When EN = 1, the value at the selected input Ix is continuously output and
refreshed with every processing cycle.
The fault contact MX..E1 closes if an invalid parameter is present at the
channel number input MX..K.
Example
A drive is required to run at a fixed speed and at three dependent speeds.
It receives the setting from a multiplexer function block.
MB08 defines the number of the channel that is to reach the output.
The fixed speed is set as a constant at input MX01I1, the subsequent inputs
are assigned the variable values from markers MB01 to MB03. The setpoints
at output MX01QV of the function block are output at MB04.
The function block is first activated in the circuit diagram by marker M33.
The following figure shows the association.
