35 Select Controllers
Protected PLC-5 Controllers
The Protected PLC-5 controller lets you limit access to critical or proprietary
areas of programs, selectively guard controller memory and I/O, or restrict use
of controller operations. The distinctive safety-yellow labels on the controller
identify the protected PLC-5
controller.
Use the programming software to assign class privileges to specific user
accounts or a user’s job function, such as system administrator, plant engineer,
maintenance engineer, or operator. Using four privilege classes and associated
passwords, you can limit access to critical areas of programs and restrict access
to:
communication channels.
remote nodes attached to the ControlNet or DH+ network.
program files.
data files.
The protected PLC-5 controller expands system validity and security beyond
that provided by the password-and-privilege feature of the other PLC-5
controllers. The Rockwell Automation clutch/brake application package
combines the protected PLC-5 controller with specially-designed software to
support stamping press applications
