Data That Can Be Used in Equations
1-26
Computing equations can be set up using measured values and other computed values
as variables in computation-dedicated channels, and the computation can be executed.
The computed result can be recorded. Computation is performed every scan interval.
The computation-dedicated channels below can be used.
Model Number of Channels
Pen model 8
Dot model 12
In the table below, y represents the computed result. X and n represent the measured
value, a constant, etc.

In TLOG computation, the measured values of measurement channels or computed
values of computation channels can only be used. For all other computations, all of the
data types below can be used.
• Measured Values on Measurement Channels
Specified by the channel number. For channels that have scaling enabled, the scaled
values are used in the computation.
• Computed Values on Computation Channels
Specified by the channel number.
• Constants (K01 to K30)
The values assigned to K01 to K30 can be used as constants.
Range of values (maximum significant digits is 5):
–9.9999E+29 to –1.0000E–30, 0, 1.0000E–30 to 9.9999E+29
For the procedure to set the functions, see section 1.10, "Function Setup Guide."
Channel Names
0A, 0B, 0C, 0D, 0E, 0F, 0G, and 0J
0A, 0B, 0C, 0D, 0E, 0F, 0G, 0J, 0K, 0M, 0N, and 0P
Determines addition, subtraction, multiplication, and division.
Determines the power. y = X
Determines the square root.
Determines the absolute value.
Determines the common logarithm. y=log
Determines the exponent. y = e
Determines <, ≤, >, or ≥ of two elements and outputs "0" or "1."
Determines the AND (logical product), OR (logical sum),XOR
(exclusive logical sum) of two elements, NOT (negation) of an
element and outputs "0" or "1."
Determines the sum (SUM), the maximum (MAX), the minimum
(MIN), the average (AVE), and the maximum – minimum (P-P)
at specified time intervals. There are three timers for setting the
interval.
