Omega Engineering M-4066 manual Device Tag Names, Temperature

Device Tag Names

The Server uses device tag names to allow access to the I/O data and specific operational information. Tag names are dependent on the type of devices used.

Temperature

(OMWT-TEMP15, OMWT-THERM): TEMPn or 'T' Prefixed Topic Names online (R) - indicates if the device is communicating (0 or 1) nodaladdress (R) – (TCP/IP Receiver). The node address starts at 1. For

TCP/IP Receivers, the node address corresponds to the node number for the TCP/IP connection.

repeateraddress (R) – (Wireless mode) contains the location identifier of the OMWT-REPEAT repeater. If the sensor did not pass through a repeater then the value is 0.

polltime (R/W) - how often to poll the device (in milliseconds) serialno (R) - registration number of the temperature sensor input (R) - current temperature in engineering units input.raw (R) - current temperature in ºC

input.units (R/W) -engineering units of the input tag (ºC, ºF, or ºK). When this tag is written, it changes the temperature scale in the input.value tag. input.units must be one of the following: "Celsius",”C”, "Fahrenheit",”F”, or "Kelvin",”K”.

input.deadband (R/W) - filtering deadband in ºC

input.conv (R/W) - calibration and unit conversion parameters string. (Cal1Raw,Cal1Engr,Cal2Raw,Cal2Engr)

input.desc (R) - General identification description field.

(R) – indicates that the tag is readable.

(R/W) – indicates that the tag is both readable and writeable. OPC Write operations will either change an I/O point at the device, or an operation will be performed.
