9.2 Setting the Computing Equation
TLOG Computation
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.
Equation Example
TLOG.MAX(01) + K01*SQR(02)
Examples of Equations 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.
