Many of the configuration parameters can be modified by the application logic during
runtime. These parameters are set initially when the hardware configuration is
downloaded, but can be modified during runtime to adjust to changing conditions.
Parameters are changed using two Word Parameter Write registers in %AQ memory. The
first word contains the parameter index number and the second word contains the
parameter value. One parameter can be changed per RX3i controller scan. Both %AQ
locations should be set to a value of 0 when parameter values are not being changed.
It is recommended that the %AQ Word 2 be set to the desired value first, followed by the
%AQ Word 1 being set to the index for at least one PLC scan. Then the %AQ Word 1
should be set to zero, followed by the %AQ Word being set to zero.

A negative value of the Grid 1 or Grid 2 nominal current (Parameter # 14 or #29) means that
the Grid's total active power under normal conditions is expected to have a negative sign. The
user is responsible for the correct PT/CT connections to get the negative sign for the active
power of each phase.
