NCC# Description

NV array elements used as members of fblock array require a
starting index [NCC#446]
A functional block array declaration must have its members
implemented using network variable arrays. The network variable
arrays may be larger than the functional block array, and the indices
need not be identical (between the functional block array and the
various network variable arrays). The reference to each array
network variable in the implements statements of the member list
requires a starting index as part of the declarations in the
implements statements, to identify which array element of the
network variable corresponds to the 0
th
array element of the
functional block. The compiler then automatically distributes the
following elements of the network variable arrays to the following
elements of the functional block array.
447 The fblock reference requires an index[NCC#447]
Each element of a functional block array must be treated separately.
An index is always required to select an element of a functional block
array.

The fblock’s NV member array is not big enough for the FB
array[NCC#448]
A functional block array declaration must have its members
implemented using network variable arrays. The network variable
arrays may be larger than the functional block array, but may not be
smaller. The network variable array elements' indices need not start
at 0 in correspondence with the functional block array, but they must
be consecutive. Thus, the network variable array must be large
enough to accommodate the functional block array. For example,
consider the following improper declaration:
network output SNVT_volt v[4];
fblock SFPTwhatever {
v[2] implements memberV;
} fb[3];
The functional block array fb has three members, and the network
variable array v has four members. However, the declaration does
not use v[0] nor v[1], and it matches v[2] with fb[0], and v[3] with
fb[1]. There are not enough elements in the array v, because v[4]
would be needed for fb[2], but the array's last member is v[3].
449 The fblock or NV context requires an index[NCC#449]
A functional block array or a network variable array used as the
context (left-hand side) of the property operator :: must have an
index expression. An entire array cannot be used in this manner,
only an individual element.
