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.
Expression Example
TLOG.MAX(0001)+K001*SQR(0002)
Examples of Equations That Are Not Allowed
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.
