DMUX8_DI: Demultiplexer 1 of 8 double integer values
The DMUX8_DI (FC414) block switches the double integer input to one of the 8 outputs in dependence of a selector.
Functionality
The block switches the input [In] to the output [Out0] ... [Out7] defined by selector [K]. All other outputs are set to default value [DefVal].
If the value of input [K] is smaller than 0 or greater than 7, all outputs [Out0]...[Out7] are set to [DefVal].
The block can be cascaded e.g. to demultiplex 16 outputs. To do this, several DMUX8_DI blocks can be switched in parallel to the same input value [In]. The output [ReqK] is automatically adjusted by subtraction. This allows any number of DMUX8_DI function blocks to be cascaded.

Application
The block normally is used to reset signals interconnected via a multiplexer.
For example, a communication path featuring an integer and double integer variable only can be used to transmit up to 8 different values in sequence.
