CPU display

Introduction
The following section gives an overview of how the R/H-CPU display operates. 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
(https://support.industry.siemens.com/cs/ww/en/view/109761758).
Display
The R/H-CPUs have a front cover with a display and operating keys. The display of the CPUs
shows you the control and status information in various menus. You use operating keys to
navigate through the menus and make a variety of settings in the process.
Benefits
The display offers the following advantages:
• Reduced downtimes through diagnostic messages in plain text
• Less time required for commissioning and maintenance, shorter plant downtime.
• Shorter downtimes due to read/write access to force tables and read/write access to watch
tables.
The watch and force tables allow you to monitor and modify the actual values of
individual tags of a user program on the display. You can find additional information on
the watch and force tables in the section Test and service functions (Page 344) and in the
STEP 7 online help.
• Visualization of the SYNCUP system state with graphic and percentage progress display
• Overview of status of safety mode and of F-parameters of integrated F-CPU
Password protection for the display
In the properties of the CPUs, you configure a password in STEP 7 for display operation. Local
access protection is thus protected with a local password. Password protection can be
configured differently for each display.
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
