Menu 12: Threshold detectors, variable selectors and brake control function

Menu 12 includes two threshold detectors which produce logic signals depending on the level of a variable value with respect to a threshold, and two
variable selectors which allow two input parameters to be selected or combined to produce a variable output. One menu 9 or one menu 12 function is
executed every 4ms. Therefore the sample time of these functions is 4ms x number of menu 9 and 12 functions active. A function is active if one or
more sources are routed to a valid parameter.
