Protection
8–21
REMote Position
While you are in the REM position, you can change the mode using a programming
device. Online editing is allowed while in the REM Run, REM Program, and REM
test mode.
Communication Channel Protection
(SLC 5/03 and SLC 5/04 Processors)
Use this type of protection to designate one channel as programming and the other
as monitoring. Either channel may be protected, but not both. When a channel is
protected, the following functions are not available from the affected channel:
•
change mode
•
force
•
open/close a file
•
set program owner
•
clear memory
•
downloading
•
writing user data or user program
•
channel configuration
Channel protection is selectable using the channel configuration menus. Both
channels should have their protection cleared prior to enabling channel protection.
Do not apply protection to the channel you are currently communicating
through unless you: 1) never intend to alter the program again, or 2) can
establish communications using the other channel.
Channel protection is permanent.
