5.5.59 Multiplexer

Fashion: Classic:
Short Description
This function multiplexes the WORD inputs. It is used to route the value of one of the inputs selected by
the ADDRESS input to the output. The input is routed to the output on each rising edge of the
VALIDATION input.
The BASE ADDRESS parameter allows several blocks to be used at the same time to multiply inputs.
The Parameters tab contains:
BASE ADDRESS（corresponding to Input 1): Contains the address of the INPUT 1 input.
Retentivity: Chooses whether or not the function is reinitialized if the controller power supply is
disconnected.
When they are not connected, the digital input is in the OFF state and the WORD inputs contain 0.
Example:
When the BASE ADDRESS parameter contains the value 0 these inputs have addresses 0, 1, 2, 3
respectively, and in this case if the ADDRESS input equals 2 the VALUE of the third input will be copied to
the output.
If a second block is being used, 8 inputs can be demultiplexed by putting the value 4 as the BASE
ADDRESS in the second block and connecting the VALIDATION and ADDRESS inputs to the same source.
