3.2.6.3 Protocol write access rights
Write access rights are configurable for FTP, MMS, and HTTPS protocols in
Configuration> Authorization. The write access parameters are used to narrow
down services that allow setting changes on different network interfaces. Disabling
the FTP and IEC 61850 MMS write access on Network 1 and 2 prevents the user
from updating the configuration to the protection relay from PCM600. Disabling the
HTTPS write access prevents the user from writing setting changes from WHMI.
