Display Of The Cpu - Siemens SIMATIC S7-1500 System Manual

Display of the CPU

The section below gives an overview of the mode of operation of the CPU display. Detailed
information on the individual options, a training course and a simulation of the selectable
menu items is available in the SIMATIC S7-1500 Display Simulator
(http://www.automation.siemens.com/salesmaterial-as/interactive-manuals/getting-
started_simatic-s7-1500/disp_tool/start_en.html).
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 diagnostics alarms in plain text
● Changing of the interface settings on site without programming device
● Password assignment for display operation is possible via STEP 7
● Shorter downtimes due to read access to watch and force tables.
● IP addresses of CPU and connected CP/CMs are adjustable
Operating temperature for the display
To increase the service life of the display, the display switches off when the permitted
operating temperature is exceeded. 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.

This allows the current values of the individual tags of a user program or a CPU to be
monitored by the watch and force tables. You can find additional information on the watch
and force tables in the section Test functions and fault correction (Page 143) and in the
STEP 7 online help.
