TRANSMITTER P***
PARAMETERS
(THE 3102 AND 3105)
NOTE:
For relevant menu structures, refer to Appendix D or Appendix E, whichever
is appropriate for your HART Master Device.
The 'P' prefixed parameters (e.g. P010) are for adjusting the operational
set-up of the transmitter. Parameters are listed here in numerical order.
P000 (Message)
P000 Description:
This allows a general 32-character message to be edited (12 characters on a
Rosemount 3490 Series Control Unit). It can be used for any purpose, such
as recording the initials of the person who programmed it, a support contact
number, details of last programming change, etc.
P001 (Tag Number)
P001 Description:
This is for editing a tag number of up to 16 characters for the transmitter
(8 characters on a Rosemount 3490 Series Control Unit). The tag is typically a
reference number, but it can also be used to identify the location or duty of the
transmitter in plant item terms.
NOTE:
This tag helps identify the transmitter being interrogated when using a HART
Master Device such as the Rosemount 3490 Series Control Unit.
P002 (Description)
P002 Description:
This is for editing an optional 12-character description to expand on P001, if
needed.
P004
(Final Assembly Number)
P004 Description :
This is a read-only parameter showing a multiple-digit number, used by the
factory to track the manufacturing history of an individual transmitter.
P005 (Serial Number)
P005 Description:
This is a read-only parameter showing a multiple-digit number, used by the
factory to identify a transmitter,
P010 (Bottom Reference)
P010 Description:
The Bottom Reference value is the distance measured vertically along the
ultrasonic beam path from the transmitter face to the zero level of the vessel
or open channel.
The zero level establishes where the transmitter starts to measure the
process value (PV). It is not necessary to have the 4 mA output commence at
the zero level; the 4 mA start-point can be any liquid height above (or below)
this zero level.
This parameter is important for calibrating or configuring the transmitter.
