9328900990 Rev L BE1-951 ASCII Command Interface 11-3
Command Text File Operations
In command text file operations, an ASCII text file of commands is created and sent to the relay. For
example, the S command is used to retrieve a complete list of settings from the relay in ASCII command
format. This list of commands is captured, saved to a file, edited with any ASCII text editor, and then
uploaded to the relay. Because the number of relay settings is so large, loading settings with a text file is
the preferred method of setting the BE1-951.
Embedding Comments into ASCII Text Files
Adding comments to ASCII settings files is an easy way to organize and label your settings. A comment
line is started with two forward slashes (//) followed by the comment text. When the relay encounters // in
a text file, it ignores all following characters until the next carriage return or linefeed character.
Example of embedding comments in a settings file:
//Group0 is used during normal operation
>S0-50TP=7.50,0m;S0-50TN=2.5,0m . . .
//Group1 is used during cold load pickup
>S1-50TP=0,0m; S1-50TN=0,0m; S1-50TQ=0,0m
Miscellaneous Command Descriptions
HELP Command
The HELP (H) command provides general information on command syntax and functionality when the
manual is not available. Entering HELP or H provides information about using the HELP command.
HELP1 or H1 returns a complete list of relay commands. Entering HELP <cmd>, where <cmd> is a
specific command, returns information about the use and format of the command along with an example
of how the command is used.
HELP Command
Purpose: Obtain help on command operation
Syntax: HELP {cmd} or H {cmd} for help on {cmd}, H1 for command list
Example: HELP, H1, H SG-COM
ACCESS Command
Before making settings changes through a communication port, the ACCESS command must be used to
obtain programming access. Enter ACCESS=<password> to obtain access to change settings associated
with the password. Different passwords give the ability or access to perform different operations. The
relay will deny access if an invalid password is entered or if another user has already been granted
programming access through another serial port or at the front panel. Only one user can have access at
any one time.
Even if password protection is not used, it is still necessary to obtain access so that accidental changes
are prevented. If password protection is disabled, then ACCESS= will be accepted in place of a
password. The relay will respond with ACCESS GRANTED: GLOBAL if the command entered was
received and executed. The relay will respond with an error message and a ‘?’ if the command could not
be executed.
The ACCESS (A) command and the EXIT (E) command are used to change relay settings, reset report
registers, and enable control commands through a serial port. These commands prevent changes from
being made concurrently from two areas. For example, a user cannot make changes through COM0 at
the same time a remote user is making changes through COM2.
ACCESS Command
Purpose: Read/Set Access level in order to change settings
Syntax: ACCESS[={password}]
Example: ACCESS=951
Comments: The ACCESS command must be used before any changes to settings can be made.
Available ACCESS privileges are summarized in the following paragraphs.
