3.2 Saving the data
Basically the communication programs/devices that have been referred to only change the
parameters in the volatile memory of the control unit. Although the control unit will
immediately operate with the new settings, any values changed in this way will be lost
when the voltage supply is turned off. A storage command must be used to permanently
save the parameter settings in the control unit. DcDesk 2000 uses the function key F6 for
this, while the hand programmers work with the “Save Parameter” key or menu option. It
is this operation that is meant whenever there is a reference to the need to save parameters
in the following descriptions.
3.3 DcDesk 2000
The HEINZMANN DcDesk 2000 PC program is used to set up and distribute operating
data in all digital HEINZMANN systems, in particular the systems described here.
The PC and the control unit are connected by a serial interface. A remote communication
variant allows “extended” access over the Internet, Intranet or by direct modem
connection.
As a Windows
®
program it offers all of the numerical and graphic features that are needed
for experimental work, first commissioning and servicing, and facilitates the associated
documentation work.
DcDesk 2000 also allows the user to print off screen displays and data recordings. The data
are stored in a standard text format for the purposes of further processing, importing into
reports etc.
The data record of a connected control unit can be edited and the response to parameter
changes can be observed at the same time. A parameter set can also be edited and recorded
data can be evaluated without a control unit. A parameter set that is created in this way can
be transferred to the control unit later on.
All settings can be made directly by accessing parameter numbers. However there are also
additional windows which can significantly simplify special functions, especially
configuring the system and parameterizing curves.
Current measured values are displayed numerically and/or graphically. There is a separate
window in which up to ten freely selectable measured values can be displayed
simultaneously as a function of time. There is another window in which nine measured
values can be displayed as a function of a tenth. Data recordings can also be logged for
analysis and printing at a later time.
All of the curves that are available in the control unit can be shown in separate windows
two-dimensionally. This can provide an immediate impression of the curve profile. The
current point where the system is on the curve is displayed online. A knowledge of the
relationship between the parameter number and the point on the curve is not necessary for
