Class Select
Version	1.0
Modified	08-MAR-2026 11:05:32.00
Code	rt_plc_arithm.c

 Selects one out of two analog quantities.


 The selected value is controlled by a binary quantity
 in the following way:

  VAL = HIG and NOT = LOW, if con(trol) is TRUE
  VAL = LOW and NOT = HIG, if con(trol) is FALSE
