EDM V1.10 / Installation Manual 07/2011 Edition

2.2 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.

2.3 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 5.2.4 Configuring push mode). The workflow to be performed here is to be

obtained from the customer, discussed with the customer, and customized for technical or

efficiency reasons if necessary before installing the EDM system.

2.4 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 independently of the EDM master service on a

separate workstation computer.

2.5 EDM Data Transfer Manager

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

(see section 3.3 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 is always installed in combination with the EDM Clearing Pool.

2.6 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 5.4 EDM configuration and section 5.5 Filter configuration).

2.7 EDM configuration

The EDM configuration is the central location for configuring the customized settings. There you

will find the functionality to

● create and administer application templates

● configure email notifications on incoming notifications

The configuration options and the user interface are described in sections 5.4.1 Application

templates and 5.4.2 Email configuration.

2.8 EDM filter configuration

EDM filter configuration allows you to configure the EDM notifications. The configuration options

and the user interface are described in section 5.5, Filter configuration.

2.9 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 database, documents the changes and sends them to the

master service for entry in the EDM Clearing Pool.

2.10 EDM Tool

The EDM Tool is a utility that runs on the Master Server and Line Servers and which 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. The EDM Tool is installed 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 5.2.3.14 EDM tool endpoint).

3 Data transfer

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

basis. One requirement to fulfill 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, bi-directional data transfer is based on the import and export data

model in SIPLACE Pro, which is also familiar from SIPLACE Pro Desk and which can be performed

manually from the Desk.

SIPLACE EDM implements a process-based solution for data transfer. The program provides three

approaches to controlling and monitoring the data flow:

● pull mode

● forced pull mode

● push 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 the 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 basically 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 5.4.1

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 Forced pull mode

With forced pull mode, SIPLACE EDM provides an option of ensuring that the line data engineer

is always working with relatively up-to-date data. This mode allows for the specification of a

maximum time period between two downloads. This should ensure that the data on the lines is

never older than the prescribed time period. If no data is downloaded from the Master Server

during the time period defined, then the data preparation engineer is informed of this via a

SIPLACE EDM notification and can initiate organizational activities to ensure the data is

downloaded and up-to-date.
