Configuration load calculation

Connectivity package calculates an estimated application configuration load every time it
is saved in the Application Configuration tool or written to IED. This functionality
prevents too complex configurations from being used and possibly risking IED protection
functionality.
Calculation results are divided into three different sections which are OK, Warning and
Error. If the calculation result is 105% or more, the configuration is too large for the IED
to handle and PCM600 prevents writing the configuration to the IED. If the configuration
load is more than 100%, PCM600 gives a warning not to add 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.

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.
