Protect your system from unauthorised physical access. Use a lockable
control cabinet, for example.
NOTICE
Unauthorized deletion/replacement of the safety-related project possible

Only provide the roles for user authentication “Admin”, “Commissioner”,
and “Engineer” to those users who are authorized to program the safety-

‘User Authentication’...page 200
−
It is imperative that you install the CPU and the modules in a row in
a lockable housing or a lockable control cabinet. The device housing is
not protected against manipulation and access to the CPU cannot be
validated. Access to the SD card is possible so that data can be read and
manipulated. We recommend protecting the slot of the parametrization
memory (SD card) on the CPU against manipulation with a seal.
