NCC# Description

422 Invalid property reference [NCC#422]

The item appearing in the property list is not a configuration

property.

423

The scope value of the LonMark Resource File reference is out

of range [NCC#423]

The valid range of the scope value is 0 .. 6. The compiler has

encountered a resource file containing a scope value that is out of

that range. Use the NodeBuilder Resource Editor to examine the

resource file and correct the scope value if possible, otherwise contact

LonSupport.

424

Function type not correct for a fblock director function

[NCC#424]

The director function for a functional block must be declared using

a specific function prototype. The function returns void, and it has

two parameters. The prototype must be in the form shown below:

void f (unsigned index, int cmd);

For more information, consult the Neuron C Programmer's Guide or

the Neuron C Reference Guide.

425 Director symbol is not defined or is not a function [NCC#425]

The initial declaration of the director function for a functional block

must appear prior to the declaration of the functional block. Since

the director function may very well make reference to the functional

block declaration, the initial declaration will probably need to be a

function prototype declaration, or a forward reference. For more

information, consult the Neuron C Programmer's Guide.

426 Too many fblocks declared [NCC#426]

The Neuron Chip can support a maximum of 62 functional blocks.

Note that each element of an array of fblocks counts as one

functional block.

427

The context for the ‘: :’ operator is not a valid context

[NCC#427]

The :: operator can be used to access the members and the properties

of a functional block, as well as the properties of a network variable,

or properties of the device. This message indicates that the context,

or the portion of the property expression that precedes the ::

operator, is neither a functional block nor a network variable. A

functional block array or a network variable array requires an index

expression in the context of the :: operator. To access device

properties, use the :: operator without a context preceding it. See the

examples and description of the :: operator in the Neuron C

Programmer's Guide and the Neuron C Reference Guide for more

information.

428

The specified fblock does not have a director function

[NCC#428]

An attempt to access the director property of the functional block was

made, but no director function was declared for the functional block.
