can contain four digits. The digits are supplied one by one by

Password Handling
The passwords can only be changed using SetPointPS software
connected to the local RS-232 port on the relay.
It is possible to restore the password(s) in case the password is lost or
forgotten. In order to restore the password(s), a relay program is
needed. The serial port settings are 38400 bps, 8 data bits, no parity
and one stop bit. The bit rate is configurable via the front panel.
Command Description
get pwd_break Get the break code (Example: 6569403)
get serno Get the serial number of the relay (Example: 12345)
Send both the numbers to Rockwell Automation and ask for a
password break. A device specific break code is sent back to you.
That code will be valid for the next two weeks only for this specific
device.
Command Description
set pwd_break=4435876 Restore the factory default passwords (“4435876” is
just an example. The actual code should be
requested from Rockwell Automation.)
Now the passwords are restored to the default values (See section
“Operating Levels”).
