Caution
!
Note regarding TP
Do not touch the screen of the Touch Panel until after the initialization phase
start–up
when the menu illustrated in figure13-2 or figure 13-3 appears.
The signal tone is not active during startup.
13-2
With the SIMATIC S5, compression of the internal program memory on
the PLC (PU "Compress" function, integrated FB COMPR) is not allowed
when a Touch Panel is connected. Compression modifies the absolute ad-
dresses of the blocks in the program memory. As the Touch Panel reads the
address list only during startup, it does not detect any address modifica-
tions and accesses the wrong memory areas.
If compression is inevitable during routine operation, switch off the Touch
Panel prior to compression.
In hazardous areas, always de–energize the Touch Panel before unplugging
connectors.
