Current output

Data points affected:

Start(Stop)AO1

•

IsAO1EnableTest

(Option Board)

Options:

 

• Click on the StartAO1 button to enter the test mode (TRUE) (Note: the Start button will

 

 

become the Stop button after clicking on it.)

 

• Click on the StopAO1 button to exit the test mode (FALSE) (Note: the Stop button will

 

 

become the Start button after clicking on it.)

 

Guidelines:

 

• The specified test value takes effect within one batch period of clicking the Start button

 

 

(see below).

 

 

Current output

Data points affected:

Output setting

•

AO2TestModeOutputPercent

(Expansion Board with

Options:

HART®)

• Enter the integer percentage of full scale for the analog output within the range [0, 100 %]

 

 

where 0% corresponds to the minimum output (4 mA) and 100% corresponds to the

 

 

maximum output (20 mA).

 

Guidelines:

 

• The specified test value takes effect within one batch period of clicking the Start button

 

 

(see below).

Data points affected:

Start/StopAO2

•

IsAO2EnableTest

(Expansion Board with

Options:

HART®)

• Click on the StartAO2 button to enter the test mode (TRUE) (Note: the Start button will

 

 

become the Stop button after clicking on it.)

 

• Click on the StopAO2 button to exit the test mode (FALSE) (Note: the Stop button will

 

 

become the Start button after clicking on it.)

 

Guidelines:

 

• The specified test value takes effect within one batch period of clicking the Start button

 

 

(see below).

 

 

 

The maximum length of time that the analog output can remain in the test mode is specified via the NonNormalModeTimeout data point. Note that this data point applies to other tests as well. The NonNormalModeTimeout data point can be changed using the Daniel MeterLink Edit/Compare Configuration screen. It can be set within the range [1, 30 min] and has a default value of 2 min.

6.3Digital Input

The Mark III meter provides one digital input (referred to as DI1). The polarity of the input is configured via the DI1IsInvPolarity data point as follows:

•FALSE - normal polarity (default setting), or

•TRUE - inverted polarity

The digital input is not configurable via the Daniel MeterLink Field Setup Wizard. It must be configured via the Daniel MeterLink Edit/Compare Configuration screen.

The value of the input is accessible via the DI1 data point.
