TLOG Computation
In the explanation below, you cannot enter an expression that contains an operator or
function, an internal switch (S), a relay (I), or a flag (F) for e1. Also, an expression can
contain only one TLOG function.
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(01)+K01*SQR(02)
Examples of Invalid Expressions
TLOG.AVE(01)+TLOG.AVE(02)
Reason: TLOG appears twice in one expression.
TLOG.AVE(ABS(01))
Reason: A function is used inside the parentheses.
