML record for a thermal sensor:
<Entry>
<Name>TempSens1</Name> - sensor name
<Type>RS232</Type> - sensor type
<ID>T0</ID> - identification
<Temper>15</Temper> - actual temperature
<TempRange>05.0 - 35.0</TempRange> - allowed temp. range
<Alarm>none</Alarm> - alarm state
<State>0</State> - sensor state
</Entry>
Notice: majority of the Poseidon models contains two XML files which differ in range of commands. The smaller file (typically values.xml) is used for print-out of connected sensors state. The second file (typically setup.xml) contains full device configuration data and you can dump sensor values, names of sensors, their alarm state configuration and others using your SW application. If the setting of Poseidon allows it, you can change some parameters directly in this file. |
