FTP and HTTP protocols are not secure. Ensure general security in the
substation is considered as described in General security deployment
guidelines.
FTP and HTTP are always enabled and cannot be disabled.
For the FTP protocol, it is strongly recommended to change the
default password using IED Users Management in PCM600 as
described in the communication configuration manual. The default
password in RIO600 for the ADMINISTRATOR user credential is
“ABB_RIO600”==/”.
RIO600 supports only one user credential for ADMINISTRATOR.
Modbus is disabled by default and can be enabled with Parameter
Settings in PCM600. In the plant structure, go to RIO600/IED
Configuration/Configuration/Station Communication/
MODBUS: 0 to set the Modbus configuration parameters.
