Displays and operating elements
4.1
Diagnosis display (DIAG)
A single-digit 7-segment display on the front side of the CPU modules indi-
cates the start-up and operating modes.
Fig. 4-8: 7-segment display
The following applies in general for the 7-segment display:
●
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 sig-
nals that the CPU load is in the allowed range. If the decimal point stops
blinking, then the CPU is overloaded and correct operation is no longer
guaranteed.
●
Errors are displayed parallel to the states.
For further information see chapter "Diagnosis".
