Changing an IED's IEC 61850 configuration from IEC 61850
edition 2 to IEC 61850 edition 1 will remove the Access points that
are modelled in SCL except the default Access point and also if the
redundancy is modelled then it will also be removed.
Merging units
IEC16000090 V1 EN-US
Figure 30: Merging units tab
Access points should be configured before configuring merging units. This tab
allows configuring of the reception of data from merging units. Each row in this
tab corresponds to a merging unit. Changing settings in this tab will not have any
impact on the SCL model. The IED can be configured to receive IEC 61850–9–2E
sample value streams from merging units.
This tab's availability will be based on order-specification.
Migration of merging unit configuration from 670 2.0/2.1 to 2.2
series is not supported. From 670 2.2 series onwards, merging unit
modules can be created/deleted from the merging unit tab of ECT,
not from HWT.
