TLOG Computaton
Only measured values and computed values can be used in TLOG computation. In the
explanation below, e1 is used to represent a measurement or computation channel. You
cannot specify an equation that contains a computing element inside e1. In addition, only
one TLOG computation can be specified in a single computing equation.
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.
Equaton Example
TLOG.MAX(01) + K01*SQR(02)
Examples of Equatons That Are Not Allowed
TLOG.AVE(01) + TLOG.AVE(02)
Reason: TLOG appears twice in one equation.
TLOG.AVE(ABS(01))
Reason: A computing element is used inside the parentheses.
