Foundation Fieldbus 3-45

With the EXA, the channel values are displayed on the display indicator, independant of the scaling in the
AI blocks.

(2) Setting the output mode

Access the L_TYPE parameter.

Set the output mode.

1: Direct

(Sensor output value)

2: Indirect

(Linear output value)

3: IndirectSQRT

(Square root extraction

output value)

(3) Setting the damping time constant

Access the PV_FTIME parameter.

Set the damping time (in seconds).

(4) Simulation

By optionally setting the input value to the calibration range and status, perform simulation of the AI
function block.

Access the Simulate Value parameter.

Set an optional input value.

Access the Simulate Status parameter.

Set the status code.

Access the Simulate En/Disable parameter.

Set whether Simulation is enabled or disabled.

2: Enabled

1: Disabled

If simulation is enabled, AI block uses Simulate Status and Simulate Value as the input, and if disabled, the
AI block uses Transducer Status and Transducer Value as input.
Refer to Section 3.4.3 Simulation Function.

3-7-4 Setting the Transducer Block

To access function specifics of the EXA of the transducer block, the DD (Device Description) for EXA needs
to have been installed in the configuration tool used. For integration of DD, refer to “Integration of DD” in
Section 3-2-4.
