The connectivity package calculates an estimated application configuration load every time it is saved in Application Configuration or written to the IED. This functionality prevents too complex configurations from being used and possibly risking IED protection functionality.
Calculation results are divided into two different sections: OK and Error. At 100 percent, PCM600 can give either an OK or an error message because the connectivity package rounds the actual limit to the closest percentage. If the calculation result is above 100 percent, PCM600 always gives an error message and prevents writing the configuration to the IED as the configuration is too large for the IED to handle. The configuration is written to the IED if the result is below the error range.
