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 and
• 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 discuss
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 selects the
data to be transferred. The data preparation engineer, though, is provided with configuration options he
can use to actively intervene in the process (the application templates, see also 5.4). 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, and the line engineer is responsible
for the object types that are not overwritten.
The data preparation engineer, however, has no 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 one 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.

3.3 Push mode
In push mode, the data preparation engineer selects the data they wish to make available to the lines they
are responsible for. Under a graphical user interface, they use an application template (Section 5.4.1) to
select one or more line 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, or can reject them, or is simply informed of the receipt of changed data. 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, sovereignty over the status of the data in push mode lies largely
with the data preparation engineer.
Push mode and pull mode should be used independently. EDM can be operated in mixed mode without
problems.
