REX615 IEC 61850 Engineering Guide

Data sets and control blocks must be defined in the SCL configuration phase under one LLN0. Dynamic creation is not supported.

The number of data set members and report controls should be kept within the limits of standard configuration offering. When adding data set members above the recommended defaults, the IED configuration may have different data priority/ speed.

Table 1. Possible errors if the imported FPN SCD file contains invalid data sets
Condition	Cause	Remedy
The customer IED contains [xx] data sets. The internal IED allows 27 data sets at maximum.	There are too many data sets in the configuration.	Combine or remove some data sets.
The customer IED contains one or more data sets having [xx] entries. The internal IED allows 80 entries at maximum.	One or more data sets in the imported configuration are too big.	Check the data set sizes on the editing dialog box for data set entries. Remove some entries or split data sets into multiple data sets if possible.
