VXi VT1422A 사용자 설명서

•

The <range> and <offset> parameters define the allowable input values to the 

function (domain). If values input to the function are equal to or outside of 
(

±<range>+<offset>), the function may return ±INF in IEEE-754 format. 

For example; <range> = 8 (-8 to 8), <offset> = 12. The allowable input values 
must be greater than 4 and less than 20. 

•

<func_data> is a 512 element array of type uint16.

•

The algorithm syntax for calling is: <function_name> ( <expression> ). for 

example:

O116 = squareroot( 2 * Input_val );

•

Functions must be defined before defining algorithms that reference them.

•

ALG:FUNC:DEF 'F1',8,12,<block_data>

•

Use VXIplug&play function: hpe1422_sendBlockUInt16(...)

sets the delay from Scan Trigger to start of 

output phase.

•

The algorithm output statements (e.g., O115 = Out_val) DO NOT program 

outputs when they are executed. Instead, these statements write to an 
intermediate Output Channel Buffer which is read and used for output AFTER 
all algorithms have executed AND the algorithm output delay has expired 
(see Figure 7-1). Also note that not all outputs will occur at the same time 
but will take approximately 10 µs per channel to write.

•

When <delay> is 0, the Output phase begins immediately after the Calculate 

phase. This provides the fastest possible execution speed while potentially 
introducing variations in the time between trigger and beginning of the Output 
phase. The variation can be caused by conditional execution constructs in 
algorithms or other execution time variations. 

•

If <delay> is set to less time than is required for the Input + Update + Calculate, 

ALG:OUTP:DELAY? will report the set time, but the effect will revert to the 
same that is set by ALG:OUTP:DELAY 0 (Output begins immediately after 
Calculate).
