OMWT-SOFT-OPC Server OMWT-SOFT-OPC Server Tags N 35
CNTTEMP: CNTTEMPn
(OMWT-DOORCNT)
online(R) - indicates if the device is communicating (0 or 1)
polltime(R/W) - how often to poll the device (in milliseconds)
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.
serialno(R) - registration number of the temperature sensor
dio.inputa(R) – state of the input, 1 or 0
dio.inputb(R) – state of the input, 1 or 0
cnt.input(R) - current count from the senosr
cnt.input.diff (R/W)- current count from the time the OMWT-SOFT-OPC
was started or when the variable was reset to 0.
cnt.input.time(R) - time in milliseconds of last update (uses Win API
GetTickCount())
cnt.input.scale(R/W) - value multiplied against the counts
cnt.input.units (R/W)- units description field
cnt.input.desc(R/W) - general purpose description field
temp.input (R) - current temperature in engineering units
temp.input.raw (R) - current temperature in ºC
temp.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”.
temp.input.deadband (R/W) - filtering deadband in ºC
temp.input.conv (R/W) - calibration and unit conversion parameters string.
(Cal1Raw,Cal1Engr,Cal2Raw,Cal2Engr)
temp.input.desc(R/W) - 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.
