Ladder Memory Protection
A memory protection dipswitch provides protection for the RLL program. When
the switch is in the ON position, the program cannot be changed by a
programming device that is connected to the PLC through one of the
communication ports.
NOTE
The memory protection dipswitch does not prevent forcing I/O,
changing variable memory, or switching the PLC from PROGRAM
to RUN mode. These actions may be made by a programming
device connected to the PLC, or a special function I/O module
designed for this type of interface to the PLC, e.g., a Network
Interface Module. The RLL can also be changed through a special
function module, even when the memory protection is enabled.
