Application
8.1.1 General rules
In general the following applies to the 7-segment display (on CPU-
modules):
 Numbers >0 during the start-up denote the progress
 Different characters (e.g. , II, ...) or capital letters denote the operating
status after start-up
 The decimal point serves as load display. A flashing decimal point
signals that the CPU’s load capacity is not fully exhausted.
 Errors are displayed parallel to the states.
 The error display is always triggered with switching-through the status
and a double- or triple-digit error/info sequence (e.g. “-,0,-,E,1,0”). Every
character is displayed for 1 second.
8.1.2 Touch control during operation:
The CTRL key serves as simple operating element of the control. With this
key the control can be switched into different operating modes and/or dif-
ferent commands can be issued.
 There are short (<500ms) and long keystrokes (>500ms).
 Short keystrokes allow the user to switch and select between the indi-
vidual commands, while these commands are displayed by flashing in
the 7-segment display. Once the initial status has been reached again
this will be indicated without flashing.
 Long keystrokes are used to execute a command and to change into
the new status.
