 Outline of operation
 This instruction is different from CT instruction. The range settable by the setting value [S] is
U0 to U65535.
 All counters are subtraction preset counters.
 When the reset input is switched from ON to OFF, the value of the setting value area CS is
preset in the elapsed value area CE.
 When the reset input is on, the elapsed value is reset (cleared to zero). When the count
input changes from the off state to the on state, the setting value is subtracted. When the
elapsed value becomes U0, it is output to the counter contact.
 When the count input and reset input turn on simultaneously, the reset input has priority.
 When the rise of the count input and the fall of the reset input are detected at the same time,
the count input is ignored and only the preset is executed.
 It is also possible to describe OT instruction right after the counter instruction.
 For details of this instruction, refer to the description of CT instruction in FP7 CPU Unit
Programming Manual.
