IEC 61850 Configuration Banks

To help version management and minimize down-time during system upgrades and
maintenance, the MiCOM IEDs have incorporated a mechanism consisting of multiple
configuration banks. These configuration banks fall into two categories:
−
−
Any new configuration sent to the IED is automatically stored in the inactive configuration
bank, therefore not immediately affecting the current configuration.
When the upgrade or maintenance stage is complete, the IED Configurator tool can be used
to transmit a command, which authorizes activation of the new configuration contained in the
inactive configuration bank. This is done by switching the active and inactive configuration
banks. The capability of switching the configuration banks is also available using the IED
GS
CONFIGURATOR column of the HMI.
The SCL Name and Revision attributes of both configuration banks are also available in the
IED CONFIGURATOR column of the HMI.
4.3.2

IEC 61850 Network Connectivity

Configuration of the IP parameters and SNTP time synchronization parameters is performed
by the IED Configurator tool. If these parameters are not available using an SCL file, they
must be configured manually.
As the IP addressing will be completely detached and independent from any public network,
it is up to the company's system administrator to establish the IP addressing strategy. Every
IP address on the network must be unique. This applies to all devices on the network.
Duplicate IP addresses will result in conflict and must be avoided. The IED will check for a
conflict on every IP configuration change and at power up. An alarm will be raised if an IP
conflict is detected.
The IED can be configured to accept data from other networks using the Gateway setting. If
multiple networks are used, the IP addresses must be unique across networks.
