TLOG Computation
TLOG computation determines the sum, maximum, minimum, average, or the difference
between the maximum and minimum of a specific channel for each interval determined by a
timer.
In the explanation below, an expression containing a computing element, an internal switch
(S), and a flag (F) cannot be written in e1. In addition, only one TLOG computation can be
specified in a single computing expression.
TLOG.MAX()
Maximum value
(Syntax) TLOG.MAX(e1)
(Condition) Determines the maximum value of channel e1.
TLOG.MIN()
Minimum value
(Syntax) TLOG.MIN(e1)
(Condition) Determines the minimum value of channel e1.
TLOG.AVE()
Average value
(Syntax) TLOG.AVE(e1)
(Condition) Determines the average value of channel e1.
TLOG.SUM()
Sum value
(Syntax) TLOG.SUM(e1)
(Condition) Determines the sum of channel e1.
TLOG.P-P()
Maximum – minimum value
(Syntax) TLOG.P-P(e1)
(Condition) Determines the maximum - minimum value of channel e1.
TLOG.PSUM()
Sum value
(Syntax) TLOG.PSUM(e1)
(Condition) Determines the sum of channel e1.*

ExpressionExample
TLOG.MAX(0001)+K001*SQR(0002)
ExamplesofEquationsThatAreNotAllowed
TLOG.AVE(0001)+TLOG.AVE(0002)
Reason: TLOG appears twice in one equation.
TLOG.AVE(ABS(0001))
Reason: A computing element is used inside the parentheses.
