General Description
The User Mode Switch function block is used to monitor an operating mode
switch in the user system or device.
The operating mode switch that can be connected with this function block
must be a 1-of-N type switch (i.e., one of N contacts is ON). The function
block supports a maximum of eight inputs and corresponding outputs.
The output corresponding to the input that is active is turned ON. If an error is
detected for the function block, however, all outputs will turn OFF.

function block property dialog box.
