BE1-951 ASCII
Command
Interface
11-3
ASCII Command Examples
1.
Obtain a breaker operations count by entering RB (Report Breaker). The BE1-951 responds with the
operations counter value along with all other breaker report objects. If you know that the object name
for the breaker operations counter is OPCNTR, you can enter RB-OPCNTR and read only the number
of breaker operations.
Partial object names are also supported. This allows multiple objects to be read or reset at the same time.
2.
Read all peak-since-reset demand current registers. Entering RD-PI (Report Demand - Peak Current
(I) will return demand values and time stamps for phase A, B, C, Neutral, and Negative Sequence
current. To read only the Neutral demand value, the full object name (RD-PIN) is entered. Entering RD-
PI=0 resets all five of the peak-since-reset current demand registers.
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.
1.
//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
Obtaining Help Information
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 with command information.
Syntax:
HELP[x/<cmd>]
Changing Settings
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.
