4.11 Calculation of Detected Data (Numerical Calculation)
This function calculates using the data detected by checkers and outputs the data to the external devices. Up to
1000 expressions (when 10 blocks are used) can be set for each product type.
•
PV500 can handle the values from -2147483648.000 to + 2147483647.000, which are -(2
31
) to (2
31
-1),
during calculation. When a calculating value exceeds the range, it is considered as an error (ER) and
an error signal (ERROR0) is output. In that case, the calculation result is output as “0”.
•
The setting limit is the maximum of 1000 expressions per product type combined with expressions of
Numerical Calculation. (After creating 1000 expressions of Numerical Calculation, you cannot create a
judgement expression any more.)
•
In Connector (Binary Window), Connector (Gray Window), and Connector (Gray Edge), you can
register some types of data into a Data R/W sheet from the setting windows. Refer to the description of
each checker for details.
•
When the judgement of the numerical calculation registered in a numerical expression is error (ER), it is
referred as “0” in the calculated result.
Example) When CA000 is error
No. Expression Result
CA001 = CA000 0
CA002 = CA000 + 500 500
4.11.1 Setting a Calculation
Creating a Calculation
1.
Select "INSPECTION” > “Num. Calcu.” from
the menu bar.
“Numerical Calculation” list is displayed.
Next to the calculation number, the beginning
part of an expression is displayed.
Tilting the ENTER key right in the list to display
the next page shows 63 characters of
expression and comment.
2.
Select a numerical calculation list and a
number to set.
The screen of numerical calculation setting is
displayed.
