11.8 Protection by locking the CPU

11.8 Protection by locking the CPU
Locking options
Provide additional protection for your CPUs from unauthorized access (for example to the
SIMATIC Memory Card) by using a secure cover.
You have the following options, for example:
• Attach a seal
• Secure the cover with a lock (shackle diameter: 3 mm)
①
Note
Protection with a seal or padlock only prevents "easy" access to the SIMATIC memory card and
operator controls. It does not provide protection from targeted tampering; this must be
ensured with other measures (for example through the control cabinet).
