5-54 Neuron C Compiler Errors (NCC)

NCC# Description

442

Existing LonMark SD string info for node will be overridden

[NCC#442]

When a Neuron C program uses any of the new Neuron C Version 2

features that support the construction of a L

ONMARK device, the

compiler will create the SD and SI information for the device. When

the compiler attempts to insert this information into the SI and SD

strings, if there is already text present from the user's program, the

compiler will insert the L

ONMARK information at the front of the

string, and will then use a semicolon character to separate the

automatically-generated string from the user-specified string.

If the compiler detects that the existing string information started

with the special characters that would identify that information as

LONMARK information, the compiler then issues this warning, to let

the programmer know that the existing L

ONMARK information in the

program was overridden.

443

Insertion of LonMark node SD info truncates existing string

[NCC#443]

When a Neuron C program uses any of the new Neuron C Version 2

features that support the construction of a LONMARK device, the

compiler will create the SD and SI information for the device. When

the compiler attempts to insert this information into the SI and SD

strings, if there is already text present from the user's program, the

compiler will insert the L

ONMARK information at the front of the

string, and will then use a semicolon character to separate the

automatically-generated string from the user-specified string.

If the compiler detects that the addition of this information will

cause the string to exceed the limit of 1023 characters, the compiler

will truncate the string and issue this message.

444

The fblock external name string is invalid or is too long

[NCC#444]

The L

ONMARK Application Layer Interoperability Guidelines state

that the external name of a functional block (the name which

appears in the L

ONMARK information in the node's SD string) shall

be 16 characters or less. There are certain restrictions to the set of

acceptable characters, too. See the guidelines document, referenced

above, for more information.

445

NV array element used as member of fblock requires an index

[NCC#445]

A simple (non-array) functional block declaration requires network

variable members that are not arrays. These members 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 implements

statement, to identify the array element to be used.
