Cpu Display - Siemens SIMATIC S7-1500 System Manual

CPU display

Introduction
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).
Display
The S7-1500 CPU has a front cover with a display and operating keys. The display of the
CPU shows you the control and status information in different menus. You use operating
keys to navigate through the menus and make a variety of settings in the process.
Benefits
The display of the CPU offers the following advantages:
● Reduced downtimes through diagnostic messages in plain text
● Changing of the interface settings locally without a programming device
● Password assignment for display operation is possible via STEP 7.
● Shorter downtimes due to read and write access to force tables and read access to watch
tables:
The watch tables and force tables allow the current values of the individual tags of a user
program or CPU to be monitored and modified on the display. You can find additional
information on the watch and force tables in the section Test functions and fault
resolution (Page 225) and in the STEP 7 online help.
● IP addresses of CPU and connected CMs/CPs can be set.
● For F-CPUs: Overview of status of safety mode and of F-parameters of F-CPU and F-I/O.
● Backing up/restoring the CPU configuration to/from the SIMATIC memory card.
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. When the display is switched off, the LEDs continue to show the status
of the CPU.
Additional 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.
