 Channel101:ResetCount
Calculates the number of times the pulse sum value is reset.
The expression “((102+P01).GE.K01)” is set to 1 when “the previous pulse sum value
(102) + the current pulse count (P01)” is greater than the reset value (K01). Otherwise,
the expression is set to 0. The value of channel 101 is incremented when the pulse
sum value exceeds the reset value.
 Channel102:PulseSumValue
Calculates the pulse sum value.
Under normal conditions, the pulse sum value TLOG.SUM (P01) is calculated. When
the pulse sum value is greater than or equal to the reset value (K01), the pulse sum
value is set to the amount exceeding K01.
 Channel103:TotalSumValue
Multiplies the reset value (K01) by the reset count (101) and adds the pulse sum value
(102) to derive the total sum value.
Note
• Thecomputationisperformedinorderfromthechannelwiththesmallestchannelnumber
in one scan interval. If the channel number in the expression is greater than or equal to the
channel number in which the expression is assigned, the previous computed result (previous
value) is used for the channel in the expression.
• Ifthepulseinputvalueofthescanintervalisgreaterthantheresetvalue,correct
computation cannot be achieved.
