Siemens COMOS User Manual

Procedure
1.
"Column" field: Specify from which column of the nominal-diameter-dependent table the
value is read.
2. "Nominal diameter of connector" and "2. Nominal diameter of connector" fields: Specify for
which component connector the value is valid.
If the pipe part has only one nominal diameter: Select "Ignore" for "2. Nominal diameter of
connector".
3. Click the "OK" button.
3.5.2.7 Using the "Cat2(...)" function
Functional principle of "Cat2(...)"
● The "Cat2(...)" function reads the dimension value from a pipe part table you specify.
● The value is determined based on the parameter you define.
Requirement
You have selected the "Cat2(...)" function in the "Function" field of the "Define catalog access"
window.
Procedure
1. Click the "..." button next to the "Table" field.
The "Catalog selection" window opens. You see the base object of the pipe part and its
tabs.
2. Select the required table and click the "OK" button.
3. "Result column" field: Specify from which column of the table the dimension value is read.
4. "Search column 1" field: Specify the column to be used as the search parameter.
5. For pipe parts with two nominal diameters: Specify the column of the second search
parameter in the "Search parameter 2" field.
6. "1st attribute with search value" field: Specify which attribute of the pipe part is evaluated
to find the correct search row in the search column.
7. "2nd attribute with search value" field: For pipe parts with two nominal diameters. Same as
above.
8. Click the "OK" button.
3.5.2.8 Using the "S(...)" function
Functional principle of "S(...)"
The "S(...)" function uses the value from another pipe part attribute as the dimension.
