2.2 EDM Configuration Manager

The EDM Configuration Manager is the central location for configuring the EDM system. There, you

will find 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 location

Based on certain rules, the Configuration Manager assigns exactly one configuration set to each

EDM computer, defining its behavior.

The configuration options and the user interface are described in section 5.3.

2.3 EDM Master Server

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.

2.4 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 customer

needs (see section 6.4, Workflow Configuration).

2.5 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.

2.6 EDM Data Transfer Manager

The data preparation engineer controls the push mode functions using the EDM Data Transfer GUI

(see section 3.2 Push mode). 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.

2.7 EDM notifications

The EDM Service converts the change notifications received from the lines into a human-readable

form and distributes these to the appropriate locations. The type of messages sent and the

recipients of the messages can be configured. This will be explained in more detail later on (see

section 5.3.7, Notifications/Rules…).

2.8 EDM Line Server

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.

2.9 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 6.3.6.14 EDM tool endpoint).

As a singleton, the EDM Tool only runs in one user session a time, i.e. on server operating systems

only one user, who is logged in, will be able to run the EM Tool.

3 Data transfer

SIPLACE EDM was developed to make it possible to store SIPLACE Pro data on a decentralized

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

3.1 Pull mode

On the one hand, the pull mode represents a stand-alone process controller for the data transfer,

and on the other hand, it serves as basis for the forced pull mode. For this reason, this section will

only deal with the aspects common to both modes, and the following section will only deal with the

aspects specific to the forced pull mode.

The basic idea behind the forced pull mode as well as the "simple" pull mode is that the line

engineer is responsible for the production data and for the decision regarding which data applies to

the line since the line engineer is responsible for ensuring that the line produces.

To do this, the line engineer manually starts the pull mode via the SIPLACE EDM Client. He or

she selects the data to be transferred. The data preparation engineer, though, is provided with

configuration options he or she can use to actively intervene in the process (see section 5.3.6,

Application templates). The data preparation engineer specifies what objects are available for each

line and what object types are to be overwritten when performing a download to the line. In general

terms:

– The data preparation engineer is responsible for the correctness of the object types overwritten

during the download.

– The line engineer is responsible for the object types that are not overwritten.

The data preparation engineer, however, has neither influence on whether or not the line engineer

pulls new data from the Master Server, nor when this data is pulled.

3.2 Push mode

In push mode, the data preparation engineer selects the data he or she wishes to make available

to the lines they are responsible for. They use an application template (see section 5.3.6) to

select one or more line computers and the objects (e.g. optimized recipes) that they want to

transfer to the selected line(s). Depending on the settings in the configuration, the line engineer is

forced to accept these changes immediately or later, may reject them, or is simply notified that data

has been changed. With the EDM Data Transfer Manager, the data preparation engineer always

has an overview of the status of the individual transfer packages on the EDM lines.
