Protection By Locking The Cpu - Siemens SIMATIC S7-1500 System Manual

9.6

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 front cover.
You have the following options, for example:
● Attach a seal
● Secure the front 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).
