General command functions are organized into five major groups plus one group of miscellaneous

commands. These groups are listed below:
CONTROL (C):

Control commands perform select-before-operate control actions such as circuit

breaker tripping and closing and active setting group changes. Subgroups

include Select (S) and Operate (O).

GLOBAL (G):

One Global command performs operations that don’t fall into the other general

groups. The command for reading and changing passwords (GS-PW) is the only

global command available.

METERING (M):

Commands in this group report all real-time metering values. No subgroup is

used with metering commands.

REPORTS (R):

These commands read and reset reporting functions such as time and date,

demand registers, and breaker duty statistics.

SETTINGS (S):

This group contains all of the setting parameters that govern relay function.

Subgroups include Setting Groups 0, 1, 2, and 3, Protection Settings (P) not in

setting groups, Alarm Settings (A), Breaker Monitor Settings (B), General

Settings (G), and Logic Settings (L).

MISCELLANEOUS:

Miscellaneous commands include Access, Exit, and Help. Note that only the first

letter of these commands must be entered; entering the full command name is

optional.

Using the ASCII Command Interface
Human to Machine ASCII Command Operations

When using ASCII commands, settings can be read and changed on a function-by-function basis. The

mnemonic format of the commands helps the user interact with the relay. It isn’t necessary to remember

all of the object names. Most commands don’t require that you specify a complete object name. If the first

two letters of a command are entered, the relay will respond with all applicable object names.
ASCII Command Examples:

1. Obtain the breaker operations count by entering RB (Report Breaker). The BE1-851 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 operations, and 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 BE1-851.

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 the 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-toTQ=0,0m
