Function
parameter in the
Math function
mode
Basic math functions implemented into the device are: addition, subtraction,
multiplication and division. The unit allows the operation of logic functions, trigonometric,
array operations, determining the arithmetic mean, finding maximum and minimum values,
and many other functions that are discussed in the table below. After pressing the button next
to the
Function
label go to the math function menu. This menu consists of the following
parameters (Note! Not all parameters are available for each function):
–
Function
– available for all math functions, by pressing the button next to this label
a list of available math functions appears, from which the user can select the
appropriate function,
–
Type of source X
– available for certain math functions. Available types are:
•
channel
– means that the
'X'
source will be a logical channel selected from
the list in the
Source X
parameter,
•
value
– means that the
'X'
source will be a constant value entered in the
Source X
parameter,
–
Source X
– available for certain math functions. Depends of the
Type of source X
parameter. This parameter allows the user to:
•
select a logical channel from the list (
Type of source Y=channel
),
•
or enter a set point value (
Type of source Y=value
),
–
X error handling
– available for some math functions, depending on this parameter,
the user can set the following options:
•
errors forwarded to result
– when the result of the selected channel
(
Source X
) is a state: Error, Hi, Lo, or undefined, then the output received
states:
Err
,
Hi
or
Lo
,
•
skip erroneous channels
- means that these channels, which result in a status
of
Error
,
Hi
,
Lo
are ignored in the calculation of a selected math function,
–
Init. value mode
– available for some math functions, depending on this parameter
the user can set the following options:
•
channel
– means that the initial value will be loaded from the selected logical
channel,
•
value
– means that the initial value will be a constant value entered in the
Initial value
parameter,
–
Init. value source
– available for certain math functions, selects a logical channel
from the list which will be the initial value source for the function,
–
Initial value
– available for certain math functions, a constant value which will be
the initial value for the function after its reset or device start,
–
Max. value mode
– available for some math functions, depending on this parameter
the user can set the following options:
•
channel
– means that the maximal value will be determined by the selected
logical channel,
•
value
– means that the maximal value will be a constant value entered in the
Maximal value
parameter,
