 Description Note
(bit) 
EQ
1: if the data ranges are identical.
0: if the data ranges are not identical.

E1
Error output
1: if the number of elements exceeds the
source or target range.
The range limits are checked irrespective
of the edge change on the Boolean EN
input.
E2
Error output
1: if the source and target range overlap.
The range limits are checked irrespective
of the edge change on the Boolean EN
input.
E3
Error output
1: if the source or destination range are out-
side of the available marker range (offset
error, or input NO is not configured i.e. has the
value 0.
The range limits are checked irrespective
of the edge change on the Boolean EN
input.
