Method for changing the system of standards
If you select a different system of standards in the "NSys" attribute, the script block
"OnChange()" is initiated.
●
Properties of a pipe part, "Script" tab, "OnChange()" script block
● Goal: COMOS changes beneath the node which contains the system of standards-
dependent standard tables to another node.
Example: Under the node "Y10 > M20 > Y30 > A10 System standard depending tables",
COMOS changes from "DIN/EN" to "ANSI/ASME".
● Effect: A different standard table is assigned to all attributes that are dependent on the
system of standards at pipe parts in the pipe part catalog. For this to happen, the structure
under the "A10 System standard depending tables" attribute must be built identically.
Examples for dependent attributes
● Flange standard
● Connection type
3.3.2 Managing standard tables for parameters
3.3.2.1 Definition of parameters
"Parameters are properties of a pipe part which are relevant to pipe specs. Their possible
values are restricted by the pipe spec to which the pipe part belongs:
The values (characteristics) permitted in principle for this parameter are listed in the standard
table. Each value corresponds to a standard table entry.
Example parameters:
● Nominal pressure
● Nominal diameter
● Material
● Material standard
● Technical norm
● Flange standard
