2.2.1 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 5.1.6). 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.
2.2.2 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 5.1.6) 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.
In contrast to the two pull mode variants, the data preparation engineer has the sovereignty over
the status of the data in push mode.
Push mode and pull mode may be used independently. EDM can be operated in mixed mode
without problems.
To perform a push operation the EDM Data Transfer Manager (Push Mode) needs network access
to the Line Servers receiving the data.
2.2.3 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 period. If no data is downloaded from the Master Server during the
time 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.
NOTICE
However, the push mode would probably support this use case better than the forced
pull mode.

3 Starting And Terminating SIPLACE EDM
3.1 Starting SIPLACE EDM
The EDM Master and Client services are implemented as Windows services that start automatically
when the system is started.
The single EDM components can be started in the following ways:
► Start the desired EDM component from the Windows® Start menu under Programs –
SIPLACE EDM.
Or
► Double-click on the icon of the desired EDM component on the desktop.
The following icons are available on the desktop in order to run the single EDM components:
EDM Client
EDM Clearing Pool
EDM Configuration
EDM-Data Transfer Manager (push mode)
EDM Tool
3.2 Terminating SIPLACE EDM
The EDM services terminate automatically when the system is terminated.
The single EDM components can be terminated in the following ways:
► Terminate the EDM component via the File – Close tab.
Or
► Click on the cross in the upper edge to the right in the EDM component view.

EDM will block a shutdown / system reboot in the following cases:
– a Comment dialog is displayed
– the configuration has unsaved changes
– the Clearing Pool is performing a push, merge, accept or reject operation
3.3 Restarting the EDM Services
The EDM Tool provides a Restart EDM Service command. The user access control (UAC) facility
introduced in Windows Vista requests administrators with restricted access to grant enhanced
permissions before the service is restarted by the operating system. A regular user has the option
of logging in as an administrator temporarily to restart the EDM service.
