functionality to the configuration. The configuration is written to the IED if the result
is inside or below the warning range.
Some inaccuracy exists between the calculated load estimate and the actual load of an
IED when considering all parameters. This is why PCM600 does not prevent the
writing immediately when the estimated load exceeds 100%. The IED supervises its
performance continuously and indicates with self-supervision warning code 2 if an
actual performance risk is detected. It is recommended to verify the configuration load
also with an actual IED and actual settings when exceeding the calculation result of
90% or when using GOOSE on a larger scale.
The calculation result is only visible in PCM600 output window
inside Logging tab.

5.2 Parameter Setting tool
Configuration parameters and settings parameters can be changed with LHMI,
WHMI or with the Parameter Setting tool in PCM600.
Some parameters are only visible in the Parameter Setting tool and
some only in LHMI.
A common writing from PCM600 to the protection relay, where
parameters are changed in the Parameter Setting tool, overwrites any
parameter changes made locally with LHMI.
All parameters listed and displayed in the parameter list can be sorted into two groups.
• Configuration parameters
• Setting parameters
