1.6 Computation Function and Report Function
(/M1, Option)
Computing equations are assigned to channels that are dedicated to performing
computations. Displaying computation channels and acquiring computed data can be
carried out in the same manner as in the measurement channels. The computation is
performed every scan interval.
Reports can be created, displayed, and stored. Report channels and report types are
set in the basic setting mode.
For detail, see Chapter 11.
Computation Channels
Model Channel
RD-MV102 Channels 31 to 34 (4 channels)
RD-MV104 Channels 31 to 34 (4 channels)
RD-MV106 Channels 31 to 42 (12 channels)
RD-MV112 Channels 31 to 42 (12 channels)
Types of Computations
The following types of computations can be performed.
Type Description
Four arithmetical operations Addition (+), subtraction (–), multiplication (
×
), and division (/)
SQR Computes the square root.
ABS Determines the absolute value.
LOG Determines the common logarithm.
EXP Determines the exponent.
Relational computation Determines <,
≤
, >,
≥
, =,
≠
and outputs “0” or “1.”
Logical computation Determines the AND (logical product), OR (logical sum), XOR
(exclusive logical sum) of two channels, NOT (negation) of an
arbitrary channel and outputs “0” or “1.”
Statistical computation (TLOG) Determines the average (AVE), maximum (MAX), minimum
(MIN), and maximum - minimum (P-P) at specified time
intervals for the specified channels. You can specify the
interval.
Rolling average Determines the moving average of the computed result at scan
intervals for the channel for which the equation is specified.
The sampling interval and the number of samples are specified
for each channel. The maximum sampling interval is 1 hour, the
maximum number of samples is 64. The initial setting is set so
that the rolling average is disabled.
The following elements can be used in the computing equations.
Element Description
Constants (K01 to K12) Set by the computation function.
Communication input data Set by the communication function.
