5.0 FUNCTIONAL DESCRIPTION

5.1 Passwords

The M87x has implemented the standard Bitronics password scheme. There are three
different access levels:
Level 0: This access level provides read-only access to all settings and data, thus
preventing modification of information that affects system security. The factory default
password for level 0 is "AAAA"; this is the same as entering no password.
Level 1: This access level includes the read access of level 0. In addition, the user is
permitted to delete recorder files, and reset energy and demand values. The factory
default password for level 1 is "AAAA"; this is the same as entering no password.
Level 2: This access level includes all lower level functionality. The user is also granted
full read/write/delete access on all files in the M87x, including the configuration files. The
factory default password for level 2 is "AAAA"; this is the same as entering no password.
NOTE: The factory default is to allow level 2 access with no password. For the password
scheme to take effect, the user must change the passwords with the 70 Series
Configurator.

5.2 Configuration

Setup of the M87x is most easily performed using the 70 Series Configurator. This
software runs on a PC and allows the PC to communicate to the M87x using a serial port
or Ethernet connection. The M87x configuration is stored internally by means of several
configuration files, located in the directory shown in the following table. Most of these are
ASCII text files, and may be saved, copied, and deleted by any of the various methods of
file manipulation, such as FTP, Zmodem, and the 70 Series Configurator.
If using IEC61850 protocol, the configuration of the IP and SNTP addresses will be
determined based upon a selection the user makes by way of the radio button selections
found on the 70 Series Configurator Identity page. The radio buttons provide the user with
the flexibility to decide which software tool will control the IP and SNTP address
configuration settings. Configuration settings are loaded upon reboot from either the
Initialization (INI) files or the Micom Configuration Language (MCL) files, depending upon
the radio button selected during configuration. The IP and SNTP addresses will be loaded
either from the respective address settings stored in the INI file by the 70 Series
Configurator or from the address settings stored in the MCL file by the IEC61850 IED
Configurator. Addresses written into the MCL file will be written back into the INI file when
the unit reboots. It is only possible to synchronize the addresses by reading the address
information written into the MCL file back into the INI file upon reboot. (The IP and SNTP
Addresses are rewritten to the INI file though the 70Series Configurator upon reboot since
the IEC61850 IED Configurator does not have the ability to rewrite information once the
configuration is written to the MCL file). There is a mechanism to automatically sychronize
these addresses upon rebooting the M87x, so that the current IP address for the M87x will
be updated on the 70 Series Configurator Identity page. For the case when the radio
button is selected as "IEC61850 IED Configurator (MCL file)" the IP networking information
