ASSIGNING DEVICE TAG AND NODE ADDRESS
The calibration number is more than a correction factor, or K- factor, for the sensor. The first five digits represent the low frequency gain. The ninth through thirteenth digits represent the high frequency gain. Both numbers are normalized from an ideal number of 10000. Standard configurations use the low frequency gain, but in noisy applications it may be worthwhile to switch to the higher frequency. An additional transmitter procedure, called Auto Zero, is recommended to perform at the higher coil drive frequency. The seventh and eighth digits represent the zero offset at both frequencies where the nominal value is 50. Empty pipe functionality is a transmitter feature that is controlled by a parameter in the transducer block. To turn off this feature, see Appendix C.
The 8732E Magnetic Flowmeter Transmitter is shipped with a blank tag. The device is shipped with a default address of 126.
If the tag or address needs to be changed, use the features of the configuration tool. The tools do the following:
•Change the tag to a new value.
•Change the address to a new address.
BASIC SETUP AI Block
The Analog Input (AI) function block processes field device measurements and makes them available to the master. The output value from the AI block is in engineering units and contains a status indicating the quality of the measurement. The measuring device may have several measurements or derived values available in different channels. Use the channel number to define the variable that the AI block processes. The 8732E transmitter only supports “Flow” as AI Block variable.
