iconName
r
The icon graphic that will be used to display the sensor on the M2M
Gateway (default COMBO); the graphic must already exist on the
server (on the UI of the M2M Gateway, click the Info button, then
Icons). Note: this attribute is used only by the M2M Gateway and it
does not exist in the RTU.
lastDate
r
The date the sensor was sampled last time.
putdataDate
r
The date of the sensor’s last values pushed unto the server (M2M
Gateway). Normally the equivalent RTU attribute is used, unless a
sensor has a different schedule. This is an RTU internal attribute, it
does not exist on the server.
sdiAddress
r/w
The SDI sensor address. This attribute is valid for SDI-12 sensors only.
sdiInfo
r
Returns the result of the "I" (Info) command to an SDI-12 sensor. This
attribute is valid for SDI-12 sensors only.
sdiMethod

The acquisition method used; as per the SDI-12 specification, this can
be M, C, R, MC, CC, RC and V. This attribute is valid for SDI-12 sensors
only.
sdiPostmethod
r/w
An (optional) SDI-12 command sent after sampling the sensor. Usually
this is an SDI-12 X command. The address and the SDI-12 terminator (!)
should be skipped (the address is defined by the sdiAddress attribute).
This attribute is valid for SDI-12 sensors only.

r/w
Engineering Unit Identification. Each tag has a value type (e.g., mm,
ºC, km/h, etc.), which in turn has an ID assigned. The EUID can be read
by a data retrieving client (e.g., over the addUPI protocol) and display
the tag values with the proper type. A list of all defined EUIDs can be
reached over the M2M Gateway UI: click the Info button, then the
Engineering Units tab. This attribute does not exist on the RTU.
