Setting the AI Function Blocks

The AI function block is a unit of the software.
During execution, it incorporates data from the SENSOR transducer block. After execution, it

updates analog outputs and processes newly generated alarms. AI function blocks can provide a

discrete output which shows the status of LO, LO_LO, HI, or HI_HI. In terms of function, there is

no difference between the three AI function blocks provided in FLXA21.

Function Blocks

The AI function block, via the Channel, incorporates analog signals from the transducer block,

performs scaling processing, filtering, signal linearization, fail safe control and alarm processing

before outputting. It has the function to generate a discrete output. Figure 4.1 presents the AI

function block.

Setting the output scale

As explained in section 4.2.4 the OUT_SCALE can used to convert the channel’s value to a

different scale.
The default value is 0.0 to 100.0%.
Change this if necessary.

For AI1 set L_TYPE to Direct
With the FLXA21, the channel values are displayed on the display indicator, independent of the

scaling in the AI blocks.

Setting the output mode

Access the L_TYPE parameter.

Set the output mode.

0: Direct

(no linearisation)

10: Square root

(Square root extraction

output value)

Setting the damping time constant

Access the PV_FTIME parameter.

Set the damping time (in seconds).
