OUTPUT/HOLD MODE

The Output/Hold Mode of Operation provides the

ability to view a limited number of Transducer Block

(TB) and Analog Input (AI) Function Block

parameters. Fieldbus Foundation requirements

prevent local adjustments using the HMI of the

transmitter for function block parameters other than

those located in the TB. Parameter viewing is limited

to the TB Process Variable Range, AI Block mode

status, AI Output Value, AI Field Value, and AI

Process Value.

The TB Range State contains the process value low

and high range limits. These represent the range

limits used to define the Field Value.

The AI Block information shows the current mode

(i.e., Out of Service – OOS, Auto, or Manual) of the

specified function block (i.e., AI1 or AI2). For in

service blocks, information for the Output, Process

and Field Values is shown. If the block is out of

service, the Process and Field Values will contain the

last values written to them when the block was in

service. If the block was never in service, these

parameters will be zero.

Mode and States of Operation

CONFIGURE MODE

The Configure Mode of Operation establishes the

operating parameters of the transmitter. These

parameters include analyzer type, temperature sensor

type, temperature compensation type, and diagnostic

functionality.

Upon selecting the Configure Mode at the local HMI,

a query to Modify or View the configuration will be

presented. The Modify Configure State enables

analyzer options to be set and saved into memory.

To access the Modify State, the Transducer Block

must be put Out Of Service either from the local HMI

upon entry into the Modify State or from a remote

configuration tool.

Since the Modify State can be secured, the

configuration of the transmitter can be viewed using

the View Configure State without violating secured

settings. To provide quick and easy access to edit

transmitter parameters from the View Configure State,

a Hot Key function provides immediate access to the

viewed parameter using the ENTER key. If the

Modify Configure State is secured, the security code

will be requested before entering into the Modify

Configure State.
