Converts an analog signal into a binary signal which
 varies in the time. The binary output has a
 pulse-proportional relay action in the dead zone, if
 MinOut < MaxOut, else on/off-action with hysteresis.

 The digit 2 in the object name comes from the output
 which may have two distinct values with a two-step
 action; e.g. full on / full off but also with the
 meaning of open / closed, forward / backward, or right
 / left etc.

 Two cases exist:
 1. MinOut < MaxOut

   If OutVal < MinOut the Order is always FALSE and if OutVal > MaxOut the Order is always TRUE.

   When MinOut = OutVal = MaxOut the output, Order, has a pulse-proportional relay action
   with the cycle time Period .

   At pulse-proportional relay control the proportion between On/off is the same as the
   proportion of (OutVal - MinOut) / (MaxOut - MinOut)

   This quotient is updated at every scanning. If a period starts with an on-state it will
   remain until,
   (OutVal(t) - MinOut) / (MaxOut(t) - MinOut(t) * Period = time from last change of state

   After this it will be off-state until,
   1 - (OutVal(t) - MinOut) / (MaxOut(t) - MinOut(t) * Period = time from last change of state

 2. MinOut = MaxOut gives the output an on/off-action with hysteresis, likewise a combined
    Compl and Comph object

 Input signal, e.g. the OutChange of a Pid object.

 The performance of the output signal is different
 depending on MinOut < MaxOut or MinOut ³ MaxOut. See
 above.

 Program cycle period in seconds.

 The upper and lower end of the dead zone. Two cases
 with different performance depending on MinOut < MaxOut
 or MinOut >= MaxOut.

 Pulse period, in seconds, at pulse-proportional relay
 action.

 Accumulated time in seconds counted from the last
 change of state.
