The LON Network Tool is used for binding network variables between RED 500
terminals. Typically, LON is used for transferring status data between the terminals
for interlocking sequences running in the units, see Figure 4.1.2.3.-1 below and
Figure 4.1.13.8.-1 on page 67.

The rated frequency of the feeder terminal is set in association with configuration
via a dialogue box in the Relay Configuration Tool. The set rated frequency cannot
be changed afterwards via the HMI or serial communication, but it can be read via
the global control parameter "Rated frequency" of the feeder terminal.

The function blocks and I/O cards include a large number of parameters and events.
In addition, general parameters and events are provided, e.g. parameters for control
and communication as well as events for testing and self-supervision.
The function block specific parameters are listed in each function block description.
Moreover, all parameters and events for REF 54_ are listed in the parameter and
event lists. The function block descriptions as well as the parameter and event lists
are included on the CD-ROM "Technical Descriptions of Functions" (refer to
section "References" on page 96).

To ensure that a protection function block protects the feeder in the desired manner,
the default values of parameters are to be checked and properly set before taking the
function block into use.
The parameters can be set either locally over the HMI or externally via the serial
communication.
