CLOG Computation
Only data of I/O channels, math channels, and communication channels can be used in
CLOG computations. Up to 30 channels can be written in the parentheses.
In the explanation below, an expression containing a computing element cannot be written
to e1, etc. In addition, only one CLOG computation can be specified in a single computing
expression.
CLOG.SUM()
Sum value
(Syntax) CLOG.SUM(e1.e2.e4-e6)
(Condition) Determines the sum of the data of channels e1, e2, e4, e5, and e6 that are
measured at the same time.
CLOG.MAX()
Maximum value
(Syntax) CLOG.MAX(e1.e2.e4-e6)
(Condition) Determines the maximum value among the data of channels e1, e2, e4, e5,
and e6 that are measured at the same time.
CLOG.MIN()
Minimum value
(Syntax) CLOG.MIN(e1.e2.e5.e7)
(Condition) Determines the minimum value among the data of channels e1, e2, e5, and
e7 that are measured at the same time.
CLOG.AVE()
Average value
(Syntax) CLOG.AVE(e1-e6)
(Condition) Determines the average value among the data of channels e1 to e6 that are
measured at the same time.
CLOG.P-P()
Maximum – minimum value
(Syntax) CLOG.P-P(e1.e2.e5.e7)
(Condition) Determines the difference between the maximum and minimum values among
the data of channels e1, e2, e5, and e7 that are measured at the same time.
ExpressionExample
CLOG.MAX(0001.0002.A004-A006)+K001*SQR(0002)
ExamplesofEquationsThatAreNotAllowed
CLOG.AVE(0001.0003.0005)+CLOG.AVE(0002.0004.0006)
Reason: CLOG appears twice in one equation.
CLOG.AVE(001.ABS(001))
Reason: A computing element is used inside the parentheses.
