Siemens SIMATIC S7-1500/ET 200MP System Manual page 292

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.
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.
Note
The S7-1500 CPU has no internal temperature measurement. Reading out the internal
temperature of the S7-1500 CPU is not supported.
