Basic Configuration
5.4.3. Port Access
The Port Access parameter can be used to grant connection access to the MPC's DB-9
Console port, RJ-45 Remote port and RJ-45 AUX ports. Normally, the Console port
is used for connection to a local control device such as a laptop, the Remote port is
used for connection to the optional MPC-DISPLAY unit, and the AUX ports are used
for connection to additional remote MPC or BPM units. However, if your application
requires communication with other devices in the equipment rack the Console port,
Remote port and AUX ports can also be used for connection to these devices.
Administrator and SuperUser level accounts are always allowed access to the Console
Port, and User level accounts can always be granted access to the Console port. Note
however, that in order to allow an account to access the AUX ports and Remote port,
these ports must first be reconfigured as serial ports as described in Section 5.8.2.
When the AUX ports and Remote port are left in their default configuration, accounts will
not be allowed to create connections to these ports.
In addition, the command access level will also determine which ports the account will
be allowed to access, as summarized below:
• Administrator and SuperUser: Accounts with Administrator or SuperUser level
command access are always allowed to connect to the Console Port. If the AUX
and Remote ports are configured as serial ports, then Administrator and SuperUser
level accounts will also be allowed to connect to these ports. Port access cannot
be disabled for Administrator and SuperUser level accounts.
• User: User level accounts are only allowed to connect to the Console Port when
port access has been specifically enabled for the account. If the AUX and Remote
ports are configured as serial ports, then User level accounts can also be granted
access to these ports.
• ViewOnly: Accounts with ViewOnly access are not allowed to create connections
to the serial ports.
