PARA – Block with input-defined array parameter

Block SymbolLicensing group: STANDARD

Function Description
The PARA block allows, additionally to the standard way of parameter setting, changing one of its parameters by the input signal. The input-parameter pair is uRef and apar.

The Boolean input LOC (LOCal) determines whether the value of the apar parameter is read from the input uRef or is input-independent ( $LOC = on$ ). In the local mode $LOC = on$ the parameter apar contains the last value of input uRef entering the block right before LOC was set to on.

The output value is equivalent to the value of the parameter ( $yRef = apar$ ).

Inputs

uRef	Array reference	Reference
LOC	Activation of local mode	Bool
	off .. The parameter follows the input on ... Local mode active

Output

yRef	Array reference	Reference

Parameters

SETS	Set array size flag. Use this flag to adjust the size of array when setting the parameter.	Bool
nmax	Allocated size of the apar array $↓$ 10 $⊙$ 100	Long (I32)
etype	Type of members of the apar array $⊙$ 8	Long (I32)
	2 .... Byte 3 .... Short 4 .... Long 5 .... Word 6 .... DWord 7 .... Float 8 .... Double 10 ... Large
apar	Internal value of the parameter $⊙$ [0.0 1.0 2.0 3.0 4.0 5.0]	Double (F64)
