PARA – Block with input-defined array parameter

Block SymbolLicensing group: STANDARD
PIC

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).
