Marking of the measurement point / TAG number

The TAG number, also called marking of the measurement point, contains important customer information linking a field device with the operative task.
The identification of the measurement point inside the plant is the primary value. That is why a TAG number is assigned to the measurement
point and has to be replaceable on the device. This can be done "outside" (label) as well as "inside" (software) the device. Furthermore the accompanying device documents or the order also contain the TAG number.
The TAG information can be given to Endress+Hauser together with the order. This can be done for example in the form of an Excel file.

Ordering note:
The TAG number is normally a part of the order for each individual unit. 
Subsequent orders are only possible for metal TAGs. In these cases the tags are sent to the customer separately.

Field bus TAG
Field bus TAG marks the measurement point using the electrical interface. (PCP, HART, PA and FF).
On standardized field busses only those parameters that are defined by the respective norms are supported.

HART:

max. 8 characters

HART Descriptor:

max. 16 characters

Profibus:

max. 32 characters

Foundation Fieldbus

max. 32 characters

The Field bus TAG can be modified subsequently by the customer using the set-up.


Metal TAG
The metal TAG can be removed and transferred to a replacement device. It can be fastened to parts of the plant itself. The metal TAG is shipped together with an attachment wire.


TAG on device
This TAG is permanently attached to the device either as a foil or lasered or engraved.


Customer TAG
Customers can also issue an own tag plate or stick-on label and provide it with the order. The TAG number must already be engraved or 
printed on the tag plate. These TAG plates then are shipped fastened to the device.


Commissioning Label
The TAG number is printed on a cardboard label. The label is shipped fastened to the device. After installation the commissioning label can be removed easily and is exerted for the configuration of the instrument in the control room.
