ASCII Command Communications
The BE1-951 relay has three independent communications ports for serial communications. A computer
terminal or PC running a terminal emulation program such as Windows® HyperTerminal® can be connected
to any of the three ports so that commands can be sent to the relay. Communication with the relay uses a
simple ASCII command language. When a command is entered via a serial port, the relay responds with
the appropriate action. ASCII command communication is designed for both human-to-machine interactions
and batch download type operations. The following paragraphs briefly describe the command structure and
discuss human-to-machine interactions and batch command text file operations. The operation of the ASCII
commands is described in detail in Section 11,
ASCII Command Interface.
Command Structure
An ASCII command consists of a command string made up of one or two letters followed by a hyphen and
an object name. The first letter specifies the general command function and the second a sub-group. The
object name is the specific function for which the command is intended. A command string entered by itself
is a read command. A command string followed by an equal sign and one or more parameters, is a write
command. The general command groups are organized into five major groups plus several miscellaneous
commands. These commands are as follows:
C
CONTROL. Commands to perform select before operate control actions such as tripping and closing
the circuit breaker, changing the active setting group, etc.. Subgroups include S for Select and O for
Operate.
G
GLOBAL. Perform global operations that do not fall into the other general groups such as password
security. Subgroups include: S for security settings.
M
METERING. Read all real time metering values. This general command group has no subgroups.
P
PROGRAM. Subgroup command to read or program a setting.
