2 SIPLACE EDM Overview
The Engineering Data Manager comprises three major units: the EDM Configuration Manager,
EDM Master Server and the EDM Client. The illustrations below show a basic deployment scenario
and a typical deployment scenario for the EDM and the communication paths between the
individual system components.

2.1 System Components
The Engineering Data Manager consists of the following system components.
2.1.1 EDM Configuration Manager
The EDM Configuration Manager is the central program for configuring the EDM system. Changing
the EDM configuration is an administrative task and does not concern the EDM line operator.
The EDM Configuration Manager contains the functionality to define and change configuration sets
to support multiple EDM scenarios. A configuration set consists of references to all configuration
items, including
● Filter rule settings
● Settings for email notification on incoming notifications
● Master server storage location
Based on certain rules, the Configuration Manager assigns exactly one configuration set to each
EDM Client computer, defining its behavior.
The configuration options and the user interface are described in chapter 5.
2.1.2 EDM Master Service
The EDM master service is the server component of EDM. It replies to queries from EDM line
services and distributes the data in the central SIPLACE Pro database among the lines. In return, it
accepts change notifications and collects them in the Clearing Pool database.
The EDM master service is implemented as a Windows service that starts automatically when the
system is started.
2.1.3 EDM Line Service
The EDM line service is the counterpart to the EDM master service. It monitors the changes made
by users to the local SIPLACE Pro data (SPI), documents the changes and sends them to the
master service for entry in the EDM Clearing Pool.
2.1.4 EDM Client
The EDM Client enables user interaction on the line. It implements the customer workflow for the
distribution of data from a central database. The workflow can be customized to match user needs.
See section 4.2 and section 6.3.
2.1.5 EDM Clearing Pool
The EDM Clearing Pool is the tool used by the data preparation engineer to examine the change
notifications from each of the lines in terms of their relevance and, if necessary, integrate them into
the SIPLACE Pro master database. With the functionality already available in SIPLACE Pro,
individual objects of a certain type (components, component shapes, fiducial types, boards and
placement lists) can be compared attribute-by-attribute, and changes can be applied at this low
level. The EDM Clearing Pool can be installed on a separate workstation computer independently
of the EDM master service. See section 4.4.

2.1.6 EDM Data Transfer Manager (Push Mode)
The data preparation engineer controls the push mode functions using the EDM Data Transfer GUI
(see section 2.2.2). Here, the objects to be sent are selected and sent to the relevant lines, a status
display shows the progress of the data transferred in this way, informs the user that the push
operation was successful and warns of any problems.
The EDM Data Transfer Manager usually is installed in combination with the EDM Clearing Pool,
but may also be setup on another computer that provides network access to the EDM Master and
all EDM Lines.
2.1.7 EDM Tool
The EDM Tool is a utility that runs on all EDM computers and that monitors the status of the EDM
services (master service and line service) and the integrity of the EDM configuration files.
It also allows you to enter comments for new notifications on the Line Server.
Comments can also be entered on a computer other than the Line Server. To do this, the EDM
Tool must be installed on this computer and an entry in the configuration file of the Line Server
must be adapted accordingly (see section 6.2.6.14).
As a singleton, the EDM Tool only runs in one user session a time, i.e. on server operating systems
only one user (the first one), who is logged in, will be able to run the EDM Tool.
2.2 Data Transfer
SIPLACE EDM was developed to make it possible to store SIPLACE Pro data on a centralized
basis. One requirement to reach this goal is to guarantee an efficient, selective data transfer from
the Master Server to the Line Servers and in the opposite direction. Changes made at the local
level are integrated into the central database so that it contains data that is valid – i.e. as up-to-date
as possible – throughout production.
From a technical point of view, the bi-directional data transfer rests on the data import and export
functionality of SIPLACE Pro, which is also available from SIPLACE Pro Desk.
SIPLACE EDM implements a process-based solution for data transfer. The program provides three
approaches to control and monitor the data flow:
● pull mode
● push mode
● forced pull mode
