Group
In many cases, when there is a problem with one bolt, reject actions must be performed not only on this
bolt but with others within the station. In PowerMACS it is therefore possible to put bolts together in
groups.
A group is a set of bolts, which are run completely separate from each other, but have some form of
relationship. In case of reject management, they are considered to belong to the same group, and special
actions can be specified for bolts within the group.
The bolts in a station can be divided into groups of bolts as in following figure:
St 1
bolt
station
groups
Gr 1
Bolt 1
Bolt 2
Gr 2
Bolt 3
Bolt 4
Gr 3
Bolt 5
Bolt 6
All bolts belong to the station St 1. Bolts 1 and 2 belongs to group Gr 1, bolt 3 and 4 to group Gr 2, bolt 5
and 6 to group Gr 3. A special case is bolt 3 and 5, which both belongs to two groups at the same time.
