Section 5 Configuring the IED and changing settings
5.1 Overview
The customer specific values for each setting parameter and a configuration file have to
be available before the IED can be set and configured, if the IED is not delivered with a
configuration.
Use the configuration tools in PCM600 to verify that the IED has the expected
configuration.
Each function included in the IED has several setting parameters, which have to be set in
order to make the IED behave as intended. A factory default value is provided for each
parameter.The Parameter Setting Tool in PCM600 is used when changing setting
parameters.
All settings can be
• Entered manually through the local HMI.
• Written from a PC, either locally or remotely using PCM600. Front or rear port
communication has to be established before the settings can be written to the IED.
Make sure that the DC supply is not turned off when the IED saves the
written configuration.
The IED uses a FLASH disk for storing configuration data and process data like counters,
object states, Local/Remote switch position etc. Since FLASH memory is used, measures
have been taken in software to make sure that the FLASH disk is not worn out by too
intensive storing of data.
This means, that to be absolutely sure that all data have been saved to FLASH, it is
necessary to leave the IED with auxiliary power connected after all the commissioning is
done (including setting the Local/Remote switch to the desired position) for at least one
hour after the last commissioning action performed on the IED.
After that time has elapsed, it will be safe to turn the IED off, no data will be lost.
