IEC 61850 CONFIGURATION BANKS

To help version management and minimise down-time during system upgrades and maintenance, the device
has incorporated a mechanism consisting of multiple configuration banks. These configuration banks fall into
two categories:
● Active Configuration Bank
● Inactive Configuration Bank
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 IEC 61850 Configurator tool can be used to
transmit a command, which authorises 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 IEC61850 CONFIG. column of the HMI.
The SCL Name and Revision attributes of both configuration banks are also available in the IEC61850
CONFIG. column of the HMI.
3.5.2

IEC 61850 NETWORK CONNECTIVITY

Configuration of the IP parameters and SNTP (Simple Network Time Protocol) time synchronisation
parameters is performed by the IEC 61850 Configurator tool. If these parameters are not available using an
SCL (Substation Configuration Language) file, they must be configured manually.
Every IP address on the Local Area Network must be unique. Duplicate IP addresses result in conflict and
must be avoided. Most IEDs check for a conflict on every IP configuration change and at power up and they
raise an alarm 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.
