TLOG Computation
In the explanation below, an expression containing a computing element in e1, an
internal switch (S), a relay (I), or flag (F) cannot be written. 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.
Expression 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.
