LOGIC NAMES
In order to easily identify the logic scheme that is operational in memory, each logic scheme is named. The
name is shown on the RELAY SETUP menu screen. For the custom logic scheme, the operator must enter
a name (a maximum of eight characters) identifying the logic scheme. When naming a custom logic scheme,
the standard logic scheme names can not be used. Only a unique name can be assigned to a custom logic
scheme. Custom logic schemes are programmed through the communication ports. Preprogrammed logic
schemes are selected through the front panel or the communication ports. A logic scheme is selected by
using the command LOGIC = <name> where <name> is the defined name of the logic scheme.
If a custom logic scheme is to be used, it is defined starting with the command LN = <name> where <name>
is the user selected name for the logic scheme.
To simplify making minor changes to an existing logic scheme, all logic equations for an existing scheme can
be copied over to the custom scheme by typing LN=<existing name>. Then the custom logic scheme must
be given a unique name by entering LN=<custom name>. Once the logic name is changed, the changes can
be made. (Changing the name does not affect the other logic definitions.) If changes are attempted prior
to changing the logic name, the relay will respond with an error message:

Defined name must be different from the
standard logic names. An existing logic
scheme can be copied into memory for
editing by using LN=<existing command>.

OUTPUT OPERATIONS
The BE1-BPR relay provides two types of outputs: virtual outputs and hardware outputs. The following
paragraphs provide information about the function and characteristics of virtual and hardware outputs.
Virtual Outputs
A virtual output exists only as a logical state inside the relay. Output operation for virtual outputs OA through
O12 is defined by boolean logic equations. Each variable in the equation corresponds to the current state
of an input, output, or timer. Any time a logic variable changes state, the outputs are reevaluated as TRUE
or FALSE. If a logical output corresponding to a physical output changes state, then the corresponding
output relay contact also changes state.
