NCC# Description

499

NV array element used as a property requires an index

[NCC#499]

A functional block declaration may have its properties implemented

using configuration parameters or configuration network variables.

A simple (non-array) functional block requires any configuration

property network variables to be simple NVs, or NV array elements.

These properties can either be simple network variables, or elements

of network variable arrays. In the case of an element of a network

variable array, an index expression must be part of the declaration in

the fb_properties list, to identify the array element to be used.

500

NV array elements used as properties of an array require a

starting index [NCC#500]

A functional block array declaration may have its properties

implemented using configuration parameters or configuration

property 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 fb_properties 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

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.

501

Non-shared NV used as property of array must itself be an

array [NCC#501]

A functional block array declaration may have its properties

implemented using configuration parameters or configuration

property network variable arrays. The non-shared properties using

network variables must be 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 fb_properties 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

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.
