16.1 Introduction
Apart from technical malfunctions occurring in SMD production, mainly problems originating in the organizational
environment are likely to arise. These frequently result from missing components, inadequate information flow
and imbalances in the workload on the stations of a line. Prerequisite for the efficient elimination of these weak
spots is a profound knowledge of their underlying causes which can only be determined through continuous
automatic monitoring of the system.
The Ma
chine Data Management System (MaDaMaS) collects all relevant data of the line and offers the
possibility of a graphical representation of the production line status. It is thus possible - as soon as a PCB has
exited the line - to obtain a current display of the operational status of a complete line or individual stations.
This allows the user to swiftly take appropriate corrective action in the case of malfunctions, errors or
imbalances.
The present MaDaMaS version allows all logged production data to be evaluated taking one of the following
three time intervals (time base) as the basis:
- Evaluation from the time of the last set-up changeover to the present
- Evaluation from the time of the last PCB type changeover to the present
- Evaluation from the time of the last reset to the present
The evaluated data allow assessments to be made related to the following subject areas:
- placement performance (track errors, "good" placements)
- breakdown of the total processing time of a PCB into different status classes
(running, waiting, blocked, interrupted, failed)
- logging of automatically detected malfunctions
Each station automatically collects all data of "good" placements as well as track errors occurring during the
assembly of a PCB. Moreover, specific machine states are recorded with the aid of time meters.

16.1.1 Definition of the Times Collected by the Station
The station captures data both on malfunctions and normal machine statuses. Since several events can occur
simultaneously, priorities are assigned to the individual events. The events are classified into 4 groups with
group 4 having the highest and group 1 the lowest priority.
16.1.1.1 Type of Events
The events are recorded and then displayed on the MaDaMaS evaluation user interface (see section 16.2.8.5)
under the terms (causes) explained in the following description of the individual groups.
Group 1 Interruptions:
This group contains all shutdown causes logged on the machine that resulted from operator interven-
tion.
Within group 1 the malfunction occurring first is always given top priority. As long as this malfunction
is not eliminated (by pressing the Start button or Continue placement), any subsequently occurring
malfunctions are not taken into account.
Type of event: Status:
Abort button actuated Interrupted
Single function / Vision Menu Interrupted
Stop button actuated InterruptedI
Emergency stop actuated / compressed air failure Interrupted
Step mode active Interrupted
Protective cover open Interrupted
Waiting for Start button Interrupted
Waiting for Control ON Interrupted
Waiting for protective cover to be closed Interrupted
Group 2 Machine States During Normal Operation:
This group contains all states the machine is able to assume during a normal placement (glueing) cycle.
Within group 2 the status is given highest priority that has been assumed last. The currently active
status is thus terminated.
Type of event: Status:
Data supply Waiting
Waiting for PCB in input conveyor Waiting
Waiting for PCB in center conveyor Waiting
Wait until output conveyor/center conveyor is clear Blocked
Placement / glueing Running

Group 3 Machine Malfunction:
This group contains all shutdown causes that resulted from malfunctions within the machine.
Within group 3 the malfunction is given highest priority that has occurred last. The currently active
malfunction is thus terminated.
Type of event: Status:
Cartridge 1 empty Failed
Cartridge 2 empty Failed
Cartridge 3 empty Failed
Unidentified error Failed
General machine malfunction Failed
Barcode reading error Failed
No assigned cause Failed
Fiducial error Failed
Track error Failed
Transport error Failed
Replacement of glue wiping roll Failed
Group 4 Setting-Up Mode:
This group comprises all machine states that can be assumed by the activation of special functions
through the operator.
Within group 4 the status is given highest priority that is signalled last. Any currently active malfunction
is thus interrupted although not terminated. A group 4 status can only be terminated by the respective
end message (e.g. in the case of state "Single function / Vision Menu" by exiting from the Vision Menu).
Type of event: Status:
Cycle mode active Interrupted
Keyswitch in SLOW position Interrupted
Single function / Vision Menu (Teach-in) Interrupted
Single function / Vision Menu (Single functions) Interrupted
NOTE
All times of incidents are evaluated that occurred in a given group.
If, for example, an event associated to group 3 has occurred and if subsequently a group 4 event is
encountered due to changeover to Single Functions, the time from the first occurrence of the group 3
event up to the transition to group 4 is attributed to the particular event of group 3.
