Timing Chart:
Case 1: If CTUD counts up normally, the value of CTUD1_CV is increased by 1 whenever
CTUD1_CU is triggered once.
Case 2: When CTUD1_Reset is TRUE, CTUD1_CV is cleared to 0, CTUD1_QU changes to
FALSE and CTUD1_QD changes to TRUE.
Case 3: When CTUD1_Load is TRUE and CTUD1_CV equals CTUD1_PV, CTUD1_QU changes
to TRUE and CTUD1_QD changes to FALSE. At the moment, if CTUD1_CD is triggered,
the instruction can not count down.
Case 4: If the instruction counts down normally, CTUD1_QU is FALSE when CTUD1_CD is
TRUE. The value of CTUD1_CV is decreased by 1 whenever CTUD1_CD is triggered
once. CTUD1_QD is TRUE when the value of CTUD1_CV is decreased to 0.
