General Settings
The adjustment of set points and the selection of an operation mode are performed via console ( Front Panel
Operation), interface ( Universal Interface) or analog/digital IO ( Ext. Control: AI-Interface).
In order of priority, commands which have been sent by interface come first, by analog/digital-IO come second and by
keyboard come third. For example, if the interface specifies the set point, the corresponding values will be sent to the
output, irrespective of other settings.
Another easy way to automate functions is offered by script control ( Script Control). A list of commands is saved to
the script memory and enables the user to change the chronological sequence of certain settings. The script memory
can be programmed via memory card or digital interface.
Measurement values of the latest output data are permanently available at all interfaces. Therefore, the present
output voltage can be read from the display or via digital interface, while the control of the unit is carried out via
analog/digital IO.
