Introduction
The S7-1500 CPU has a front cover with a display and operating keys. Control data and
status data can be displayed in various menus on the display, and numerous settings can be
configured. You use the operating keys to navigate through the menus.
Benefits
The display of the CPU offers the following advantages:
● Reduced downtimes through diagnostic messages in plain text
● Changing of the interface settings on site without programming device
● Password assignment for display operation is possible through the TIA Portal
Operating temperature for the display
In order to increase the service life of the display, the display switches off before the
permissible operating temperature is reached. When the display has cooled down again, it
switches on automatically again. The status of the CPU continues to be indicated via the
LEDs while the display is switched off.
Further information about the temperatures at which the display switches off and back on
again is available in the technical data of the manuals of the CPUs.
