2 MATH CONFIGURATION
2.1 Math Block Description
Notes.
•Up to twelve Math Blocks, configured individually
using the 'Math Pad' –see Fig. 2.2.
•Each Math result has its own Long and Short Tags
and Engineering Range
•Up to 18 different preset functions –Table 2.4
•Constants up to three decimal places
•Maximum equation length –40 characters
•Up to three digital signals per equation
Individual recording channel signals, analog and digital sources
can be combined in a Math Block to produce a customized
recording channel or retransmission source.
Typical examples include adding/subtracting the values of a
number of analog sources together to form one recording
channel.
More complex blocks can also be implemented that determine
relative humidity, mass flow or zirconia oxygen concentration.
Digital signals can be used in Math Blocks to enable/disable the
output when certain conditions are true.
2.2 Typical Math Block – Fig. 2.1
Each math block comprises any number of sources, constants,
operators and functions, to a maximum length of 40 characters,
as indicated in Fig. 2.1.
Possible operators, sources and functions are listed in
Tables 2.1 to 2.4
2.3 Operators – Table 2.1
Fig. 2.1 Typical Math Block
Table 2.1 Operators
Notes.
•Operators are evaluated from left to right.
The above equation is evaluated as:
[(a1 + 52.4)* Log(a2)] –md2 and NOT as a1 + (52.4* Log(a2)) –md2.
•Functions cannot be nested within other functions.
To enter an equation requiring nested functions it is necessary to use another math block,
e.g. to evaluate the equation:
a1 + a2
52.4 –a3 proceed as follows:
•Enter math block 1 as m1 = a1 + a2/m2
•Enter math block 2 as m2 = 52.4 –a3
•Digital signals (md1 to md3) are evaluated as 0 (inactive) and 1 (active).
Thus in the following example:
m1 = a1 + a2*md1
the sum of (a1+ a2) is set to zero if the digital input md1 is also zero.
2.4 Constants
Math blocks may contain any number of constants, each with a
limit of three decimal places, up to the maximum of 40
characters for the whole block. The maximum range of each
constant is 9999 to –999

2.5 Analog Sources –Table 2.2
Sources can be either analog or digital.
Analog sources are identified within a math block by the preset
mnemonic shown in Table 2.2.
2.6 Digital Sources –Table 2.3
Up to three digital signals, identified within the Math Pad as md1,
md2 and md3, can be used within each math block. These
signals must be assigned to a digital source from Table 2.3 prior
to selection within the math pad.

2.9 Standard Functions
The following examples, using preset functions available on the
Math Pad, are included for easier reference.
2.9.1 Trigonometric Functions
Three trigonometric functions, Sin(x), Cos(x) and Tan(x) return
the Sine, Cosine and tangent of the variable x.
Note. The variable x must be specified in Radians,
where 1°= π/180 Radians.
For example, to find the Sine of 90°, first convert
degrees to radians:
90°= (90 x π) / 180 = π/2 ≈1.571Radians
The equation is entered as Sin(1.571)
2.9.2 Statistical Functions –Table 2.5 & Fig. 2.5
Statistical functions can be used to calculate the average, rolling
average and standard deviation of an analog variable.
2.9.3 Logarithmic Functions
The logarithmic functions Log(x), Ln(x) and excan be used to
scale process inputs.
Example –the output of vacuum gauges follow a logarithmic
curve and this must be linearized, therefore the antilog of the
input must be derived :
Linear Vacuum = k.10(Vacuum Gauge Output)
2.9.4 Relative Humidity –Fig. 2.6
Relative humidity is calculated using the following formula:
VPSd
(VPSw –AP(Td –Tw)
RH = 100
Where
VPSw = Saturation Vapour Pressure at Wet Bulb
Temperature
VPSd = Saturation Vapour Pressure at Dry Bulb
Temperature
Td = Dry Bulb Temperature
Tc = Wet Bulb Temperature
P = Total Atmospheric Pressure (1000 mbar)
A = Psychometric Constant (6.66 x 10–4)
RH = % of Relative Humidity
A relative humidity calculation requires two inputs, one from a
wet bulb sensor and one from a dry bulb sensor. Both of these
inputs are incorporated into the equation as analog.
RH tables are based on the use of an aspirated psychrometer
having an air velocity of at least 11.5 feet per second or 3.5
meters per second across the bulb sensors.
Inputs used for wet and dry bulb measurement must be in the
ranges 0 to 100ºC or 32 to 212ºF. The result must be set to 0 to
100.0% RH.
