14.5 Set-Up Modification Generator
The principal task of the Set-Up Modification Generator is the display of set-ups, the creation of changeover
instructions and the creation of follow-up set-ups required in the production of given PCB types.
An SMD production line uses a sequence of different set-ups in the assembly of PCBs. The set-up data required
are held in the master data storage. The actual physical changeover procedure is carried out by the operator.
The user interface of the Set-up Modification Generator provides the required displays of set-ups and
changeover instructions (see Fig. 14.5.2), or else these can be output to the printer.
A request for set-up changeover can be initiated as follows:
-
by the station controller, for the particular station it controls, at the moment changeover is actually to
be performed at the station.
-
by the operator via the user interface of the Set-up Modification Generator, for the entire line, at any
time.
-
by the Data Manager for the entire line, at any time.
14.5.1 Terms Used in the Connection With Set-Ups (Set-Up Types)
• Initial Set-Up
This refers to the set-up from which the changeover procedure originates.
In the case of changeover requests released by the station controller or the Data Manager the initial
set-up is always the current set-up of the station or the line.
• Follow-Up Set-Up
This refers to the set-up of a line or a station that is to be the result of the changeover procedure. The
follow-up set-up can be a set-up already existing or one to be newly created by the Set-Up Modification
Generator for the production of a specific PCB type.
• Target Set-Up
This is an existing set-up for a given PCB.
When a follow-up set-up for this PCB type is to be created, the target set-up specifies where the
components are to be set up that are not contained in the initial set-up. All components required for the
production of the PCB type must be contained in the target set-up.
• Changeover Instructions
They describe the changeover from an intitial set-up to a follow-up set-up.

Four different possibilities to carry out the changeover exist:
1. Current set-up ---> Set-up
The initial set-up is the current set-up.
For this purpose changeover instructions are created and output on the screen or to a printer.
2. Current set-up ---> PCB-specific set-up
The initial set-up is the current set-up, the follow-up set-up is to be newly created.
A set-up changeover is to be carried out for the production of a given PCB type. The predetermined target
set-up specifies where the components that are required in addition to the current set-up should be
positioned. The Set-Up Modification Generator generates a follow-up set-up on the basis of the current set-
up, the target set-up and the description of the PCB type. The follow-up set-up is transferred to the master
data storage.
Set-up changeover instructions are drawn up in addition.
3. Set-up ---> Set-up
The operator or the requesting program specifies the initial and follow-up set-ups, both existing in the
master data storage.
Set-up instructions are then created and output on the screen or to the printer.
4. Set-up ---> PCB-specific set-up
The operator or the requesting program specifies the initial set-up, the target set-up and the PCB type.
A follow-up set-up is created and stored in the master data files.
Set-up changeover instructions are created and output on the screen or to the printer.
☞
NOTE
All four types of changeover possibilities can be initiated by operator input or the requesting program.
The Data Manager can request changeover for possibilities 1 and 2 only. The station controllers can only
request set-up changeover related to the first possibility.
